And you have to have a press big enough to do this, and a surface grinder to sharpen your tools. I have a 10 and a 14 ton press in-house.
If you have never done it before my recommendation is don't. One good die crash and your out $700 or more.
Not to mention you need kick presses to punch holes, make multiple bends, then there's rotary tumblers, stone, cleaning, polishing.
It's seriously cost prohibitive.
