Btw I used autodesk inventor to lay it out. It took less than 2 minutes. It's an excellent program if it's in the finances. I hoe it works out for you.

Attached is formula for figuring a cone segment for "rolling".

Forgive me for the font and scale and ugly dwg but you get the picture, I just drew this up quick.

Decide how many segments you want to fabricate the cone out of, depending on
capabilities of your shop and roll and table then input into formula.

I used Centerline dimensions on the sketch, especially for plate 1/2" thick. Opinions will be
everywhere on that but regardless, the formula will get you what you need.
