Ya, I guess I went thru many many v-belts by taking off trying to spin the wheels, with that belt-tightener set-up. The centrifical clutch was like a new invention back then, and seemed like an automative transmission to me.
..and you know I still spend all day (or days) out in the shop fabricating past to this day. I went out in the shop at 10 A.M. yesterday, and didn't come back in the house untill 10 P.M. last night!!! Talk about an obsession!! :?
