I was wondering what speed to run the cylinder on my F for corn. My book lists maize (corn ?) at 800 RPM. My machine had 2 sheaves with it when I got it... a small one for wheat 908-1300 RPM and the big one 387-590 RPM. It never had the mid sized one. Will the big one do a satisfactory job at 590 RPM's ? Also, what concave clearance/ speed does the best?
Thanks in advance.
