Eric Krewson said:I think the problem can probably be summed up in one word, "Accuglass".
This would be my concern based on this thread.
My suspicion is the barrel pins have a glob of accuglass firmly bedded to the pin or the pins have accuglass bedded on each side of the barrel lug. In that case you might be able to drive the glob through the lug but I suspect the glob on the other side will tear the wood as it exits.
It seems like a real puzzle to remedy.
