This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Bill, These specs below should let you regulate almost any grand if its parts = are in reasonably good condition. Pay very close attention to the = knuckles for roundness, firmness, and as dirt/graphite free as possible. = Poorly shaped knuckles are a major cause of unstable regulations. Before = you start, make sure you have some spring, drop, and hammer blow = (thickness of shank off the rest block will work) on every note. If all = three are not present, the note will not regulate. Natural key height will be in the vicinity of 2 1/2"; sharps approx. = 1/2" above naturals. Hammer blow will be in the vicinity of 1 3/4" to 1 7/8". Dip will be in the vicinity of 3/8". Let-off will be around 1/16 in the treble, slightly more in the bass. = Best is as close to string as possible without blocking and without = leaving it in potential danger of blocking after you've finished. Drop will be proportionate to let-off. Backcheck height should be as high as possible. Set samples in each section to see which parameters work. Fudge where = necessary only when you understand why/where you are fudging. :-) Once = you find the parameters that work, set the remainder to the samples.
