This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Upright 1890 Kranich & Bach, in very good condition after much work, had = a treble hammer that bobbled a bit.=20 =20 Checked regulation points, all similar to its neighbors which worked = fine. Held the left pedal down a bit; didn't help. Tried the key with fewer = front rail punchings; no help.=20 =20 Realized the hammer wasn't checking at all. Tried adjusting backcheck; hammer would not check in any position! Made double-sure backcheck was aligned squarely to catcher and that felt and leather were good--same as neighboring notes. =20 Hmmm. =20 Perfectly squaring and aligning the backcheck was what led to the proper diagnosis (hint) but did not improve checking at all. Repair took a = about 30 seconds and did not require turning any screws or any regulating. In = fact, I used no tools at all. Hammer now checks perfectly, wherever I want to = adjust it. =20 Age of piano is a hint, although the problem had nothing to do with the brand of the piano or it's action design which is very "modern," at = least as far as wippens, hammers, and butts go (but don't get me started on it's rocker capstans and short, secondary stickers that are attached with = screws to the capstans). The point is, this problem could occur in ANY upright = but is more likely in an old one. =20 No purchase required to enter.=20 =20 Alan R.
