This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hi Joe, You would have to move the side supports closer to the plunger on = David's gauge, so that they are spaced the width of the bridge or less. = For instance, just make a base that has supports 1/2" on each side of = the plunger. Place the plunger on the string just adjacent to a bridge = pin. Then use these formulas: A =3D angle of deflection d =3D deflection A =3D d / .00437 d =3D A * .00437 You can also use the depth plunger on a small pair of digital calipers. = Make a "base" for the thing similar to David's, except with 1/2" = spacing. Zero the scale, then measure. The value will be negative, but = that's OK. Peace, Sarah ----- Original Message -----=20 From: Joe Garrett=20 To: pianotech=20 Sent: Wednesday, July 06, 2005 2:41 AM Subject: Re: Reading a dial gauge Hmmm? all very interesting, indeed!=20 NOW, how's about the possibility of measuring the front angle and the = back angle???? It seems logical that one could run the center foot of = the gauge to the front pin, leaving the back foot at the back bridge pin = and the front foot all the way out on the speaking length. Reverse this = and you get another reading off the back scale. Is this a feasible way = to calc both of those angles? Inquiring minds want to know!!!<G> OR: perhaps put the plunger at one end, 1" from the two solid feet, = 1" apart that both sit on the flat of the bridge? Hmmm? (as the king of = siam said: "is a puzzlement!"<G>) Regards, Joe Garrett, R.P.T.
