[pianotech] 1098 Hammer Bore

[Greg Newell]

Jon,
	Although it's a bunch more work, I would plug and re-drill. Who
cares what the stock bore is? Don't you measure from the string to center
pin and subtract the blow distance? I thought that was it. Please correct me
if I'm wrong.

Best,

Greg Newell

Subject: [pianotech] 1098 Hammer Bore

I was handed a project that another tech could not finish due to a family
illness. New hammers are in the offing but I have a few concerns. 
First, the shanks mic .210" but the hammers were bored to .218" (7/32). 
That is way too loose. Could a paper shim be glued in on the non-string side
of the molding without causing a problem down the line? Secondly, the
hammers are bored close to the same length as these old, worn ones and there
are shims under the hammer rail already. What is a stock bore 
for a S&S 1098?   Maybe I should plug these holes and rebore to bring 
the action parameters to original specs.

Regards,
