<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> I'm not quite sure what you are saying... by "Most of the U/D weights are in the 16 to 20 difference. However, there are 24 notes that are just way out of spec."  but if you are saying that DW minus UW is in the 16 to 20 gram range except for these 24 notes... then I think it be easier to help if you could put the numbers in terms of BW and Friction. If Balance Weight varies radically, then that points to inconsistancies in ratio related issues. You could be looking at some knuckle allignment problem... not uncommon when a bolstering job is done... and not uncommon otherwise.... Maybe the capstan line is a bit uneven as well... you know the sort of thing. At the stage you are with this job, I like to rule out ratio related problems before attacking friction stuff any further.

I've checked ALL of the pinning, it's in specs. I properly eased all the keys, they're in specs. I buffed the capstans and coated with Emralon. The Wippen Foot Felt and the Let-off Felt has been treated with dry Teflon. The hammers were surfaced. The knuckles were bolstered, strip sanded and treated with Microfine Teflon. The hammers tails were surfaced. The key pins were cleaned, polished and sprayed with dry Teflon. The action has been Regulated to a gnat's eyebrow. Most of the U/D weights are in the 16 to 20 difference. However, there are 24 notes that are just way out of spec. These notes are interspersed through out the whole action. I've checked everything, I can think of, and am at a lose. Feedback would be appreciated!!!! I was up til' 4am finishing this thingee, so I may be missing something! Help! Gotta return the action this afternoon! :-( Best Regards, Joe Garrett, RPT, (Oregon) Captain, Tool Police Squares Are I _______________________________________________ pianotech list info: <a href="https://www.moypiano.com/resources/#archives">https://www.moypiano.com/resources/#archives</a></blockquote> -- Richard Brekne RPT, N.P.T.F.
