Plasma cutter circle cutter, quick and dirty

Quickly made from parts in my garage this circle cutter works a treat. I had 40 discs to make so it was worthwhile making up this tool. The blanks were later made into gears for a traction engine model. A video showing the gear cutting is shown here    • Simple Steam The Myfordboy Traction Engine...   The gear blanks in this video were cut out with a hacksaw, before I had the plasma cutter.
