Nevertheless, if you are determined to do this yourself, you must first determine what sort of stem you have. If the stem is lucite, the easiest fix is to apply a very thin layer of clear nail polish to the tenon, allow this to dry *partially *, and then carefully sand the tenon to fit. A vulcanite stem, on the other hand, is a bit more complicated, as you will need to heat the tenon and expand it in some way. There are a number of variations to this procedure, but the most common one is described below.

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 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* difficult  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 "chimp ."

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.
