Looking at the pictures, my “guess” is that there needs to be a ridged link between the treadle and the outer most gear ( I know – duh!”) that swivels on both ends. This then pulls the gear forward to spin the lathe, and also allows the gear to be pushed back to it’s original position to start another pull on the lathe while it spins.

I think you will need to drill the gear to accept a swivel pin, same for the treadle, maybe use a bolt, and for a rod use something with a loop on each end. I think that a piece of coat hanger wire could be fashoned to do the job.

To check my speculations, pull the gear forward and push it back as if connected to the treadle, see if I am even close to correct.

Good luck.

PS, nice find, this will be fun to use. Post your first project from it.

Yep. That’s exactly how it works. A few days ago I tightened the nut in the center of the gears, and the gear started working as expected. I’ll play with it some more when the weather warms up (0 degrees this morning, and it’s only December).

Nice idea for the gearing Elroy. Maybe go to a bicycle shop and show them the pictures and video and see if they have any suggestions?

can’t see the video anymore, it seems.

Another possible solution is a chain attached to the treadle peddle, around one of the gears, and then fastened to a spring mechanism (torsion spring, or extension spring) on the treadle somewhere

It’s how many of the Barnes treadle table saws work

Mos, you may have hit on the original design that was intended! The treadle is wide enough to attach a chain to the front and back, and it already has a torsion spring attached below it. I’ve got some old bicycles in our barn that I can scavenge chains from. I’ll give that a try. Thanks!

I would be interested in seeing it, if it works out :) (or even if it doesn’t, I’m just interested lol)

It worked! I cut a chain off from an old bike in our barn, and tacked it in place on both sides of the treadle to test it. Now that I know it works, I’ll fix a more permanent solution.
