So I have wanted a thickness sander or drum sander, what ever you call it, for a while. Well I found a free treadmill on Craigslist. I salvaged a lot of the parts from the TM. I have the motor 95vdc, the belt rollers, the raising mechanism, the dampening mechanism, and the motor controller board.

Now as for the design I am stuck on here. First I have to see if the motor controller even works so I have to build a PWM to controll it. The real decision is do i use the DC motor and steel roller with bearings for the sanding drum, or do I use the DC motor and rollers for the conveyor feed? I can make a PWM controller for the motor to adjust the feed rate.

The rollers will allow me to use a 22” inch wide belt, which I cant find. I can get a belt fdrom Klingspor that is 25” and cut it down in width.

I am just asking for a little advice from some people that are smarter than me.

I will update the blog as I make progress.

Since you are having doubts and at a good stage, before you start, you might like to look at a totally different design. No feed belt (it can be successfully done manually) and no complex lifting mechanism (just one more thing that can go wrong). Its a design many here have built around (myself included, ) at least up to 18” wide. This design, whilst old, still stands the test of time .

Most of these things use a spiral wrap of abrasive strips about 4 inches wide.

Here is where I will buy belts for my treadmill sander. 2SAND Mine takes a 105X15 belt. Their prices are very reasonable. i.e. $30 for my belts. The treadmill I started with uses a Reeves Pulley for speed control. The same as my Shopsmith. Simple and effective.
I have mine ready to run but I’ve not figured out exactly how to make it into a thickness sander. I have several ideas. No good ones, though. Care to collaborate?
