I did this job for a Thermal Dynamics sl60 burner. It's not perfect, but it's sufficient. I can't believe I've been using washers and can lids for so long. If you're cutting steel and don't want to drill a hole in the center, get some small donut-shaped magnets to hold the center of the circle. I've also used a donut clip on non-magnetic metals.
