Pinblock Plugs

[Farrell]

I'll be stringing it in a few weeks. Just stained the case parts last
weekend. I have absolutely no fear of any movement. When West System epoxy
is used properly, it is sooooooo strong. The epoxy and the epoxy-wood bond
is much stronger than the maple - especially when the strength-enhancing
fillers are used. Again, I am not advocating the manner in which I plugged
this particular block - just making a statement about epoxy & fillers &
gaps.
