Pantograph Plasma Shape Cutting Machine

[Bill KunzParticipant @billkunz39862]

I fabricated this pantograph shape plasma cutting machine for duplicating steel brackets and other hardware. A variable speed magnetic knurled rotor moves around an overhead mounted template. The plasma torch tip, directly below, duplicates the shape in steel up to the thickness capacity of your plasma cutter. Shapes that would fit in a 16 inch circle, and straight lines up to 36" can be cut.

The frame of the machine is constructed of aluminum extrusions from the 8020 Company. The rest was fabricated from square tubing and cold roll steel bar. A model railroad transformer and small gear motor provide variable speeds in forward and reverse. Magnetic tracing rotor consists of a rare search magnet sitting atop a rotary burr.

Small holes can be drilled after parts are cut out.

Looks like a very capable setup

Are you going to do a construction article?

That is really ingenious. And equally well executed. Nice job!
