Humm,
why would not a laser set on the string pointing at the rim, first =
measurment on the speaking length and the second reading on the tail =
with the laser pointed at the same target.  Bypass the bridge all =
together.
Just thinkin,

     Some techs do not rebuild but only use them to see if there is any =
residual bearing left in the 90 year old almost flat or flat  board. =
Under those conditions it's difficult to tell anything with the gauge =
because of the bridge slope towards the rear & a sunken crown/bridge as =
well  One gets really funky ideas of whats there &  not there if you =
know what I mean.=20
   As to your useage , yes of course this what they're for. I wasn't =
looking for trick answers. It would be nice if the gauge were fashione =
from cast brass or iron for a more solid seat on the string.

    Dale,
            Uh, I'm not sure what type of an answer your looking for =
here but I'll take a stab at it. I'm needing to set plate height during =
the course of a rebuild and check for down bearing during the course of =
evaluating a piano. Isn't that what their for?

        Thanks Dale. I've been doing just that but I'm not happy with =
the repeatability of measurements. There's just got to be a better way. =
Any other gauges out there? I seem to remember a Journal article with a =
dial gauge of some kind. Am I dreaming?
