Since I had to
open up the cockpit floor for the new engine, I might as well plan for
the future and make it easy to do again if needed.
I used a piece of 3/4 inch marine ply to make the hatch. By making a
pattern that was slightly larger than the cut-out would be when I opened
up the floor, it was a simple matter of cutting the ply, lay it on top
of the existing floor in the exact position I wanted. Then a place
a few number twelve machine screws right thru the plywood and into the
center of the floor.
Removed the ply, cut out the opening and then laid the ply right back
over the now removed section of floor, aligned the number twelve screws
and epoxy to glue the two pieces together
