When setting the gram resistance of on underlevers, what is the best
point at which to take the measurement.  The higher you lift the lever,
of course, the greater the resistance, so where in the travel should the
reading be taken?

David, If you are trying to "gauge" the underlever when it is in the =
piano.....NOT! Gram resistance should be taken on the flange, as with =
the underlever out of the piano!The listed, (Steinway), resistances are: =
Lever Flange: 3-6, (I prefer 3-5); Top Flange: 1-3These numbers are from =
the OLDE Steinway Service Manual, so they pertain to older Steinways. If =
the flanges you are checking are Teflon or Graphite impregnated, then =
all bets are off.<G>Best RegardsJoe Garrett, R.P.T.
