Also remember that a larger stepper usually isn't going to be able to go quite as fast as a smaller one.

Hello all again; Those who use the big stack of heavy fender washers, held between rubber washers that fit the hub tightly, on a long drum that holds about a 2" stack of these might be able to comment here. This bigger motor seems quite a bit noisier that the old 252 oz/in motor was, and much of it seems to be coming from the damper, which I haven't adjusted the clamping pressure on the stack for quite a while. Its rattling, and I note that the washers are fairly easy to turn. So obviously as a torsional vibration absorber they are not working at all well. And the mill I believe is being speed restricted because of that. How hard do you folks clamp them up? Is there a generalized rule of thumb, or is it closer to black magic to "get it right"?
