ER Hatch hinges
I'm thinking about redoing my floor hatches. Changing my two 2 piece hatches on each side of my engine to a 1 piece hatch with hidden hinges and gas struts. Need a source for hidden hinges and maybe a tutorial on installation. Never done this before. My hatches are framed in 2X4s and the floor is 3/4 ply on 2X4 supports. Any advise would be greatly appreciated.
