I plan</DIV> <DIV>to try them on a S&S D this summer. You can tell the correct orientation, as some thoughtful</DIV> <DIV>person has put a nice black line on the side that goes bottom down. But it is easy to see on the</DIV> <DIV>bench, which is which.</DIV> <DIV> </DIV> <DIV>On this S&S D w/.400" key dip, the jack touches the felt in the jack (fly) window. I'll be checking the entire</DIV> <DIV>action geometry. Perhaps it could use a shallower dip, but I don't want to compromise there if I don't have</DIV> <DIV>to. This is a 1940 vintage. Perhaps key dip was shallower? </DIV> <DIV> </DIV> <DIV>String height:</DIV> <DIV> </DIV> <DIV>Note 62 is post on at 7 5/8"</DIV> <DIV> </DIV> <DIV>        36 is 7 3/4 (natural crown?)...I've seen the string height drop dramatically here in winter!</DIV> <DIV> </DIV> <DIV>        1-20 are about 8" (from the middle of the string diameter)</DIV> <DIV> </DIV> <DIV>These problems have been discussed this past year, giving me the urge to revisit this action</DIV> <DIV>and try to improve it. I did raise up the rear of the stack some a few years ago, but maybe</DIV> <DIV>not enough. The distance from the shank to rest felt was way, way to large.</DIV> <DIV> </DIV> <DIV> <DIV>Thanks to the kind souls on this list for publishing Mike Mohr's forefinishing notes.</DIV></DIV> <DIV>Anyhow, I need to do some more head scratchin'....take a lot of measurements again.</DIV> <DIV> </DIV> <DIV>I'm hoping the Wurzen felts will help too!</DIV> <DIV> </DIV> <DIV>Richard Adkins</DIV> <DIV>Coe College</DIV></BODY></HTML>
