Finding a Hidden Gem Underneath all the Grit and Grime


I went to work on the third pipe down in the far right column. It was one that I almost bypassed because of the shape it was in, but decided to take a chance and see what was underneath all of the mess. The stamping was long ago worn away by buffing. It had originally had a ferrule on the shank and that was missing. The bowl was badly caked and it was out of round from overzealous reaming. The finish was shot with thick black grime impregnated into the bowl finish all the way around. Underneath there appeared to be some nice grain. The missing ferrule left behind remnants of the glue that had held it in place. In the shank where the ferrule was missing were several fills – the only ones in the pipe. The size of the pipe is about a group 2 – kind of the classic size of an older billiard. The stem was missing so it would need to have one made to fit.

The next series of photos shows the build up on the outside of the bowl. Not only was it badly caked it also was covered with a grey/black grime that would be challenging.

I used acetone and cotton pads to remove the external grime on the bowl (Photos 1 – 2 below). There was actually some nice grain underneath all the grime. I reamed the bowl with a PipNet reamer starting with the smallest cutting head and working my way up to the largest that would fit the bowl. I wanted to ream it back to bare wood so that I could work on the damaged inner rim (Photo 3 below). I topped the bowl to remove the damage to the top of the rim and clean up the outer edges of the rim. I used my normal method of a piece of sandpaper on a flat surface and pushing the bowl into the sandpaper and rotating it to remove the damaged briar (Photo 4 – 5). I also push a nickel band onto the shank part way. I would later need to heat it to get a pressure fit deep on the shank. This band would both strengthen the thin walls of the mortise at the end and also cover the only fills present on the pipe.

I used a Dremel with a sanding drum to work on the roundness of the bowl. I worked to even out the distance between the inner edge of the rim and the outer edge. Once this was completed I used sandpaper to smooth out the edge and give it a slight bevel (Photo 1). I wiped down the bowl and rim with acetone on a cotton pad to clean off the last of the dust and grime from the reaming and sanding (Photos 2 – 3).

I set up the heat gun and turned it to the high setting. I held the band over the heat and rotated it to evenly heat the entire band (Photo 1). Once it was heated (just a few minutes) I then took it to the work table and pressed the band in place on a metal plate I use for setting the bands. Sometimes this takes several trips between the heat and the plate but this time one trip was all it took and the band was set (Photos 2 – 3).

I used a PIMO tenon turning tool to turn the tenon to fit the mortise. I generally turn it until it is close and then finish the fit by hand with sandpaper (Photo 1). After sanding the stem fit quite well in terms of the tenon. It was snug and flush against the shank – no light showing through (Photos 2 -3). I used the Dremel with a sanding drum to remove the excess vulcanite on the stem and to shape it to match the diameter of the shank. I sand carefully with the sanding drum to bring it as close as possible to the size I want. You have to be careful and steady so that you do not nick the shank or the band while doing this. The finishing fit is done by hand with files and sandpaper (Photos 4 – 5).

The next series of seven photos show the shaping process. I begin with a medium grit emery paper and sand out the scratches left behind by the Dremel. I shape the stem with this paper to the point where the flow and fit of the stem is what I am looking for (Photos 1 – 2). I then move on to 220 grit sandpaper and continue to remove the scratches and shape the stem (Photos 3 – 4). It then finish this shaping with a fine grit sanding sponge and polish out more of the scratches. Each grit of paper brings the stem closer to the finished shape (Photos 5 – 7).

I apologize for the graininess of the next two photos but they show the bowl after I had stained it. I used a dark brown aniline stain thinned with one part alcohol. I wanted a rich reddish brown colour on this old timer so I thinned the stain to match the colour I wanted. I applied it to the bowl and rim, flamed it, reapplied it and flamed it again.

I worked on the stem with micromesh sanding pads. I also sanded the nickel band to bring out a polish to it as well. The next series of seven photos shows the progressive shine that comes to the stem with each successive grit of micromesh from 1500-12,000 grit. I wet sanded with the 1500-2400 grit and then dry sanded with the remaining grits.

I sanded the bowl with the higher grits of micromesh and then buffed the pipe with White Diamond to give the entirety a rich shine. I applied several coats of carnauba wax and buffed it with a soft flannel buff. The stain really highlights some of the beautiful grain on this pipe. I am glad I took the risk to bring this one back to life.

Restemming and Reclaiming an Older, Unsmoked GFB Briar Calabash


Blog by Steve Laug

I bought three unsmoked pipe bowls from the same seller on EBay. One of them was a GFB calabash. With the first of this brand I bought a while back I did some digging on the web and found very little information. So this time I did a bit more searching and I was able to get some information on the brand. Many of the links I found through Google took me to others who were looking for information on the brand. I came across one that gave the information that the GFB brand was an older French Trademark and that it came from Saint Claude, France. With that information I did a more focused search for GFB French Briar Pipes and came across a post that said GFB stood for Great French Briar – that seemed a little farfetched to me so I continued to look and finally came across the following advertisement from a Sears Catalogue. It shows a full page of GFB pipes and the header says GENUINE FRENCH BRIAR. That made much more sense to me and the pipes in the catalogue matched the ones that I have in my collection and the ones that I have seen. For me that gives a better picture into the meaning of the brand letters.

Genuine-French-Briar-Pipes-On-Parade

Armed with this new information I went to work on the GFB Calabash pipe bowl that I purchased. The bowl itself was in astonishingly great shape for being over 100 years old. The pipe was unsmoked – new condition. The bowl was dusty but raw briar. The shank was clean and also pristine. This was an unsmoked – new old stock pipe bowl. The silver band was very tarnished and loose. There was no stem to be found. I wrote to the seller and asked what had happened to the stems for this old timer and two others I purchased from them. I did not receive an answer. The first four photos below are the seller’s photos as the pipe appeared on EBay. The first two are out of focus but give an idea of the bowl shape. The last two give close up photos of the stamping and the clean bowl. It was pretty hard to know the size of the pipe from their information. But it looked to be of similar age as an older 1912 BBB Calabash I have so I put in a bid and won.

GFB2

The right side of the shank is stamped America and the left side is stamped Premier. The band has three stars *** over the GFB in an oval and under that is the Sterling stamp. The stamping led me to assume incorrectly that this was an older American made pipe. I was wrong. The stamping America obviously is the name of the pipe.

I looked through my box of old stems to find one that would be not just a proper fit but of an age that was appropriate to this old pipe. I found one that did not have a tenon, it had either broken or fallen out somewhere along its journey. I have a bag of Delrin threaded tenons that I use regularly for replacing broken tenons. I chose the smallest one as it would fit the mortise with a little bit of work. The stem was oxidized but in good shape with no tooth marks or dents. The button was a slight slot and the stem was quite narrow at the button end. It would look perfect on the pipe once I had the tenon replaced.

I drilled out the stem so that the threaded tenon would fit into it. I used a tap to thread the stem. The first photo below shows the drilled and tapped stem ready to receive the new tenon. I coated the threads with some black super glue and threaded it into the stem (second photo). The third and fourth photos below shows the tenon screwed into place. The tenon is now repaired. I needed to remove some of the Delrin to reduce the diameter of the tenon to get a good fit on the shank. I used my Pimo Tenon turner to do this. It was a little tricky in that the stem was bent but I proceeded slowly to turn it down until it was close. I finished reducing it by hand until it fit snugly in the mortise.

Once the stem fit snugly in the shank I needed to reduce the diameter of the stem in order to get a good match with the band on the shank. I sanded it with medium grit emery paper to bring it down to size. The next two photos show the stem in place. At this point the band had not been glued into place. It was still loose, so I removed the stem and used Weldbond white carpenters glue (which is non-toxic) to glue the band in place. I cleaned up the old glue lines on the shank with micromesh sanding pads.

The next four photos show the silver band after it had been glued in place and cleaned and polished with some Hagerty Tarnish Preventive Silver Polish. I have used this bottle for years and it works extremely well. I purchased it at a jewelry shop along with a polishing cloth that I used on the band as well. Once the band was polished the hallmarks were very visible. I have described the stamping on the band above. After shining they stood out clearly. I am not able to ascertain a date from the stamping as there are no date stamps. I also polished the bowl with a quick buff of White Diamond on the buffer and then I gave it multiple coats of carnauba wax.

With the bowl and band finished it was time to work on the stem. I sanded it with 220 and 340 grit sandpaper followed by sanding with a medium grit sanding sponge and then a fine grit sanding sponge. This series of sandpapers and sanding sponges has worked well for me in removing the scratches left by the emery paper as well as the remaining oxidation on the stem. I then sanded the stem with micromesh sanding pads from 1500-12,000 grit to bring out the sheen on the stem and polish it. Between the 4000 and the 6000 grit I polished the stem with Maguiar’s Scratch X2.0 plastic polish. I finished with the last grits of micromesh sanding pads. The next series of six photos show the progressive shine on the stem with the various grits of micromesh.

I buffed the stem and bowl with White Diamond and then gave the pipe several coats of carnauba wax. The finished pipe is pictured below in the last series of four photos. It is amazing that this old pipe has existed this long since it was made and has not been smoked. That will change soon!

1918 J.K.L.K.Dublin Restemmed and Brought Back to Life


I saw this old stummel on EBay and was interested in giving it a refurbishment. It did not have a stem and when it arrived it was in worse shape than the seller had led me to believe. The bowl was filled with a hardened burned tobacco and also a half a bowl under that of unburned dried and hardened tobacco. The rim was very badly damaged and the cake was very thick. It was thicker about half way down the bowl and funneled down to the bottom of the bowl making the bowl appear to be conical. I knew from examining it that it was not a conical bowl so the cake would have to go. The silver band was twisted over to the right and was upside down. The stamping on the bowl was non-existent but the band was stamped J.K.L.K. and next to it were the hallmarks – a lion (signifying that the band was sterling silver), an anchor (signifying that it was made in Birmingham, England) and in the center of the threesome was the letter “t” in a boxlike shield with the corners trimmed (signifying the date of the pipe as 1918). I use a website that gives the information on hallmarks http://www.silvercollection.it/englishsilverhallmarks.html . The finish on the bowl was shot with darkening spots and worn spots. The grain underneath actually appeared to be quite nice. It looked like it would clean up very well to me. The first three pictures below show the state of the bowl when it arrived in the mail.

ImageImageImage

I took my dental pick and cleaned out the hardened tobacco, both burned and unburned. I collected it on a piece of paper to show the amount of material left in the bowl. It is always interesting to me to think about what had happened in the life of the original smoker to make him pause mid-bowl and stop smoking, set aside his pipe and not come back to it. I also wondered what happened to the stem on this pipe as it seemed that somehow it had been separated from the bowl and was nowhere to be found. I reamed the pipe with my PipNet reamer and dumped the carbon material on the paper as well. The next two pictures show the cleaning of the bowl and removal of the dottle and the cake.

ImageImage

I then set up my heat gun to heat and loosen the band in order to turn it to the correct position on the shank. I heated it using the lowest setting on the gun. I used a cotton cloth to try to turn the band several times before the heat loosened the glue and allowed me to turn it. Once it was loose I removed the band and cleaned off the old glue and the surface of the shank with an alcohol damp cloth. Once it was clean and dry I used some wood glue and spread it over the surface and then pressure fit the band in place and wiped off the excess glue. I used turned the band so that the letters and hallmarks were right side up and straight on the right side of the shank. The next three pictures show the heating and setting of the band as well as the finished set of the band.

ImageImageImage

I then looked through my can of used stems that I have scavenged and purchased until I found one that had the same diameter as the shank and band. I knew that I would have to work on the diameter of the tenon to make it fit the shank. I sanded the tenon until it fit well in the shank. I also needed to use a drill bit to smooth out the interior of the shank. I hand turned a drill bit into the shank until it was the same depth as the tenon and was smooth on the inside. I then used a slightly larger drill bit to set the countersink on the shank so that the stem would fit tightly against the shank. The next four photos show the process of fitting the stem to the shank.

ImageImageImageImage

At this point I topped the bowl rim to smooth out the surface and remove the chewed up surface and the dents and roughness. I used my board and a piece of emery cloth first. I turned the bowl top in a counter clockwise direction with the rim flat against the board and paper. I turned it on the emery cloth and repeatedly checked to see if I removed the damaged surface. I have found that regular checking keeps me from going too far with the topping process. The next four photos show the topping process. As I topped the bowl and cleaned the surface of the bowl exterior, a fairly large crack appeared in the side of the bowl and also on the top of the rim. It is visible in several of the photos at the 7 o’clock position on the bowl surface. It would need some work to repair it and a decision had to be made whether to do so.

ImageImageImageImage

Once it was sanded I wiped the bowl down with some more acetone on a cotton pad to remove the dust from the sanding. I decided to take the time to work on the crack and see if I could repair it with briar dust and superglue. I began by wiping down the bowl with a cotton pad and some acetone. Once the surface was clean I used my dental pick to clean out the crack. It did not seem to go all the way through to the inside of the bowl and as I cleaned it the depth of the crack became very evident. The first three photos below show the surface cleaned and ready to repair. The next two photos show the repairs that have been made with the briar dust and the superglue. I tapped briar dust into the crack first with my dental pick and then dripped the super glue on the rim and the bowl side. The glue on the rim ran and made a large spot of glue that would need to be sanded to clean up the spillage.

ImageImageImageImageImage

I sanded the rim by once again placing a piece of sandpaper on my flat board and sanded the bowl top like I did when I topped it. I used 320 grit sandpaper for the topping cleanup and also used the same grit sandpaper to sand the outside of the bowl. I sanded it again with 400 and 600 grit wet dry sandpaper and water to finish removing the excess glue and preparing the surface for a restaining. The next series of six photos show the repair after it has been sanded and wiped clean. The crack on the side of the bowl has all but disappeared with the briar dust/superglue repair. The one on the top of the rim also was smooth and once it was stained would also be virtually invisible.

ImageImageImageImageImageImage

I sanded the bowl with micromesh pads 1500-4000 grits and then wiped the bowl down a final time with some acetone on a soft cotton pad to prepare it for staining. I decided to use some dark brown aniline stain that I had thinned down 2:1 with isopropyl alcohol. I applied the stain with a wool dauber that came with the stain and then flamed it to set the stain. I reapplied the stain, flamed it a second time and then reapplied the stain a third time with several applications to the rim of the bowl. Each time I flamed it and set it. Once finished I took it to the buffer and buffed the bowl with red Tripoli and then White Diamond to polish it and see the finished look of the pipe to this point. The next three photos show the progress of the staining from first application to the resulting look after buffing with the White Diamond. After buffing the bowl I took it back to the work table and wiped the bowl down with some isopropyl alcohol on a cotton pad to lighten the stain some more as I wanted to make the grain more visible. I rebuffed the pipe with White Diamond and the last three photos below show the pipe after the final buffing.

ImageImageImageImageImage

At that point in the process I went to work on the stem. I sanded the stem with medium grit foam back sanding pad to remove the oxidation. I used a Bic lighter and ran it over the surface of the stem to remove the oxidation on the surface. Once that was finished I sanded the stem with 320 grit sandpaper to remove the scratches and the marks in the stem. I also worked on the taper as there were some tooth dents in the surface of the stem that had changed the flow of the taper in front of the button. Once I had removed the scratches with the sandpaper I then used the micromesh sanding pads. I wet sanded with 1500, 1800 and 2400 grit micromesh and then scrubbed the surface with the Maguiar’s Scratch X2.0. I wiped it off with a cotton pad and then dry sanded the stem with 3200, 3600 and 4000 grit micromesh pads. I then scrubbed it a second time with the Maguiar’s and then gave the stem a coat of Obsidian Oil. Once it was dry I sanded it with 6000, 8000 and 12,000 grit micromesh pads.  I then coated the stem with another coat of Obsidian Oil and then several coats of carnauba wax.

ImageImageImage

I then took the pipe to the buffer and buffed it with White Diamond before coating the entire pipe with carnauba wax. I gave it multiple coats of wax and then buffed it with a clean soft flannel buffing pad. I also polished the silver band with a jeweler’s cloth to remove any remaining tarnish and polish the silver. The four photos below show the finished pipe. It is ready to smoke and enjoy in all of its renewed life.
