I built one a few years ago.  I used 1X1 (by 3/16 thick, I think)
angle for the bottom, welded to a 1/4" bar stock.  The top was a 1X1
square rod.  That was welded to a 1/4" bar stock, too.  the dies were
mounted to steel 2X4 (by 1/8 or 3/16 thick.).  The frame was 1X1X1/8
square tube, with a shim between them and the bottom 2X4.  This worked
well enough for the one-off we built it for.  I couldn't get quite 90
degree angles out of it, without suplemental use of a hamme, but htey
were close.
