It's very nice ... I just wanted to say in my opinion you can't go wrong with the flange wizard radius markers they are made in USA and good quality..... I was in a pinch once I had to cut a circle that was 12' 0" in so I just cut a piece of and tacked a center punch on one end and a soapstone holder on the other end had my helper hold the point in the the center punch hole and I carefully went around in a circle ... Cutting that ******* was the hard part it was 1" plate so I had to freehand it with a torch .... It worked but I had my helper using a rosebud ahead of me preheating
