This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Thanks Mark, I don't mean to alarm anyone, I'm hoping there is a simple solution and not a major problem here, too. I know the players at this piano and I don't believe there is heavy playing. Two broken strings in a month and when I first saw the piano the hammers were hitting the V-bar at C8 (dead). I'm still waiting to hear from tech support after talking to two other people who passed me around. I'll keep you posted.

I just can't believe this (the problem you describe) would happen in a new Mason...say it ain't so! For Pete's sake, they're only producing two models of grands (currently), you'd think they'd have the jigs right, especially when you see the size of plate-location pins they use! In any case, the factory should be able to provide you with speaking length at #88 for a quick reference. I don't want to send you on a goose-chase Lance, but often find it useful to look at a problem from more than one angle. Best of luck!

I'll study it closer to see if I can tell exactly what's hitting back there.

Also, tails may hit whippen flanges when hammer comes to rest. I just worked on a 2001 M&H BB and the hammer line was so off, if you pushed the action in for proper strike @ C8 the back checks interfere with sostenuto and under levers, no matter what. The piano is also breaking strings at the V bar and I suspect the hammer line has something to do with it. Regards, Lance Lafargue, RPT LAFARGUE PIANOS New Orleans Chapter, PTG 985.72P.IANO llafargue@charter.net Lance In that case I see nothing wrong with using a motortool drum sander to hollow out the back of the backcheck. Some new backcheck replacement I've used for stwy's have this featire which is helpful when installing modern type back action In an old stwy with minimal clearances. This might give you enough room to move the action to its proper location. What do you think? Dale Erwins Pianos Restorations 4721 Parker Rd.
