. We make alot of stuff out of metal and a good circle was hard for me to do freehand. Using a tool like the one we show you here makes it easy to cut circles and washers out of any metal using a plasma cutter. It could also be used for some welding or grinding applications or as a crude PTO. For safety I designed this to be operated by 2 people .One person focuses on the feed speed (the turner),and the other focuses on the plasma gun location. This current design relies on having a hole in the center of the (to be ) circle. I usually have to have a hole there anyway but I plan to experiment with magnets to hold my rough blank in place.
