Hello fellow MMD'ers, I searched the MMD Archives, but did not find
any reference to "Asbestos". I know that the earlier vacuum motors
from PPCo had an asbestos shield around the brush end of the motor in
their vacuum pumps, made from paper sheet type asbestos.
My question is, what obligation is the player repairman under if he
services a piano with this material in the vacuum pump, or has to
service the motor itself? As hot air is passing over this material and
then is exhausted into the air, how great is the chance of fibers being
discharged into the room?
I have that dilemma now, and have decided to replace it with a modern
fireproofing substitute, a thin fiberglass mat. Other opinions?
