Doing some type D.I.Y. fiberglass modular components for door jams
Just adjustable blanks that can used with low cost seals
I found that the price of pre- made doors are ok .But adding crating, shipping.
Can make two doors around $800 +.
So the first mistake is overly large .So now has become a porthole window.
Looking for five people to see what they can do. Want to build levered style
Will send two planks .No cost. All we will ask is that you post what you have done.
In the first picture & design has been changed. Porthole window builder Jerry.
Suggested to make deeper. So a simple ring can be used on the interior. See picture
