Hi Patrick, If the brass flanges are the kind I'm thinking of, the wobbliness is probably not from the pinning it is from the brass flange itself. I believe (and correct me if I'm wrong, you lurkers out there) this type of set is called a Billings action. Those flanges have a tendancy to weaken, by bending the flange back and forth. Eventually it breaks. I try to head it off at the pass by repairing it with the kit designed for this action. Basicly the kit is a new screw slightly longer than the original and another piece of brass used to support the back side of the flange. I have this type of action in my own piano and so far no breaks yet. Although I do get in there every once in a while and fix a few more. Mike Bratcher
