After measuring out all the panels on the bottom half of the artoo dome, it was time to start cutting them out. You can do this with a small hacksaw, but fortunately I have a nice handheld multitool with some cutting blades.
Cutting metal with any type of powered device will generate a lot of heat. To avoid discoloration of the metal your cutting, be sure to keep it well lubricated with some WD40. The downside to this is it will create a big mess on your workbench, so be sure to cover it with some newspaper or cloth that you can toss out afterwards. Also, if you’re doing this, be sure to wear a facemask or respirator and some goggles. The metal dust is very fine and you don’t want that stuff in your airways and eyes.
