What kind of scroll (saber) saw?
I have a Makita saber saw with variable speed and four orbital settings (from straight up and down to a progressively greater oval pattern which helps shed debris from the teeth) and it works very good on sheet metal. For very thin stuff, sandwiching between plywood or luan helps stabilize the metal.
I bought this type of saw based on Ron Fournier"s first book, because it was the most versatile way to cut so many things. It's pretty slow to use for cutting 1/4 plate steel but works great with lots cleaner edge than using a torch. Until I get a Beverly, this and my Kett electric shear (added since the Makita saw) are what I use.
