---------------------- multipart/alternative attachment Loose joint where catcher attaches to butt? ----- Original Message ----- From: Alan To: Pianotech Sent: 3/21/2005 11:57:46 AM Subject: Instructive Challenge of the Day Upright 1890 Kranich & Bach, in very good condition after much work, had a treble hammer that bobbled a bit. 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. 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. Hmmm. 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. 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. No purchase required to enter. Alan R.
