The way I figured the problem out was to switch out some parts with parts I had on hand that I knew what they were. When I put an original teflon bushed wippen in there, the action regulated like it ought to (shanks weren't resting on the wip cushion) and the down weight dropped to the low 50s. So I figured from that that the shanks were pre-84. I tried a brand new prehung NY IMP shank on the adjacent rep and the dw dropped into the mid 50s and also regulated well. That told me the reps were Hamburg.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>If you have another S&S that works, just switch out parts for one unison and see if there's any improvement before you go reinventing the thing. A couple of clues will help. If the jack is regulated forward of the line on the rep lever and jams into the cushion, that's a big clue. You might also find the shanks laying on or very close to the rep cushions. When you change the parts out, if you have to turn the capstan one way or the other a LOT to get the hammer in line, that's another.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Just wanted to point out that somebody else before you could have made a boo boo. We had the same problem with some rebuilt actions over at UGA (though at the time I didn't know how to identify it), so I figure there had to have been some communication problems with S&S during those days.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Jeff</DIV><BR><BR><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><DIV>Jeff Tanner, RPT</DIV><DIV>University of South Carolina</DIV><DIV><BR class="khtml-block-placeholder"></DIV><BR class="Apple-interchange-newline"></SPAN> </DIV><BR></BODY></HTML>
