Bringing a pre-1884 era CPF Bent Billiard Back to Life

Blog by Steve Laug

My friend John gave me an old pipe that needed to be restored and it fits well into my collection of older CPF pipes. This one was a CPF bent billiard with the CPF logo in an oval and the word French arched above it and the word Briar arched below it. On the gold band around the shank were false hallmarks and the CPF logo in an oval. It was an old timer with the orific style button on a horn stem. The tenon on the end of the stem was bone and in excellent shape. The threads on the tenon were perfect and the tenon looked almost new. However, the threads in the shank were worn and would not hold the stem in place. It could be spun around and with a slight wiggle it came out of the shank. The threads on the tenon no longer aligned with the threads in the shank. The horn stem itself had some tooth chatter on both sides of the stem near the button and was dirty and tired looking. The finish on the bowl was in great shape. The bowl itself had been reamed but there was a light coat of ash in the bowl. The rim looked like it had been topped somewhere in its life but whoever did the work did it well.

I have written a blog about the history of the brand previously. You can read it for details at this link: https://rebornpipes.com/2013/04/14/some-reflection-on-the-historical-background-on-cpf-pipes/

For the sake of summary I include a portion of that blog here.

CPF stands for Colossus Pipe Factory. There is not much known about the Colossus Pipe Factory. I learned that by the mid 1890’s CPF was owned by Kaufman Brothers & Bondy (KB&B). They operated the factory at 129 Grand Street, in New York City, New York. I had a faint memory of some connection between CPF and Kaufmann Brothers & Bondy. But was unsure where I had heard or read that. In the process of reading information I came across this post by Bill Feuerbach on the Kaywoodie Forum it read as follows: “About 10 years ago I picked up two original invoices from KB&B. One is dated February 5, 1884 and the other December 9, 1898. Both have the address as 129-131 Grand Street, which is in Soho, adjacent to the Bowery in New York City. The 1898 invoice has in the upper left hand corner the initials CPF and Trademark. So by 1898 KB&B was making it known to the trade that they owned the CPF trademark. The 1884 invoice does not have CPF on it. Therefore I think we can assume KB&B acquired or started the CPF line sometime between 1884 and 1898.”

Thus we know that the brand was purchased by KB & B sometime between 1884 and 1898 and that it continued until 1915. That time frame gives help in dating some of the older CPF pipes you or I might find. It can be said that prior to the dual stamping it is fairly certain that the pipe is pre-1884 to 1898. After the dual stamping it can be placed post 1898 until the closure of the brand line in 1915. CPF made beautiful pipes. I believe Sam Goldberger was correct in his assertion of the potential carvers that made the pipes being of European training and the classic shapes and well aged briar. That coincides with all the CPF pipes that I have come across.

The pipe I got from John is one of the earlier pre-1884 as it only bears the CPF stamp in faded gold leaf on the shank. I took the stem off the shank to look over the connector in the shank. The threads were worn and there was a chunk of briar missing from the bottom side of the shank exterior inside the band. There also appeared to be a crack at the top of the shank but it turned out to not be a crack but rather an area where the end of the shank is stepped down. I filled in the hollow area with wood glue and used the dental pick to push it down in the divot area.

I tried several methods for dealing with the damaged threads in the shank. The first of these was to build up the tenon with wood glue and then also with super glue. Both methods failed. As soon as I twisted the tenon into the shank the threads were stripped of all of the glue buildup. Those two methods utterly failed. I cleaned off the tenon with alcohol on cotton pads and started over. I examined the threads in the shank and it suddenly dawned on me that I could build them up. I carefully used super glue on the threads keeping it totally out of the airway in shank. I filled in the threaded area with the glue and once it dried I was able to recut the threads with the bone tenon itself. The repair worked and the stem fit snugly in the shank.

I have learned over the years that using micromesh sanding pads on horn stems really raises a shine and brings out the grain in the horn. I started by wet sanding this one with 1500-2400 grit micromesh to take care of the tooth chatter and to reshape the oval button. It took some sanding but I finally got is shaped correctly. These first three grits of micromesh do the hard work in polishing the horn. When I finished I rubbed it down with Obsidian Oil. You can really begin to see the bands in the horn and the grain. This was one beautiful piece of horn. I dry sanded the stem with 3200-4000 grit pads and the grain began to really show and glow. I love the translucence of horn once it begins to really shine. This stem was truly a beauty to behold. I rubbed it down again with Obisidan Oil before moving on to the next grits of micromesh. I finished with the 6000-12,000 grit pads – dry sanding through each grit. I then buffed the stem lightly with the Blue Diamond Plastic Polish to give the final shine. I rubbed down the bowl with a light coat of olive oil and then cleaned up the band on the stem with silver polish and micromesh sanding pads. I finished the band by buffing it with a jeweler’s silver polishing cloth. The next photo shows the stamping with the gold leaf on the shank and also gives a clear photo of the stamping and faux hallmarks on the band. I buffed the pipe with multiple coats of carnauba wax and then gave it a final buff with a clean, soft flannel buffing pad to raise the shine. The finished pipe is shown below. Note the glow of the horn stem and the contrast of the brass/gold band. This old timer is ready for many more years of service. If you have not smoked a horn stem pipe you have to give one a try. They are a totally different experience from vulcanite or Lucite. They are comfortable and light in the mouth. I am looking forward to breaking this one in again and enjoying smoking it.

Bringing a Comoy’s Grand Slam 5 Straight Bulldog Back to Life

2 Replies

Blog by Steve Laug

The next pipe on my worktable was a Comoy’s Bulldog. Personally, I think Comoy’s nailed the straight bulldog shape better than most others. It is a perfect bulldog shape and it is a pleasure to hold and smoke. The stamping on the left side of the shank reads Comoy’s over Grand Slam over Pipe. On the left underside of the shank next to the stem it is stamped X7. On the right topside it is stamped in the classic circle reading Made in London with the “in” in the centre of the circle. Underneath the circle it reads England. Further up that side of the shank is a number 5 stamped almost next to the bowl. I examined the C-inlay on the stem to see how it was made. I have learned over time and through research on these pipes that if it’s been applied in three steps, then it was made pre-1980. This one was indeed a three-step C-inlay. Thus I knew it was made earlier than 1980.

Like all of the pipes I work on, I took a moment to give the pipe a quick assessment. Before I even start the clean up and restoration I take time to look it over to make sure I see what I have to deal with on a particular pipe. The examination helps me to plan how I am going to address the issues on this particular pipe. The Comoy’s pipe was definitely in need of some TLC. The original finish on the Grand Slam Pipe line was rich and full of life. The contrast of dark stain that highlights the grain and the top coat of stain that varies from a rich red to a dark golden combine together to give a very beautiful finish. There were no major dents in the briar that needed to be addressed, though there was a small one in the shank near the stem junction on the sharp edge on the right side that could not be repaired. The briar itself was lifeless and faded looking dull and flat. There was some dirt and grime on it and particularly at the bowl shank junction. The rim had a thick coating of tars on top and some minimal damage to the inner bevel. The bowl had a light cake and seemed to have been reamed recently. It would need to be tidied up.

The stem was badly oxidized and had tooth marks on the top side and the underside near the button. The slot was partially plugged and would need to be opened.

I cleaned up the bowl with a wipe down of alcohol on a cotton pad to remove the dirt and grime and begin to soften the tars on the rim. I gave it a light sanding with 1500 grit micromesh sanding pads. Then I wiped it down once more with the alcohol and cotton pads. The buildup was just about gone. Just a little more scrubbing and the rim was finished. I lightly sanded the stem with a medium grit sanding sponge to loosen the oxidation and then dropped it in a bath of Oxyclean to soak overnight. In the photo below you can see the oxidation begin to run off the stem into the white bubbles of the Oxyclean mixture. The next morning when I took it out of the bath the mixture was yellow with the oxidation. I dried off the stem with a coarse cotton towel to remove the softened oxidation. The stem was much cleaner and black of the vulcanite was beginning to show. I put the stem on the shank and sanded it with 220 grit sandpaper followed by a medium grit sanding sponge to remove the oxidation that had come to the surface after the soak.

I wiped it down with Obsidian Oil and then took the following photos of the stem to show the progress so far.

I cleaned out the deep tooth mark on the underside of the stem with a dental pick and then a cotton pad and alcohol. Once it was clean I used clear super glue to make a patch on the marks. I over filled the repair so that it would dry and not shrink too much requiring a second coat. I set the repaired stem aside to dry for the day while I was at work. After work I sanded it smooth with 220 grit sandpaper and then with a medium and a fine grit sanding sponge. When the surface of the repair matched the stem material the sanding was finished. I then used a flat blade screw driver to unscrew the end of the stinger in the tenon. The cap on the end held a replaceable leather washer in place. Once the cap was off I was able to remove the washer. I then used a pair of needle nose pliers on which I have covered then ends with a thick wrapping of scotch tape. This provides a cushion when grabbing onto metal. The stingers in the Grand Slam were threaded and I heated the metal tenon until the goop holding it tight was loose. I turned it with the pliers until it was free of the tenon. With all of the parts removed from the stinger I cleaned it with a soft bristle brass tire brush to clean off the tars. I cleaned out the interior of the stinger with pipe cleaners, cotton swabs and alcohol. I used the brass brush to also clean the threads on both ends of the stinger. When I had them cleaned I used coated the threads on the front of the stinger with a light coat of Vaseline to protect it and lubricate them when I turned the cap onto the end. I had cleaned it with some soap and warm water and then used the Vaseline to give it some life. With it all cleaned and lubricated I put it back together and set it aside while I cleaned the shank and the stem. I used the drill bit on the KleenReem pipe reamer to clean out the airway from the end of the mortise to the bottom of the bowl. It had almost closed off with the tars. The draught on the shank was very constricted. Once I had run the bit through it several time cleaning out the buildup the draught was open and unrestricted. I cleaned out the shank and airway with alcohol on cotton swabs and pipe cleaners. Once they came out clean the shank was finished and ready for the stem.

I cleaned out the stem with pipe cleaners and cotton swabs while I had the stinger out. I was able to remove all of the buildup in the stem and then put it all back together again. The stinger end was lubricated and then threaded back into the tenon. It sits quite deep in the tenon and has a small flange that sits against the tenon end. Here are some photos of the stinger in place in the stem.

I used a 1500 grit micromesh pad to further polish the aluminum of the stinger. I sanded the stem with micromesh sanding pads – wet sanding with 1500-2400 grit pads and dry sanding with 3200-4000 grit pads. Between the first set of three pads and after the second set I rubbed the stem down with Obsidian Oil. When it dried I buffed the stem with White Diamond on the wheel to polish the vulcanite. I brought it back to the worktable and gave it a further coat of Obsidian Oil.

I finished dry sanding with 6000-12,000 grit micromesh sanding pads. I rubbed the stem down a final time with Obsidian Oil and buffed it with Blue Diamond Plastic Polish on the buffing wheel. I buffed the pipe with Blue Diamond and then gave it multiple coats of carnauba wax. Between each coat of wax I buffed it with a clean, soft flannel buffing pad to raise the shine. The photos below show the finished pipe. It is cleaned, polished and ready for that next inaugural smoke.

Midterm Exam #2: Repairing the Leaky Airway on a Champion Deluxe

4 Replies

Blog by Anthony Cook

It’s exam day again. I didn’t get much sleep, but I did have a good breakfast of Pop-Tarts and leftover ramen. So, let’s do this! This time, the exam is based on a bent brandy shaped Champion Deluxe.

PipePhil provides a little info on the Champion brand: The pipe I’m working with has shank stamping and a stem logo that is identical to the middle pipe in the above graphic. The country of origin for the brand is listed as Switzerland, but there must be some French connection. The word “FRANCE” is stamped across the bottom of the shank-end of the stem on my pipe. You can see the pipe for yourself in the photos below, which were taken shortly after its arrival. I was really pleased with this one when it arrived. I really liked the size, shape, and rustication pattern. As I turned it over in my hands, it seemed to be in pretty good condition. There were no major cracks or gouges, only a generous amount of grime on the stummel, one or two nicks on the rim, and a little oxidation on the stem. I thought it would clean up nicely and was beginning to look forward to working on it.

Then, I pulled the stem out to check the internals and cringed… The airway was drilled so high that it actually penetrated the top of the mortise and only a very thin layer of briar remained between it and the surface of the shank. In fact, the wood was so thin that it had either cracked from heat/moisture expansion or had been punctured by the rustication tool. If you look closely, you can see in the second image that the alcohol from a dampened pipe cleaner would seep out of the airway to the surface of the shank.

I didn’t have the confidence at the time to attempt to repair something as essential and delicate as an airway. So, I reamed the bowl, scrubbed the inside of the shank and stem clean, and then dropped it back into the box where it’s been withering away for several months. So, today I pulled it back out for my second midterm exam.

The airway needed to be sealed before doing anything else. If that wasn’t successful any other work would be pointless. So, I clamped the stummel upside-down in my bench vise using a couple of foam strips to cushion it. I tried to make sure that the airway was as level to the ground as possible. Then, I applied super thin CA inside the airway with an applicator bulb. Since I couldn’t really see inside the shank and bowl, I had previously measured the length of the airway and marked it off on the applicator with a strip of tape. This, along with a slow and steady hand, kept me from dribbling the CA into the bowl. Once I was sure that the glue was completely dry, I used 240-grit and 320-grit sanding needles to smooth out any lumps and bumps that the glue may have created in the airway. Then, I prepared my initial test of the patch. I dampened a pipe cleaner with alcohol and inserted it into the airway. I couldn’t see any seepage, but just to be sure I pulled out my jeweler’s loupe to give it a closer inspection. Still nothing. The patch had passed its first test. I set up a retort for the next test. If there were any open fissures in the shank, the evaporation from the boiling alcohol would surely seep through. I flushed the shank 10-12 times before setting the pipe aside to cool. The color of the alcohol in the tube is a testament to the merits of a retort. It’s not filthy by any means, but remember, this is a pipe that I once thought was clean.

While the pipe rested, I closely inspected the shank to see if the patch had held. Success! I found no moisture seepage at all. The patch was doing its job and the worst part of the exam was over! After another dozen or so flush with the retort the alcohol in the tube was almost completely clean. I let the pipe cool, and then gave it a final, quick scrub the wrap up the internal cleaning. I placed the stem into a bath of warm water and Oxyclean and let soak for about an hour before I scrubbed it down with cubes cut from a Magic Eraser pad to remove the oxidation. Once the stem was clean, I applied a black CA glue patch to the remaining dents. I put a drop of activator on the patches to speed up the drying and they were ready to be worked again in about ten minutes. I sanded out the patches with 220-grit (the bottom image in the picture below), 320-grit, and 400-grit paper. Then, I gave the entire stem a light sanding with 600-grit paper to remove any minor scratches. The paint in the stem logo was cracked and flaking. So, I picked out the loose paint, and then I began to fill in the area around the logo with a grout pen begin restoring the logo. I was a little worried about how well this was going to turn out since the recessed stamp was very narrow and shallow. I let the “paint” dry for about 20 minutes before carefully sanding it down with 1200-grit paper and I thought that it came out surprisingly well in the end. I finished up work on the stem by lightly sanding it with 1200-grit paper to even everything out, and then polished with micro-mesh pads 1500-12000. The stem was finished and the clock on the wall was ticking. Some of the other guys were already turning in their papers. So, it was time to start wrapping things up. I mixed up a 3:1 stain solution of isopropyl alcohol and Fiebing’s black dye and applied it to the stummel. Then I buffed the entire stummel with red Tripoli before sanding out the scratches around the stamping with 400-grit, 600-grit, and 1200-grit sandpaper. Then, I applied a 3:1 dilution of Fiebing’s cordovan before polishing the stamping area with micro-mesh pads 3200-12000. I reattached the stem and gave the entire pipe a light buff with white diamond, and waxed the pipe with Halcyon II for the stummel and a few coats of carnauba for the stem. Finally, I applied a bowl coating to promote cake growth, and then turned the exam in with my fingers crossed.

The photos below show how it finally turned out. For some reason, in these photos the cordovan and black blend together in the rusticated areas making them appear much darker. When you have the pipe in hand the cordovan is much more evident. I don’t know why that is. Man, I hope we aren’t being graded on our photography skills as well.

But, wait..!

Okay, I realize that this is a little unusual for an exam, but I’d like to make a bit of a revision. You see, when I ran my first bowl through this Champion the draw was extremely poor and it gurgled so badly that it sounded like an aquarium. To be honest, this wasn’t unexpected. The misalignment of the airway between the mortise was so extreme that it couldn’t help but create a lot of turbulence, and therefore a lot of moisture. I couldn’t let that stand. So, I took the stem back to the worktable to tweak it a little.

I clamped the stem in the vice and used a Dremel to cut off the stepped end of the tenon. You can see the piece I removed lying on top of the vice in the photo below. After that, I sanded the face of the tenon smooth and level, and then used a tapered abrasive point in the Dremel to begin funneling the airway. I kept the airway lubricated with mineral oil to prevent the friction from burning or melting the vulcanite. The abrasive point opened up the end of the airway to a 3/16” diameter but transitioned it down to the 1/8” diameter of the original airway. Then, I used 240-grit and 320-grit sanding needles to make sure the transition was smooth. Finally, I used a round abrasive point to create a ¼” diameter chamfer on the tenon face around the airway and the sanding needles again to round off any of the sharp edges. In the picture below, the left image shows the step that I removed balanced on top of the stem for comparison; the right image shows the completed tenon after being reworked. I was eager to try it out and the results were amazing for such a simple modification. The bowl smoked all the way to the bottom with no gurgle at all; even when I intentionally tried to build up steam by puffing rapidly (it was for the sake of science). After the pipe had cooled, I removed the stem and found a lot of moisture in the mortise. So, the extra space below the airway was acting like the sump/well of a system pipe. Very cool. The pipe was once again looking good and smoking well. My second exam was in the bag.

Restoring a 1967 Dunhill Oom Paul 591

Blog by Steve Laug

The next one to my work table was a Dunhill Oom Paul 591. It was a Dunhill shape that I had not seen before. The stamping on the left side showed the shape number 591 next to DUNHILL over BRUYERE. On the right side of the shank it was stamped Made in England7 and next to that Circle 4A designating the size of the pipe. From several sources I was able to ascertain that the pipe was made in 1967. The finish on this one was in good shape. There was a light build up on the top of the rim and there was an uneven cake in the bowl. There were some small dents in the sides of the bowl but not enough for me to steam them out and risk harming the original finish. The stem would not fit down into the shank. In the pictures below you can see how far it would go into the mortise. I removed the stem and the mortise was dirty and black. The stem was oxidized and had some minimal tooth chatter on the underside near the button. There was also a shallow tooth mark on the underside amidst the chatter.

I cleaned out the shank with pipe cleaners, cotton swabs and isopropyl alcohol until the swabs came out clean. I cleaned the airway to the bowl and gave the bowl a light reaming to remove the uneven build up. I scrubbed down the rim and removed the light build up that was there and polished the bowl with carnauba on the buffer. I lightly sanded the stem with a medium grit sanding sponge to loosen the oxidation and with 220 grit sandpaper to remove the tooth chatter and small dent.

I mixed up a batch of oxyclean and put the stem in the bath to soak overnight. In the morning I took the lid off the container and removed the stem. The water had turned amber coloured. The oxidation had risen to the surface of the stem and I rubbed most of it off with a coarse cloth. I cleaned out the stem with alcohol and pipe cleaners and used the dental pick to clean out the slot on the stem. I sanded it with a medium and a fine grit sanding sponge to remove the softened oxidation. Then it was time to polish it with the micromesh sanding pads. I wet sanded with 1500-2400 grit pads and dry sanded with 3200-12,000 grit pads. I rubbed the stem down with Obsidian Oil between each set of three pads. I buffed the stem with red Tripoli after I finished with the 2400 grit pad and with White Diamond after the 12,000 grit pad.

There were still some scratches that showed up in the bright light of the flash so I worked it over again with the last set of pads and then buffed it with Blue Diamond Plastic Polish on the wheel. I finished by giving the bowl and stem multiple coats of carnauba wax and then buffing it with a clean, soft flannel buffing pad to raise the shine. The finished pipe is shown below. Somehow in the photos the fluorescent lights lend the photo a yellow tint that I normally do not get. The stem is absolutely shiny and black and the bowl is a rich oxblood red. It is ready to be smoked and enjoyed.

Restoring an Ascorti Business KS Bent Brandy with a broken stem

4 Replies

Blog by Steve Laug

The next pipe that I have on my work table was an Ardor Business KS Bent Brandy with severe damage to the end of the stem. The bowl still had some unsmoked tobacco in the bottom half and the cake was crumbly and concentrated around the middle of the bowl. The top portion of the bowl had a light cake. The bottom portion was fairly clean. The shank and stem were dirty with a lot of black tars and oils. The mortise was black and the airway from the bowl entered the mortise quite high. Part of it was actually above the mortise – very different angle of drilling. The tenon was flared on the end so that the smoke was funneled into the stem. The finish was in excellent shape – the rustication had a reddish top coat over a dark brown/black undercoat. Even the rim was clean and undamaged.

The stem has the same stepped look as the Caminetto Business pipe that I just completed. The saddle portion of the stem was flawless. The top of the stem and the underside were damaged near the button. There was a large chunk of the Lucite missing on the underside and there were some deep tooth marks on the top side. The button itself was gnawed on as well on the top side. I had some choices to make with regard to this stem. Should I try a patch on the large missing chunk from the stem or should I cut of the stem and reshape a new button? That was the big question on this stem. I took the next two close-up photos to give a clear idea of how badly the stem was damaged.

I measured the length and took pictures to get a feel for the look of the pipe with the present stem length and with the shortened length. When I had a good picture in my mind of how it would look I used my Dremel and sanding drum to remove the damaged portion of the stem and cut it back to where the undamaged stem material would allow me to shape a new button and slot.

I took the next photos of the pipe with the shortened stem to see what it looked like with 1/2 of an inch cut off the length.

I took the next two photos of the cut off end to show how I had worked the Dremel to give it a straight edge. Once I took it back to the work table I would work on cutting in the edge of the button and start giving it shape.

I used some black super glue to fill in the deep tooth marks that remained on the stem and also ran a small band of super glue along the area where the button would eventually be cut.

When the glue dried I used a flat blade needle file to cut the sharp edge of the button on the end of the cut back stem.

I used a knife edged needle file to carve back the thickness of the stem to the newly cut straight edge. I wanted a taper from the bend back toward the sharp edge. It takes some work to carve back Lucite, as it is significantly harder than vulcanite.

As I examined the end of the stem I realised that I did not have enough thickness to the material on the top and bottom of the airway. It would not allow me to go deep enough to have a good edge on the button. I decided to build it up and created the button thickness I needed. I used a mix of activated charcoal dust mixed with black super glue to make a putty like substance that would stick to the stem. Using a suggestion from Andrew Selking, I wrapped the end of the stem with scotch tape to create a straight edge to work against when I put the putty on the stem. I then gave the stem a light coat of black super glue and then used the dental pick to press the charcoal and super glue mix on the stem end against the scotch tape. I used a flat dental trowel to flatten the material in place and save some sanding for myself. When the repair was hard to the touch I removed the scotch tape and found that I had a fairly thick button built up on the stem end and that it had a pretty sharp edge to it.

I sanded the newly built button with 220 grit sandpaper to begin shaping it. I would have to use the needle files to sharpen the edge of the button and then sand the new button to shape it more like the one on the Caminetto stem that I had worked on previously. I was using it as the pattern for the shape and look of this one.

When I had it shaped as much as I could without damaging it I set it aside to cure over night and then worked on the bowl. I used the dental pick to remove the remaining third of a bowl of tobacco that was in the pipe. Once that was gone the bowl needed a good reaming. The shape and detail of the cake in the bowl can be seen in the next photo. I used the PipNet Reamer with the smallest cutting head to start reaming the bowl and worked my way up to the third cutting head which was the closest I had to the diameter of the bowl. It was a deep bowl and took time to remove all of the cake. The middle portion of the bowl had a hard cake. I worked it with the second cutting head until I finally was able to cut through it. I used the third head to work the cake back to bare briar. I also used a sharp pen knife to clean out the area in the bottom third of the bowl where the cutting head left behind a ridge of cake.

The next day I did not get to work on the stem as it was a heavy day at work and we had meetings into the late evening so the stem sat for two days. When I finally got the time to work on it I decided to start with shaping the slot and the button from the end view. I started by sanding the end of the stem with 220 grit sandpaper to smooth out the end and give me a flat canvas for cutting the slot with needle files. I began to work on the airway with an oval shaped needle file to begin to open the airway and create a flare in the slot. I also used and fatter oval needle file and a round file to further open the lot and the flare in the end. It took a lot of file work to get it to the place that is shown below. You can begin to see the Y shaped slot taking form. There is still a lot of filing and sanding to do at this point. I worked on the slot area with the needle files for probably 1 hour at this point and the photo below shows the result of the methodical filing and shaping. It is coming along but needs to be more open and the top and bottom edges of the slot need to be smoothed out around the air hole. I folded a piece of 220 grit sandpaper when I was able to insert it in the newly cut slot and worked on the shape and smoothness of the Y. I also sanded the face of the button to remove the scratches and marks that were there. The second photo below shows the shape of the slot and the button. It is very close to the one I was copying on the Caminetto.

I finished the end of the stem and the slot with micromesh sanding pads. I wet sanded with 1500-2400 grit pads and dry sanded with 3200-12,000 grit pads. I buffed the end of the stem with White Diamond. The finished slot is shown below. After I finished shaping the button and the slot from the end view it was time to work on the top and bottom edges and the overall look of the new button from both points of view. I sanded them with 220 grit sandpaper to shape and flatten them and then used a flat needle file to sharpen the edges on both sides. I really wanted the new button to look seamlessly part of the stem. It took a bit of work to sculpt it to the right shape. I then sanded it with a medium and a fine grit sanding sponge. When I was finished with the shaping and sanding I began to work on it with micromesh sanding pads. I wet sanded with 1500-2400 grit pads concentrating on the flat surfaces and the sharp edges first and finishing with the end of the button and slot. The wet sanding revealed more scratches and a bit more shaping that was needed to the edge of the button so I worked it over again with the medium and fine grit sanding sponges before going back and repeating the wet sanding with the first three grits of micromesh pads. I rubbed the stem down with some Obsidian Oil and when it dried, I dry sanded it with 3200-4000 grit micromesh. I dry sanded with the last three grits of micromesh – 6000, 8000 and 12,000 grit pads. I rubbed the stem down with Obsidian Oil and let it dry before taking it to the buffer. I buffed the stem with Blue Diamond plastic polish on the wheel and then gave the stem several coats of carnauba wax. I finished by buffing it with a soft, clean flannel buff to raise the shine. I gave the bowl a light buff with the carnauba and also with the soft flannel buff. The finished pipe and reshaped button is shown in the photos below.

Midterm Exam #1: Repairing a Cracked Bowl on a Pre-1956 Medico Billiard

12 Replies

Blog by Anthony Cook

The photo above represents the start of my first semester at the University of Reborn Pipes (by the way, Steve, we need T-shirts, a mascot, and a fight song). It was taken several months ago and it shows the first batch of pipes that I had collected for restoration practice. It’s a motley crew to be sure, but I have a special fondness for each of them. You never forget your first, as they say.

I’ve completed the restoration of the majority of these since the photo was taken (sadly, I failed the cob test, but it was rigged I tell you), but four of them were placed back into the box after cleaning and have remained there. Those four had issues that required either tools, materials, or experience that I just didn’t have at that point. Over time, other pipes attracted more of my attention and those remainders continued to linger in the dark and gather dust once again.

Now that I’ve acquired a few credit hours, I thought it might be time to drag them back out into the light; sort of as midterm exams to see if I’ve learned anything. The pipe that is second from the right in the group photo above is the one that I selected for my first exam. It’s an unnamed Medico billiard. The stamping on the shank reads simply “MEDICO” over “IMPORTED BRIAR” and the stem bears the “F” stamp found on some older Medicos. I learned from Dave Whitney, author of Old Briar, that the “F” stamp was probably discontinued in 1955, which gave me some idea of the pipe’s age.

The main reason that this one was shuffled back into the box was because of the extensive damage to the bowl. There were large fills within the carved rustication on the right side and several cracks had developed in the area both outside and inside the bowl. I discovered during cleaning that at least one of them penetrated completely into the chamber.

Below, you can see more of the original pictures that I took of the pipe shortly after it arrived. I had not done anything with it other than ream the bowl at the time these photos were taken.

As I mentioned, I had already cleaned the internals of the pipe before dropping it back in the box. So, I started work by dropping the stummel into a jar of alcohol to soften the lacquer finish. The metal ferrule at the end of the shank was loose enough to fall off. So, it was removed it and set aside. After a couple of hours, I removed the stummel from the bath and wiped it down with a cotton cloth. Then, I used acetone and #0000 steel wool to remove the lacquer coating. I also picked out the pinkish-orange putty from the fills, and then used the pick to scrape any loose or charred wood from the cracks. A lot of scratches and gouges were revealed once the rim was clean. So, I set up my topping surface and lightly sanded the majority of the blemishes away using 220-grit and 320-grit sandpaper. I mixed together powdered pumice, activated charcoal, and sodium silicate to make a bowl patch. After protecting the airway with a pipe cleaner, I applied a small amount of the patch mix directly to the cracks with a flat toothpick and firmly tamped to push it into the cracks. Then, I used the scoop on my pipe tool to apply a thin layer across the entire area for protection. Next, I addressed the cracks and pits on the outside of the bowl by filling them with a few layers of briar dust and CA glue. I applied the glue with the end of a toothpick to avoid getting glue into the carved areas as much as I could. After the patches had dried, I sanded them down with 220-grit and 320-grit sandpaper. The same progression of grits was used to put a slight chamfer on the outside of the rim to remove the gouges that remained there. While I was working the bowl, I also sanded the chamber patch smooth with 400-grit paper. I sat the stummel aside for a time to pay some attention to the stem. There was a lot of chatter near the button and tooth dents on both sides of the stem. I applied black CA glue (medium thickness) to the dents with a toothpick and dripped a couple of drops of activator over it to set it up quickly. When it was completely dry, I sanded out the glue patch and leveled the chatter with 220-grit paper. The two photos below show the patch before and after rough sanding. While I was working, I decided that I didn’t like how worn and rounded the edge of the button had become. So, I decided to build a new, sharper edge. I wrapped clear packing tape around the stem to mask it just below the button. I built up the layers until it was the depth that I wanted my new button to be. Then, I used a flat toothpick to “paint” black CA glue (thick) along the edge of the mask and dripped activator over it when I was satisfied with the coverage. Before the glue could completely set up, I quickly peeled the tape away to reveal my new (although rough at this point) button edge. I used 220-grit paper and a sanding file to start shaping the button, and then 320-grit and 400-grit to refine the button shape and further blend the patch area. I also used 400-grit paper to remove the unsightly (to my eyes) molding seams along the sides of the stem. I placed a rubber washer over the tenon to preserve the sharp edge of the stem face and lightly sanded the entire stem with 600-grit and 1200-grit paper. The stem logo was in fair condition, but the paint was cracked and discolored. So, I filled it in using a grout pen and carefully sanded off the excess with 1200-grit paper. The grout paint left a slight, white residue smeared around the logo, but that would be removed with further polishing. Before polishing the stem, I rubbed it down with a drop of mineral oil, let it sit for a couple of minutes, and wiped it away. I hoped that this would moisturize the surface a bit and maybe prevent some of the nylon fiber splintering that always seemed to leave behind fine scratches in the finished stem. Then, I polished with micro-mesh pads 1500-grit to 12000-grit. I added a second and third drop of oil between 2400/3200 and 4000/6000 pads. I was pretty pleased with the results. The final stem was much more blemish-free that the previous nylon stems I’ve worked on.

With the stem finished up, I returned to the metal ferrule that I had set aside earlier. I gave it a once over with #0000 steel wool, and then polished it with Semichrome polishing paste and a soft cloth. I buffed of the excess with my Dremel and a small buffing wheel to give it a nice shine. Back to the stummel, I applied a 3:1 mixture of isopropyl alcohol and Fiebing’s black dye, hand-buffed the stummel with a soft rag to remove the excess, and then used 600-grit paper to remove the scratches and most of the dark stain except for inside of the carved rustications and what had set into the grain. I also made small adjustments to the width and angle of the rim chamfer with the sandpaper to make sure that it was even all the way around.

Next, I applied a 3:1 stain solution of isopropyl alcohol and Fiebing’s dark brown, buffed off the excess by hand, and lightly sanded the entire stummel with 1200-grit sandpaper to smooth the surface and soften the edges of the rim. Then, I applied a 3:1 solution of ox blood stained and hand buffed again.

Finally, I polished the stummel with micro-mesh pads 1500-2400 before applying a 4:1 mahogany dye mix. I wiped the stummel down with an alcohol dampened cloth until I achieved a dark copper color and finished up by polishing with the remaining micro-mesh grits. Then it was time to put all of the pieces back together and give the pipe the final touches. I reattached the ferrule to the stummel with some 5-minute epoxy. When that had set, I applied a bowl coating mix of sour cream and activated charcoal to help promote the cake formation in the repaired chamber. I let that dry for about two hours before reattaching the stem and taking the pipe to the buffer. I buffed the stummel and stem with White Diamond, and then I gave the pipe several coats of carnauba wax.

With all of that done, I turned in my first exam. I’m feeling pretty good about it, but I never really know how I’ve done on these things until the grades finally come back. I’m not going to worry about it now, though. I still need to cram for the second exam. It’s going to be a long night.

Rejuvenating a Caminetto Business Long Shank Stack

Blog by Steve Laug

I just finished working on a long shank Caminetto Stack. It is stamped on the left side of the shank Caminetto Business. On the right side of the shank it is stamped Ascorti over Radice over Cucciago over Cantu Italy. Next to it is a shield. The finish is a rustication that looks very much like the older Castello Sea Rock finish. The bowl needed a thorough reaming to clean out the remnants of the old cake. The internals of the shank will also need a thorough cleaning. The pipe has a strong English smelling ghost that would need to be exorcised by a retort treatment. If that did not kill it then it would need to be given a cotton ball and alcohol treatment to further remove the ghost. The inner and out rim edges look really good. There is a build up tars and oils in the rustication on the top of the rim that will need to be scrubbed out. The deep rustication is also harbouring a lot of dust in the crevices that will also need to be scrubbed as well.

The stem needs some work. It is loose in the shank and I will need to see what the fit is like once the shank is cleaned. There is a deep tooth mark on the underside of the stem next to the button. It is not quite broken through the surface of the stem but it is deep. There are also marks on the topside of the stem in the same place though nowhere near as deep. The stem was almost clogged and will need to be cleared. The slot is tight and hard to get a pipe cleaner through easily. It will need to be opened to make cleaning the pipe a simpler procedure. Between the semi-clogged stem and the tight slot the draw is constricted. Once the repairs are made to the stem it will need to be polished.

I took a close-up photo of the rim for you to see clearly the build up on the rim. There were tars and oils deep in the grooves of the rustication on the surface of the rim. There was also a thin cake on the walls of the bowl that would need to be removed to address the heavy Latakia smell that was in the pipe. I reamed the bowl with a PipNet reamer using the smallest cutting head and working up to the third head that was the same diameter as the bowl. I then scraped the inside lightly with a sharp pen knife.

I scrubbed the inside of the shank with pipe cleaners and cotton swabs and isopropyl 99% alcohol before setting up a retort to boil alcohol through the inside of the pipe. I stuffed a cotton ball in the top of the bowl and then fit the rubber end of the test tube stopper over the stem. I place the bowl in a pipe rest and held the test tube over a candle. As the alcohol heated and boiled in the test tube it circulated into the bowl and when removed from the flame the alcohol would carry the tars and oils back to the test tube. I continued to boil the alcohol and remove it from the flame until the alcohol turned amber from the inside of the pipe.

I changed the alcohol and boiled it through the pipe again. This second time the alcohol came out clean. I kept it boiling through for about 15 minutes and then removed it from the flame. The photo below shows the relatively clean alcohol after this retort. Once I had removed the retort I cleaned out the bowl and the shank with isopropyl alcohol on cotton swabs and pipe cleaners. This time they came out relatively clean. The problem was that the pipe still smelled strongly of Latakia. The ghost was stubborn and persistent. I decided to use a cotton ball and alcohol soak to see if I could draw out some more of the oils and smell. I stuff two cotton balls into the bowl and plugged the shank. I used an ear syringe to fill the bowl with alcohol and tipped it back and forth to run the alcohol through the shank. I unplugged the shank and set the bowl in an old ice cube tray over night to draw out the oils. The next three photos were taken over a 12 hour period and show what happened with the soak.

When I removed the cotton balls and let the pipe dry out the ghost still persisted. I cleaned out the bowl and shank again, then put some white vinegar and cotton in the bowl and shank and let it sit for 3 hours. I cleaned out the shank and the ghost still remained. I was beating it but it was still present. I then filled the bowl with Kosher rock salt and then used an ear syringe to fill it with alcohol. I set it aside in the ice cube tray to let the salt do its magic.

Once I removed the salt and alcohol and cleaned out the shank and bowl a final time the ghost is pretty well exorcised. There is a faint tobacco smell but the overpowering smell is gone.

I scrubbed the top of the rim with a brass bristle tire brush and then rescrubbed it with a tooth brush and Murphy’s Oil Soap. I scrubbed it hard enough to remove the dust and grime from the crevices of the rusticated finish.

I rinsed the bowl under running water to remove the soap from the finish, being careful to not get any water in the bowl. I dried it off with a cotton cloth. The photos below show the cleaned bowl. The finish was dull and had lightened slightly.

I used a wash of brown aniline stain mixed 4 parts alcohol and one part stain to restain the bowl and shank. The next four photos show the pipe after it had been restained and buffed with Blue Diamond. I buffed it with a light touch and then rebuffed it with a shoe brush.

With the bowl finished it was time to work on the stem. I decided to start with the narrow slot and airway on the end of the stem. I used three different needle files to open it up. I started with a flat file to widen the gap on the top and the bottom edge of the slot. I needed it open enough that I could use a flat oval file to smooth out the slot and open both the top, bottom and sides of the slot. I finished with a round file to taper the edges of the slot at an angle to the airway in the stem. While this was done to a slight degree I increased the angle and also opened up the end of the airway. I used the round file to also enter from the tenon end of the stem and smooth out what appeared to be rough transitions from the airway to the slot. I finished by sanding the inside of the slot with a folded piece of 220 grit sandpaper and then finishing with a bristle pipe cleaner and a little scrubbing powder.

I still needed to clean up the end of the stem when I worked on the stem surface itself but the basic shape was finished and the slot was wide enough to easily handle a pipe cleaner. I sanded the stem with 220 grit sandpaper and also with a medium and fine grit sanding sponge to remove the tooth chatter on the top side of the stem and to clean up around the deep tooth mark on the surface of the stem. I picked out the debris from the tooth mark and then filled it with black super glue. I set the stem aside overnight to let the glue repair cure.

The next morning I sanded the repaired area with 220 grit sandpaper and then the sanding sponges to remove the excess patch and to blend it into the surface of the stem. Once the repair was smoothed out it was time to sand the stem with micromesh sanding pads. I wet sanded with 1500-2400 grit pads and rubbed it down with Obsidian Oil. Once it had dried I gave it a quick buff with White Diamond. The tooth chatter was gone on the top of the stem and the repair on the underside blended in quite well. At this stage in the sanding it still showed but would begin to disappear into the stem with further sanding with micromesh. I dry sanded the stem with 3200-4000 grit pads and then rubbed it down again with Obsidian Oil. The first photo below shows the topside of the stem. The tooth chatter is gone. The second shows the underside of the stem. The tooth mark is repaired and the repair no longer shows. The next three grits of micromesh will make the patch disappear in the shine of the stem.

I dry sanded with 6000-12,000 grit pads and then gave it a final buff with Blue Diamond. I rubbed in a final coat of Obsidian Oil and let it dry.

The next two photos show the finished stem. The repair is blended into the vulcanite and it is polished and clean.

I gave the pipe a light buff with Blue Diamond Plastic polish and then gave the stem several coats of carnauba wax. I lightly buffed the bowl with carnauba and then buffed the entire pipe with a clean flannel buff to raise the shine. Here is the finished pipe. Thanks for looking.

Restoring an Ed Burak Connoisseur Tall Stack

5 Replies

Blog by Steve Laug

The next pipe that came to my worktable was the shapely stack pictured below. It is stamped Connoisseur over N.Y.C. on the left side of the shank and then below that E. Burak in script. The majority of the stamping is very sharp. The N.Y.C. is a bit faint. There is no other stamping on the pipe or shank. The briar was natural and unstained. It had darkened slightly with age. The finish was dirty and there were a few dents and dings in the briar. The stem was badly oxidized and had several small tooth marks on the surface. It was over bent and the way it hung in the mouth would dump the ash in your lap. The rim had a tarry buildup on the back top surface. The inner and outer edges of the rim were in perfect shape. There were some small sandpits in the briar on the left side of the bowl and on the underside of the shank. The inside of the shank was dirty and black with tars and oils. The bowl inside was thickly caked with a crumbly soft cake that was flaking away in some parts of the bowl. The shank itself was interesting to me in that it looked perfectly round. Once the stem was removed the drilling of the mortise was centered but low on the shank. The drilling was perfectly aligned but the airway seemed constricted. My guess was that there were tars and oils clogging the airway in the shank and the over bent stem made the draught constricted.

Over the years I have had several Connoisseur pipes but none of them were stamped like this one. I wondered about the stamping. It was my guess that it somehow helped with dating the pipe to a particular time in Ed Burak’s pipe making career but I did not know for sure. I decided that before working on this particular pipe I would do a little research on the brand and the maker on Google. I always check Pipedia to see what they might have on a maker. In this case I was not disappointed. There as a great article on the site. The link to that is: http://pipedia.org/wiki/Burak.

On that site I found not only some history on Ed Burak and the brand but also a photo of a pipe that was the same shape as the one I was working on. I was fortunate to find it because it confirmed my earlier assessment that the stem was over bent. With the photo and a second one that I found on another site I would be able to correct the bend on the stem and open the airflow from the bowl to the button.

I also found some great information on the site regarding Ed Burak. I quote from that article below. If you should wish to read it in its entirety click on the link noted above. The article is entitled, The Art of Edward F. Burak, Dean of American Pipe Designers.
“Ed Burak is the dean of American pipe designers whose work has had a worldwide influence on the thinking and the work of contemporary pipe makers.”

“…he met and subsequently began working with Meerschaum master Paul Fisher, with whom he stayed 5 years. During that time he produced a small number of Meerschaum pipes, a few of which are still extant in collections. He also worked for Wally Frank as a pipe designer. In 1968 he bought the Connoisseur Pipe Shop, where he was able to concentrate on his own designs. Burak’s pipes have been carved by a number of well-regarded pipe makers, among them Joe Corteggione and Tony Passante. Several of his freehands are in the Museum of Modern Art in New York and have been part of a traveling exhibit of the American Craft Museum.”

“Burak’s work is best known as pipe design as fine art. He admires pays tribute to the classic English designs of the old Barlings and Comoy’s and offers a line of “Classics” which begin with these traditional values yet reflect his own interpretations.”

“Because these pipes are different, so carefully crafted, they not only please the eye, but educate it. Most pipe makers will start with an idea and work the wood toward that goal, but will change their original design to accommodate the briar. Burak does not allow the medium to modify the intent. Minor surface flaws are left on the pipes. No staining is permitted; all Connoisseurs have a natural finish, with only carnauba was added.”

“As a significant footnote, the reader should note that Ed Burak’s pipes are NOT made by Paul Perri, nor Weber, nor Jobey, as erroneously stated in Lopes’s book “Pipes: Artisans and Trademarks.” Burak prefers not to disclose the name of his current pipe carver.”

I also learned on Pipephil’s website, http://www.pipephil.eu/logos/en/about-en.html that the stamping did indeed give some information that helped in identifying the period that a particular pipe was made. There I found that one may generally separate Connoisseur pipes date of manufacture into three periods.

From late 1960’s until 1974: no stampings
From 1974 until 1981: CONNOISSEUR over N.Y.C.
From 1981 on: CONNOISSEUR over N.Y.C. and Ed Burak’s signature

The pipe I was working on was stamped like the photo below. It had the Connoisseur over N.Y.C. stamp and Ed Burak’s signature. That dated the pipe to the time period from 1981 to the time that the Connoisseur Pipe Shop in Manhattan closed in 2009 on Ed’s retirement. Included with the photo of the stamp was a picture of a tall stack pipe that looked identical to the one that I was working on. Using the photo above and this photo gave me a clear picture of what the bend of the stem was like originally. I took a photo below of the stamping on the left side of the pipe that I am working on for comparison with the one above. You can see that they have the same stamping. On the Puff.com Pipe Forums I found a thread on Connoisseur pipes that confirmed how the pipes were finished when they were originally made. http://www.puff.com/forums/vb/general-pipe-forum/299824-ed-burak-pipes-man.html. There in the latter part of a post by a member identified as Mr. Rogers was the information that I was seeking confirmation about.

“His premium pipes were like nothing I had seen before. He finished all of his pieces with only wax, no stain. He incorporated blemishes into his designs and made no attempt to hide these flaws with fillers. I frequented the CPS (Connoisseur Pipe Shop) as a high school, college, then grad school student, never really having the funds to purchase his premium pieces. As luck would have it, once I became established in my work/field, the CPS was long gone…”

Now that I had a pretty good idea of when the pipe was made and what the stamping meant, it was time to go to work cleaning up this beauty. I took a close-up photo of the bowl to show the state of the uneven broken cake that was formed on the walls of the bowl. The cake had a fuzzy appearance that bothered me. So before I cut into it with the reamer I examined it with my lens to see if it was mold. I was glad to see that it was merely dust particles. I was able to blow them out before with a blast of air before I reamed back the cake. You can also see the flaw on the back side of the rim centered between the inner and outer edge of the rim. I reamed the bowl with a PipNet reamer. I started with the smallest cutting head and worked up to a cutting head the same diameter as the original bowl. The bowl was U-shaped but narrowed slightly half way down the bowl so I had to use the second cutting head to clean out the bottom half of the bowl and smoothed out the transition between the two cutting heads with a sharp pen knife. I took the cake completely back to the bare wood so that a good, clean, solid cake could be formed.

I scrubbed the exterior of the natural briar with alcohol on cotton pads. It removed the grime, oils and ground in dirt from the finish and left the briar clean. I dropped the stem in a bath of Oxyclean. Almost as soon as it hit the water and I shook it the mixture turned amber coloured as the Oxy worked on the oxidation. I set the bath aside to let the stem soak and turned my attention to cleaning up the bowl. Before I could repair the flaw on the rim I needed to clean it up. I lightly topped the bowl on the topping board using 220 grit sandpaper. Once I had topped it lightly I washed it down with alcohol on a cotton pad to remove the sanding dust and blew out the dust in the bowl. I picked out the dust and grime in the flaw and used a drop of clear super glue and some briar dust from the topping of the bowl to fill in the flaw. Once it was hardened I sanded it with 220 grit sandpaper on the topping board and then with a medium and a fine grit sanding block to smooth out the scratches and polish the rim. The photo below shows the repair to the rim as well as the oils and tars on the cotton swabs and pipes cleaners that I used to clean out of the mortise and airway. I also wiped down the inside of the bowl with alcohol on cotton swabs to remove the dust and any remnants of the old cake. With the bowl cleaned and repaired I took the stem out of the Oxy bath. It had been soaking for about 2 hours and the oxidation was softened and brought to the surface enough that when I scrubbed stem to dry it off I was able to remove much of it.

I put the stem in the shank and used a heat gun to heat the vulcanite and reduce the angle of the bend in the stem. I took it back to the work table and took the next four photos of the new angle of the stem to see how it looked from the comfortable distance of the computer screen. I took it back and heated it again to bend it slightly more. The angle was close but I would need to adjustments to get to what I wanted for the bend in the stem.

While this photo was taken to show the stem it also gives a good picture of the repair to the rim on the pipe. It blended in very well and looks far better than the original crevice.

I sanded the stem lightly with 220 grit sandpaper paying special attention to the tooth marks and tooth chatter near the button on both the top and bottom of the stem. Once I had removed the marks and chatter I sanded it with a medium and a fine grit sanding sponge to remove the scratches.

The next four close-up photos show what the stem looked like at this point in the process of removing the oxidation and scratches.

To highlight the beautiful mixed grain on this piece of briar I rubbed it down with a light coat of olive oil and let it soak into the briar.

I sanded the stem with micromesh sanding pads – wet sanding with 1500-2400 grit pads. Once I finished with the 2400 grit pad I buffed it with White Diamond and then rubbed it down with Obsidian Oil. I dry sanded with 3200-4000 grit micromesh pads and again rubbed it down with Obsidian Oil. Once it dried I lightly buffed it again with White Diamond to give it a deeper polish. Then I continued sanding it with 6000-12,000 grit micromesh sanding pads.

I gave it a final coat of the oil and took the pipe to the buffer and buffed it with Blue Diamond Plastic Polish.

I buffed the whole pipe with Blue Diamond and gave it multiple coats of carnauba wax to protect the finish and the stem. I finished buffing it with a clean, soft flannel buff and no buffing compounds to raise the shine on the finish and the stem. The finished pipe is shown below. Thanks for looking.

What are the options for repairing a damaged stem?

8 Replies

Blog by Steve Laug

Over the years that I have been working on pipe restoration I have found that when working on badly damaged stems I have 4 basic choices on how to deal with the damage. They are stated in the form of a simple list below but each one will have to be detailed out to understand the implications of the choice.
1. Cut it off
2. Build it up
3. Splice it
4. Replace it

Choice #1 – Cut it off

This sounds pretty brutal but it really is a pretty easy repair to work on the chewed stem. I generally see how far back I have to go to get enough stem material on the top and bottom of the stem to shape a new button. Once I have a pretty clear idea of that I put a piece of cellophane tape on the stem to get an idea of how it will look with that bit of stem removed. Sometimes the new stem length just does not work. If it is too short it is awkward. If not then it can be reworked and still look acceptable. I have even cut back badly broken billiard stems and crafted a Lovat shaped pipe that looked really good. The decision is yours and cannot be reversed without making a new stem for the pipe.

The process is quite simple. Once I have marked the part of the stem I plan to remove I use a Dremel with a sanding drum to remove the damaged portion. It works quite quickly. The only caution is to keep the line straight as you are removing the broken part of the stem. This line is not only the horizontal one across the surface of the stem but also the vertical one looking at the pipe from the end. Others use a coping saw or hacksaw to remove the broken area. I prefer a Dremel. With the end removed the stem is ready for reshaping. I use needle files to cut a new button on the stem. I do that by filing a straight line across the top and bottom of the stem making sure that they align.

Once the new button line is in place I use a flat needle file to file back the slope of the stem to the button line. I am careful not to go to deep but judge depth by the amount of material above the opening in the stem end. Once I have the slope set and the button more defined I use the flat needle file to clean up and define the edge of the button. I want a good sharp edge on the inside of the button to catch behind the teeth. I use 220 grit sandpaper to clean up the slope and smooth out the file marks.

When I get the stem shaped the way I want it I then move on to the shaping of the button. I like a button that is shaped like an oval that tapers outward to the edges on both sides. I sand and file and file and sand to shape it. When I have the shape correct I also slope the button backward toward the airway on the stem end. I generally am working the button to look as much as possible like the one that was originally on the stem. I use pictures of the stem from the internet or from the camera that I took to get the look just right. After the button is shaped I work on the airway in the end of the button. I want it to be a slot. I use the needle files to open the airway. I flair it from the opening like a Y. The idea is to create an opening that is funnel shaped. I start with a flat file and work toward a round and an oval needle file I shape the ends of the slot to match the shape of the button as much as possible. When I finally have the slot open I fold a piece of sandpaper and work on the inside of the slot to smooth out the file marks.

I finish by sanding the stem with micromesh sanding pads and polishing it to give it a shine. Here are some photos of the finished stem.

Choice #2 – Build it up

I have used this method quite a bit with variations. I have used it repair bite marks and bite throughs on stem. The basic procedure is to clean up the affected area on the stem with alcohol and sandpaper to prepare it for the buildup. I leave the area slightly roughened to give the repair something to grab on to. Once all loose debris, sanding dust and oxidation is removed you are ready to begin the patch. The stem I am using to illustrate the process had holes on both sides of the stem and both were large. Alongside both sides there were also many tooth dents that needed to be addressed as well. In this case those dents would provide a strong base for what would be a large patch.

I grease a piece of folded paper or a nail file with Vaseline and insert it into the slot on the stem. I want to have a slick base for the glue to sit against but not fasten to. I also do not want to close off the airway and this method has worked well for me for many years.

With the folded paper inserted it is time to begin to build up the repair. I use medium viscosity black super glue that I get from Stewart MacDonald online. I build up the edges of the repair first. Some folks will use an accelerator at this point to speed up the process. I have also done so but find that the glue is more brittle and I have had patches fail after using it. So I have learned to “patiently” wait for the glue to harden. Others mix in fine charcoal powder or grit with the superglue and feel that it gives a stronger patch. I have done that as well but did not choose to use that on this stem repair.

As the first layer of glue dried I continued to build the patch inward to the middle and thicken it as well. The process took several days and included at least four layers of glue.

Once the last layer of the patch was finished I set the pipe aside to cure for several days. When it was dry I sanded it with 180 grit sandpaper and then 220 grit sandpaper to level out the patch and the surrounding stem.

I used needle files to sharpen and define the edge of the button. I sanded it with a medium and a fine grit sanding sponge. The patches show up still in the surface of the stem as a slightly different colour but once the stem is sanded with micromesh they begin to disappear.

The finished stem looks like new.

Choice #3 – Splice it

On the blog, Jacek Rochacki has written of splicing a repair and reshaping the stem. I am inserting his procedure at this point to explain the choice he uses.
Instead of cutting/removing the damaged part and carving the lip/button of what is left, I would proceed in different way. Keeping in mind my wish of keeping original dimension, proportions, form, I would try to reconstruct damaged stem/mouthpiece as following:

By using sharp cutting tools – engravers/burins, scrapers or in case of better equipped “workshop corner” – cutters, like those used by jewelers for stone settings, or even a sharp pocket knife, a frame saw and needle files I would work on the damaged area making it a proper shape a piece of the same material carved that I will later shape/carve to fit what is missing. The words “making it of proper shape”, may be a subject for another longer text. But as sort of inspiration may be the different ways dentists use to “elaborate” holes in teeth so that the filling will be kept securely in place. In a stem the situation is easier as we have good binding glues and are binding together the same kind of materials – vulcanite/ebonite to vulcanite/ebonite.

When the newly carved material is fixed into the missing area with glue, I work with files and drill bits to achieve desired missing shape. Then I proceed with finishing techniques. Let us look at the pictures:

Others have actually cut off the broken portion of the stem after matching it to a similar style and shaped stem. The also cut off the replacement stem so that the undamaged areas match perfectly. A small stainless steel tube can be used to join the two pieces of stem together and black superglue can be used to hold it together and to fill in the joint of the two stems. Once the glue has cured then the repair can be sanded and blended together so that it does not show at all.

Choice #4 – Replace it

The fourth option is to fit a replacement stem on the pipe or make one from vulcanite or Lucite rod stock. I do not have a lathe so I usually use precast stems and do a lot of shaping and fitting and improvements on the blank. The photos below show a new stem that I fit to a Lovat pipe for a friend. I used an old saddle stem that I had here so I did not need to use a precast one. This one just needed adjustment and fiddling to make it work well.
The original stem had a large bite out of the end of it the underside next to the button. I choose a stem that is similar in shape and style that was the same length. It had a slightly larger saddle portion on the stem but I liked the look of it and figured it would work. I turned the tenon down slightly to make for a snug fit in the mortise. In this case I sanded the stem down to remove the oxidation from the surface and also to remove the slight tooth marks and tooth chatter that was there.

After sanding with the 220 grit sandpaper I used a medium and a fine grit sanding sponge to clean up the stem further and remove scratches.

I sand the finished stem with micromesh sanding pads to polish it. After sanding with the 12000 grit pads I buffed it with Blue Diamond Plastic Polish and then with carnauba wax and a soft flannel buffing pad. The finished stem is shown below.

Refurbishing a 1978 Dunhill Root Briar 41041 Bulldog

Blog by Steve Laug

This is another pipe that came to my work table. It is a beautifully shaped Dunhill Bulldog. It is stamped 41041 and Dunhill over Root Briar on the left side of the shank. The right side bears the made in England stamping with the date number that puts it at 1978. The bowl was in excellent shape and had been recently reamed and cleaned. The finished was dull but very clean. There were no issues with the briar. The stem was also in great shape other than being heavily oxidized on the top sides. There was a small tooth mark on the top side of the stem next to the button as well. What made this one interesting to me was the issue that I often see with diamond shank pipes. The sides all looked the same but were not when measured. The top left was slightly bigger than the top right and so forth. It was not an issue as I did not need to replace the stem but it was just an interesting tidbit and one thing I always look for when working on diamond shank pipes. The next series of four photos show how the pipe looked when I brought it to my work table.

I took two close-up photos of the stem to show the oxidation and the slight tooth mark on the topside near the button. The underside of the stem was not as badly oxidized but had slight oxidation.

I mixed up a batch of Oxyclean and put the stem in it to soak overnight.

While the stem soaked I decided to clean out the shank and airway. I used isopropyl alcohol, cotton swabs and pipe cleaners to remove the tars and oils in the shank. I have found that even when I buy a “refurbished” pipe on eBay I do this and am always surprised at the grime and oils that come out of the “clean” shank. I did not want to use the retort on this one as it was not terribly dirty and had been subjected to a pretty good cleaning before it came to me. In the morning when I took it out of the bath and dried it off much of the surface oxidation was gone and the mix had raised some more oxidation.

I put a plastic washer on the tenon and put the tenon in the shank so that I could clean up the edges/shoulders of the stem without rounding them. I sanded it with a medium and a fine grit sanding sponge to start with and worked on the oxidation.

I wet sanded the stem with 1400-2400 grit micromesh sanding pads. I worked on the scratches as well as the oxidation on the stem. I “painted” over the surface of the stem with flame from a BIC lighter to burn off some of the surface oxidation and then wiped it down with Obsidian Oil. The photos below show the stem after that process.

I went back over the stem with the 1500-2400 grit micromesh sanding pads until the surface was freer of oxidation. I then wet sanded it with 3200-4000 grit pads and the shine began to show up.

I buffed the stem with red Tripoli and White Diamond before finishing with 6000-12,000 grit micromesh sanding pads. When I finished with the pads I rubbed down the stem with Obsidian Oil and let it soak in.

Once the oil had soaked into the stem I buffed the bowl and stem with Blue Diamond plastic polish being careful around the stamping on the shank. I gave the bowl and the stem multiple coats of carnauba wax and then buffed it with a clean, soft flannel buffing pad to raise the shine and give it that like new look. The finished pipe can be seen in the photos below. It is ready for the next pipeman to load up his favourite bowl and have a smoke.
