After waiting far to long I introduce a much more robust drive pulley system to the MAXNC cnc mill. I used a Ø2.5" drive pulley, and a Ø1.25" spindle pulley. With the treadmill motor's variable speed controller the mill can now run at a max of 10k rpm down to I imagine 2k rpm. I want to try experimenting with a low rpm fly cutter in the future. At the end we tried milling a 1/2" wide by 1/2" deep slot in a Ø2.5" piece of brass. It certainly shook the machine to it's foundations. I need to go through the whole machine and apply loctite to the threads of all the ways screws, and spindle tightening bolts.
