David was commenting on how crucial it is to get a good adjustment on the jack position for good regulation. I was hoping for a procedure that was more exact than a visual alignment on the section ends, draw a thread across the section, align the rest of the jacks to the thread.</FONT></SPAN></BLOCKQUOTE></DIV> <DIV><FONT face="Bookman Old Style">My apologies, Dean, you are of course correct. That was Phil Ryan's question originally; I just elided your question right into his. I'll pay more attention. That said, I adjust the adjustable ones quickly by sight, to the back of the knuckle core of the adjacent wippen; or by the line on the top of the wippen if it's close to the right place. You can also rough it in with the string method. Then I adjust by function, bringing each closer to me until just before it fails (Orchestra member: "When do I come in?" Conductor: "Just listen for the trombones, and come in six measures before they do"). </FONT></DIV> <DIV><FONT face="Bookman Old Style"></FONT> </DIV> <DIV><FONT face="Bookman Old Style">Failure I test by placing my hand lightly on top of the hammer, then poking the key. If the jack skips out, it's too far proximal. I agree that it's an important adjustment - if they're too far distal, letoff is mushy.</FONT></DIV> <DIV><FONT face="Bookman Old Style"></FONT> </DIV> <DIV><FONT face="Bookman Old Style">Ed Foote's method might be more refined yet, but this works for me.</FONT></DIV> <DIV><FONT face="Bookman Old Style"></FONT> </DIV> <DIV><FONT face="Bookman Old Style">Bob Davis</FONT></DIV></BODY></HTML>
