[pianotech] Lowering the stack on a Steinway

[John Ross]

Why would you cut felt on it? I would imagine it would dull your rotary cutter.
I use a composition sheet that is 'healable' to cuts, made for the purpose of cutting.
Any tabletop or bench is flat enough.

The stack could be set on something like this, checked for wobble and under-feet gaps, and errantly tall feet filed down until all level, non? ( I generally use this for cutting felt strips on, and for gluing operations where an easy-to-clean surface is a help. For the felt cutting operation, by the way, I use the cheap strips of vinyl base-board molding available at home improvement centers --- at about $2 each --- with an aluminum straight edge clamped across everything, and the wheel type cutter.)
