This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment List I recently serviced a U1 vertical for a first time client. Excellent piano very little wear and -tuned up quite well. I did however find lettoff to be over !/4 "and inconsistent. I adjusted to 1/8" -and took up lost motion. Tightened action screws. The key dip and after touch were sufficient, and the jacks are free to travel away from the butts---no interference from that adjustable rail-(sorry, I forget Y's nomenclature on that component) My client has a light touch and the action still stutters I returned, shortened blow distance readjusted lost motion, and adjusted spoons to re-correct damper timing. My client called again with the same problem and called other technicians for advice also I know bobbling hammers can be a problem on Yamaha verticals and I've worked on hundreds of these, but I can't shorten blow any more and as I mentioned, keydip-aftertouch are correct. I'm hesitant to increase lettoff back to its original excessive amount, so esteemed colleagues ---Any suggestions? I'm going back next week. P.S. Backchecks are also adjusted---I.E. catchers are not bouncing out or off of the backchecks Tom Driscoll RPT ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
