I created treadle power for my Craftsman lathe, a simplified version of Roy Underhill’s lathe in Popular Woodworking Oct 2000
There are only 6 boards that comprise the frame. I used stop collars and bronze flange bearings from Amazon. The flywheel is made from one 3×8 board 6 foot long, so it is 2.5 inches thick and 22.5 inches in diameter. And I used a sewing machine leather belt to drive the pulley. The crank arm hole in the flywheel is located 2 inches on center from the axle hole. The crank arm is 12 inches long, with the 2 holes 10 inches apart. The treadle is 30 inches long.
To see a video of it in action:
The second picture shows an extension that I added to make it easy to work the lathe at the extreme right end. It is bolted onto the existing pedal on the left, and on the right it just floats freely on the support.
