i mean completely weatherproof at the joins where it would be mounted to the roof.. like alot of domes "seep" from the bottom,, if there light metal tubing cause most of them are just sitting on the ground.
to avoid this alot of domebuilders just go to wood for everything and put them on a foundation... but wood is too heavy for my style.
maybe have a wood "frame" around the perimeter of the bottom of the oval and use metal tubing from there. and i was gonna start this thread into maybe fiberglassing it after its wrapped in canvas.....
butttttttt i can guarantee that im over thinking but i aint new to that. im also not new to doing things and thinking to little about them and have HUGE pet peave

about the whole project, i just want to be happy with a design first.
