My Process for Cutting off and Reshaping Broken Stems

Blog by Steve Laug

It seems like lately I have had a few of these pipes with broken stems. I have gotten several emails through the blog asking for more information about how I go about cutting back a stem and reshaping it. Since I just finished working on the Yves St. Claude pipe where I did cut back the stem and reshape the button I thought I would use it as an example of the process. I figured that this provided the perfect opportunity to spell out more of the details that I hinted at in the full blog on the restoration of the pipe. The pictures below will show the progress from broken stem to a short saddle stem. It is only one of the methods for addressing a broken stem. Stem splicing and stem replacement are also possible solution. Soon I hope to have another blog on stem splicing but until then have a look at the piece by Jacek Rochacki where he demonstrates his method. https://rebornpipes.com/2014/02/28/some-remarks-on-dealing-with-damaged-stems-of-smoking-pipes-by-jacek-a-rochacki/

1. Before I cut off anything on a stem I spend quite a bit of time examining the broken stem. For me that means checking out the thickness of the stem material above and below the airway in the stem. There needs to be enough thickness that I can shape a button on the cut off portion. I check out the stability of the vulcanite to see if it crumbling or if the break is clean. Sometimes you need to cut quite a ways back into the stem to get either the correct thickness or stability to reform a button. I always try to imagine what the pipe will look like with a shorter stem. To help me see it I have devised a simple method. I clasp it between my thumb and finger making a straight line across the stem. Using my finger and thumb I can slide the stem as far as I want between the fingers and get a good picture of what the pipe will look like with a shorter stem. If all of these steps are passed then I get ready to cut off the broken portion.

This stem passed all the tests. The break not straight across the stem but actually was slightly diagonal. It was a very clean break with no crumbling material. The airway appears to be close to the surface on the top side of the stem but because of the angle of the break there was sufficient material there for me to cut and shape a button. I was ready to cut of this stem.

2. I marked the stem with a pencil to delineate how far I planned on cutting the stem. I use a Dremel with a sanding drum to cut off the broken portion of the stem to the point of my line. Others use coping saws or hacksaws to remove the material. Choose whatever tool you are comfortable with to do the work. For me I hold the Dremel in my right hand and the stem in my left. I keep the stem stationary while cutting but frequently rotate it in my hand to keep the edges straight. I am always conservative in the first cut only taking off what looks to be necessary. I want a solid surface to work on with the button. Once I have the cut finished I use the drum to slightly round the corners of the line. In the end I wanted to have a slight crown on the finished button so I plan for that at this point. In the two photos below you can see the slightly bow in the cut off. The cut off edge is vertical to the surface of the stem forming a 90 degree angle.

3. When the cut off is finished I take time to look at the profile of the stem. In this case the stem was quite thick. I was going to need to shave off the surface and thin the stem down but I would not do that until I had cut the button and roughed in the shape. Looking at it I could also see that I would need to flatten the stem near the new button as it had a definite rounding that would make it uncomfortable in the mouth.

4. The first tools that I use are a knife shaped needle file that has a thin edge like a blade and squared edge for the initial cuts and a folded piece of 220 grit sandpaper to clean up the newly cut edge. 5. I cut the edge with the straight edge of the file. I eyeball the line to make sure it aligns on both sides of the stem. This is a bit tricky at first but I rotate the stem to and angle where I can see both sides at once and begin the second cut. At this point in the process I am not finishing the cut but only drawing the line with the file. With the line cut and the button edge defined there is a lot of finishing work that needs to be done but you can get a clear picture of what the button will look like.

6. I use the knife edge of the file to shave the surface of the stem on the top and bottom sides. Be careful not to gouge the surface but smoothly shave it. I hold the blade at slight angle against the surface of the stem and carve toward the button. I have the stem on the table and work the blade away from myself sometimes and other times I have it in hand with the new button against the heel of my palm and work the blade toward the button. I work the blade until I have defined the line of the button and flattened the crown on the surface of the stem. Remember this is all initial carving. It will be cleaned up and smoothed out with the sandpaper and other files.

7. When I have the material in front of the button cut away and thinned down I sand it with the folded 220 grit sandpaper to get an idea of how it looks and of how much more I will need to remove from the crown on both sides of the stem. In the case of this stem I have enough material removed. I still need to shape the button and clean up the edges of the sharp edge. The top and bottom surface of the button still need to be shaped and sanded but the overall look is good to go.

8. With the rough shape finished I cut the slot in the end of the button and flare the airway. The first photo below shows the way the airway looked once I cut of the stem. You can see that there is plenty of material above and below the airway. I started the process by sanding the face of the button on my topping board and sandpaper. It is important to make sure that stem is absolutely vertical and does not tilt either way when doing this. You want to make a smooth face to work on the slot. 9. I use several different needle files to open the slot. The first file I use is a flattened oval file shown in the photo below. I work it against the right and left edges of the airway to open the slot. I don’t worry about the finished look at this point but am concerned to rough it in with the file. The flattened oval does the initial shaping work. I like a slot that is oval and tapers to a point on each side. I also work the file into the airway to taper the internals into a Y shaped funnel ending at the airway. 10. I work the top and bottom edges with the second file – an oval blade that is not flattened and almost round. I use it to work the internals into more of a smooth Y and then open the top and bottom of the slot. I follow this with a round needle file that has a thin point to clean up the opening and shape it. The photo below shows the slot after I have used all three files. 11. I fold a piece of sandpaper into a rectangle that I can fit into the slot. I work it in the slot to sand the internals and remove the file marks. I sand the face of the button to remove file marks and also sand the slot to refine the shape of oval. 12. The next photo shows the slot after I have worked it with the sandpaper. The internals are clean and smooth. I then use a pipe cleaner and isopropyl alcohol to remove any dust from the inside of the airway. The face of the stem still shows some light scratching that will be taken care of with wet sanding using micromesh sanding pads. However, you can see the new shape of the slot and how it sits on the button. That portion of the reshaping of the new button is finished and all that remains is to sand and polish the stem with the micromesh and the buffer. 13. I sanded the stem – all surfaces including the button face with a medium and a fine grit sanding sponge to remove the scratches left behind by the 220 grit sandpaper. I worked on giving the surface of the button a slight bevel downward toward the slot. I personally like a gentle slope so I don’t overdo it with the sanding.

14. With the scratches removed the stem is ready for polishing. I used micromesh sanding pads to do this work. Others use high grit wet dry sandpapers or micromesh papers. I like the way the pads fit in my fingers and how I can push the edge up against the slot to work that angle. I wet sand with 1500-2400 grit pads – wetting the surface of the stem and then sanding with the pads. I wipe it off regularly to remove the grime and check on the smoothness of the surface. I sand with each of the three grits until the particular grit no longer takes off any of the vulcanite. Once I finish with the three pads I rub the stem down with Obsidian Oil as I find it highlights the remaining scratches and also helps the micromesh to bite into the surface of the stem. I have used olive oil to do the same thing, applying it sparingly with a fold piece of cloth or paper towel. At times I have applied the oil between each of these three grits – essentially replacing the water with the oil. It works very well. 15. I dry sand (no oil or water) with the remaining grits of micromesh. I sand with 3200-4000 grit pads and then rub the stem down with oil again for the same reasons as above. I then either go back to the 1500-2400 grit pads to rework areas of concern or move on to sanding with the 6000-12,000 grit pads.

16. I buff the stem with White Diamond at this point in my process. If you do not have a buffer you can buff with a plastic polish on a cotton pad or cloth. The idea is to remove any of the remaining scratches (micro scratches really at this point) and give the vulcanite a high sheen. When I finish buffing I give the stem multiple coats of carnauba wax. When I did not have my buffer I used Kiwi neutral shoe wax which has carnauba in it and hand buffed the stem with a shoe brush. Sometimes I revert to using the shoe brush even now. Especially when buffing areas around stamping and logos.

17. The finished stem is shown below. The button looks like it has always been there. I like giving it a look that fits the age of the pipe. I don’t want it looking like a brand new button that has been tacked onto an old pipe. Rather I want it to look as if it has been there for the life of the pipe and has seen some smoothing from use. You can be the judge if I have achieved that but at least that is the aim. You can also decide how you want the buttons that you shape to look. Don’t be afraid to experiment and add your own steps or modify these so that they work for you. The end result is really all we are interested in anyway and the methods for getting there are many.

A GBD “Dublinish” Poker Brought Back to Life

Blog by Steve Laug

The fourth pipe I have refurbished from the lot I just picked up is an oval shanked “Dublinish” Poker that has a GBD on the brass stem roundel. It is stamped on top of the shank with GBD in an oval over New Standard in script. On the underside of the shank it is stamped London England over 9558. I looked up the shape number on the GBD shape site and was unable to find a listing for a pipe of this shape. I looked other places on the web and did not find this shape either listed or pictured. It is certainly not a shape that I have seen for the years that I have been working on pipes and collecting GBD pipes.

The picture below shows the state of the bowl when I brought it to the work table. It had a thick and crumbly carbon cake and carbon and tar build up on the concave surface of the rim. The front of the outer edge had burn marks from repeated lighting. The GBD roundel on the stem was badly oxidized and looked to be corroded. The stem was badly oxidized and on the bottom had a large hole where the previous owner had bitten through the stem.

The picture below shows the size of the bite through and gives a pretty clear picture why I chose not to patch the stem but rather to cut the bite through off and rework the stem and button.

I cut off the end of the stem with a Dremel and sanding drum attachment. I cut it back to the place behind the bite mark that was solid and undamaged. The next four photos show the pipe with the damaged portion of the stem removed and a straight cut made across the end of the stem.

I took it back to the work table and reamed the bowl with a PipNet reamer. I used three of the cutting heads from the smallest up to remove the cake and clear out the debris in the bowl. I wanted to remove the cake to assess the soundness of the rim and the bowl of the pipe. I scrubbed the rim down with saliva and cotton pads. It took a lot of elbow grease to finally get the rim clean of the buildup and tars. In the photo below the burn mark on the front of the bowl is visible.

I used files, a wood rasp and needle files to cut the line on the button across the top and the bottom of the stem. I trimmed the thickness of the stem tapering toward the shank with the needle files. I wanted to thin down the stem and taper is more smoothly into the new button making for an even transition from the saddle to the edge of the button.

I used the needle files to open the end of the button and shape it into and oval and a funnel into the airway. I wanted a good open airway that would easily take a pipe cleaner.

After working with the files I sanded the stem with 220 grit sandpaper to remove the oxidation and to continue to shape the stem into a smooth taper from the saddle to the button.

I sanded the end of the button to angle it back toward the slot and to smooth it out and shape it. I also used the needle files to clean up the straight edge of the button.

Once I had the taper and the angles correct I sanded the stem with a medium grit sanding sponge to remove the scratches from the sandpaper.

When the stem was finished in terms of shaping I moved on to work on the bowl. I wanted to stain the rim and the edges of the bowl where the burn marks were. I used a red mahogany Minwax stain and rubbed it into the rim and gave the entire pipe a stain coat. Once I had wiped that off with a clean towel I gave it a second coat of medium walnut stain to blend it in even more with the rest of the bowl. I buffed it with White Diamond to polish it and give it a shine.

I sanded the stem with my regular regimen of micromesh sanding pads – wet sanding with the 1500-2400 grit pads and dry sanding with the 3200-12,000 grit pads. I rubbed in a coat of Obsidian Oil and when it had dried took the stem to the buffer and buffed it with White Diamond to give it a shine.

I buffed the entire pipe with White Diamond and then multiple coats of carnauba wax. I finished by buffing the bowl and stem with a clean buff with soft flannel to bring out a high shine. The finished pipe is shown below in the pictures. The shortened stem came out looking very good and the reduced length does not detract from the look of the pipe as a whole.

When I saw it I thought it was a Sasieni one dot billiard

I came across this little billiard in an antique shop last weekend and when I saw the blue dot on the stem and saw the classic English shape of the bowl I truly thought I had found an elusive Sasieni one dot pipe. Lots of things about it seemed to signal that is what I had. The stamping was hard to see under the grime but there were i’s and an e. I was hopeful and I guess also wishful in my thinking. The pipe was dirty as can be seen below. The stem had obviously been damaged and cut off by the previous owner and a new button filed into the stem. The bowl was badly caked and the rim was damaged with dents and chips. I took the picture below while I was relaxing in a pub near the shop and looking over the finds of the afternoon.

When I got home I took it to the basement and wiped down the bowl with acetone on a cotton pad to remove some of the grime. Once the outside was wiped down I tried to read the stamping with a magnifying lens. I could not make out the stamping – it was too faint. There was no stamping on the right side of the shank. On the underside it appeared that there had been stamping but it was no longer visible. The next three photos give a good idea of what the pipe looked like before I did a cleanup on the bowl and stem.

I reamed the bowl with a PipNet reamer and took it back to bare wood. I picked at the inside of the bowl to check out the solidity of the walls and to check for potential burns. Everything looked and felt like it was solid so I dropped the bowl in an alcohol bath to soak over night.

The next day I took it out of the bath and dried it off. The bath had removed the old finish for the most part. I finished by once again wiping it down with acetone on a cotton pad. After soaking part of the stamping had become visible. I was disappointed that it appeared that the pipe was not a Sasieni. The stamping that showed up after it was dry read Genuine Briar, which seemed to point to an American made pipe post WW2. I believe it is post war as that is when it became necessary to identify genuine imported briar in contrast to the Manzanita and other alternatives used by American manufacturers during the war years due to a shortage in briar. The briar was a nice piece – birdseye on one side, nice grain on other parts of the pipe and a clean shape to the bowl. I knew it would clean up nicely.

I topped the bowl using my normal method of anchoring a piece of sandpaper on a flat board and twisting the top of the bowl into the sandpaper until the top is smooth. I started with 220 grit sandpaper and then used a medium and fine grit sanding block to smooth out the rim.

When I had finished topping the bowl I wiped it down with acetone and a soft cotton pad to remove the sanding dust and the grime from the topping process.

The stem had a poorly cut button on the end and the button as well as the taper on the stem needed to be reworked. I used a rasp and file to shape the taper on the stem and to take out the pinched look of the angle to the 90 degree cut on the button. The button was also not straight and not squarely cut so I also straightened out the flat edge of the button while I worked with the rasp and files. The next three photos show only the initial work on the stem and not the finished work. I removed quite a bit of the material and smooth out the slope of the taper so that it flowed evenly into the button on both the top and the bottom of the stem.

I sanded the newly shaped stem with 220 grit sandpaper and a medium grit sanding sponge to remove the scratches left by the rasp and files. Once I had the basic shape in place I decided to restain the bowl. I warmed the briar and then gave it several coats of a dark brown aniline stain thinned 1:1 with isopropyl alcohol. I flamed it between each coats to set the stain. The rim took extra coats to match the colour of the rest of the bowl.

I buffed the newly stained bowl lightly with White Diamond and then gave it a coat of a light cherry coloured Danish Oil. Once dry I buffed it by hand and then also gave it a light buff with White Diamond to polish it.

I then removed the stem and worked on the slot in the button. When the end of the stem had been cut off some of the flair of the original airway remained leaving the end of the button with a small rectangular opening. I used needle files to open the flair and widen the slot into more of an oval that extended the width and height of the button end.

Once I had the slot opened the way I like it I sanded the inner edges with a folded piece of sandpaper to smooth it out. I also did some more shaping with files to the taper of the stems. I sanded it with 220 grit sandpaper until I had the slope well-defined from the tenon back to the button. I also shaped the externals of the button to clean up the angle at the point the button and stem taper met. I also sanded it with a medium grit sanding sponge to remove the scratches left behind and to also remove the oxidation at the stem shank junction.

When I had the scratches removed as far as possible with the sanding sponge I went on to sand the stem with micromesh sanding pads. I wet sanded the stem with 1500, 1800 and 2400 grit sanding pads and the dry sanded with the remaining grits.

I rubbed the stem down with Obsidian Oil and rubbed it into the surface of the vulcanite. I took it to the buffer and buffed the stem with White Diamond. I gave the bowl and the stem multiple coats of carnauba wax and polished the pipe with a clean flannel buff to bring up the shine. The finished pipe is pictured below. I still wish I knew what the stamping says in full. That blue dot certainly is a symbol of some unknown to me brand of pipe. The mystery remains but in the mean time I have a great little billiard to enjoy.
