Bb. Here you go.
I took advantage of the boxed in roof design and removed both inner and outer skins which left a boxed framework to work from.
.
.
Next I bent 8" x 1/8" steel plates to match the contour of the bus.
.
Then welded up the plates and the square tube frame.
.
Test fit the top.
.
Installed the pair of linear actuators that open and close the top.
.
Then I affixed the polycarbonate sheets to the frame using 3M industrial double stick tape as directed by the mfg of the polycarbonate. I added the stainless steel piano hinge and bolted the hinge to the roof.
.
Visable here are the three 1/2" carriage boltd that pass thropugh the roof to secure the top while it is in the closed position. You can also see the Sunbrella brand tenting that keeps stray objects from entering the bus when the top is up. The weather striping is press on butyl rubber which (so far) has created a wind and rain proof seal.
.
The last image is of my wife cooking dinner. Just above the water jugs you can see one of the stainless steel cups that the carriage bolts enter when the top is down. Once the top is down I simply twist on the wing nuts and the open side of the top becomes secure.
.
Just kidding now---if you would go to bed earlier, you'd be ready to get up at 5:30 AM. Failing that, perhaps a sleeping mask would allow you to sleep in late. Just saying.
