Original Message----- Hey Jon. I asked Ray and here is the answer Dale Erwin R.P.T. Subject: RE: from Jon page on p-tech Stock bore is 2 1/8” bass & 1 13/16 treble. Ray Negron Ronsen Piano Hammer Co. From: Dale Erwin [mailto:erwinspiano at aol.com] Sent: Thursday, February 14, 2013 9:38 AM To: ray at ronsenhammer.com Subject: from Jon page on p-tech 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, Jon Page Dale Erwin R.P.T. Erwin's Piano Restoration Inc.
