Hi Kevin, That is why I stress leaving over night to dry. One drop per bushing does the Job. If you start to heat the bushing after wetting then the shrinking is toooooo aggressive. I am not a fan for shrinking hammer flanges, my prefference is to repin, since it has such a big effect on tone. In my area I like 4 to 5 swings, more humid climates 6 swings will give a safety margin. Having said that, I have used rubbing alcohol neat, and it works. The good thing about rubbing alcohol, it's availiable at any drug store, and supermarket. Regards Roger At 07:21 PM 9/24/01 -0700, you wrote: > Gee, Roger.
