In a recent trade with Andrew Selking I received an older KBB Yello Bole Paneled billiard. When I removed it from the box there was something about the older KBB Panel that grabbed my attention. It was stamped on the left side of the shank with the familiar KBB logo and the Yello-Bole next to it. Underneath that it bore the stamp Reg. US Pat. Off. Directly below that was stamped Premier over Cured with Real Honey. The pipe had been repaired at some time in its ragged existence with what appeared to be a homemade repair job. The tenon had broken somewhere along the line and a previous owner had drilled out the stem and used a piece of stainless steel tubing to make a new tenon. The metal tenon was stuck in the shank of the pipe and the stem just sat loosely on it. The fit of the stem to the shank was off with the stem sitting high and to the right. The previous owner had tried to compensate for the off centered stem by sanding flat spots on the stem sides and bottom that broke the smooth lines of the square shank and stem. There were two small hairline cracks on the shank – top right and bottom left that would need to be repaired once the tenon was removed. The bowl was out of round with damage to the inner edge of the rim and a tarry build-up on the surface. The outer edge rim crown of the bowl was also compromised and would need some work. The stem was not too badly oxidized but it had tooth marks on the top and bottom near the button.

Background Information
I wrote about the history of the KBB stamped Yello-Bole Pipes. The following link will give you the details: https://rebornpipes.com/2014/07/21/renewing-an-old-kbb-yello-bole-honey-cured-briar-billiard/
Yello-Bole pipes are one of my favorite older US brands doing the research would be enjoyable. As with other early brands made in the states I have found that older is better. A KBB in a cloverleaf stamp will date them back to the ’30’s. I have found through my reading that the 4 digit shape numbers are older than 2 digit ones. The pipes with the logo on top of the stem are older than ones that have them on the side. That is just some of the information that I found with a cursory read through the forums and a variety of websites.

The SM Frank website http://www.smfrankcoinc.com/home/?page_id=2 gives a wealth of historical information on Kaywoodies, Yello-Boles and the merger between KBB and SM Frank and later Demuth. It was a great read and I would encourage others to give the website a read. I also wanted to find some help in dating my old Yello-Bole Pipes and I came across this link to the Kaywoodie Forum: http://kaywoodie.myfreeforum.org/archive/dating-yello-bole-pipes__o_t__t_86.html . I am including some of the information I found there as it gives the only information that I found in my hunt to this point.
“…there isn’t a lot of dating information for Yello-Bole pipes but here is what I have learned so far.

– If it has the KBB stamped in the clover leaf it was made 1955 or earlier as they stopped the stamping after being acquired by S.M. Frank.
– From 1933-1936 they were stamped Honey Cured Briar.
– Pipes stems stamped with the propeller logo they were made in the 30s or 40s no propellers were used after the 40s.
– Yello-Bole also used a 4 digit code stamped on the pipe in the 30s.
– If the pipe had the Yello-Bole circle stamped on the shank it was made in the 30s this stopped after 1939.
– If the pipe was stamped BRUYERE rather than briar it was made in the 30s.”
Given the above information I discovered that the pipe I was working on was made sometime between 1930 and 1940. Thus it was an early Yello-Bole from the 1930s or 40s.

Restoration Process
I took the stem off the bowl and tried to remove the inserted metal tenon. It was firmly stuck in place and I could not move it even with pliers. I put the bowl in the freezer overnight hoping that the cold would contract the metal and briar differently (as is the case with the varied material and density). In the morning I took it out of the freezer and was able to turn the tenon out of the shank with pliers. Once it was removed it was clear to see that it had not been glued in the shank but merely stuck with the tars and oils of the tobacco in the shank. I found a threaded Delrin tenon in my box of tenon parts and it was a workable replacement for the metal tenon. I tapped the drilled out hole in the stem and screwed the threaded tenon into the hole. It was a perfect fit. I removed it once again and put some glue on the threads and screwed it into place and let the glue set. The diameter of the tenon would need to be adjusted as it was too big for the mortise. This was actually ideal in that I would be able to adjust the fit against the shank on the sides and the top. The bottom of the shank would take work to make a smooth transition.

I sanded the tenon with a Dremel and sanding drum to remove the excess Delrin. I hand sanded it with 180 grit and 220 grit sandpaper to smooth out and fine tune the fit. I spread the hairline cracks with a dental pick and dripped superglue along the cracks and pressed them together until the glue set. The stem fit in the shank nicely. The photos below show the damage that had been done to the stem in the previous repair. It is especially visible in the photos of the pipe from the side and the bottom. The stem had been modified to the misfit of the previous tenon so work would need to be done to realign the fit against the end of the shank.

I sanded the bottom, top and right side of the shank until the transition between the briar and the vulcanite was smooth. The left side was touchier in that I did not want to damage the stamping. I sanded this area while covering the stamping. The trick was to smooth out the transition without making a drastic dip in the briar – it just needed to be re-tapered until it flowed naturally into the stem. Sanding the top of the stem also took care as it had the insert of the white propeller. Too much sanding on the top would damage and compromise the insert. The photos below show the newly sanded and tapered shank/stem. I sanded with 220 grit sandpaper, medium and fine grit sanding sponges and a fine grit sanding block. I sanded the rim and curves of the rim with the same sandpapers. I folded a piece of 220 grit sandpaper and worked on the out of round bowl to clean it up as much as possible.

I wiped the bowl and shank down with acetone on a cotton pad to remove the finish from the bowl.

I cleaned out the bowl and shank with isopropyl alcohol, cotton swabs and pipe cleaners. I cleaned out the stem as well at the same time. I sanded the bite marks on the top and bottom of the stem with 220 grit sandpaper to minimize the damage and remove the tooth chatter. There were still some tooth marks that needed to be repaired.

I scrubbed the areas around the bite marks with alcohol to clean the sanding dust and grit from around them. I then used black superglue to fill the bite marks and sprayed it with and activator/accelerator to harden it.

When it dried I sanded the filled areas with 220 grit sandpaper to level them out with the surface of the stem. I sanded the stem with a medium and fine grit sanding sponge and a fine grit sanding block to further blend the patches into the stem surface. In the next two photos the patches are blended into the stem but the blackness of the super glue and the blackness of the unpolished stem do not match so they show up as spots on the stem.

I stained the bowl and shank with a medium brown aniline stain thinned 50/50 with isopropyl alcohol. I wanted a medium brown wash to highlight the grain and show contrast in the finish. The wash provided just what I was looking for.

I sanded the stem further with fine grit sanding blocks and also sanded the flat areas on the transition between the shank and stem to work towards a more seamless look. The next photos show the smooth transition and the smooth stem. The patches are fading more into the vulcanite of the stem as well at this point in the process.

I moved on to sand the stem with micromesh sanding pads – wet sanding with 1500-2400 grit pads and dry sanding with 3200-12,000 grit pads. I rubbed down the stem between each set of three pads with Obsidian Oil and then continued sanding. I have found that sanding the stem while the oil is freshly applied allows the grit on the pads to cut into the finish and raise a shine.

The next two photos show the finished stem. After the final sanding I rubbed it down with Obsidian Oil and let it soak in before polishing it with the buffer. I gave it several coats of carnauba wax. The patches on the stem by this point are fully blended into the vulcanite and cannot be identified.

The next photo shows the reworked inner edge of the rim to show my repairs on the out of round bowl. I sanded until it was as close to round as I could get it by hand. I bevelled the inner edge of the bowl with the sandpaper to make the transition smooth. The finished pipe is shown below. Thanks to Andrew for sending me this challenge. I really enjoyed bringing this old timer back to life. It will occupy a special spot in my older American pipe maker collection and join my other KBB Yello-Boles as favourites that I enjoy smoking. I buffed it with White Diamond and gave it multiple coats of carnauba wax and finished by buffing it with a soft flannel buffing pad to raise the shine. All that remains is to sit back and enjoy a bowl of an aged Virginia tobacco and read a good story!
