And that at "half stroke" the key would be level. If the key is tilted too high, at rest, then the moment of maximum efficiency would happen at let-off, which would be the least efficienct, IMO. If the opposite were the case, the efficiency would also suffer, IMO. Just my musings for the moment.</DIV> <DIV>Regards,</DIV> <DIV> </DIV> <DIV>Joe Garrett, R.P.T.
