Top Left is the door cutout.
Top Right is the door trim ring.
In the middle is a cross section view from the top of the hinge area.. The black being the door trim, red is a spacer block for the hinge and orange being the door and sidewall. Silver is the hinge.
The bottom is a head on view of just the hinge area.
What I'm thinking is to make 2 of the trim rings for each door. One mounted on the inside of the cabin and one mounted on the outside of the door. That would give me 2 layers of weatherstripping and trim out the doors.
My doors and sidewalls are 3/4" and I'm using the 4 hole Torpedo Hinges from Austin Hardware. I have about 1/4" clearance between the doors and side walls. The inside ring shouldn't be any trouble but the outside one will need to be offset so that the overlap has clearance, at least that's what I'm thinking.
Now what I need is help figuring out how thick to make the trim rings and spacer plus how much overlap I can get away with on the outside ring to still have enough clearance to allow the door to open.
Any help on this would be great but I will fall back on trial and error if needed. My gazenta and cypherin skills are pretty rusty.

Thanks.
