I'm not a sharpening guru. I do remember reading about some old grinders that were highly praised,,,maybe even for square grinding? Is this at least part of that setup?
nor I but I gotta ask The green part looks like it could possibly hold a lawnmower blade but but but It’s listed as a saw grinder but but but
If the sticker on the motor is a good clue, it looks like it’s for sharpening the teeth on old buzzsaw style blades.
Yeah, that’s it. The contraption on the right locates the center hole of the circular blade. The post on the left is a stop for the backside of each tooth.
That makes sense. Never thought of a buzz saw. I’ve got one but don’t use it anymore. Would have been fun tho
