I recently made my first attempt at screen construction. I built a frame of 1x2s and stretched a sheet across it. I used L braces on the corners of the frame, but it has started to skew horizontally.

Is there any way to correct this, or will it be better to start over? If I do have to start fresh, what advice would anyone give for avoiding a recurrence of the same problem?

TIA,
Gerald Moore

Please pray for peace.

Cross braces, in the shape of an X. Then stretch as tight as you like.

But cotton expands with humidity. (wrinkles) Look for a fully-synthetic material. (nylon, rayon)

And best to have a dark wall behind it, or reflection (ghosting)

Cross braces from corner to corner? Or from mid-point on each side? The screen is in front of a window I blacked out with 4 mil black plastic. I think it is 50/50 cotton/poly.

I am concerned that the cross braces will show through the fabric. Would it make sense to paint it? I would have gone with blackout fabric, but the largest width I could find was 54", which is about 6" too narrow for 4:3 images.

Sorry, corner-to-corner.

Yes, the braces would show through, but line the screen back with black plastic. This'll slightly darken the picture, which is actually a benefit with DLP.

I'm using though, Formica in Ice White, 5'x10' trimmed to 16:9. (~$79 - Home Depot) Alot less trouble.

1x2 seems a little too light weight for me. I used 1x4 and don't need bracing, I just used steel L brackets and screws. The 1 x4 is just right for the black border that my lt150 projects at 80x60.

Failure is not an option. It comes bundled with every Microsoft product

Yes, 1x2 appears to be too light weight, as it has started to bow as well. Oh well, wasn't it Hemingway that said the first iteration of everything is s---?

It's passable for now, if a little annoying (to only me apparently, all I get is blank stares from the wife.) I've only spent about $15 or so, so far. Looks like iteration 2 is on the drawing boards.
