CNC plasma using a workbench as a table

[Tmate]

This was one of my first efforts in building a CNC machine. At the time, it used an oxy-acetylene torch, but it would just as easily accept a manual plasma torch with a switch placed into the trigger circuit.

It used cam followers riding on the edge of a steel workbench as a table, and had a gear rack screwed to the table surface. This was a cantilevered unit and the material was situated off to the side. The photo was taken just after I finished it.
