As I've previously posted, I've been working to build the structural wood to connect the skylight.
Here are all of the structural pieces finally fastened in place. The next step is to put the metal flashing back on the two open sides and then put the luan over everything. The rubber membrane and the Eternabond will follow.
One of the reasons that it has taken me so long is because I've been meticulous about keeping a constant slope to the roof. IMHO, one of the reasons for the original trouble, now that I've seen the damaged wood below, is that the installer of the original skylight didn't have the same constant level surface to screw into and attempted to use screws to bend the skylight material to meet the uneven surface, breaking parts along the RV wall and the covering that up with caulk.
This is a picture of the new skylight sitting in place over the structural wood before it was fastened. I wanted to make sure where the flange was going to be centered over the wood. I'm going to mark the skylight flange, separate it and drill the holes (the ones in the center of the vehicle will be hard to do over top of the dome if I don't) and the mark and drill the pilot holes for the new screws.
I'm hoping to have the project completed by the end of this coming weekend. I'll post more pictures when I have the flashing and luan in place. As you can see, I've already cut some of the luan to replace the damaged part on the ceiling.
The part of this whole project that has had me paranoid is the effect of the wind. We have driven into 40mph headwinds doing 60 mph. That gives us effectively a 100mph apparent wind over the top of the vehicle. I do realize that most of the pressure on the dome would be sheer load and that, because of the vent for the refrigerator almost directly in front of it, some of that wind pressure will be deflected away. Never the less, the last thing that I need is for the dome to fly off enroute because it wasn't tied down well enough. Yesterday, when I finished screwing the frame together, I grabbed it and was able to shake the whole RV on its springs. Since then, the glue has dried so it will be even stronger. I still have to add some self drilling screws to the sidewall structure to tie it into the wall. When that is done and I have the luan in place, I'll feel better about the whole thing.
Ideas and observations are still welcomed.
