[pianotech] Downbearing question

[William Truitt]

HI Al:

 

I check bearing with a dial guage also, amongst other things.  The readings
you are getting I would consider to be "normal" values in a Steinway (is
there such a thing as normal in a Steinway any more?); usually these values
will increase in the top treble section to .020 to .030.

I never got a response to this question. Did my email get through?

I am restringing a Steinway M. Before I pulled the strings I read a
composite down bearing of 10 to 12 thousandths across the bass and tenor
bridges with a dial gauge micrometer. My question is, how much downbearing
is too much.  Is 10 to 12 thousandths too much. At what point would it be
worth pulling the plate to adjust it. The soundboard and bridges are in good
condition.
