The frames arrived before the lenses, so the first thing I made was the straps.
Heat screwdriver, stick it through the webbing to create a hole:
Two piece snap, and snap tools:
Use the snap tool and a hammer to flare the little tube on the inside of the snap:
Test fit of D ring:
Next step was to scratch build a plate to cover the massive hole in the front of the goggle frames:
Tapping threads into tabs for mounting the side knobs:
Big holes have small beginnings:
Unfortunately, the T-adapter comes completely anodized in black. Fortunately, the T-adapter can be disassembled, and anodizing can be removed. After a little research, I found that Easy-Off Oven Cleaner can be used to remove anodizing due to its lye content. Having disassembled the T-adapter, I sprayed oven cleaner on the smaller diameter portion. A few seconds later, the anodizing started to come off. I had to rinse the part and respray it a couple times, but with some light scrubbing with a brass brush, all the anodizing came off. Also, everyone keeps telling me that oven cleaner is really dangerous, so wear your PPEs!
I cut a disc of diffuser from an old LCD tv screen, and put it in the T-adapter (the T-adapter doesn't come with a lens). I also experimented with lighting the optics with some green LEDs, but decided to scrap that idea in favor of screen accuracy.
I painted the goggles olive drab, and began the final assembly:
The T2 rings are glued in place with clear E6000, and the optics screw into the T2 rings (M45 thread):
The extra holes are plugged with counter sunk socket head cap screws. Weather striping is added to the back of the frames. Knobs are installed.
Stickers are added, paint is lightly weathered, and voila! Ecto Goggles!
