I'm a blacksmith and knife maker. I was looking for another sander that wouldn't cost so much. When I saw this one, I took a chance. I'm so glad I did. This thing is my go to grinder in the shop. Everything came in two huge plywood boxes. Simple to set up, and almost no vibrations. It's got plenty of power to eat through carbon and stainless. My only regret is that I didn't get the variable speed control. It would have been way cheaper than buying a new motor(3 ph) and a VFD.
