I am bonding the forward deck to the canopy frame. This one piece unit will then be cut so as to give a radius to the left/right front corners of the deck. The remaining deck will be strengthened from front to back to the original intended hinge attach point of the canopy. The original forward opening hinges will be used and their pivot points will be bolted to the aft side of the firewall near the top. The forward deck remaining, aft of the firewall at the top, is only about 2 1/2 inches long. This 2 1/2 inches is about all that has to be filled and part of that fill will consist of the rain gutter bids and the strengthening of the cut edge of the deck. The left/right radii for the forward deck will trail aft and down into the longeron. There are many more advantages to this approach than just the cowl/forward deck matching solution. The obvious and biggest advantage is ... with the canopy open to it's normal open position, everything forward of the control sticks and aft of the firewall, is visually available to check, repair, or to change out ... standing up alongside. You can top up the hyd fluid, electrical and work over master cylinders. You can work on all of the guts of the airplane forward of the sticks and behind the firewall. The smaller forward portion of the forward deck, is permanently bonded to the top of the firewall. The full length of the forward deck, resting on top of the longerons, is bonded to the longerons permanently. This will stiffen those joints more and make everything free of leaks from rain and ram air.
