I have been thinking the last couple hours about what you two guys wrote. ...I couldn't figure out how the geometry was messed up. (and iI was never too good at geometry)...
Hey Mike...that's why your clutch is messed up, you are applying geometry to a problem that requires physics! :-D
The mechanical clutch is a series of levers and fulcrums. In physics a lever is a rigid object that is used with an appropriate fulcrum or pivot point to either multiply the mechanical force (effort) that can be applied to another object or resistance force (load), or multiply the distance and speed at which the opposite end of the rigid object travels.
All this and I've only had two beers...after a few more and I'll be a friggin Rocket Scientist!
