Brief Description: FABRICATE REAR DECK PLATE
|
|
I spent a day fabricating the rear deck plate area. This is where teh main electrical bus ties are located, the heater ducting enters the cockpit area, and the starter solenoid / Key West regulator are mounted.Photo 1: This is the top view of the rear deck plate prior to installation. I now have it cleco'd in place, final installation will be done once the wiring has been completed, and the heater ducting installed.Photo 2: This shows the rear deck plate in the vice being fabricated. This deck consists of two plates; the top plate [full size] is made of 0.020" 2024 T3 alclad aluminum, and is cut to fit full against the sides of the fuselage. Later on, this will form the bottom of a storage box area where extra oil, tools, spark plugs, and light materials can be stored for support of flight operations.Underneath the top plate, the bottom plate is made of aluminum honeycomb panel that is from Boeing aircraft surplus. This plate was originally made by Boeing as flooring material for their aircraft. It is very light, but incredibly strong. I chose to use it as a base plate for its strength in this rear area. Unfortunately I did not have enough in size to make a full size base plate, and so thus the need to fabricate the full size top plate. Photo 3: This is the bottom view showing the 4" opening for the heater ducting material. I will fabricate an accumulator canister to mount on the engine cooling shroud. The heat from off the cylinder heads will be channeled into this canister, into the ducting, and from there into the cockpit when a flapper valve is closed. When the flapper valve is open, this hot air will vent out side the aircraft as normal. I still have to fabricate the flapper valve, a choke cable will be mounted in the cockpit to activate it.
