Not worth the $
September 16, 2014
I used this to cut some 18" dia. circles in 10 ga. mild steel. I cut the circles two ways: 1) using the pivot base with extension, and 2) drilling a self-tapping screw and pivoting on a piece of aluminum wire, bent to fit around the plasma cutter head, and a little offset to float on the steel and keep the loop at the right height around the plasma cutter head. There was no difference in the quality of the circle for the cuts. I'm not sure it's worth almost $100 when a screw and a piece of aluminum wire works just as well..
