Restoring and Replacing a Broken Tenon on a Scandia 263 Danish Freehand

Blog by Steve Laug

I am currently not taking on anymore restoration work from the internet or groups that I am part of on Facebook because of the large amount of estate pipes that I am working on to sell. But I have my name in at a local pipe shop here in Vancouver, British Columbia to do repair work for the shop as it comes in. there are no other pipe repairers in Western Canada that I am aware of so I feel a bit of an obligation to take care of these folks as they come. Fortunately there are not a lot of referrals but periodically they get pipemen or women stopping by with work – that is where I come in. They give them my number and email and then the repair work is between us. On Wednesday this week I received an email from one of their customers, Ron in Victoria, B.C. about a pipe that had been dropped and had a broken tenon. He described the broken stem and that left me with some questions. I had him send me photos of the broken pipe so I would be sure to have a clear picture of the issues. He said that the shank was not cracked and really the only issue was the tenon. He send the photos below so I could see what he was speaking of. Not too big an issue really – a cleanup and tenon replacement and the pipe would be good to go.After our emails back and forth he put it in the mail to me. It arrived on Friday and I took it out of the box to see what I was going to be dealing with on this pipe. Descriptions and photos are one thing but I like to have the pipe in hand to examine for myself. This is what I saw. The pipe was dirty and dull looking. There was some faint stamping on both sides of the shank. It was stamped Scandia over Made in Denmark on the left side and had the shape number 263 on the right side. There was a very uneven cake in the bowl that was crumbling. The tenon had snapped off almost smooth against face of the stem. The stem had some tooth marks and was oxidized. There was a faint SC on the left side of the saddle. It appeared that someone had tried to glue the tenon back on the stem – unsuccessfully. There was a lot of sloppy glue on the end of the stem and tenon. I took some photos of the pipe as it looked when it arrived. He had taped the broken tenon on the underside of the stem. The bowl itself was dirty with a crumbling cake about half way up the bowl from the bottom. The plateau rim top had tars and some darkening on the right top and edges. There was a large sandpit on the left side of the bowl near the rim and one on the underside of the shank that would need to be dealt with.  I removed the taped on broken tenon from the stem. I used a Dremel and sanding drum to take down the sharp edges of the old tenon remaining on the face of the stem. I wiped the face down with acetone on a cotton swab to remove the old glue. It was a sticky mess but came off quite easily with the acetone. When it was clean I used a series of drill bits to drill out the airway to accommodate the new threaded tenon. I usually start with a drill bit slightly larger than the airway and work my way up to the one that fits the tenon end. I used my cordless drill and the airway as the guide for each successive drill bit. This keeps things lined up.Once I have the airway drilled to accommodate the end of the tenon. I use a tap to thread new airway. The tenon replacements I use have a hip around the middle that I need to take down. I use a Dremel and sanding drum to smooth things out. I also rough up the threads to reduce the diameter to make room for the glue that I use to set the tenon in the stem.I used a needle file to smooth out the slight ridge at the end of the tenon. I sanded the tenon smooth to clean up the fit. I would further polish it once it was in place in the stem. I dribbled some Krazy glue on the threads and quickly turned it into the stem making sure that the alignment was correct.I took photos of the new tenon before I polished and finished it. The tenon is solid and the alignment in the shank is perfect. I set it aside to cure and turned my attention to the bowl.With the stem repaired I remembered that Ron had asked me to give him some background information on the brand so I paused at this point to gather the info. I turned to Pipephil’s site (http://www.pipephil.eu/logos/en/logo-s4.html) to get a quick overview. As expected the Scandia brand is a Stanwell second line. In this case the sandpits make it clear why it has this designation. I have included a screen capture of the pertinent section from the site.I turned then to the section on Pipedia that dealt with the Stanwell Sub-brands the Scandia pipe listed there (https://pipedia.org/wiki/Stanwell#Sub-brands_.2F_Seconds). I followed several other links listed on the article to check who designed this particular shape for Stanwell (https://pipedia.org/wiki/Stanwell_Shape_Numbers_and_Designers). Bas Stevens, a dear friend who know longer is living compiled a list of the shape numbers and their designer. The 263 was not listed there however, I remembered that the shape was actually a Stanwell shape 63. That shape was a Freehand with a plateau top and a saddle mouthpiece and was designed by Sixten Ivarsson.

To verify that my memory was correct I did a quick Google search for images of the shape 63 for comparison purposes. I include the photo below with thanks to http://www.Bollitopipe.it for the image (https://www.bollitopipe.it/en/hand-made-polished-royal-guard/18983-stanwell-royal-guard-63-bark-top.html). You can see that the shape is identical so that it is clear that the 263 and the 63 are the same shapes.With the background information gathered and summarized I turned my attention to the cleanup of the bowl. I reamed the crumbling and uneven cake out of the bowl. I left a very thin cake on the walls of the bowl. I cleaned up the small bits toward the bottom of the bowl with a Savinelli Fitsall Pipe knife. I finished by smoothing out the slight cake on the walls with a piece of 220 grit sandpaper wrapped around some doweling. I a soft bristle brass brush to clean off the debris in the plateau finish on the rim top. I was able to remove most of the darkening at the same time. While not flawless it looks significantly better.To clean the surface of the briar and remove the oils and dirt I scrubbed the briar with a tooth brush and undiluted Murphy’s Oil Soap. I rinsed off the bowl under warm water and dried it off with a soft cotton cloth. The finish looks much better with stunning grain. The sandpits are quite visible now that the pipe is clean. I repaired the sandpits with a few drops of Krazy Glue. I slightly overfill the pit with the glue as it shrinks as it cures. Once the repairs cured I sanded them with 220 grit sandpaper to blend them into the rest of the bowl. I polished the entire bowl with 400 grit wet dry sandpaper in preparation for the micromesh polishing. I polished the briar with micromesh sanding pads – wet sanding with 1500-12000 grit pads. After each pad I wiped the bowl down with a damp cloth to remove the sanding dust. The photos tell the story. I used a black Sharpie pen to darken in the deep grooves on the plateau as it would help to mask the darkening on the right and left side of the rim top and it would highlight and give depth to the finish. I rubbed the bowl down with Before & After Restoration Balm. I worked it into the surface of the plateau rim top and the rest of the briar with my fingertips and a horsehair shoe brush to clean, enliven and protect it. I let the balm sit for a little while and then buffed with a cotton cloth to raise the shine. I really like watching the Balm do its magic and bring the briar alive. With the bowl finished I turned my attention to polishing the stem. I sanded the surface of the stem with 220 grit sandpaper and 400 grit wet dry sandpaper to remove the remaining oxidation in the vulcanite and the last of the light tooth chatter.  I polished the stem with micromesh sanding pads – wet sanding with 1500-12000 grit pads. I wiped the stem down after each sanding pad with Obsidian Oil. I used some liquid paper to touch up the “SC” on the left side of the stem. I applied it and let it dry and cure. Once it had cured I scraped the excess off with a tooth pick. The “SC” looks very good.  I polished it with Before & After Pipe Stem Polish – both Fine and Extra Fine. Once I had finished the polishing I gave it a coat of a new product I am experimenting with from Briarville Pipe Repair. It is called “No Oxy Oil” and it is made to protect the stem from oxidizing. I set it aside to dry.I am happy with how this pipe looks compared to what it looked like when it arrived in pieces. It definitely has that Stanwell look to it – very Danish Freehand looking. I am excited to be on the homestretch with it and took it to the buffing wheel and polished it on the wheel with Blue Diamond to polish out the scratches in the briar and the vulcanite. I gave the bowl and the stem multiple coats of carnauba wax. I buffed the pipe with a clean buffing pad to raise the shine. I hand buffed it with a microfiber cloth to deepen the shine. The pipe polished up pretty nicely. The grain really pops with the wax and polish. The shiny black vulcanite stem is a beautiful contrast to the blacks and browns of the bowl and shank. This Scandia Made in Denmark Freehand was fun to bring back to life. It really is stunning piece of briar whose shape follows the flow of the grain. The pipe is comfortable pipe to hold in the hand. The finished pipe is shown in the photos below. The dimensions of the pipe are Length: 5 ½ inches, Height: 2 inches, Outside diameter of the bowl: 1 ¾ inches, Chamber diameter: ¾ of an inch. This beautiful pipe will be going back to Ron tomorrow. If the mail is as fast as it was bringing it to me he should have it in hand by the first part of the week. I hope that he enjoys this beauty and that it serves him well. Thanks for reading this blog and my reflections on the pipe while I worked on it. This is an interesting one to bring back to life.

Making Work for myself – Restoring a GDB Rainbow 347

Blog by Steve Laug

I have worked on and collected many GBD pipes over the past 20 years. I have some great resources that I use to identify the nomenclature, shape and date of the various lines that GBD issued. However, all of my sources and resources regarding GBD are from the time prior to the merger (Cadogan) or shortly thereafter. The Rainbow Line is not mentioned in any of them. I also looked on the pipephil Logos and Stampings site and Pipedia and again there is no mention of the line. In my online research, I found several people who think that it is probable that the pipe was made during the 70’s through 90’s. Several things point to this – the chunky Lucite stem, the name of the line itself and the brightly coloured stems used. One fellow on Pipes Magazine’s online forum had a great quote that caught my attention. He said, “If you’re old enough you might remember that Rainbow was a popular theme in the late 70’s to early 90’s due to Sesame Street, “The Rainbow Connection,” The Rainbow Reading Room, etc.” http://pipesmagazine.com/forums/topic/help-with-info-on-a-gbd-pipe I think this is as close as I am going to get to a time period when the pipe was made.

The pipe I picked up on a recent trip to Idaho is a nicely shape apple that was in pretty decent shape. I figured it would be an easy clean up. But things happened along the way and I made more work for myself. It is stamped GBD in an oval over Rainbow on the left side of the shank. On the right side stamped London, England in a straight line over 347 (shape number). On the underside of the shank near the stem/shank junction it is stamped D. The faint painted GBD in an Oval on the left side of the stem also suggests a later GBD. The nomenclature is consistent with usual smooth GBD markings (GBD over Grade (left side) and London England over style number on the right side.) The photos below came from the person I purchased the pipe from and show the general condition.He provided some close up photos of the bowl and rim. He said that the pipe had been reamed and clean. However, it was not reamed and clean to my liking. The bowl had a thick cake that I will need to remove, some rim darkening and some dents in the rim. My guess was that like the bowl, the shank and mortise would need some attention. The stamping on the shank was very clear. The first photo below shows that. Next to the shank/stem junction in the first photo, there is also the remnant of the GBD oval logo that had been originally painted on the stem. The stem had a lot of tooth chatter and some shallow tooth marks in the Lucite.While I was staying with my brother, I cleaned and reamed the pipe. I used the PipeNet reamer and took it back to the walls. I would need to clean it up more once I got home but it was better than when I started. Last evening I took the pipe out of the box to finish the clean up and restoration. I took some photos of it before I started to have a benchmark. I took a close up of the bowl and rim. It was better than when I started but still needed to be cleaned up some more. The rim had some darkening that I could reduce some more as well.I used the Savinelli Fitsall Reamer to scrape the remaining thin cake from the walls of the bowl. I personally like to remove all of the cake when cleaning up a bowl. I will sand a bowl interior a bit later to smooth things out. Little did I know at this point that the decision to sand the bowl would send me on a repair detour.I scrubbed out the mortise, airway in the bowl and in the stem with alcohol, cotton swabs and pipe cleaners. I used the dental spatula to scrape the walls of the shank and remove the hard tars that had built up there. The airway in the stem was also dirty and had some darkening at the button and in the first few inches of the stem. I cleaned it with bristle pipe cleaners and picked the debris out of the button and from around the stem down tenon with a dental pick.The stem not only had tooth chatter but also some stickiness from a price tag on the top surface. The edge of the button also had some chatter. I sanded the tooth marks out with 220 grit sandpaper and reshaped the button at the same time. The stem was smooth when I finished. It was dull and needed a good polishing.I polished it with micromesh sanding pads – wet sanding with 1500-2400 grit pads and dry sanded with 3200-12000 grit pads. I wiped the stem down with a damp cotton pad to remove the dust after each pad. I was finished with the stem at this point so I set it aside to work on the bowl. I had decided to use a dark brown aniline stain thinned by 50% with alcohol to darken the grain on the pipe and hide a couple of small fills. I applied the stain, flamed it and repeated the process until the  bowl was covered evenly. I wiped the bowl down with cotton pads and alcohol to make it more transparent. I hand buffed it and took the following photos. It was still too dark to my liking. I sanded the bowl with micromesh sanding pads to make it more transparent and to see if I could make the grain pop. I sanded it with 1500-2400 and took these photos. It was getting there. I continued to sand it with 3200-12000 grit pads to polish it and give it a shine. The next photos tell the story. The bowl was looking better and better. It is at this point that I made a decision that would inevitably cost me. That results of that decision turned out to be a mistake that made a lot more work for me! I put the stem on and decided to work on sanding out the inside of the bowl to remove the polishing compound and remnants of cake. Stupidly, I put the stem on the pipe to enjoy the look of the combination while I worked. Wrong thing to do! Understand, I was sitting at my work table, the top of which is a meter above the floor. I was carefully sanding the bowl interior so as not to damage the nice stain on the rim. Somehow, the pipe wiggled free from my hands and fell to the floor. If you could have watched it and my face at the same time you would have seen the look of horror on my face as it dropped to the floor. That horror changed to a moment of dread as I watched it bounce and heard a snap and watched as the bowl and stem went in opposite directions. I quietly picked up the bowl and stem. The tenon had snapped off in the mortise. It was a clean break. I don’t know about you but I find Lucite is much less forgiving than vulcanite. I have had pipes with vulcanite stem hit the floor with not breakage but not so with Lucite. It seems that the tenon inevitably snaps. Well this one certainly did.I sat and looked at it for a long time just sick at the thought that a pipe I was basically finished with was in pieces on my table. I know how to replace a tenon; that is not a problem. I just did not want to have to do that on this pipe. However, my own stupidity and carelessness had successfully sent me back to work on this pipe. Ahh well… just as well call it a night. Perhaps a good night’s sleep would give me better perspective on this new problem!

I woke up early this morning and dragged my feet about going back to work on the pipe. I think I was hoping at some level that it had not actually happened. I sipped my coffee as long as possible postponing the inevitable. I talked with my eldest daughter who is in Kathmandu for work. I took the dog for a walk around the yard… but finally I made to the basement and the work table. It was not a dream the tenonless stem and the bowl was sitting waiting for me.

I used the Dremel to remove the remnants of the old tenon that were on the face of the stem. I flattened it against the topping board. I went through my assortment of threaded Delrin tenons until I found one that was slightly larger than the broken one. I needed to reduce the diameter slightly to make it work but it would do!I set up my cordless drill and put in a bit slightly larger than the airway and turned the stem onto it by hand. The first photo below shows the bits I used as I repeated the process until the hole was large enough for me to use a tap to thread it to match the tenon. The second photo below shows the last drill bit I used the piece of tape on the bit is to show me how deep I needed to go with the bit to accommodate the new tenon threads.I roughened the tenon surface so I could grip it enough to turn it into the newly drilled stem end. It was a good fit. I painted the end with some epoxy and turned it back in place and set it aside to cure and harden.Once the tenon was set firmly in place I used the Dremel and sanding drum to reduce the diameter to a close fit. I finished the fitting with 180 and 220 grit sandpaper. I polished the new tenon with micromesh sanding pads. Now came the telling moment. Would the stem match up with the shank? Would the fit be tight against the shank end? Even though I have done this many times I always have the same questions. I placed the new tenon in the mortise and carefully pushed the stem against the shank end. It was a very close fit and all I would need to do was sand the left side and top a little bit to make the fit even better. I was relieved and happy. I sanded the stem with 220 grit sandpaper and cleaned up the fit. I was almost back to where I was last night before the pipe dropped and the tenon broke. I have to polish the stem once again but the stem fits well. I took photos of the pipe at this point to check it out. The newly fit stem and the stain on the pipe worked well together. Now to polish it all and get it finished. I polished the bowl and stem with micromesh sanding pads – dry sanding with 1500-12000 grit pads to raise the shine.I buffed the pipe and stem with Blue Diamond on the buffing wheel. I gave it multiple coats of carnauba wax and buffed it with a clean buffing pad to raise the shine. I hand buffed it with a microfibre cloth to deepen that shine. The finished pipe is shown in the photos below. I am pretty happy with the way it turned out – even with the detour. The stain accomplished what I hope it would in making the grain pop. The grain stands out like it never did in the pipe when I received it. Now it is visible. It is a nice looking pipe that feels good in the hand. Thanks for looking.

 

Restemming and Restoring a Tiny KBB Rocky Briar 1540B Salesman’s Pipe

Blog by Steve Laug

In the box of pipes my brother sent me was a beat up leather pipe and tobacco pouch. I pushed it aside and cleaned up the rest of the pipes in that particular part of the box. The other evening I was doing a bit of sorting and I took out the pouch and looked it over. It had a large tear on the bottom edge. The zipper was worn and hard to work and the leather was brittle. I almost tossed it in the bin but felt something inside of the pouch. I looked at the inside of the underside of the pouch and there was nothing there. I open the broken zipper on the top of the pipe and inside was a very small – tiny if you will – pipe. The tenon was broken and the stem and bowl sat in the pouch.  I took it out of the pouch to have a look. KBB1It was a KBB that was stamped Rocky Briar. Why it bore that stamp I have no idea as it is a smooth briar. There is no rustication or and carving on the bowl at all – just very smooth. Underneath the KBB in a cloverleaf stamp and the Rocky Briar on the left side of the shank it read Reg. Pat. No. 298978. On the right side of the shank it reads 1540B which it was the shape number. All of that seems very normal but did I say that this pipe is tiny? It is only 4 ¾ inches long, 1 1/8 inches tall. The diameter of the bowl is 5/8 inches and the chamber is 7/16 inches in diameter. All is proportional and well laid out. It makes me wonder if it was not a salesman’s pipe.KBB2The tenon was snapped in the shank but no damage had been done to the shank itself. Really the pipe looked quite good other than the broken tenon.KBB3Obviously the pipe had been smoked and quite often. There was a fairly thick soft cake in the bowl and the rim top had a coating of tars and oils. The back left side of the rim had a burn mark on it that was quite large.KBB4I took a photo of the pipe before I began to work on it. The finish was very shiny – like it had been given a coat of varnish. The rim was obviously rough as you can see from the photos but the rest of the pipe looked good. The stem had tooth chatter on the top and the bottom of the stem near the button. The logo on the shank was a clearly stamped circle within a circle. The broken tenon would need to be pulled and if possible the stem given a new tenon.KBB5I used a drywall screw to pull the broken tenon. I screwed it into the broken tenon in the shank and wiggled it free. Before I pulled it out of the shank I took the following photos.KBB5a KBB5bI pulled the piece of tenon out of the shank and reamed the bowl with the only reamer that would fit in the tiny opening – a Savinelli Pipe Knife. I scraped back the cake to bare briar.KBB6The burned area on the top of the bowl made it necessary to top the bowl on the topping board using 220 grit sandpaper.KBB7I scrubbed off the briar with acetone on a cotton pad. I wanted to clean off the sanded rim and the shiny coat on the bowl so that it would be easier to stain the bowl and rim to match.KBB8I used the Dremel and sanding drum to flatten the face on the stem and then set up my cordless drill to drill out the end of the stem. I hand twisted the stem onto the drill bit. I started with a bit slightly larger than the airway in the stem and worked my way up until I had opened up the airway large enough to hold the tenon in place.KBB9I decided rather than trying to turn a small tenon that would fit in the shank I would clean up and use the existing broken tenon. Fortunately on these old pipes the tenon was quite long. I glued the broken tenon piece into the newly drilled opening in the stem with black super glue. I filled in around the tenon piece with the super glue using a dental pick and a piece of paper clip. I smoothed out the glue and aligned the tenon in the shank and set the stem aside to let the glue cure. Once it hardened, I sanded the new tenon with 220 grit sandpaper to remove the excess glue and make the fit in the shank smoother.KBB10I put the stem in the shank and sanded the shank and stem to make the transition smooth. Once I had the stem fit adjusted I sanded the shank and stem with a 1500 grit micromesh sanding pad to remove the scratches.KBB12 KBB13I wet sanded the stem with 1500-2400 grit micromesh sanding pads. I rubbed it down with Obsidian Oil. I dry sanded it with 3200-4000 grit pads and gave it a second coat of oil. I finished sanding it with 6000-12000 grit pads and gave it a final coat of Obsidian Oil. I set the stem aside to dry.KBB15 KBB16 KBB17I gave the bowl a first coat of Medium Brown Stain with a staining pen to serve as an undercoat. KBB18I realize that for many of us who read about pipe restoration the measurements of this pipe really do not give a clear picture of the true size of the pipe. To give more of a sense of perspective to the diminutive size of the pipe I decided to take two photos of the tiny bowl with a regular sized Comoy’s long shank billiard. The first photo shows the pipe above the larger one. The second photo shows the bowl fitting inside of the regular sized bowl. Hopefully that helps give you a clear idea of the tiny nature of the pipe.KBB19I gave the bowl a second coat of stain using a Danish Oil Cherry stain. I wanted a bit of contrast to the brown and also to enhance the reds in the briar.KBB20 KBB21I rubbed the bowl down with a soft cotton cloth to spread the stain coat out and rub it into the briar. The next photos show the look of the pipe after a quick hand buff.KBB22I buffed the bowl with Blue Diamond on the buffing wheel to polish it. I gave the bowl several coats of carnauba wax and buffed it with a clean buffing pad. I hand buffed it with a microfibre cloth.KBB23KBB24I gave the bowl and stem another coat of carnauba wax and lightly buffed it with a clean buffing pad. I hand buffed the entire pipe with a microfibre cloth. The finished pipe is shown in the photos below. It came out really nicely. Looking at the pipe is hard to tell from the photos the tininess of the pipe as all is proportional. The seashell in the photo is the same one that I use in all of the final photos and with this pipe it seems quite large. Thanks for looking.KBB26 KBB27 KBB28 KBB29 KBB30 KBB31 KBB32 KBB33

Replacing a tenon in a stem with a minimum of tools

5 Replies

Last evening I was looking at the lone pipe bowl in my refurbishing box and decided I wanted to do something with it. I wasn’t sure if I would refinish it or rusticate it with the new tool Chris sent me. Either way though, it needed a new stem. I went through my can of stems and found that I did not have any that would fit the shank without a lot of work. I did have one with a broken tenon that was the right diameter for this pipe. I looked at it for a while and then found a Delrin tenon that I had on the work table. The tenon was the right size for the shank! The stem was the right diameter for the shank. Now all I had to do was wed the two of them and I would have my new stem.

I have drilled out broken stems in the past and inserted a new tenon. I have used a tap and then screwed in a threaded tenon that I purchased from Pipe Makers Emporium. Either way it was work that I did by hand. By hand means that I do not have a drill press, I do not have a vise to hold the stem. I have my two hands and a cordless drill. This takes steady and slow work to keep all the angles straight and get things properly aligned. It is one of those processes that will either work really well or not at all. There is no in between. You cannot redrill a crooked hole to straighten it out without making it too large to fit the piece. So really the fact of the matter is that it all comes down to whether I can drill the stem out straight!

To begin the process I needed to square up the end of the stem and remove the broken pieces of the tenon that still remained. The end needed to be flat and even for the drilling. I sanded down the end of the stem flush using a sanding board (like the one used when topping a bowl). In the photo below you can see that the end of the stem has a divot out of it due to the breakage. I did not worry too much about that as the drilling would take most of that area out of the equation. I only worked on flattening out the rest of the stem. When finished I pressed it against the end of the shank to see if it was a flush fit or if there were any high spots. The fit was perfect. Now it was ready for drilling.

I took out my cordless drill and found that the battery was dead. I put the battery on the charger and sat thinking for a bit about how to best drill out the stem. I measured the diameter of the new tenon and found that it was 15/16 inches. To make sure I did not crack the stem or break it in the process I would drill it out in stages. I would mark the depth on each drill bit I used with a piece of tape so that I would not over drill or under drill the depth of the hole. I used the tenon as the measure for this. The tenon I had came with a slight lip on it so I would need to countersink the end of the stem once the hole was drilled in order to accommodate the lip.

I decided to try something different this time and not wait for the battery to charge. I stood the drill on my desk, inserted the drill bit and hand turned the stem onto the drill bit. I started with the 11/64 inch bit which was slightly larger than the airway in the stem. I turned the stem onto the stationary bit to the depth that I had marked on the drill bit. I lined up the stem and the angles making sure the line was straight and the hole stayed centered throughout the process. I worked my way through 7 bit sizes up to the 17/64 inch bit. Each time I turned the stem onto the bit in increments and cleaned out the hole with a dental pick. I continued to turn it on and off the bit until the drilling was smooth before moving onto the next sized bit.

I found that when I got to the larger sized bits from 19/64, 5/16, 21/64 inches it was hard to turn them on by hand. I could get them started but they quickly bound up on the bit and I could not turn them further. I turned them back and forth but it was not working well. I put the battery back on the drill and drilled the stem using a very slow speed. It worked well. When I had finished drilling it with the 5/16 inch bit the tenon pressure fit very nicely in the hole. There was not enough room for epoxy to be applied and still fit in the hole, so I drilled it with the 21/64 bit to give it the amount of room for the epoxy. To countersink the end of the stem I used a slightly larger drill bit and then a sharp knife to bevel the inner edge to accept the ridge on the tenon.

In the morning the tenon was firmly in place and dry. I cleaned the face with a dental pick and removed the excess epoxy from the stem. I pushed the stem into the shank of the pipe to see the fit. This was the final test. Did things align properly? Did I get the angle square and straight? Would there be a gap in the stem and shank joint? In case you are wondering I have had all of those issues in the past and had to do a lot of adjustments to get a clean fit. But this time things worked well. The fit was perfect and the alignment was absolutely correct. The pipe now had a new stem and it was time to make a decision on what to do with the finish of the bowl. That will be another story however. The photo below shows the fit of the stem and the shank. I am very pleased with the fit.

I sanded the stem and the shank to get a smooth transition between the stem and shank. I wanted the fit to be seamless so it took some sanding with 220 grit sandpaper followed by a sanding sponge to fine tune the fit. Here is the pipe as it stands now. Later today I will rework the bowl and finish the entire stem. But for the purpose of this post the tenon replacement and fit of the stem to the shank is complete.
