I still haven't made it past the store at the corner but at least started mocking a riser frame of popsicle sticks to create a loft with this eventually.
Make & mount them on the door 1st. The posts are easier to judge alignment to the hole than visa versa imo.
ATTENTION, this really should have pivoted the latch on the right door as the left door holds the vertical gap backing so the right opens first. Ideally, you only want to open one door at times (storms, etc). This way the left will drag the right one open slightly until the left's lip clears.
A hinge pin hole burt through with a ¼" 6.3mm heavy duty staple for a small staple gun. Glue will go on the back side of the hole pointing down from the hole. A fresh staple in place vs heated one. (I also added a "foundation" I wanted to look like concrete but I'm thinking dark railroad tie brown and added holes to have come from a turnout; I think I can get some graining going.)
I could have nit picked more obviously. At least put my glasses on more often 
Best shot of pin/knob ...maybe bar fit.
Glue may not be needed in places. (backside)
Just below the latch pivot is a small thru hole I burnt with a pin too low. The angle of the diagnal brace wood allowed a good distance with only a slight increase in height so the wood didn't suffer any char weakness from holes being close.
I could have nipped brass or aluminum and pulled of better; with hole punching & pins used for carriage bolt heads, and styrene square nuts. (start nut large, make hole/ mount nut to pin tip, clip pin, trim nut small, paint).
You could try grinding pin head smaller to scale turned in a dremel and rubbed on abrasives, files, etc.
The "catch" (I think that might be right ..?) is just like a hinge post but trimmed to clear the latch board ....with nippers. The guide is a normal staple.
Best pivot focus/contrast
Im'a gonna yous da ropes like dis🤤 I'll bee in-tide dune updated a nott soon I no it 
🤣 
( rope goes on the left door 🤣 maybe into the gap; There is a vertical lip on the left door, right door sort of opens first 
)
