Sure, KennyG: it's all just material I had lying around.
Roof of 1/2" plywood, doubled up in the stressed areas or where there would be multiple screws for lights, etc.
Border of 1" x 1 1/2" ceder.
3" U-bolts, 2x4"s under and above distribute the stresses.
Everything glued and screwed w/ polyurethane glue (Gorilla glue).
Painted with 2 coats of rubberized RV roof coating/primer.
Top coat of dark grey Rustoleum spray paint.
Without the front supports, it would have worked fine, but it vibrated a bit.
I had some 1/2" threaded rod which fits perfectly inside EMT conduit, and I don't have an EMT bender so the 1/2" is easier to bend.
The holes in the loader frame were pre-drilled. I just bent some long bolts into 90 deg angles. The bolt heads fit quite snugly into the EMT with minimal grinding of the heads with an angle grinder. I was planning on securing them with J-B weld but didn't have to.
Been a 'Niner fan all my life, but this game is hard to watch.
That's a nice canopy, but what happens when you want to remove the loader??? Seems kind of problematic since the front of the canopy will have no support, if the loader was removed.
I bought a golf cart canopy last fall and plan to adapt it on my JD 790 before summertime gets here. Still working out the design the frame for it.
