I was way too cheap to buy a harbor freight buffer, so I built my own .It works great and has a lot of power and is rock solid. The only problem is that I should have made it smaller instead of a whole work bench thing,it takes up a lot of space in a small shop.The wire wheels are the best thing for cleaning rusted parts The antique grinder is nice because it runs slower than a regular bench grinder so it doesn't heat the crap out of parts. I mostly use it rough shaping like rounding corners and edges. I also made a sheet metal bending brake from 2x2 angle iron,simple and slow but it works.
