The roof, again, plus rear frame . . . again

Design evolution, ie coming up with better ideas. The whole roof situation has been giving me a headache. I have been trying to incorperate a roof into the trailer design, which would be simple if it only had to protect from the rain, but it also has to give a significant amount of shade so the projected image can be seen.

After messing around with different designs, I have come to the conclusion that currently avaliable erectable marquees are a much better solution and come in cheaper than a custom made cover anyway. I can still incorperate attachments so it can be errected on concrete and doesnt need pegs, and guy ropes. Some images for an idea of how it would look with and without side walls:




The rear framework has had the initial glass layers put on, which has stiffened the whole rear area very well. More glass is needed on the side bar to add the load bearing strength. The aluminium foil in the pictures is what i have been using as a (almost) non sticking layer so i can put clamps and weights on top. A side benefit has turned out to be the way I can shape it and hold the setting glass in position. A lucky find though it is a little tricky to get off!
