Silly me, I realized this morning that the dip has to be in hundredths, not thousandths. Oh well, you know what I meant. Ken, your response about Steinway switching the knuckle geometry, yes I realize they changed in '84, I thought the higher leverage shank would yield less dip needed... so I have to rethink this. So if differences in shanks don't account for the difference between NY and Hamburg recommended dip, is the .42 because of key ratio variation? (And therefore will change again as soon as they complete the "2 to 1" program to preset key ratio prior to strike point?) Is that why Hamburgs come out with better projection on Stanwood's charts, primarily? key ratio producing more efficient strike ratios? Audrey Karabinus, Seattle
