hinge pictures?

I think I understand the principle of what you are saying, Does hinge attach to the hatch from underneath via the studs?

Yes!

I used a flat piano hinge and covered over the top with flat rubber material wider than the hinge and pinned down the sides with flat bar aluminum that is screwed down to hold them in place

That would work too. The main difference is you see your screws, my way they would be hidden!

Okay, But how do attach the hinge to the hatch attach points and still make it strong enough to support the movement and the weight of the hatch. I was always under the impression that the real strength of a piano hinge was the mutiple attach points (lot of tiny screws) and that sounds like alot of studs to me. Way to much work, Remember "KISS" method of design and building. Not to take anything away from your design, it is interesting.

You'd have to put a little nut underneath each stud where it comes thru the hatch, or the roof.

Assuming you put a stud every 6" or so, on a 48" wide trailer you'd have about 18 little studs.

Yes, it's way too much work for me, but you asked!!!

I knew it was my fault for asking, I couldn't help it

I'm completely out of my mind..I'll be using pivot points for my galley, with a piece of rubber across the gap to seal it..i'll have pics soon.
