Saw this listed on Marketplace as a grinder. Doesn't look like anything I've ever seen before. Some kind of motor-driven drum with an overhead attachment that runs on it? It's all cast, so I assume it's factory made.

Something like that showed up on our FBMP, but it was a 6x48 belt sander converted to a drum sander. That skinny wheel on top looks too narrow for that, but the intermediate roller might be. Maybe give you some thoughts.

But you need it, if just for the base and starter controls.

Looks to be a belt grinder. The small 'roller' resting on the big wheel looks to be a counter weight to me that will move in and out to adjust the tension on the belt. The top roller may pivot near 180* so the weight hangs out the back?

There's a bare spindle that makes me think there was a pulley of some sort and the arm is a tensioning weight. My gut says belt sander.

Factory belt grinders have enormously long belts. This certainly could be the driver with a tensioner to keep the belt from bouncing on the drive wheel.

Now I see the upper roller. The smaller roller/counterweight threw me. Still, without any kind of table or backstop it's fairly useless. The seller found it in a barn; I wonder if the other parts are laying around? No price given; best offer.
