A used contractor table saw could be an inexpensive source for a donor motor….

hmm..hadn’t thought of that. Seems so obvious now. Too bad everyone in my area thinks old saws are worth more than they were new. Something to look out for though.

Find a used treadmill. Variable speed DC motor, typically 1.5-2.5HP, speed controller, power supply, rollers already in bearing blocks, and a ton of other goodies. You can find them everywhere really cheap or free.

Cheers,
Brad

The type of steel rod you use isn’t going to matter much, it’s not like you are going to be putting so much load on it that you will break it. Id either go with cold rolled or some 4130 alloy steel, both of those should be pretty reasonable.

Get the woodsmith/shopnotes plans. They are designed to run off a table saw but you could use a dedicated motor.

Also +1 on treadmill motor. The older the treadmill the better. Some of the newer ones don’t have a discreet controller board.

yes, I have the ShopNotes issue with the plans. I’ve read it about a dozen times in the last week. Still looking for a treadmill, my problem is I don’t know a lot about speed controller, power supply, or anything else I’d find inside a typical treadmill, but if one comes up, I’ll be there, and see what I can do.

Have your say...
