Re: Question about collimated display systems.
Dinther - give me a day or so, I'll upload the mirror-screen geometry to 3D warehouse. You can try the actual design geometry with Shaderlight to see that it works. Note that the screen is not located at R/2. The screen shape is very important in properly placing the image - as little as .25" out of place will put the image either too close to appear collimated, or beyond infinity, causing diverging focus, which is very hard on the eyes.
EDIT:
Model containing only the mirror, screen and default cardboard-cutout girl has been uploaded to 3D Warehouse.

Re: Question about collimated display systems.
The design review is done and after a few adjustments are done, poor castle will be up to his neck in trouble.
The assembly manual will be written once I've got a chance to tweak the single-seat design that Wayne & I built.
I want to incorporate the changes from the 737 part design into the smaller one. This will "normalize" the components across all three designs so one manual will work for all three.
Castle is correct - CNC cut parts are pretty much a requirement. You'll also need a full size (not a table-top) band saw in order to post process some of the parts.

Re: Question about collimated display systems.
Probably not, those have a larger radius mirror of 9 feet plus where as Gene and Wayne's design is 8 feet whch is just about the minimum radius for the 737. For a full 180 degree mirror the diameter at the end points is 16 feet plus about another foot for the top of the frame. The projection screen has a radius just over 5 feet and you need to have a ceiling height over 10 feet. It's a large structure.

Re: Question about collimated display systems.
Have you guys thought of integrating Paul Bourke work (iDome) iDome images with mylar material?
BenQ has just launched an affordable 1080p short-throw projector (~1000 USD, W1080ST model) and it may be possible to do wrap around visuals with one projector. This is the route I'm looking into, to obviously try and save cost.

Dome projection systems do not create a virtual image as do collimated mirror systems. And there are significant differences in how the image(s) are created and the effective FOVs.

Re: Question about collimated display systems.
how much does the colimated display take? for a 737 without the shell, just the interior

Question about collimated display systems
That might help, but I confess to being a little confused about what the real difference in an "article", "blog" and quality "forum" post is...For the photo threads perhaps consider some sort of form with pistol information? Way to make a picture a required element?

This would only be good for a single pilot. With 2 a side-by-side pilots. See the image of the glass mountain (Flight Safety International) Concave mirror and beamsplitter.
The 20" flat screen monitor is on top facing down. So, the footprint of the optics is vertical. The doors slide for complete isolation.
The cockpit controls could be replaced. But, this is about the smallest footprint 3.5' wide, 7'long, 6.75' high to get a VR.
At least it can provide the mental model.
An updated 1080 or 4K monitor should do well if the refresh rate is high to preserve true color.
