A friend of mine has a home built table saw. This reminds me of the way that works. Very similar

The Drive wheel has a slight crown, the contact wheel is flat. The belt tracking was not a big issue. I just tapped (left-right) the arm around with a hammer til I found then sweet spot the tighted the big wing nut.

I have found that if I press hard and lose tension the belt will slip off, but if I use a light touch it works fine.

I will have to make more contact wheels and think about building version 2 now that I know the idea works.

What size is your motor, and what is the rpm?

Your tension issue could be solved by adding a third, fixed, wheel as the contact point then your current one becomes just a tension arm that might allow you to use a little more pressure if you want to.

It is a 1725rpm motor, I think it is a 1/4 horse but I am not sure.

That is what I will do on the next version, a really good idea.

This one was quick and dirty just to see if it would work.

Fantastic. I had some wandering curiousity about having my own regrinding setup, but put it off as I really had no idea where to start and not much experience. Now that I can see a nice DIY one, I hope to at some point give 'er a go.

I am taking notes as I type this. A friend had his washing machine go belly up but he assures me that the motor is good. I've got the motor now, and a bit of work ahead of me but your post gives me hope.

Are you also able to convert it to accomodate a buffling wheel?

Forgive my ignorance but just how do you use the belt sander to polish a blade ?

Where on the belt and in what kind of orientations do you hold the blade ?

Cheers
