Simple treadle lathe power for Craftsman lathe

I created treadle power for my Craftsman lathe, a simplified version of Roy Underhill’s lathe in Popular Woodworking Oct 2000
http://www.popularwoodworking.com/woodworking-blogs/chris-schwarz-blog/foot-powered-lathe-and-scrollsaw

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.

I could never do that—it’s kind of like patting your belly and rubbing your head at the same time.

What rpm’s can be generated? Obviously it works.

Great idea, well executed also. As long as you have light you can work with no power

Very environmentally friendly.
Now you need a little generator and you are set for lights and some tunes .
Great stuff .

Very cool idea! I just happen to have a lathe just like that standing in the corner not being used, may I’ll copy your idea.

Hi John, I am not sure about the rpm’s, I guess it is limited by how fast you can pump it!

Great, simple design. I love it and want to build one. What model lathe is that? Is it available without a motor?

Hi Dave, I don’t know the model, but you can find them on Craigslist, I got mine for $100. The electric motor works but I just set it aside.

I so want to build something like this! I will have to check Craigslist for some lathe parts.
Thanks for sharing.
Well done.

Hi. I have a couple of questions: I’ve seen other videos of treadle lathes and I believe yours; the wheel is spinning in the right direction? Other, and probably most important for what i want to learn is How do you decide the dimensions and angles of the components from the wheel to the pedal; because again, it looks different than others and I kind of like what I see here.

I don’t think the dimensions are very critical. I mounted the wheel as low as possible, and the treadle mounting point is just a couple inches away from the center of the wheel. I just put it together and it worked fine the first time, but my plan was to just drill more holes and remount components in different places if needed.

Speed can be increased with gear drive and heavier wheel.
