I have a 6×48 stationary belt sander that keeps breaking on me every time I use it. After a lot of work, the drive side was all fixed up and working great. But then of course the aluminum idler wheel/roller decided to disintegrate from the inside. Not wanting to sink a lot of money into the repair, I made a replacement out of hard maple on the lathe and inserted some new bearings in the end. Works like a charm:

It tracks better and is much quieter than the original, and seems to run fairly true.

Cool. I wish I hand done this to belt sander I let go 20 years ago.

Good solution. Do you use that 6×48 much?

Thanks. I only use it for metal for my blacksmithing side hobby. It burns wood too quickly to be useful on the woodworking side. I prefer using hand tools to get things to shape instead of abrasives. But for metal it’s awesome. I have a 24 grit zirconia belt that’s like boulders moving by on a freeway. Good way to clean up my crappy forgings.

I’m getting ready to do the same with my Delta 4X48. The idle rooler had bushings instead of bearings and they are worn out and the wheel is hollow. I will make one out of Walnut and install bearings like you did. Also building a 1X30 belt sander from scratch with wood rollers.

Nice, give it a go. I wish I could get a 2×72 belt grinder for knifemaking, but all the commercial ones are insanely expensive. But when I add up the materials and think of the time it would take me to build one, it still makes me consider buying one. I’m leaning towards one from wilmont, ameribrade, esteem, or a couple other makers.

Motor, bearings and belt are all you need to build one. All rollers and frame will be wood.

Thinking about it. A 2”X72” would be nice to build double sided. One side with a backer to keep the belt straight for grinding blades and such and the other side left loose for grinding handles and rounded objects.

I think an all wood frame would have too much flex, and metal gets expensive. A 2 HP motor runs about $250, a VFD for speed control would be another $150-$200. Steel for the frame would be a few hundred, the machined wheels and platen assembly would be a few hundred. You could machine your own wheels like this though.

John Heisz has plans you can buy for a 2×72 wood body belt grinder. Quite a number of people have built it and posted about over on his forums. Ibuildit.ca I’m hoping to build it myself this summer.
