Here you go vroom. Heres how I got my polar flat.

I layed the film in front of my collimator frame. I then taped one side all the way across. Make sure the film is firmly stretch and flat, and tape it on all sides with duct tape. If you tape it tighty, it won't curl up anymore.

If you don't have a fresnel frame like this, you can make an addition frame to hold the polarizer.

That's how I attached it to my LCD frame right when I got it. However, I didn't have duct tape so I had to settle with electrical tape, which eventually started peeling up.

I then made a frame out of cardboard and stapled the polar to that and slid it up to the LCD. This wasn't ideal because the cardboard isn't completely firm, so the polar can still bend.

I used to have my UV filter attached to my tempered glass frame using the duct tape method, but the filter ended up sagging anyway and getting wrinkles in it-- creating a rainbow effect on screen.

I'm really interested in optically adhering my films to the surfaces. The thread sank down, though, and I didn't see anyone who actually attempted it.

If optically adhering to the surface isn't an option, I'm interested in the "quick swap" polar idea. Creating a frame for the polar, then sliding it in place. The problem with this is I haven't come up with a thin, yet rigid material with which to make two frames that sandwich the polar.

Thinking cap will remain on, I guess.

P.S. Even though it would likely work, I'm trying to stay away from tape in my PJ. No matter how you look at it, it's basically a "temporary solution." Thanks for making this topic, though.

How about adheering it to the frame with ducttape this time?

(edit) yeah ducttape is not pretty and doesn't work forever. But it does last a very long time.

I too tried the electrical tape, but it let go with the heat. I realised it would only be temporary as I know the sticky and the tape eventually part company anyway. So I came up with these clamps: (LCD side of the collimating fresnel)

Nice, Ozstang!
