I purchased an older floor stand model belt sander with a 6” wide belt. I brought it home plugged it in and I thought it was about to blast off when I turned it on. The belt and disk run WAY too fast. I can’t imagine the previous owner using it. It has a 3/4 hp motor that run 1720 RPM. Both pulleys are about the same size so that speed is directed right into the belt drive.

The motor has a single pulley. I don’t think I could go much smaller. The form factor of the sander prevent me from going bigger at the sander pulley.

I don’t want to spend $50 on a router speed control.

Any other ideas?

I don’t have a solution for you but I completely agree that belt sanders should not be running as fast as you describe. My belt sander is a ShopSmith (excellent sander) and since a ShopSmith is variable speed, I usually run it around 600 r.p.m. It feels right at that speed.

FYI – For me, a belt sander is not for fine sanding. It is for fast material removal with a relatively course belt. I usually have a 60 grit on it. I might run it a little faster if I had a finer grit on it.

I agree Rich. I use my statary belt sander for smaller pieces where I want to take the workpiece to the machine rather than the machine to the workpiece. I really don’t want my finger on a small piece next to this speed demon until I slow it down.

On occasion I use the far rounded tip of the belt sander to work an edge inside radius because my garage lacks a spindle sander. Just need to be sure to hold the piece square to the belt.

I will likely use the disc sander the most on this tool to work outside radii.
