what are you using Ink? I can come up with some piano hinge if you need it and poss a bit of aluminum 1/4in? or 1/8th in for a bottom plate, or some baltic birch for the base of the foam. You do have many options you just need to follow the path of the righteous let me know if you need anything Ink. We have tons of scrap here and many possibilities to work with.
Well I saved some foam for the main cushion in my seat.
I have the fabric. I have snaps to use to anchor the seat/fabric/cushion to the frame, so I can remove the fabric and wash it, (since it's whiteish, i imagine it will get dirty fast.) Id love to put a hinge on that "hump" at the rear of my frame, but I don't know how that'll work.
Do you have a blast cabinet up there? What I really need is to bob and blast my rear fender.....
