I rather think that some serious absorbtion would have to be going on for that to be a real concern. Course we cant actually look inside the hole with the pin in there to see.... but on the other hand, pins so treated dont exhibit the same kind of falseness this proceedure porports to cure for very long periods of time. In fact, I have yet to see this treatment fail over time, and I have seen mere pin replacement fail quite often. > > > > As will every thing... practice makes perfect and you get the hang > of how to > > accomplish this one successfully fairly easy.

We are talking more of an alternative method of making for a tight fit for the pin. I dont use epoxy in bridge pin holes because I want to glue anything together. I use it to make sure the pin is as solidly snug and supported as is possible. It also seems to do a nice job of counteracting the effects of changing climates on the bridge pin holes, as I dont see these showing signs of hole expansion through the years. Seems to be less of those small cracks out from the pin that seem to always go nearly perpendicular and slightly downwards from the string plane, but that might be a biased perspective on my part... sometimes hard to tell about that kind of thing :) Cheers RicB -- Richard Brekne RPT, N.P.T.F.
