After all pins and screws were removed, I pulled up by hand on the top section capo and the plate rocked easily - no feeling whatever of gluing plate to pinblock. The pinblock is well varnished and visually it is hard to tell which splotch was caused by CA and which by water spill. CA which puddled up in tuning pin plate holes just dropped or popped off. To me it confirms my suspicion that - lacking a clean pair of surfaces - use of CA doesn't impact rebuildability. However, the jury is still out until, if and when, I get in a certain diminuitive Schumann into which I applied about 2 oz. That is the scenario Jon was contemplating, I think. It has tuning pin bushings, which I could imagine _could_ be fun to remove, since they would have probably wicked CA right through to the plate and become a solid CA/wood chunk. I and my 1/2" drill could certainly tell torque differences! BTW, almost every pin showed evidence of plate rubbing, bent pins sure are fun to spin out...
