Hot wire cutter attachment
grabcad
The need to make "shadow boards" out of foam required some creativity. I developed a high current cascading step down transformer to get low voltage and high current through a nichrom wire. I configured some scrap material and cut a dovetail in a block to attach to the Bridgeport milling machine with a proto-track. traced a profile and foam was cut with nice smooth edges, suitable for use in a clean space environment.Don't know why the pic is upside down, I tried again with one rotated 180 and it still was up side down.
