What technique would be recommended for cutting through thin gauges of sheet brass and copper (Preferably cheap)?
I am currently trying to find a solution to a year and a half long problem I've been working at, and was hoping the community could help me out. I ma trying to create miniature armatures that will always have the right proportions by etching the 'skeleton' out of thin brass (I believe it's somewhere around .02 inches thick). I've tried toner transfer and ferric chloride etching, but I am not getting steady results with the toner transfer. Since this isn't a circuit board, are there any other techniques I can use to cut through the metal quickly? If it's something along the lines of a CnC machine, as long as I can make it to cut down on the costs, I'm open to the idea. Just to give you an idea of what I'm trying now, at the moment I'm making stencils that I will spray acrylic or spray paint through onto the metal to allow for the same design every time. Acrylic and spray paint are also resistant to ferric chloride.
