Hey All,
Started the hatch, 4 ribs cut, 4 to go. Im going with 8 total, 1/2 ply, 3" tall on a 55 3/4" radious.
Started by mounting a pencil on a stick and drawing out the ribb, I then started to cut them out with a hand held jig saw.

Quickly realized that was going to take a long time with less than steller results.
I opted to mount my router to a stick and drill a couple holes at the oposit end at the desired length to creat the inner and outer radious.
I was able to get 5 ribs out of a 4x8 sheet.
The weights will keep them flat until assembly.
I need to add a little frame work to the wall to meet up with the inner radious "less the space for the gasket".
