First, remove the stem from the pipe and insert a pipe cleaner into the stem so that it just reaches the end of the tenon (this is to ensure that you don't collapse the air hole). Next, carefully heat the tenon over a match for about five seconds (the intent is to soften the vulcanite, not melt it). Then gently press the end of the tenon against a flat surface, keeping the tenon as perpendicular to the surface as possible, taking care not bend the tenon to one side or the other. After the stem has cooled, test fit it. If the stem is still too loose, repeat this procedure. If it is now too tight, then see "What should I do with a stem that's too tight?" below. NOTE: It is *very* easy to ruin a perfectly good pipe with this technique, and I feel I should reiterate my earlier statement that this job is best undertaken by a "professional." | First, remove the stem from the pipe and insert a pipe cleaner into the stem so that it just reaches the end of the tenon (this is to ensure that you don't collapse the air hole).

A variation on the above that has less chance of bending or ruining the tenon is the following: Insert a tapered mandrel into the tenon. Apply heat to the mandrel (an alcohol flame is recommended). As the heat from the mandrel transfers to the tenon and softens it, move the mandrel further into the tenon. Repeat as necessary to get the desired expansion. Remove the mandrel and place tenon in cold water to set. Note that [http://pimopipecraft.com/tools.html PIMO]makes a 'Stem Tightening Kit' that uses this principle. | |||
A less radical (and *much* safer) procedure that has been recommended to me by several people is to simply rub the stem's tenon against a block of beeswax until the tenon is well coated. Once this is complete, reinsert the stem. I am told that the joint will tighten after a smoke or two. | A less radical (and *much* safer) procedure that has been recommended to me by several people is to simply rub the stem's tenon against a block of beeswax until the tenon is well coated.
