Bending oval stainless tubing into spiral: how???

Looks great

I'm thinking of heating the flatbar in the forge, twisting/bending it into the proper shape, I rolled this plate to the required radius, and then heating the half round and welding it on as I go, matching the core of the solid bar, it'll probably take a fusion weld, minimal filler rod, then just smooth it out with the sanding pad.

Another way that may be possible but a lot of work is cutting a bunch of pie shaped vee's out of the tubing and closing them up to make the curve.

is the chalk mark the pattern? Add support to the form. Also, add a way to reference level/twist, the cap will want to twist. Make a bending/twisting fork. I suspect the side of your fixture you end on will need to be trimmed or over bent to allow you to reach your target radius. Even trimming the excess above the line would be wise to assist clamping. Make sure you have plenty of clear space around you to compete the bend. A torch will work and will not need to remove the part once you start. Since, you have 3 then you will have some practice. Good luck
