No more questions threads...spent the past hour or so with several tabs open on my laptop doing the math for this...

Been using the calculator that can be found here....

I have not cut my tank open so I am assuming, at least for right now that it is constructed from 1/8" steel. This may be a mistake but it is what it is...I measured the circumference of it and came up with 63.5", according to several on line calculators I have used

http://www.csgnetwork.com/picalc2.html

this puts the diameter at 20.21", which I will just call 20.25". This info will be needed when I get to the "circle calculator" stage of this nightmare.

Anyhow, I came up with a cooking chamber (cc) volume of 13860 cubic inches.

Using this number to figure out the size of the cutout between the firebox (fb) and cc I came up with 55.44 cubic inches....this will need to be known when I get to the "circle calculator"....

The area under the RF plate is also 55.44 cubic inches. This translates to the RF plate being tied into the top of the port between the fb/cc.

The area needed at the far end of the RF plate is also 55.44 cubic inches. Not real sure how this will be figured out. I have read that the RF plate needs to have a slight drop to it compared to the fb end. How much of a drop is necessary? How far from the dome to I end the RF plate? Math and I are far from best friends so....

If any of the above is incorrect please do point out my errors...

This seems like a logical point for me to end this post.....
