Pinblock Plugs

[Farrell]

No, I suppose it is not a "fit". But it was the way I did it. I may not do
it again. I don't know that it is the best way to do it. I don't know that
it is a bad way to do it. A tighter fit would use less material. I was
experimenting and the little bit bigger gap allowed the thick epoxy mixture
to ooze back out the top. A tighter fit did not allow the thickened epoxy to
work its way out the top. I posted it more to make a statement about epoxy
and gap filling. The pinblock was solid as a rock (or at least rock maple).
And that is what epoxy does best - you can make a very high strength
gap-filling bond between wooden parts.
