Banding and Stemming a Figural Pipe – A Carved Bull’s Head


I have never been a big fan of carved animal pipes- whether birds, bulls, horses, etc. There is just something about them that always makes me shy away. Needless to say when I picked up this one in an EBay lot I put it in the bottom of the box of pipes to be refurbished and kept burying it lower in the box. A few weeks ago when I had very few left I decided to give it a go. There were a few challenges about it that made it look interesting. It was without a stem and the shank was damaged – several cracks in it. The angles of the shank made banding it a challenge and the thickness of the neck of the bull at the base of the shank made it formidable. Those attracted me to giving it a try. I also figured I could do some carving on the shank to make it possible to band it and then sand rework an old stem to fit the newly carved shank. The bowl has some kind of impermeable coating on it. Acetone will not cut it; Everclear will not cut it and even a soak in the alcohol bath will not cut it. It is like a coat of Urethane. All my attacks on it resulted in not even damaging the surface. Ah well it will stay as it is then.

I used my Dremel to sand back the shank area so that a band would fit it. I sanded back the neck of the bull to allow for a visible shank. I also had to sand the area at the back of the head to fit the band on the shank. I sanded it with some medium grit emery paper to remove the deep scratches from the Dremel and then worked it over with 240 and 320 grit sandpaper to smooth it out. I finished by wet sanding the shank with micromesh sanding pads from 1500-3200 grit. Once I had it cut back and ready, I heated a band with my heat gun and pressure fit it onto the newly formed shank. The next three photos show the newly banded shank. I left a little excess length on the band so that it would form a seat for the stem (visible in Photo 2). The shank end was so badly damaged that I could not get a smooth end on it. In Photo 3 you can also see the cracks in the shank that I repaired with superglue and pressure.

I had an old stem in my can of stems that was the right shape. It was also in rough shape. It was one of those I had held on to that should have probably been pitched. However, it was right for this shank and would be reparable with a bit of work. This pipe sat on my work table throughout the repairs I was doing on all the other pipes I have worked on in the past month. It was just sitting there and every so often I would pick it up and work on it. The next series of nine photos shows the stem that I was working on for the pipe.

Once I had the stem cleaned up and repaired it was ready to be heated and bent to fit the flow of the pipe. I set up my heat gun and turned it on low heat. I held the stem over the heat at a distance of 2-3 inches and kept it moving back and forth to prevent the vulcanite from burning. When the vulcanite was pliable I used a wooden rolling pin and bent the stem over the curve of the rolling pin. I find that using this keeps the stem from bending at an angle.

I took it back to the work table and began to sand the stem and the shank with a fine grit sanding sponge. I continued to sand it and then worked on the shank with micromesh sanding pads from 3600-12,000 grit to prepare it for restaining.

Once the shank was prepared I stained it with a dark brown aniline stain. I flamed it and repeated the staining and flaming until the brown matched that of the rest of the bowl. I then gave it a coat of Danish Oil medium walnut to seal the shank and give it a shine that would match the head of the bull. I also finished sanding the stem with the remaining grits of micromesh (3600-12,000 grit). When I finished I buffed the stem and shank with White Diamond and gave it all several coats of carnauba wax. The next series of five photos show the finished pipe.

Repairing a Bite Mark on a Kirsten Stem


In one of my EBay bargain basket purchases I picked up a Kirsten Barrel and stem. It is complete minus the bowl. I have a bowl coming from a friend so it was time to do some work on the stem and barrel. The valve on the end of the stem was stuck shut so removed the stem and needle valve system from the barrel and filled the barrel with alcohol up to the top of the valve on the end. This worked through the buildup on the valve and I was able to remove it. The barrel was fairly easy to clean up with alcohol and cotton swabs. The stem valve also cleaned up nicely but the stem was another matter altogether.

ImageImage

On the underside of the stem was a deep bite mark. It was rough around the edges and the vulcanite was compromised. On the top side of the stem were some smaller and less deep bite marks that were more like dents. There was also a wrinkle in the topside of the stem that was strange. The first two photos below show the stem when I began to work on it.

ImageImage

I decided to use my heat gun and set it on the lowest setting and held the stem over the gun to lift the tooth marks as much as possible. The ones on the top side of the stem lifted very easily with the heat. The wrinkle also smoothed out easily with the heat. The bite mark on the underside lifted slightly but it was not going to come out smoothly. I then sanded it with 240 grit sandpaper to remove the remnants of the bite marks and remaining tooth chatter. The top of the stem came out very nicely and I would need to work out the scratches with higher grits of sandpaper and micromesh. The underside was another matter. I sanded out the roughness around the edges of the crater in the stem. I sanded out the remnants of tooth chatter to see what I would have to do to reclaim the stem. The next two photos show the stem after the sanding with the 240 and 320 grit sandpaper. The topside is nice, but the bottom crater remains – smaller but visible.

ImageImage

I sanded the stem with 400 and 600 grit wet dry sandpaper to remove the majority of the scratches pictured above. The top side I then sanded with 1500-2400 grit micromesh sanding pads. The first photo below shows the top of the stem and the bite marks and tooth chatter is gone. The stem from the top looks clean and new – ready for the bowl when it gets here. The second photo shows the underside of the stem. For the crater in the underside I cleaned out the hole with a cotton swab and alcohol. I picked away any debris that had collected in the hole with a dental pick. I then filled the hole with black superglue. I made a superglue bubble over the hole to make sure that when it dried it would be able to be full enough. I set it aside for the night. In the morning I sanded it with 320 grit sandpaper and took the bubble down to the surface of the stem. I then sanded with 400 and 600 wet dry to smooth it out more. Finally I sanded it with the 1500-2400 micromesh sanding pads to get it to the point shown in the second photo below.

ImageImage

At this point the stem is repaired and all that remains is to do some final sanding with the higher grits of micromesh sanding pads. I worked on it with 3200 and 3600 grit micromesh and then polished it Maguiar’s. After that I sanded it with 4000-12,000 grit micromesh and then gave it a coat of Obsidian Oil. The finished stem was buffed with White Diamond and then more carnauba wax. I also hand polished the barrel with carnauba wax.

Repairing a Stem on a Dr. Grabow Grand Duke with Black Superglue


I took on this project to demonstrate how I use black superglue to repair deep bit marks/bite throughs on vulcanite stems. I had this old Grabow stummel in my box and I found a stem that looked good on the bowl. The bowl had a small hairline crack in the shank so I pressure fit a band on it for a repair. The bowl needed to be topped so I did that after banding. I restained the top to match the bowl colour. I used a dark brown aniline stain that I mixed with isopropyl alcohol until I got the match I was looking for. I stained and flamed the rim to set the stain. The stem was in pretty rough shape but I decided to use it anyway and take it on as a project. The button was almost gone from the deep bite marks. There were three bite marks on the underside of the stem near the button and on bite mark on the top of the stem. I decided to use the boiling water trick to try to raise the dents as much as possible. These were deep bite marks and the edges were rough so my guess was that they would not come up to the surface with the heat. I then sanded the surface of the stem with medium grit emery paper to remove the surface marks and dents and then smooth out the area of the deep bite marks. I work to have a semi rough surface for the superglue to bond with so I am not sanding it smooth as much as working it over to make it clean. The next three photos show the state of the stem after I had sanded it and readied for patching.

ImageImageImage

Once I had sanded the surface smooth I used my needle files to recut the sharp edge of the button and rework the flow and angles of the button. I also used the needle files to carve the surface of the stem and provide a gentle slope to the new button area. I have found that often when recutting the button and defining its shape it is easy to cut a trough and make a hump in front of the newly shaped button so I always start about half way up the stem and use the file to change the taper to flow to the edge of the button. This served the dual purpose of removing high spots on the bite marks and to help identify the actual holes that would need to be patched. The next two photos show the file work on the stem.

ImageImage

Once I had the slope correct and the button shaped I put the stem in the ebony block I had drilled with a mortise to allow me to sand the rest of the stem without rounding the shoulders of the stem. I wanted the stem shank junction to be smooth and well fit. I also wanted the oxidation removed from the stem before I patched it with the superglue. I did not want the oxidation to remain in the holes that I would patch or on the surface of the stem. I sanded it down and removed the oxidation. I spent extra time around the bite marks. I also picked out any loose debris in the marks with a dental pick and then wiped it down with alcohol to remove the dust and provide a clean surface for my patch work.

ImageImageImage

The next series of three photos show the patch in place. I use black superglue that I pick up from Stewart-Macdonald http://www.stewmac.com/shop/Glues,_adhesives/Stewart-MacDonald_Super_Glues.html I have found that it really works well. I drip it on the cleaned hole and make a bubble of superglue. This particular glue dries slowly so I do one side of the stem at a time. I let it dry for over an hour before turning it over and doing the same thing on the other side of the stem. Once I have made the patch I set the stem aside to dry overnight. I do not want to touch it or sand it until it has had that time to cure and become hard. I have tried sanding sooner but always end up patching the holes a second time because of my impatience.

ImageImageImage

Once the glue has cured and is hard it forms a small bubble of black on the surface of the stem. I sand the bubble flat to the surface and taper of the stem. I use a 320 grit sandpaper to accomplish this sanding. At this point in the process I am not looking for shininess or polish I am only trying to blend the patch into the surface of the stem. The next five photos show the process of sanding down the bubble and the look of the resulting patch on the stem. The tooth marks are gone and in their place is a black patch that with a bit more polishing and sanding with micromesh will blend into the stem well and give a new polished look and comfortable feel to the stem.

The underside of the stem. Notice the patch near the button after sanding with 320 grit sandpaper. The patch on the underside is larger than the one on top but it not as deep.

The bubble of black superglue on the top of the stem. The white dust on the stem is not a problem as the bubble is dry at this point and ready to sand.

The top side of the stem after the initial sanding of the bubble. It is almost smooth and needs to be wet sanded with the micromesh sanding pads.

The top side of the stem after the patch has been wet sanded with 1800 grit micromesh sanding pads. There are still scratches that remain in the stem on both the top and the bottom that more sanding will remove. The patch will also blend in better as the stem itself begins to shine.

The next series of photos show the stem as I sand it with the various grits of micromesh sanding pads. Between the 2400 and the 3200 grit sanding pad I scrubbed the stem with Maguiar’s Scratch X2.0 to polish out some of the remaining scratches.
