A light tap tightens it, Could this be where the term tuning "hammer" (as opposed to "lever" or "wrench") comes from?

In early writing about tuning methods for harpsichords, the instruction for a pitch standard was: Pull the tension up until you think it might break, then back off a little. That's your pitch standard! Bare in mind that this was long before the time of Hertz. They didn't even have a unit of measure to quantify pitch. In the early 20th c., the harpsichord had all but disappeared from use, until Wanda Landowska revitalized interest in the instrument. When craftsmen took up the task of building such instruments, it was with the attitude that we have learned SO much from piano building over the past century or so, surely we can do a better job of this than they did hundreds of years ago. So, they build harpsichords like Sherman tanks. They didn't look much like harpsichords, and they certainly didn't sound much like harpsichords. Don't fall into that trap. Don't try to beef-it-up. Think of it as a guitar with a keyboard. You may already be blocked into a certain amount of that with a Sabatihl instrument, but you have the opportunity to undo some of it, and restore it to a more "traditional" style of construction. Regarding pin torque, a truly traditional instrument has tapered pins, as others have noted. You have control of the pin torque, as you tune it. A light tap tightens it, and wiggling the pin out a bit loosens it. You can remove the pin to replace a string as often as you like without substantial damage to the block. The idea of zither pins (miniature piano tuning pins) was a bad idea to begin with. Frank Emerson -------------- next part -------------- An HTML attachment was scrubbed...
