Here is a used plasma cutter I scooped on ebay after getting some advice from some inmates. It makes fabrication much easier.
I made the cart from all the free scrap metal I mentioned earlier. The wheels are from a broken dolly that I had packratted away. I knew being a hoarder would eventually pan out.
The top of the cart is from a scrap side panel from a piece of industrial switchgear from an upgrade. I cut it with the plasma cutter.
I have since rattlecanned it satin black with Rustoleum.
