Captian john, that would work, but the engine I am converting is a homelite 33 out of a chainsaw and the crankshaft is only 1&1/2 inches long (very short compared to yours) with only the last 1/2 inch being threaded, thats why I am leaning towards a one piece propshaft with a taper to match the crank as that would give additional support; anyone have any other ideas ?
