I received my 500 from Discount Tommy a couple weeks ago- I expected crude-and this certainly is. The setting appeared rather wide, yet a few cranks and its grinding the plates. Metal flakes galore- more wobble than I think I can straighten out without a centered hole, straight line or square point to be found. I did break it all down ( that cotter pin was a biotch! ) I'm sure I can get it done somehow- too many folks here have, I'm just not sure where to start lol
