band saws

The idea of pushing a piece of sheet metal into a bandsaw blade, against a fence to make a laser straight cut at any blade angle just makes sense to me for what I'm trying to build. If you were trying to build a metal box out of 1/8 plate, what cutting tool would you use?
Well that much cutting, open box =5 pcs , I`d take the time to set up my plasma torch. I always use a straight guide and clamps for plasma cuts then face off with RA grinder if necessary. I thought you were just cutting one piece.
