Cut square hole in sheet metal?

Cut square hole in sheet metal?
Hey everyone. I need to make a patch for my truck bed. It needs to have a sq. hole for one of carriage bolts that hold bed to frame. I thought about welding together two pieces with L cuts to make a square, but it seems like a lot of work. Is there an easier way?

Typicaly, I just drill a slightly larger round hole, and use a carriage bolt and nut, and maybe washers. Nut pulls the carriage bolt in place. I use a drill gage to check for a hole that will still bite in the round hole. Example, 5/16" hole works for a 1/4" carriage bolt. If it's thin sheet metal, a washer helps so the nut will draw up tight. If it's thicker steel, a small file will easily make the 4 corners.

I have used a triangular file to square a round hole many times. It doesn't take that long but this is a good alternative if you have the right sized chisels and a great anvil. What I have wished for but haven't yet found is a fixture for my pneumatic chisel that holds a file allowing me to exert pressure on both ends as it reciprocates back and forth at higher than my arm speed. It would need to reinforce the backside of the file lest I break all my files in half. Why hasn't this been invented yet or have I missed it?
