Looking for leads on a reference work to help in regulating a Miller square from the 1870-early 80's. Trying to resolve these questions: 1 Are the shanks supposed to rest on the felt, like an upright, with minimal lost motion? 2 With the single escapement, will repetition only occur if key returns to rest before a second blow? 3 I see provisions to adjust hammer height. With reasonable hammer reshaping, raise shanks, retain original blow, and raise rest rail( or add felt)? 4 action centers appear to be brass. Reuse center pins and deal with felt as necessary? 5 Dip will be what is necessary, but appears to be between 1/4"-5/16"? 6 I don't see a mechanical reason to create aftertouch...correct? 7 lacking a rep lever,rep spring and secondary escapement, what is the purpose of backcheck? Doesn't it just create miles of lost motion? Jim Ialeggio -- Jim Ialeggio jim at grandpianosolutions.com (978) 425-9026 Shirley, MA
