These are the molds custom Lego armorer Will Chapman of BrickArms uses to make his gats. BrickArms was recently mentioned in Chris Anderson’s genre-defining Atoms Are The New Bits article in WIRED, cited as an example of an amateur turning his or her hobby into a profession. I wrote Will to find out more about his molds:

  • 2.5″ x 2.5″ 6061 T6 aluminum
  • Cut using 1/16″ roughing ball nose cutter, and finished with 1/32″ ball nose cutter.
  • Cut using a Taig 2018 CR mill, with NEMA 23 steppers, driven by Gecko 201s via Mach 3 on XP.
  • Parts are injected with ABS resin – some of it is ground up Lego bricks.
