Screen Tight and Stretched
Finally stopped watching the temp screen and have made some more progress on the screen. I added some 1x4's between the 2 center supports and some simpson metal ties across the center joint to strengthen the center section. Since I was adding some braces, I also added some corner braces to the already glued/screwed corners. Bonus, the new 1/4s also add some nice places to attach a french cleat.
Since I built a box instead of flat frame, I installed the screen tight on the outside edge towards the back of the frame and smoothed the edges/corners with some sandpaper so the spandex didn't snag. So that I had some working room to stretch the spandex, I elevated the frame a little. First layer of gray spandex stretched and clamped while my daughter and I installed the spline rolled in the first channel. Then the white spandex was stretched and clamped, and more spline in the second channel. Time to stretch the spandex and secure in the screen tight was about an hour.
I choose not to paint the frame yet, as this is temp round 2. I still need to frame football posts, and build the surround frames. Once that's done, I'm going to do 1 round of painting and re-stretch the spandex since it doesn't take much effort.
Here's a drawing of my concepts for the box frame, screen tight and surround frames. I think by building the surround frames out of 1x2's I will be able to fit them against the screen frame without affecting the spandex. Thoughts?
