Step 1: Tools and Materials
-metal lathe(optional, highly recommended)
-precision Dremel bits (small bits with coarse teeth)
-rat tail metal file
-400 grit sandpaper
-600 grit sandpaper
-Craftsman Bench Buffer(optional, makes things easier)
-3" to 6" round aluminum stock, 1" diameter
-one sheet of paper
-glue(stick, Elmer's, whatever)
Step 2: Design
Tips for designing:
-Be aware of your limitations. You'll probably want to stick to 2D designs for your first run.
-Lines should be far apart and easy to distinguish from one another. My simple JP symbol was more than challenging.
