Two ways to judge what's an appropriate SW. 1.) whether it's properly matched for the overall action leverage ratio (determined for the most part by the Key ratio and the hammershank knuckle mounting distance). 2.) by sound, for a given situation. There are plenty folks on the list who would like to see a higher #1 SW on a Stwy D. >Also, are friction weights above 10 or 11 too high? Check out David Stanwood's careful explanation of this matter on "Re: Pinning on new flanges" on 8/26/04. Also get use to referring to friction as a force. Weight, the gravitational attraction between two masses, is also a force. Of course the force of friction is in part, a function of the pressure of the contact between two sliding surfaces, and that pressure is a matter (if nothing else, of their gravitational attraction. But friction's final concern is with how smoothly or stickily two surfaces slide against each other, and this should be thought of as a force, not a weight.
