I found it helpful to build a box at the front of it to help with air flow. before I had what I called the Uhaul effect. air hitting the front and kinda slowing me down...

I plan on using a strip of 3/4" thick plywood under the 1/8" thick birch trailing edge, round the edge slightly, and epoxy-fiberglass it all together when done. I also expect to put vertical supports between each vent opening to brace the upper trailing edge and also under the hatch hinge support. Here's a draft detail (without vertical supports) I've been working on.KCStudly wrote:You may want to thicken up that trailing edge a tad though, just thinking if it is too thin it will sag or curl on you.
True, on edge is stronger but they intrudes more into the headroom. On the flat gives more glue surface. Since I've cut the notches flat, I'll have to dry fit it and check the sag.KCStudly wrote:Whenever possible it is better to run the roof spars "on edge". They will be stronger against bending/sagging that way.
I agree. See attached detail (Frank Bear hurricane hinge not shown; hinge will bridge gap between hatch 1x2 on left and two 1x2s on right.)KCStudly wrote:Also, depending on the hinge you select for the hatch, you may want to double up or use a 2x2 for the hatch side hinge spar.
I'll have to consider that. My current plan is to put 1x2 braces between the curved hatch spars so switching to a oak for all pieces would be a good idea. Nothing cut for that yet. I figure that will be made to fit once walls and dividers are up.KCStudly wrote:BTW, many people like to use hardwood for the hinge spars, oak or maple, because there will be a lot of leverage on the screws there and the hardwoods hold screws much better.
See the detail; rain will have a hard time getting to the hinge.KCStudly wrote:On the subject of hatch hinges, standard practice with a hurricane style hinge is to let the outer piece (IIRC) run long of each side to act as a rain diversion; gets the flow running off the roof or raised hatch out away from the wall where it can't hug the hinge and turn down into the galley. I'm wondering how that is going to work out for you with the hatch nested inside of the wall profile at the top.
That's true. Good news most of my camping will tend to drier areas. Otherwise I'll have to allow for a little water...KCStudly wrote:I can't imagine that there won't be a scenario where you might want or need to raise the hatch in the rain, and even if you wait for the rain to stop, any beaded water sitting on the hatch will want to run toward the hinge when the hatch is lifted. Something to consider.
