Ok, finally got ALL the major skin attached. It's not all riveted into place, but as I can wheedle my friends into holding a bucking bar competently I'll get the rest of the rivets in.
I still need to fill in the holes where the old flashing lights went.
I'm using a cold galvanizing zinc spray between the ribs and the sheet panels, hopefully that will keep down oxidization. I may end up just spraying the zinc coating all on the inside anyway, since it will eventually be trapped between insulation.
Once all the panels are enclosed, and I've got a relatively leak-free envelope, I'll start ripping up the flooring. I feel like I've been doing this backwards because everyone seems to tear the floors out first!
In the 3rd photo you can see the end flange I haven't trimmed it down properly yet so it sort of hangs off like a big ugly square...thing.
In the 4th photo I still haven't ground down some of the weld seams to flush, I just lightly dressed with the flap disc and covered with primer so things don't rust here in the pacific north-wet.
In the last photo, you can see how the panels lay with just a couple clecos holding things together. Once they're riveted it'll look a lot more like a "proper" bus shaped object. I'm pretty happy with the
stance the bus has given the size of the wheels, and the height of the chassis.
Once everything's riveted in, I'll get that upgraded rain gutter/drip rail installed as well, and maybe get some better paint on the outside. It's just primer for now to keep things from turning brown (rusty).
