You need to make up a simple jig. Clamp a nice heavy, straight chunk of bar stock over the sheet and hold the torch against it. For stuff that was really big you can rig up a old table saw with some clamps to hold the torch and then feed the sheet metal much like a sheet of plywood.
I used to get stuck making/repairing machine guards for custom machinery. Having access to power rolls, brakes and shears came in handy for other things too..
