I have a pipe repair question. I have a Ferndown Rhodesian that I love. Its mortis, however, is about 1/4 inch longer than the tenon, resulting in a large gap in the stem where really nasty, gooey moisture collects. Can this be remedied? I was thinking of just taking some wood putty and filling the gap with it, but I wonder if there's a "right way" and a "wrong way" to fix this issue?
