well i did some more work, but was too busy grinding, cutting, and welding to bother with the camera. :roll: i tossed on the front sprocket and got the jackshaft in place, just need to weld it and weld on the back sprockets. i need to devise a plan though, so that at least one of the sprockets will be removable. i was thinking welding on the base part of an arm for a 3 piece crank, where it attaches to the spindle. does anyone know of any 3 piece crank arms made of steel for the modern square spindle?
