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.
