I plan to try them on a S&S D this summer. You can tell the correct orientation, as some thoughtful person has put a nice black line on the side that goes bottom down. But it is easy to see on the bench, which is which.   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 action geometry. Perhaps it could use a shallower dip, but I don't want to compromise there if I don't have to. This is a 1940 vintage. Perhaps key dip was shallower?   String height:   Note 62 is post on at 7 5/8"           36 is 7 3/4 (natural crown?)...I've seen the string height drop dramatically here in winter!           1-20 are about 8" (from the middle of the string diameter)   These problems have been discussed this past year, giving me the urge to revisit this action and try to improve it. I did raise up the rear of the stack some a few years ago, but maybe not enough. The distance from the shank to rest felt was way, way to large.   Thanks to the kind souls on this list for publishing Mike Mohr's forefinishing notes. Anyhow, I need to do some more head scratchin'....take a lot of measurements again.   I'm hoping the Wurzen felts will help too!   <st1:place w:st="on"><st1:PlaceName w:st="on">Richard</st1:PlaceName> <st1:PlaceName w:st="on">Adkins</st1:PlaceName> <st1:PlaceName w:st="on">Coe</st1:PlaceName> <st1:PlaceType w:st="on">College</st1:PlaceType></st1:place> <o:p></o:p> </div> </body> </html>
