#1 - My first machine was a 3-axis engraver.

#2 - was a 3-axis gantry for a plasma cutter. I co-designed the machine with a co-op student I had in my shop at the time, and I built the controls and electronics.  The finished machine was placed in the High School.

#3 - was a partial build. The High School had a 1988 Light Machines lathe that the controller was toasted, and had been mishandled. I overhauled the machine, built new controls from scratch and added a spindle indexer so they could use it for threading.
