Treadmill Motor for Taig Lathe : 3 Steps Instructables

Having fabricated the table and the pulleys, I disassembled the original setup. I installed the lathe onto the new table with the four steel stand-off pillars and affixed the motor onto the motor mounting board. The clearance provided allows me to clean out chips very easily, and a lot of room to wrap my fingers around the cross slide dial handles.
