Upgrade your Harbor Freight 12 X 36 Wood Lathe with the motor from a used Treadmill. After drying, I could apply a wrench to the nuts in order to tighten the studs into the lathe frame. Figure your max desired spindle rpm and divide it by 1.2 for a decent estimate of what maximum speed you’ll need from your motor. 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 motor was supposedly rated at 3/4 horsepower, but those in the know say it's really more like 1/3 horsepower).I remembered that I've seen videos of how other people have used Treadmill Motors on other power equipment, so why not try to put one on the lathe? One motor was rated at 2.0 horsepower, and the other at 1.8 horsepower.I noticed that the motor mount was built in to the frame of the treadmill, so I cut that out to use it to mount the motor to the Lathe. It fit very nicely on the motor controller. Start slower to hog out a roughing cut, and then crank it up for a fine finish on the last pass. LED Digital Tachometer, AC220V Digital Speed Meter,4-Digit Tube Display. Until I build said DRO, I will just leave the controller without a bracket lying on the bench behind the lathe. 1/2-2HP. 4000 seemed a bit much, so I scaled that back a bit too. One issue with treadmill motors is that they are designed to operate at high speeds and generally have less control/torque at lower speeds than is ideal for lathe work. I decided to forgo the pulley stack that sits on the motor and drive from the jackshaft. 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. on Step 8. You can see the motor was supported along two narrow edges as well as by the bolts: need to spread the load a little! The picture shows how to do the wiring. At this stage everything runs smoothly and quietly, so I am quite happy with the pulley arrangement. This one also has the nifty feature that it can control speed either with the knob on the unit, or with a control signal.

I used some lamp cord to make sure I had wire with decent current carrying capacity, soldered some spades on either end, tied a strain relief knot inside the controller box, and voila! Also note the speed range on the motor you’re looking at. Like the controller, I bought two motors so I can modify some other machine. Power tools such as Metal cutting mills and lathes, Drill presses, bandsaws, sanders and more may require .5HP to 2HP motors with the ability to fine tune the speed while maintaining torque. Voltage is obviously okay. eBay: $35.00. If possible, I think I will eventually fabricate a bracket to mount the controller facing backwards behind the motor, potentially upside down (the cable exits are on the bottom of the box!). Most of these lathes get down close to 1:1 (usually 1:1.2) on their pulley arrangements. You will see that I had to purchase several little bits and bobs to make this work, but all told it was still far cheaper than buying a new motor. Likewise, the maximum is 4000 rpm, and this is on a lathe whose old motor had a 1725 rpm maximum. For motors rated 1/50 - 3/4 Hp at 180 VDC use Model KBWM-240.
