Dean asked: "If epoxy penetrates cracks just as well as CA does, then why don't we use it to treat loose tuning pins?" Dean, Define "..we...". I have used Epoxy to fix bad tuning pin situations. To be honest, I don't like the pin feel, even though it cured the problem, at the time, and continues to maintain. I like the feel of the CA'd pinblock better. I believe it is because the CA gets a whole lot harder in it's set. Epoxy, (depending on each one's specific qualities), sets a lot softer, imo, hence the less than desireable "feel". Besides, CA is the Goop de jour for most these days.<G> It is over used and mis used, imo. Do I use it? Yes, but in very specific situations that I have experimented with, (in my shop), and have found the results to be positive. I do not use it to fix wood joints that are under shear, nor piano parts, except in last ditch efforts on absolute crap pianos. I have used it to reduce falseness in the treble bridges of a few pianos, with mixed results. That one, I'm still on the fence about.<G> As you may recall, I make replacement parts for Odd Pianos, and such. So, I don't want to shoot myself in the foot on that front.<G> CA has it's place, just like all other substances we use. We have to use all of them with a smattering of intelligence and forethought, imo. I like to think "longevity".<G> Best, Joe Joe Garrett, R.P.T. Captain of the Tool Police Squares R I
