Sorry, didn't finish. Probably about 60 lbs is minimum but on a new piano you'd like to see around 90 - 120 but there is quite a range.

What kind of pianos, what is the torque (if you know), when you say difficult to set do you mean that minimal back pressure causes the pins to move or are they flagpolling? There is no industry standard as the pinblock material and pinblock drilling practices will cause a wide range of torque readings.

Dear members: I have recently purchased several new pianos and discovered during the initial tunings what I believe to be minimal tuning pin torque. The pins feel "spongy" and difficult to set. Is there an industry standard for pin torque, and if so, what should that torque value be in inch pounds? Any data on this subject would be greatly appreciated.
