Hi Thomb
I'm not to sure why you are playing with the numbers,,, it takes two templates to make a cathedral door... and all the math is done for you with the premade templates..
They come in many sizes, to make a 4" wide door to a 24" wide door...
Many woodworkers supply companys sell them here's just two of them..
