thanks fellas! i would say this is one of the better $38 i've ever spent. the vise is a 4" pneumatic machinists vise, if anyone was on the prowl for one. the one i found had a damaged ratchet advance, so it sold cheaper. ive seen companies make them, but it just seemed like such a hassle as compared to this. if anyone has any questions, shoot me a pm. it is painfully simple...and i used c clamps for years, balls. brian
