Restoring and Repairing a Cracked Shank & Broken Tenon on a Portland oval shank 60 Egg

Blog by Steve Laug

I am still doing some repairs for a local pipe shop and this one came from a referral from them. I have fixed several pipes for this particular pipeman in Vancouver including banding, restoring and fitting a new stem. He stopped by last weekend and dropped off a pipe to be reamed and cleaned and also this relatively new pipe that he had dropped. It is an interesting looking pipe with mix of nice grain around the bowl sides. It was stamped on the underside of the shank and read Portland [over] Bruyere Garantie followed by the shape number 60 near the shank/stem junction. He had only smoked it a couple of times before he dropped it. The stem snapped off leaving the tenon in the shank. When I looked it over there were also cracks on the top of the shank that happened at the same time. The stem was dirtier than the bowl but overall it was in good condition. I took some photos of the pipe before I started working on it. I took photos of the rim top and the stem surfaces to chronicle the condition. The rim had some darkening from his lighter toward the right front of the bowl and on the back side. There was not any cake in the bowl as it was still quite new. The stem was just dirty with light tooth marks on both sides near the button. The tenon had snapped off very close to the stem so it would be a simple process to add a new tenon.I took a photo of the stamping on the shank underside. It is clear and readable.I took a photo of the parallel cracks on the top of the shank. These were hairline but they were present and though you cannot see it they go to the end of the shank.I began my work on this pipe by pulling the broken tenon. I always use a coarse threaded screw and gently turn it into the airway in the broken tenon. I carefully wiggle it free. If it is tight a short 10 minutes in the freezer takes care of that. I went through my box of tenons and found a threaded one that was close to the diameter of the older broken tenon. It would need to be shaped but it would work.Before working on the stem I decided to put the band on the shank and repair the crack and protect it from going further. They are very fine cracks and I decided not to drill it as the hole would be bigger than the cracks. A tight fitting band would pull it together. I reduced the depth of the band with a topping board to make it thin and give a daintier look than the big clunky band. It is a thin brass band and it is pressure fit in place on the shank. I heated the band with a lighter and pressed it onto the shank. I like the look of the banded shank in the photos below.With the band fitted it was time to work on the tenon and the stem. I used my Dremel and sanding drum to make the tenon smaller in diameter to match the shank. I worked on it until the fit in the shank was snug but not tight.With that finished it was time to drill out the stem. I used the Dremel and sanding drum to flatten out the broken tenon end on the face of the stem. I started drilling with a bit slightly larger than the airway and finished with a bit that would allow the threaded tenon to fit the stem.I do not tap the drilled hole in the stem. Rather I flatten out the threads slightly as they provided the grip for the glue when I insert the tenon in the stem. I coated the threaded tenon end with black superglue which dries more slowly than the regular glue and allows me to make adjustments in the fit. I checked the fit in the shank and was pleased with it. I set the stem aside so the glue could cure.I turned my attention to polishing the bowl. I polished it with micromesh sanding pads – dry sanding it with 1500-12000 grit pads. I wiped the briar down with a damp cloth after each sanding pad. The pipe really began to take on a shine as I worked through the pads. I rubbed the briar down with some Before & After Restoration Balm. It works to protect, clean and enliven the briar. I rub it in with my finger tips and let it sit for 10 minutes. I buff it off with a cotton cloth to remove the excess and give the bowl a shine. I polished the stem and new tenon with micromesh sanding pads – 1500-12000 grit pads. I dry sanded with the pads and wiped the stem down with Obsidian Oil after each sanding pad. I finished the polishing with Before & After Pipe Stem Polish – both Fine and Extra Fine. I gave it a final rubdown with Obsidian Oil.I put the stem back on the bowl and polished the pipe with Blue Diamond on the buffing wheel to give it a shine. I gave it multiple coats of carnauba wax and buffed it with a clean buffing pad. I hand buffed it with a microfiber cloth to deepen the shine. I took some photos of the pipe before calling the pipeman to pick up his pipe. I am pleased with the look of the Portland Bruyere Garantie 60 Egg and the fit of the repair band and the stem to the shank. I think it will meet his expectations when he picks it up later today. Thanks for walking through the repair with me in this blog. Cheers.

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

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. It 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.The 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.Obviously 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.I 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.I 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. I 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.The burned area on the top of the bowl made it necessary to top the bowl on the topping board using 220 grit sandpaper.I 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.I 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.I 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.I 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. I 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. I gave the bowl a first coat of Medium Brown Stain with a staining pen to serve as an undercoat. I 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.I 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. I 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.I 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.I 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.
