Bioshock Belt Buckle in Bronze

Step 4 Machining!

Ok, so this is it, almost done.

Using the Tormach, or any CNC machine is a matter of trial, error and experience. The part I made was pretty simple so setting up the machine was fairly easy. I started with a piece of purple machinist's wax. I stuck it down to a wooden plank using some contact cement. This means I don't have to worry about the profile tool messing up the table if I accidentally cut through the wax. The machine needs a coordinate on the corner of my wax to set up the path, so I just maneuver the too there, call it the origin and load up the file I just made in DeskProto. The cutting took about an hour and afterward I had to brush all the little wax chips and dust out of the cracks in the finished wax. From here I made a box around the wax and poured in some RTV Silicone. This gave me a mold I could make some copies with. I used red wax (a medium-soft easy to cast wax that's super common and super cheap) to make some duplicates. After cleaning these up a bit it was off to the metal caster.
