I saw this project discussed on the F1 Official Facebook group by Ian Dorosh and gave the design a try. I made three sizes of bowls. I made a small 4" bowl (without taping) on a F1. Then made a couple larger bowls taped to prevent scorch marks at 6" and 12" on the S1. Pretty easy to make and cut. It does take a little patience glueing them together. The results are pretty cool. Next time, I'll engrave a design on the base of the bowl.
