I laid out the main crutch, added the cross members and cross bracing. I built the window tracks and installed the formers. I used the actual window to make sure they would slide up and down smoothly by keeping the correct distance. I made sure all of the formers were 90 degrees to the table and added the stringers. I sheeted he turtle deck with the special .025 plywood. I have not sheeted the forward section yet, because I’m planning a few things on and behind the instrument panel. I will make a special brace to hold that section square and straight when I start to add the bottom formers.
