In years past I remember posting on a variety of pipe forums I have been a part of regarding correcting an overturned stem with a screw mount. I have had old Kaywoodies and others that have this kind of stem and inevitably they were overturned so that the stem did not line up. It was semi tolerable on round stems but even then it was bothersome for me. The worst was on a bulldog with a diamond shank and stem. To not have the diamonds line up just bugged me. I knew there had to be a fix for this but I had no idea what it could be. I used various paper washers to help with the process. I used cardboard and even thin leather. All of these were less than satisfactory. Besides I am a bit anal about that kind of thing and I want it as it should be not half way there.

I don’t remember who posted the help for me or if I picked it up in talking with folks but I have been using this method for a long time now. I have seen others ask on various forums for a method for correcting the problem and have often typed out a response for them. Today I had a few moments to spare so I thought I would write up the procedure and share it with you.

My procedure is actually quite simple. I have a small microwavable bowl that I fill with enough water to cover the metal tenon and about a quarter inch of the stem when it is placed in the bowl. My bowl has a 2 ½ inch diameter so I can lay the stem in it at an angle with the button over the edge. Care should be taken as the water can and will bring out oxidation on the stem and it can be a pain to remove. I try to not allow the water to climb too high on the stem to minimize the work. I also place the stem in with the bend down on a bent stem. Vulcanite has memory and will straighten with heat so I have found that placing the stem with the outer bend in the bowl aids in keeping the bend.

Once the stem is placed in the water I place the bowl in the microwave and set it on high heat for 2 minutes. This generally gets the water boiling or just under boiling. If you worry about the metal causing trouble with your microwave you can heat the water without the stem and stick the stinger/screw mount end in the boiling water once it is removed. Once it is hot I let it stand in the water for another 2 minutes and then reinsert in the shank of the pipe. The glue should be softened enough to turn the stem until it is in the correct position. Once I get it straight I set it aside and let it cool and the fix is finished.

I have used one other method with good success as well and that is a heat gun as the source of the heat. For me it is a bit more labour intensive as you have to keep the stem moving so as not to burn the vulcanite. It does work well though and you do not have to fight the oxidation. Once it is heated use the same procedure as above to straighten the stem and fit. Let cool and you have it finished.

If the stem does not turn easily you have not heated it enough. Give it some more heat with the gun or the water until it is easily turned on the shank. I have used this method on all pipes with the screw mount tenon/stem and had good success.

Because it worked so well with the metal screw mounts I decided to give it a try with a bone screw tenon on a couple of older meerschaum pipes and an old deco Bakelite pipe. The pipes I chose to try the method on were pipes of little value so that if it did not work it would not be a loss. I put a cup of water in the microwave and stood the stem in it tenon down and set the timer for two minutes (time to boil a cuppa in my microwave). I took it out at a minute and gave it a try and it was better. I put it back in the water and let the two minutes finish. I don’t know if the tenon loosened or if it swelled but it is certainly fixed.

On these old timers my two concerns with the microwave were integral damage to the bone tenon from the heat moving from the inside out and secondly to the Bakelite stem. I did not want it to become brittle from the same process. I tried to minimize that by putting it in the water. I have learned on the metal ones to insert the stem and tenon while the water heated in the microwave for maximum effectiveness. I decided to do that as well. I have been smoking these pipes now for several months and taking them apart to clean them without any problems. It seems that they have not been compromised.

I have yet to try it on amber as I have not had an amber stem to sacrifice. I now know that it works on Lucite, vulcanite, Bakelite and on older bone tenons. I continue to experiment with these older pipes to learn what I can in terms of restoration. If you have suggestions or ways in which you have worked with this issue let me know.
