What a great set of simple instructions. After watching dozens of videos with exhaustive instructions it is a breath of fresh air to see this laid out this way. I am doing this ellipse on a 4×8 ft steel sheet and welding the rods to it. I am using wire instead of string and then taking my plasma cutter to it. I am excited to see the results. Thank you again.

So clear and so practical. Like David, I just watched 30 minutes worth of videos and this is the most straightforward explanation I have seen. My fire pit cover will be more refined thanks to you!

This works great, but it’s not clear how to establish point C here. The center peak (point C) should be 1/6 of the overall width. So for a 60″ wide cased opening, the center would be 10″ above the major axis or spring line. For a 48″ wide opening, the center would be 8″ above the spring line and so on. In other words a 6:1 ratio for the rise relative to the overall length.
