dancing dampers

[dempsey@MARSHALL.EDU]

Brenda,
DON'T be to quick to apply CA glue here. Does this Zimmerman have brass
barrels in the top levers. The ones I have seen (not many, thankfully) did
not. Rather, the damper set screw went into the wood and bears against the
damper wire. Very troublesome. Really tightening the screws risks
splitting the top flange. You should consider either replacing the top
flanges with ones that have the barrel inserts or installing the barrels
in the existing parts.The problem with CA gluing them in place is that at
some point you might want to regulate the back action again....hard work
if the wires won't move.
