---------------------- multipart/alternative attachment Some pianos should just never be made.... I think these are made in the Chinese Young Chang plant. They look suspiciously like those little 107 jobbers that break jack springs from time to time. First ("free") tuning presented a plethora of problems(Am I almost as allitertive as Alan:-). The hammers were a good half inch off the rail, keys were tight, yada, yada, yada.... The REAL problem was that the keyboard is so poorly weighted that there is so much downweight in the black keys at either end of the keyboard that the action weight and springs can't hoist them back into position, with damper pedal on or off. I didn't take readings, but I could feel huge weight differences from one key to the next. After everything was regulated as well as possible, keys eased, keypins lubed, the jacks still could not force their way back under the butts, despite a healthy dose of teflon powder... I stretched the jack springs to increase tension, though if I had time I'd have replaced them with stronger ones. This seemed to get the thing to function. Short of pulling leads out of the fronts of the keys, any other ideas helping this action? Thanks, Dave S. ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
