Dick, what I wrote was actual visual experience. course that don't mean anything to you. By the way read your crank thing. most of the quality cranks i ever saw were 3 piece machined from forgings, and they were not cantilever ether. won't get into any thing over it tho. But sounds to me that engine makers that support a crank at both ends might jist know more than any of us modelers. otherwise we'd all make them.
