Punching Holes in Sheetmetal

I want to punch squares or rectangles to get a stairstep southwest Indian design type of thing, or variations on that theme. Are there any punches made in a type that has a punch and a matching backup to help cut the design? I want to do these myself with a hammer, or perhaps there is something available that is run by air or hydraulic? Something that won't cost an arm and a leg, and punch different shapes of holes, squares, diamonds, rectangles, mostly about 1" max dimension in any direction, with the holes being smaller, and they could be drilled.

The cutouts would show up better without glaring in your eyes. One could apply contrasting finishes (or none) to the cutouts before tacking them in place. Fiddly, but I bet it'd look nice. Leave the bottom of the sconce open and paint the inside white. Pete Keillor |
