Note that while my motor is rated at “2.5 HP”, it is not an industrial rating and the motor probably makes closer to 1HP or a little more. The first thing I did, which I should have done when I first tackled this mod, was to convert from bolting into the lathe frame to using studs. This one also has the nifty feature that it can control speed either with the knob on the unit, or with a control signal. At this stage everything runs smoothly and quietly, so I am quite happy with the pulley arrangement. 90-180V 10A. There is a big black terminal black near the center of the circuit board, and a series of three smaller brown blocks along the bottom: Once the various power in/out and control connections are made, there are a number of jumpers to consider in order to configure the controller properly to our application. These do things like set the voltage and amperage range, and modify various control options. I love Arduino's! Go through until you find a winner. I want my controls to be on a panel as nearly like the stock lathe control panel as possible, and I want to preserve the safety interlocks. These were all recommended by a KB Electronics distributor. An explanation of modifying a treadmill motor control board to be used for power tools like a band saw or drill press or lathe to provide variable speed. Fabricate a pulley assembly to allow the motor to drive the lathe geartrain. Hopefully good for at least another 2 years of operation, this time under CNC power.
