With that pleasantry out of the way, we started on the framing for the forward bulkhead and the roof.
The design for the bulkhead on Sketchup looks like this:
.
The bulkhead in real life:
Pretty darned good I think!
.
With the bulkhead out of the way we move along to the roof. This gets a little tricky. Beth cut out the curved pieces, and we clamped the outer framerails to the walls. We cut a bunch of 1.5" spars to span across the walls, pocket-holed them with the Kreg Jig and carefully pieced together the roof frame. The design allows us to remove the whole roof frame (and the bulkhead) from the trailer. (more on that later)
.
We took the words "Sparring Partners" to a whole 'nother level!
Yeah, it seems like a lot of spars, but this is going to be a solidly built trailer. The teardrop people constantly talk of everyone overbuilding the trailers. We are doing just that!
.
The spars for the hatch hinge are two pieces of oak laminated together, and firmly placed with its own supporting spars. You can easily see the Kreg Jig pocket holes.
.
With the framework done, we took down the bulkhead and the roof, and glued and stapled the interior panelling to them.
The bulkhead gets a layer of 1/4" luan. It's going to be hidden behind a headboard, so it didn't have to be a more expensive piece of Birch. The gap is where the bed floor fits in between the bedroom and the basement storage.
.
The roof was done in two layers of 1/8" Birch ply. Two layers were used just to make it easier to follow the curvature of the roofline. Yes, we know you can bend 1/4", but it is a bit trickier and a bit more work. It took a lot of Liguid Nails, clamps and staples.
.
Here's our way to skin this cat
.
Here's the finished product, two layers of Birch, flush trimmed to follow the framework, and the hole in the middle is the opening for the MaxxAir Fan we have waiting for installation.
.
What you don't see: After the first layer was installed and trimmed, we started on the second layer. The Birch ply would overhang the edges of the frame by a few inches. I couldn't see where to place the staples accurately. Easy enough for the spars, we used a laser level sighting along the center of each spar and stapled away. We were initially doing the same thing for the edges, but in a fit of distraction, I was using my thumb as a "feel good" guide. Well, in some places, when you get close to the edge with a staple, it might just come though at an angle and poke out the side of the framerail.
The words are still plain in my head
"Be careful, you'll staple your thumb that way"
Yep, sure will
.
That minor injury taken care of, we called the kids for help and placed the bulkhead and roof back on the trailer. This is to keep the "set" in the roofline while the glue dries. The flat panels want to pull the curve out of the roofline, so this makes sure it will keep its curve memory.

The interior, in case you are wondering: the ceiling panels are not polyurethaned yet. They'll look more consistent after a coat or three....

and here's the full shot showing you how the thing sits today. Beauty, eh!
