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.
<p>You never say whether these are front or rear bumpers. I'd love to see pics of the final version installed on your bug. Which way are they pointed? That's an important detail!</p>
<p>Hello! I work with Plasma cutting machines, and do many drawings plasma and has done very well, I did not like the quality of the Plasma in the AR-15 part, but congratulations is a beautiful design and a great idea. Here's a photo of a cut and assembly I made in High Definition Plasma 30Amps. If anyone wants this drawing in DXF extension, please send an e-mail to erico.rosso@baw.com.br asking for it.</p>
I'm guessing you don't get cut off in traffic!
Can we see pictures of the finished product?
As the new owner of a '75 bug (which I spent the summer remodeling), I'd love to see what these bumpers look like installed! Any plans for hand grenade turn signal covers?;-)
