What methods do you use to "tighten up" the fit of you shafts with wood threads(3/8-10 and 3/8-11) as they slowly loosen up a bit. It seems, in my unreliable memory, that Tim Scruggs once told me to swab the wooden threads with a slightly moistened q-tip and allow to dry.That causes the wood threads to swell a bit.Any other thoughts?
