I was hating the way my old bumpers were looking on my 1968 vw bug so I made my own AR15 replacement bumpers! I was able to create the entire project using the machines and tools at techshop menlo park. I used the old bumper brackets, 3/16 mild steel, the cnc plasma cutter, corel draw, sandblaster, MIG welder and powder coating system to make these one of a kind bumpers.
Step 1: Plasma cutting the AR15s out
After creating my file and l uploaded it into the Torchmate software for the CNC plasma. I then entered all the different settings provided for the amperage and thickness of material into the machine. Once that was all settled I ran the gcode to ensure my parts would cut out in the correct order. I then enabled the torch to cut and ran the file. After everything was all cut out and my parts were cool enough to touch I started in on the removing of slag.
