name of grand piano part

[Jim Coleman, Sr.]

Hi Richard:

When I was at Baldwin, we then called it the Bass Stop block. It always has
to be custom sized. I suppose that is why it is not listed as a standard
part by supply houses.

Since Grand pianos are shipped on their sides, this action cloth on the Bass
stop block may get compressed so that it will require veneer or cardboard
shims to relocate the action properly. This procedure sure saves a lot on
hammer spacing time and re-alignment of wippens to knuckles, etc. when one
corrects the source of a problem instead of just the symptom.
