When we moved to Texas, we had more space to take advantage of. I decided to build a permanent screen.

We’ve gone through three iterations of our screen in Texas.
V1 is made with electrical tubing, from which I hung blackout cloth as a screen. This was difficult to put up and store, but it was our biggest screen.
V2 is solid construction. I used 3/8″ ply for the screen, because I was concerned about weight. It started warping almost immediately.
V3 is 1/2″ ply, and is the biggest I’ve ever made. It’s heavy (the whole family on pulleys was needed to put it up). It’s heavy enough that in some of our more aggressive weather, one of the legs failed. I spliced a support onto it rather than replace the leg outright, and it’s a much more stable structure.
You can also see here the sound system. I installed new speakers into old cleaned up drive-in cases, and wired that up. They’re tied in using large audio jacks, so I can pull them in off season.
