Back Poor Mans Radius Guide
I've seen people do some beautiful freehand cuts with both Oxy and Plasma. Unfortunately I'm not one of them. I need some sort of guide for just about everything I cut. Straight lines are easy, just pick up any straight piece of metal and use it as a guide. On the other hand finding the correct sized guide for a radius is not all that easy.

I get a kick out of building an impromptu tool to make a job easier so after a little bit of thought and a rummage through the scrap bin I came up with an idea that would allow me to cut medium sized radii at next to no cost. I'm pleased to say the idea works brilliantly and once you get the first one done other sizes only take a few minutes to make.
