Little update. I've found the perfect spot to slide this filter in / out without touching the colour wheel (which is fragile + heat and vibrations will break up this filter easily).
The ideal spot for this DIY filter is between the exit of the collimating rod and the relay lens at the entrance of the optical cavity.
Yes, I had to literally take apart the entire projector to get to it. And I first had to cut a new mirror and test that (it works, phew) so I don't have the WCG filter installed right now, but I will soon. It'll be removable with a screw from the bottom of the case. The good news is is that my projector's image is perfect now, I cleaned everything including all the internal lenses and mirrors and DMD, and the lamp is actually good and bright! So scratch what I wrote before.
If I don't buy a new projector this year I believe I can mod this one into a new case and make it permanently quieter and possibly even do a contrast mod + replace the lens for a longer throw. Then I can use my anamorphic lens and wider zoom at the same time. (to actually benefit from higher lumens). Then I can also think about watching UHD Blurays via an Oppo 203 with anamorphic stretch at 4K and downscale it to 1080p from an HD Fury Linker, or just watch it from my PC. Of course what I really want is quiet + WCG + contrast mod + higher brightness (different lamp, at least 3000-4000 lumens possible) + quasi HDR. This is quite a little piece of kit and I know it like the back of my hand.
I can take it all apart and put it back together, from memory, really quick and fully functional. I also now like one of the other designs I saw before, with a grayscale 1080p LCD with high transmissivity: basically put that on the outside of this projector. So use just an LCD panel + HDMI board as a "relay projector". The w1070 wouldn't even need to be opened or modified at all. Instead of putting an anamorphic lens in front of the w1070, you could put another light modulator to achieve 1M:1 contrast ratio.
And then get the best of both worlds: DLP motion handling combined with mega contrast, WCG...and eventually HDR10 with some custom shaders via PC playback at least. And of course that's without even going into the idea of using RGB lasers or LEDs to retrofit the light source. Rec 2020 lasers are definitely do-able although I'm not sure how expensive it'd be to get lots of lumens out of it. I think the price of green lasers should come down soon so DIY light source upgrades should be possible.
