I agree with Warren, the foredom is pretty small. I have and a friend of mine has used air hammers with modified hammer tips to move copper sheet. We were doing it on a 1 1/4" thick slab of metal as a backup and moved the metal against it. made for some great designs. I don't have any pictures of the work he did which was the majority of the work done. I have never tried it with backed up metal but I would think it would work great. Do be sure to get a good variable "speed" unit.
