I found a night school class in an adjoining county. It's an hour away, but it's in a nice vo-tech center and the instructors are guys who do it for a living. Also, I'm a "senior" so I don't have to pay tuition (lab fees are more than half of the cost, but I'll take where I can get it).

yeah I wish I could quit my day job. They have a great diesel lab but they don't offer it at night.

Got the hinges in.

I prototyped the hidden hinge arm, so the geometry works.

I am thinking about getting some arms waterjet from 3" steel billet, but I can probably make some from a couple layers of 3" 1/8 plate stacked after some precision bending.

This would have been easier with junkyard hinges but I wanted to retain the bluebird air ram and pivot for opening and closing.

I also got the stair floor pan in but forgot to take a pic.

Everything hinges on...

So I have these freakishly large hidden radius hinges I made from flat bar stock.

I wanted to get some waterjet cut from 3" steel bar, but it was sort of outside my budget. I did the next thing I could and hand forged 1/8" x 3" flat stock, and then forged a second layser formed and welded to the first. They are strong enough to hold a door for sure. I got one hinge fully complete but it got late and I'll weld the second layer on hinge #2 tomorrow.


Anyway, a video of operation in a mockup.

Very nice !
One thought, is your door opening going to be wide enough for big stuff, fridge stove etc?
One more coat of paint and my fridge would have to go out the windshield.

The finished door opening is 30" wide. Its actually about 1.5" wider than the bifold when open.

Also, I can just fully open, disconnect the auto opener linkage and remove the door for an extra bit of clearance.

I still have all the emergency exits too.

Door, now with 50% more door! Mordor? One does not simply walk to Mordor.

Frame outlines and such.



Closed, with plastic wrap to keep the damp out.


Hinge pivot inline with original bifold door actuator. Just reverse the air lines on the ram to make it go the right way.



Forward seal detail. I reused the bluebird forward seal. Just trimmed it a bit and turned it around. It now presses into a piece of 1" angle iron for the gasket. I think it will work great.

Some of the bracing. I'll add more as I go along.



Video of Darth Vader breathing and showing off his door.
