I have a number of pipes, so mostly they aren't exposed to intense wear, but eventually, something goes wrong. One of my two Pete B11, bought new and about five years old, came up with a very loose stem. Everything seems to be intact, and it is smokeable, but it is pretty loose and not going to stay in position when heated again, I don't think. My memory of the "fix" on this is to apply bees wax to the part of the stem inserted into the shank to take up the slack space and provide a very mild sort of adhesive. I don't want to gunk the stem up, so I thought I would review this with Forums members before I did it. Alternatives may be suggested, the simpler the better. I want to start with minimal repair, and advance to great measures if needed. There are always good repair people, but I think that might be not be needed for this. Thanks for suggestions. (Note: This happened after an air conditioning repair, so the cooler ambient temperature may have played a role.)
