Well I learned how to do all this in a metals class my college offered this semester. You use a small saw blade to cut the metal. If you go onto riogrande.com you'll find a lot of good tools and material to use
you should go check the colleges around you and see if any of them offer a metalsmithing class! It was alot of fun when I took it, and wasn't extremely difficult However, i will warn you that soldering is a Pain in the ASS!!!!
