Just wanted to let people know that we have a pantographic optical tracing shape cutter on ebay. Make drawing with solid black line on white paper, move light/detector near the line, preheat, start cutting, move the light/detector to the line and it will follow the line and cut the part. Item # 7603040819. 3'x3' tracing and cutting tables, Victor oxy acetylene (or propylene or ...) torch with hoses. Can be converted to use a plasma torch, and
formatting link
has a cnc upgrade for $1800 that includes electronics, drive motors, and software.
I'll only post this this one time, so I hope no one is terribly offended :-).
