IKE: I think that your math might be a bit off. I don't see how a 2" sprocket would turn 360 in*lbs of torque into 1080 lbs of force. In fact, I think that a 2" diameter sprocket would result in 360 lbs of force in the chain. This is still a large number, but not quite as scary as 1080 lbs.

However, Travis has made a number of good points that mean any calculations we do only serve to give an idea of the forces the tensioning system (both the tightening screw and the clamp screws) will see.
