Robin Olson RPT Well, one thing NPT stands for is National Pipe Thread, a standard = for threads on pipe, as opposed to threads on machine screws, which are = either metric or S.A.E. (Society of Automotive Engineers). The S.A.E. = standards specify the various sizes of bolts, nuts, threads per inch, = etc. Pianos, of course, have mostly wood screws, but there are a few = machine screws. I can't think of any instances where we'd run into pipe = thread, except possibly on tuning lever tips. Oh, and of course, pipe = clamps. NRP -- I don't know. Non-registered parameters? Not raised to = pitch? No real purpose? Newly re-whatevered piano? =20 --David Nereson, RPT =20 ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
