<p><br>Hmm... 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.

thing to keep in mind with epoxy - it relies on a mechanical bond between
wood and epoxy and between metal and epoxy. It is recommended by West System
that when bonding with epoxy to metal that the metal surface be sanded
rough, coated with thin epoxy, and the epoxy sanded into the metal for
the most secure bond. A nice new shiny bridge pin is not likely to establish
a good bond to epoxy. I can chip epoxy off any glossy surface real easy
when I get waste on it - my floor, table top, etc.</font> <font color="#800080">Terry

<p><br>Yes, well we are not talking about bonding here. 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 :)
