[pianotech] Square Grand Hammer Bore Length?

[Joseph Garrett]

Terry,
Tell Ray the make of the piano and he probably has a "Scale" for those. He
bailed me out with a similar situation on a Fischer square. The hammers
were Great!!! The Fischer had hammers, (Regular Grand), installed. The
moron didn't even shape the tails and had the sharp edge cutting into the
backchecks.....hmmmm? could have been the same group of Six-year-olds, come
to think of it.<G>
Ray is Da Man when it comes to this sort of stuff!
Joe
