I have a customer with a quite new (3-4 years old) Schimmel K120, a nice ~47" Studio. Nice, except that virtually all the tuning pins are barely tight enough to hold pitch, which of course makes it unpleasant to tune. I am in contact with Schimmel about this. They want to send me a set of oversize pins. I suppose anything would be an improvement, but I have a few apprehensions/questions/concerns... (1) I've never re-strung, nor re-pinned, an entire piano. I have replaced single pins here and there, and a dozen or two on an instrument (an S&S "B" that should have been getting rebuilt instead). On the dozen-or-two piano, I had a heck of a time tuning up to pitch when I replaced both pins of one wire. Should I replace one at a time? i.e. pull one pin, (ream/chase... see #2,) replace with new, pull up to pitch, pull other pin, lather rinse repeat? Seems like an incredible amount of tool-changing. (2) There's been much discussion on this list about reaming (chasing) for new pins on a restringing job, and about PDF/resin for driving the new pins. Any opinions as far as either of these topics for repinning a nearly-new piano? (3) For removing the old pins, would backing them out with a power drill generate too much heat? The alternative, manually backing out 200+ pins, seems like an incredible time suck. (4) How much time should I plan on, particularly given this is my first experience?? (5) Would the results be significantly better than CA'ing the block, and worth the effort? I do think that CA'ing a nearly new block sounds like a sacrilege! I do have a tilter which I would think I definitely want to use. Thanks much, Paul Bruesch Stillwater, MN -------------- next part -------------- An HTML attachment was scrubbed...
