Thank you, Jim. That was very helpful. I posted the pic of the Rollag rope drive. We used to have a factory here in Milwaukee that had a rope drive that powered all four floors of machinery. A large corliss engine ran the mill, belted to the rope drive with a leather belt. I got to see a sawmill powered by a rope drive in Alabama. It was conventional, with the rope wheel being the twin cylinder engine's flywheel. I have a video of it and have to dig it out to look at it again. Brad
