Purchased this Delta 1" Belt / 8" Disc Sander in 1995. Bolted it to wooden top, on top of the Delta Model 50-330 Universal Stand. I have found this in Delta Catalogs from 1991 to 2000. Since 2000 I have seen this exact frame and model of a sander sold under other manufactures names. Not sure of the full history. I could not find an info plate on the sander, only the plate for the motor.

This is a wonderful machine. I use it probably more often than any other machine in my shop. With 40 or 60 grit belt, it does a great job of sharpening lawn mower blades or axes. I use it to file down bolt heads, nail heads, small wood objects, etc. It's uses are endless.
