Thanks Sunset, I have decided to get a smaller pulley for the motor shaft and a larger one for the countershaft before the step pulley. I would be happy to have my lowest speed be around 60-70rpm, I think that would allow me to use all the size cutters I own in mild steel which is my goal for this conversion.
QUESTION: I have two options as far as I can see, make the entire countershaft assembly rotate on it's base to tension the mail drive belt or use a wide idler pulley to put tension on the mail drive belt. Most countershafts I have seen don't make use of a idler pulley, is there a reason for this? To me it would seem like having the countershaft assembly as ridgid as possible would transfer less vibration to the machine? Thoughts or suggestions are greatly welcome.
