When I bought my Jet JVM-836 milling machine, I was very happy with the machine, the only drawback was the unit only has 5 spindle speeds (240-1550 rpm). Only 5 speeds and wide gaps between them, was somewhat limiting. I ended up making a "transmission", adding another set of pulleys and a layshaft. I now have 25 speeds, (48-1550 rpm), the step between speeds are very small and there is no vibration. The whole assembly can be removed in about 5 minutes and the machine is back to the original 5 speed configuration. Except for my time, the cost of the aluminum plate, bearings and the set of pulleys was about $120.
