Im having issues finding a 2 x 72 belt grinder anywhere but online and they seem quite expensive. I found this at a tool store in my area and thought it might work well. It is 3 x 78 belt size with a 2 hp motor. The store had belts from 30 grit to 120 grit and this is the first ive seen that size so i dont know whats available. The person i talked to working there is a bladesmith himself and he thought it would work well but i have heard that having to wide of a belt can be bad. The sander costs about 850. Would it work good?
