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. 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 Could some explain the purpose of downbearing, how much downbearing where? I and others I'm sure, have measured many a great sounding piano-even new ones-that had almost no down bearing, or even negative downbearing. Is there a text/book that describes such elements of piano construction? Maybe I'm standing too close to the trees to see the woods.
