Has anyone ever used one of these ? I got this one at a estate sale for $5 it takes a 1.5 x 24 inch belt 1/4 hp. they seem to be used for sharpening has a guide to adjust angle, runs really good. I have found several sources for the belts and they are cheap even for Norton belts. they still make them and a new one is around $500 . just wondered if anyone has one or had used one.
