I'm glad someone out there is literate. Yes, it's "dowel" stock. The round stock that hardware stores and Home Centers sell. It's maple and won't bend and it's cheap. I use 1/2"

I thank Tor Henrik Furmyr for his nice drawing. I embed my wing nut upsidedown. I cut little holes in the dowel stock with a dremel tool and epoxy it in. I just use one small block of close cell foam as a bumper stop to keep the Dowel from turning.

My versions of this have been on strippers. I lay up 4 layers of 6 oz. cloth on the underside of the covers. The covers are like steel. I fill the weave on the edges to make a nice smooth seal against the gasket. They are curved which adds to the regidity. My back deck is flat. The glassing and striping construction keps it stiff also. If you're building with 3mm ply, you may have to brace it or laminate plywood under the covers to gain stiffness. You could experiment with glassing also. (both sides) Don't forget, the object is not to crank it down to a stress point, ...only to get a good seal. The mechanics of this could easily break a hatch cover.

I have had suction holding them on. Once I wiggled the knob, the pressure would be equalized and the cover would pop off. This is what led me to breather holes.

This is not a major engineering break through. If you experiment a bit you could come up with your own version that works great. My next experiment is with refrigerator magnet strips and refrigerator hollow gasket material.

good luck.
