C88 Hammer Position

[Mike and Jane Spalding]

Terry,

1/8 is a good starting point, it probably won't end up far from there.
You're right about hanging a hammer and testing / fine tuning the strike
point.  I wouldn't mount it on the low side, I'd put right where I thought
it was going to belong.  There should be threaded supports for the action
brackets that let you adjust up and down.  It's a good idea to hang a couple
of additional hammers, bottom and middle of the high treble section, and
make sure that when C88 is right, the other two are not wrong.  Hopefully,
this is not one of those uprights where the hammer line wanders away from a
straight line in the tenor?

Mike
