I admit to great ignorance on the true basics o= f=20 "false" beats in strings: Some technicians hold as true that the combination= =20 of short string length in relation to an over-large diameter (read short-sho= rt=20 grands) causes the string to subdivide unevenly giving poor results ? Can=20 this mechanism be akin to the "wow"? Really the only way to tell is through=20 experiment. BTW I toured a wire-drawing mill in Michigan last year and the m= ost=20 striking thing was the large amount of heat-treatment tooling, assaying=20 laboratory, and measuring equipment, which brought home how radical the phys= ical change=20 was in the wire as the draw progressed, and the difficulty of holding even a= =20 two or three ten-thousandth tolerance over many miles of wire. One elegant=20 thing they taught me was to use a tenth-reading instrument (I like a dial sn= ap=20 indicator) that you pre-set to a master wire. Makes for less reading difficu= lty=20 since the "feel" ratio is so striking it's obvious when you jump a size !
