There is work to be done

As you can see some work has already been done

No it is not an "IF" hood, the LEXON has a coating of thin plastic to protect it from scratches. The frame of the canopy is made of commercial 10mm x 10mm aluminum square tubing. the front is a single sheet of LEXON bent around the canopy frame and over the fuel tank with 1mm aluminum roof flashing bonded onto the tank and pop riveted to the Lexon. The same aluminum flashing is rolled and bent over the frame and riveted to both the frame and the Lexon. Double sided tape is used to secure the Lexon to the flashing before riveting. The center section is Square tubing bent to the same size as the front canopy frame with runner at the bottom that interlocks with the runner at the cockpit gunwale. To the rear of the gunwales the runners are extended to run parallel on two wedge shaped ply boxes.

The rear section of the canopy is formed the same way as the front windscreen but the flashing is pop riveted to the ply turtle deck. The joint between the frame and the Lexon is done the same as the front windscreen to frame method. The frame of the aft section is formed to fit inside the center section frames to allow the center section to slide over the aft section. Two stopping screws are located at the aft end of the lower runners to stop the sliding section from sliding off.

The most important part of the job is to build up the cockpit gunwale to a level above the wing support struts and not forgetting to leave holes in it for the struts to go through. With this modification, as there is no ventilation installed, the occupant will be cooked, even on a mild day. As it is a real hot-house in there even inside the garage on a cool day. I will have to make a system to force fresh air into the cockpit for the normal to hot days and a hot air system for the colder winter days.
