A Straightforward Restemming & Restoration of a Jobey Shellmoor 250 Apple

Blog by Steve Laug

The next pipe I chose to work on was another bowl from my box to restem. This one is a nice sandblast apple. It has a deep and rugged blast around the bowl and shank. When I examined the shank it was threaded which was interesting. Once I saw the stamping that became clear. It is stamped on the underside of the shank and reads Jobey [over] Shellmoor. To the left of that stamp is a shape number 250. Underneath the Shellmoor stamp is another series of numbers – PAT. 3537462. The stamping was clear and readable with a lens. I want to see what I can find out about the Patent number. I don’t recall working on one of those before. The bowl had been cleaned and reamed somewhere along the way by either Jeff or me. I honestly don’t remember when or where we got this bowl. It looked very good and I was looking forward to seeing the finished Apple. The stem was long gone so this would be a restemming job. It would be a different stemming job because of the Jobey Link System so it would be kind of fun. I took some photos of the bowl to give a since of the condition of this nice little Apple. I took some photos of the stamping on the sides of the shank. The stamping is clear and readable as noted above. There was a smooth panel on the underside of the shank. It is stamped as noted above and is clear and readable with a lens.The next photo shows the rounded rim top and edges. It also shows the condition of the bowl and rim top/edges. It is clean looks quite good. I will give it a quick go over with a brass brush but otherwise it looks good.Before I started to work on the pipe I wanted to understand the patent information so I turned to the US Patent search site and entered the numbers. I was able to find both a description of the invention and a diagram that was submitted with the Patent application. Here is the link to the site and a screen capture of the information found there. https://pdfpiw.uspto.gov/.piw?docid=03537462&SectionNum=1&IDKey=6F776849C285&HomeUrl=http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1%2526Sect2=HITOFF%2526d=PALL%2526p=1%2526u=%25252Fnetahtml%25252FPTO%25252Fsrchnum.htm%2526r=1%2526f=G%2526l=50%2526s1=3537462.PN.%2526OS=PN/3537462%2526RS=PN/3537462Now it was time to begin my restemming work on this pipe. I went through my can of tenons and found a Jobey Link that screwed into the shank perfectly. I chose a stem from the can of stems I have here that would the shank well. I would need to remove the standard tenon and drill the stem to receive the end of the tenon. I used a hacksaw to cut off the normal tenon on the stem. That part was very simple but then things went quickly sour. I put a piece of tape on the drill bit to start drilling out the saddle to receive the Link. I started with a small bit and started drilling. The tape move and the bit suddenly came out of the top part of the blade of the stem. Yikes what a mess.Sooo…needless to say the ruined stem went into the waste bin and I had to start over. I chose a new blank from the bag Jeff sent me as the fit was the closest one I had in terms of matching the sides of the shank. I cut off the tenon with the hacksaw. This time I measured the depth of the saddle and the length of the tenon and drilled to match it – very carefully in multiple stages. I checked and rechecked as I did not want to do the work a third time. I used a series of drill bits from one that was slightly larger than the airway and ended with a ¼ inch bit that was the size of the Link.I smoothed out the face of the stem on a topping board with 220 grit sandpaper. I wanted the surface smooth so it would sit well against the shank when the Link was inserted.With the face smoothed out I pushed the snug fitting Jobey Link into the hole in the face of the stem. It fit well against the shank end so that was a plus. Everything lined up so I took some photos of the restem at this point. The casting remnants on the sides of the stem needed to be removed and they were quite rough and messy. I used a flat file (rasp) to flatten out the castings on the saddle and blade sides of the stem as well as the area around the slot in the button. I used my Dremel and a sanding drum to do the rough work on the stem. I worked on it carefully to remove more of the casting marks and to reduce the bottom side of the saddle to match the size of the shank.The only way I know how to do this is with the new stem in place in the shank and then carefully move the sanding drum up and around the stem surface to get a close/rough fit. It was getting much closer but there was a lot more work to do hand shaping it with sandpaper and files.With the majority of the heavy work done it was time to work over the stem with 220 grit sandpaper and get everything aligned. I started the polishing with 400 grit wet dry sandpaper and the stem was looking very good at this point.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 polished the stem with Before & After Pipe Stem Polish – both Fine and Extra Fine and buffed it with a cotton cloth. Once I had finished the polishing I gave it final coat of Obsidian Oil and set it aside to dry. With the stem finished (other than to buff the pipe at the end) I turned my attention to the bowl. I used a brass bristle wire brush to clean up the debris still in the sandblast rim top of the bowl. It looked better when I finished.   I rubbed the bowl and shank down with Before & After Restoration Balm. I worked it into the surface of the sandblast bowl sides and shank with my fingertips and a horsehair shoe brush to clean, enliven and protect the briar. I let the balm sit for a little while and then buffed with a cotton cloth to raise the shine. The Balm did its magic and the sandblast grain really took on dimension and colour. I am excited to be on the homestretch with beautiful sandblast PAT. 3537462  Jobey Shellmoor 250 Apple. This is the part I look forward to when it all comes back together, polished and waxed. I put the bowl and the new stem together and polished the stem and bowl with Blue Diamond to polish out the scratches in the vulcanite and give a light shine to the bowl. I gave the bowl multiple coats of Conservator’s Wax 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 rugged sandblast finish looks really good with the new polished black square saddle vulcanite stem. This Sandblast Jobey Shellmoor Apple was another fun pipe to work on and came out looking great. It is a comfortable sized 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: 1 ¾ inches, Outside diameter of the bowl: 1 ¼ inches, Chamber diameter: ¾ of an inch. The weight of the pipe is 38 grams/1.38 ounces. If you are interested in adding this pipe to your rack it will be on the rebornpipes store in the American Pipemakers Section soon. Thanks for reading this blog and my reflections on the pipe while I worked on it.

Repairing and Refurbishing a Jobey “Gondoli” From Steve’s Grab Box

Blog by Paresh Deshpande

Steve, my friend and mentor, had sent me a pipe lot of 15 pipes for restoration about 3 years back. These assorted pipes were requested by me with an intent that these would provide me with an opportunity to further hone my skills and gain experience in tackling varied issues that one may come across during restoration. Each of these pipes has its own set of issues to address and I look forward to work on each one of this pipe lot. Here is the picture of the pipes as I received it. The one marked with a red cross is a Dunhill Root that has been restored by Steve for my personal collection.

I have worked on a no name straight billiard and an Oom Paul from this lot and both turned out to be beautiful pipes. The next pipe from this lot that I selected to work on is a Jobey “GONDOLI” and is marked with a green arrow and numeral 3.This pipe has a nice hand feel to it and the classic Prince shape with a beautiful variegated fancy stem makes it a very attractive looking pipe. The stummel boasts of beautiful mixed grains. It is stamped on the left side of the shank as “Jobey” in fancy script over “GONDOLI” in capital letters, towards the shank end. On the right side of the shank it is stamped with shape code “965”. The variegated acrylic stem with swirls of brown carries the trademark logo of JOBEY in a brass roundel atop the surface of the stem.I had previously worked on two Jobey pipes and had researched the brand at that time. Here is the link for the research and write on the pipe.  A Simple Restoration of a “Jobey Filtersan # 690” | rebornpipes

No other information was available on the internet that I could link with the GONDOLI line or the shape code # 965. Any assistance in unearthing additional information is most welcome!!

Initial Visual Inspection
This grab bag that Steve had sent me contained few pipes that Jeff had already cleaned and sent across to Steve for further restoration. Thus, unfortunately, before condition pictures are not available with me to share with the readers, but fortunately, I get to work on a pipe that Jeff has already worked his magic upon and presented me with a clean pipe. Below are a few pictures of the pipe as I had received it. Detailed Inspection
The chamber is nice and clean with thick walls without any damage. The rim top surface has a couple of darkened areas which should be easy to clean up. The inner and outer rim edges are in decent shape and the chamber smells clean.The external surface of the stummel has been cleaned and lacquer coat has been removed in most of the places. However, a few spots remain where the lacquer coating is visible. The stummel had a reddish orange stain that has been cleaned out but would need to be eliminated completely (personal choice!). There are a few fills (encircled in pastel blue) at the back of the stummel that would need to be refreshed. There are few dents and dings over the stummel surface that needs attention. Through all this patchy lacquer coat and stain, beautiful Angel’s hair peeks out from the smooth surface. Once the stummel is cleaned and polished, these grains will pop out in all their refined glory. All in all as it stands now, this is one dull and tired looking stummel that requires a lot of TLC!! The mortise is threaded to accommodate the screw-in Jobey link tenon which was patented by Jobey. The mortise is otherwise clean but for the accumulation of dust and grime from three years of storage. This will need to be thoroughly cleaned. The famed Jobey-link Delrin tenon is shown below.The variegated acrylic fancy stem with swirls of browns and grey look very attractive, but to put it mildly, is an utter mess!! It has bite marks (encircled in green) on both upper and lower stem surface with minor tooth chatter all over the bite zone on both sides; however, these should be an easy fix. The real serious damage to the stem can be seen at the tenon end. There is a deep crack from the face of the tenon end on either surface that extends right up to the shoulders of the stem. Along the way this crack on either surface, has further bifurcated in to a couple of more cracks extending to the sides. The extents of all these cracks are indicated with red arrows.

Note: This is one tricky stem repair that I would be undertaking. I had half a mind to completely replace this stem with a new one rather than repair it. But I wanted to preserve the originality of the pipe and secondly, I did not have a suitable acrylic stem to match the beauty of the original stem and pipe combo. So repairs to this stem are the way out for me at the moment. The Process
Firstly, I cleaned the stummel exterior with Murphy’s soap and hard bristled tooth brush. I used an abrasive Scotch Brit pad to completely eliminate the lacquer coat from the surface. I diligently worked the rim top surface to remove the minor traces of darkened stains that remained. With a shank brush, I thoroughly cleaned the mortise of all the dust that had accumulated inside and along the mortise walls.

Note: The reddish orange stain on the stummel has reduced significantly, but not completely. I would need to resort to other stronger measures to eliminate the old stain. The rim top is now clean and the lacquer coating from surface has been removed completely. The fills would need to be refreshed. Next, I wiped the stummel with pure acetone on a cotton swab to eliminate the minor reddish orange stain that remained on the surface. The acetone worked well and the stummel is now free of the old stain, presenting me a fresh canvas to work further. Continuing with the stummel refurbishment, I decided to refresh the fills at the back of the stummel. Using a sharp dental tool, I removed the old fills and cleaned the area with a cotton swab and isopropyl alcohol. The gouged out spots were filled with clear CA superglue and set aside for curing.With the stummel fills set aside for curing, it was time to undertake the repairs to the stem. I first cleaned the stem surface with isopropyl alcohol on a cotton swab. Using nose pliers, I gently flexed the crack just enough for the superglue to seep in. I applied a generous layer of clear CA superglue of medium viscosity over the crack and flexed it a couple of times to make sure that the glue had seeped in to the crack. I pressed the crack together in a vice and set it aside for the glue to cure.

Note: The last picture shows that the glue had seeped completely in to the crack and inside the stem opening that houses the tenon. I shall resort to sanding to remove the excess glue from inside the stem.  Once the glue had completely hardened, I applied another coat of superglue over and around the cracks on either surface. I spot filled the tooth indentations in the bite zone with clear CA superglue and set the stem aside for the glue to cure.Next, while the stem fills are curing, I sand the stummel fills with a flat head needle file to achieve a rough match with the rest of the surface. To achieve a better match and also to address the dents/ dings over the stummel surface, I sand the entire stummel surface with a piece of 220 grit sand paper. I also work the rim top surface and inner rim edge with the sandpaper to even out the rim edge. This sanding also helps in removing residual old stain while providing a smooth surface for the next stage which is polishing cycle using complete set of micromesh pads. I was especially very careful while sanding the sides of the shank around the stampings, as it is very easy to miss out the stamp and one swipe of the sand paper is enough to ruin/ damage the stampings. To remove the sanding marks and bring a deeper shine, I polished the stummel with micromesh pads, wet sanding with 1500 to 12000 pads. I wiped the surface with a soft cloth at the end of the micromesh cycle. The shining stummel looks amazing with a deep brown coloration and beautiful Angel’s hair grains popping over the stummel surface. Next, I rub a small quantity of “Before and After Restoration Balm” in to the briar with my finger tips and let it rest for a few minutes. The balm almost immediately works its magic and the briar now has a nice vibrant appearance with the beautiful darkened grain patterns on full display. I further buff it with a horse hair shoe brush. The next afternoon, I work the stem as the fills had hardened nicely. First, with a flat head needle file, I sand the fills in the bite zone to achieve a rough match. I further fine tuned the match by sanding the filled area with a folded piece of 220 grit sand paper pinched between my thumb and forefinger.Next, I sand the excess glue from over and around the crack using a flat head needle file followed by a piece of 220 grit sand paper. I used a round needle file and a rolled piece of 220 grit sandpaper to sand out the excess glue from inside the stem opening for the tenon. I also remove excess glue from within the grooves of the fancy stem.

Note: I was careful to maintain a very thin layer of glue over the cracked surface as it would lend additional support and rigidity to the cracked area. Also, I was extra careful while sanding the inside of the stem opening for the tenon to achieve a smooth and even surface for the seating of the tenon.One of the probable causes for the cracks over the tenon end of the stem could have been a very tight fitting tenon. I lightly sand the smooth end of the Delrin tenon with a folded piece of 220 grit sandpaper to achieve a snug fit (not tight and not very loose) in to the stem opening for the tenon. I frequently checked for the seating as I did not want to open up the cracks again. At this stage I am very pleased with the stem repairs and the seating of the Delrin tenon in to the stem.

Note: While sanding the smooth end of the Delrin tenon, one has to be careful and ensure an even all around sanding of tenon as it directly affects the seating of the tenon in to the mortise and thus the seating of the stem face against the shank.  Next I dry sand the entire stem surface using 600 and 800 grit sand papers followed by wet sanding with 1000 grit sandpaper. This serves to reduce the sanding marks of the more abrasive sand papers. I also sharpened the button edges with the sand papers. I wiped the stem with a cotton swab and alcohol to remove all the oxidation and sanding dust from the surface.I followed up the sanding regime with micromesh polishing to bring a shine on the stem surface. I wet sand the stem with 1500 to 12000 girt micromesh pads. I rub a small quantity of olive oil (though not necessary for acrylic stem) in to the stem surface to hydrate it and set it aside. The stem looks nice and shinning.Now, on to the home stretch!! I very excited to see the result of the final polishing cycle with Blue Diamond and carnauba wax.

To apply the finishing touches, I first mount a cotton cloth buffing wheel on to my hand held rotary tool and apply a coat of Blue Diamond to the stummel and the stem to polish out the minor scratches. With a cotton buffing wheel that I use for carnauba wax, I apply a coat of carnauba wax and continue to work on it till the complete coat of wax had been polished out. I mount a clean cotton cloth buffing wheel and give the entire pipe a once over buff. I finished the restoration by giving the entire pipe a rigorous hand buffing using a microfiber cloth to raise the shine further. The finished pipe looks fantastic, the beauty of which is accentuated by its classic shape, size and hand feel. P.S. The stem repairs are solid and with a little care while handling, this pipe should last a few more decades. This pipe is all set for a new home and is now truly ready for a long hiatus with a new piper, providing years of service in future.
