To further explain...The bottom layer of ply (what ever thickness it was), combined with the rough cut (true 1" cedar boards) gave me the desired thickness. The ply really didn't provide much support. The support comes from the boards that fit into/under the horizontal C channel. and was attached like the original, just that now instead of screwing into whatever they used I was now going into solid 1" boards
and ply that were formed to fit the horizontal and vertical curvatures, sandwiched between the framing and skin. I added L brackets on the side of the vertical rails for good measure.
I also used a few metal roofing screws with rubber washers, screwing from below outside through the skin to attach the ply to the 12" boards. That secured the ply. The entire support comes from the boards, resting on the bulkhead at one end, running north to south and attached to the support aluminium frame along the side and in front. I used ( 4) 12" boards 1 on each side and 2 spaced in the middle. then 1' foam board to fill in the gaps between the boards then covered with ply cut to shape. The upper ply if I recall is not attached, its not going anywhere, i can then lift it to inspect for moisture.
At the time I did not have a design as such, it just kind of fell into place, I did't take any pictures really just a couple of the completed area.
The key is to get that curvature just right, so that the boards..whatever you use goes all the way in to meet the outside skin, which provides a thicker area of the board where you will have to screw into. You will have to form the side of the outer boards as well as the front corner and curve.
hope this help...I will be happy to PM anyone who wants to see pics.
No problem mon
