Homemade Lathe

by woodyoushouldyou

I found a squirrel cage fan on the side of the road in my neighborhood and harvested the 1/2 horsepower motor to build a lathe. The design is very primitive, it’s basically just a spinning shaft with a piece of plywood on the end. My tool rest is usually just a 2×4 screwed down to the workbench.

photo (29) The motor runs at 1725 rpm so i reduced the speed by half with a belt drive to the main shaft. I attached the faceplate by screwing together two pieces of plywood, one on either side of the pulley.

I used a lag screw to tension the belt to reduce vibration.

To keep the shaft from slipping back and forth, I cut a groove into the shaft (by turning on the lathe and holding the hacksaw against the shaft) and inserted an aluminum plate.

The power cord was cut off at about three feet and it was pretty torn up where it entered the motor so it needed to be replaced. There was a threaded hole in the motor casing so I cut a thread on a piece of pvc pipe, and ran the new cord through that, to reinforce the connection to the motor.
