[pianotech] 1098 Hammer Bore

[Jon Page]

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.
