@legs13,
Now that is what I envisioned! The execution is what I have questions with. Maybe some closeups will help in the discussion (if my phone will quit crappin out on me! I hate to admit my iPhone worked better than this android, but maybe its the cheap phone plan, lol).
I attempted that angle once. I tpok off the top layer of frame and tried to cut the hardware cloth to fit into the area neatly. I got the hardware cloth as good as I could in the area and put the screws through the preexisting holes and bent the hardware cloth to adequately go around the screws. What a nightmare it was and I spent hours wrestling with it. Even if in theory I got it to work, I would have to keep it together on the transfer to be upright and continue to screw the frame to the shell in the preexisting holes. At that point I realize the preexisting screws were too far apart (and not at the corners) making it a bad idea.
If I made my own screen, would it still work with the functional window? I guess I'm interpreting your suggestion as a replacement frame....
