Okay, to provide some context:
Going to be milling copper, would like around a 4" opening. Primarily working with a piece around 2.5" wide, to about 4" long.
Gonna be milling around the outside of the copper, as well as working within the piece.
Could anyone please suggest a somewhat feasible vise?
Thanks guys, appreciate it a lot

(Saw that in the smileys list, decided why not?!?)
