That was 6 months ago and the 6" Vice has been sitting gathering dust until today. I took the 12 gauge steel skid that used to be under a 20KW generator and welded a 6 inch coupling into it. Cut a length of 6 inch pipe, bent some brackets from 3/16 strap and welded them on to hold the vice. I added 1/4x2 inch steel strap underneath to stiffen it up. It weighs twice what I can pick up, good thing the pipe unscrews. Figure I can stand on it and wrestle most anything. Still needs paint and a pin through the coupling to stop rotation but it's done. and someday I'll find a US vice that lives up to the stand.
