I've just begun bladesmithing and I'm pretty much to a stopping point with my first blade until I get a grinder. Sure I could get a cheapo bench grinder or use hand tools but my dad has a good 1hp motor and a VFD and so we are designing and will soon build a belt grinder. I'm sure with my dad's experience in engineering and machining that we can design and build a great belt grinder, but I would like to get an opinion from anyone who is willing to share. What kind of design do you prefer? Has anyone else built their own grinder? What were some issues/learning moments that you had? Any recommendations for places to get parts and pieces from?
