Brief Description: Plumbed brake system and drilled top aft fuselage
|
|
Today Jim Anderson came over and we finished plumbing the brake system at the rudder pedals. Jim also helped meadjust and tighten the rudder cables. Next, we took off the entire tail and moved all of the parts (horizontal stabilizer, vertical stabilizer, elevators and rudder) to the upstairs playroom. Then, we tackled the top fuselage skin aft of the cockpit. After some grunting and using cinch cargo straps, we got the skin tight enough to place the 6 locating clecoes. Then, we wrestled the bulkheads into place under the prepunched holes in the skin. Before drilling, I did something new. I crawled into the fuselage with a light and a block of wood. With Jim on the outside and me on the inside, I lined up the bulkheads until Jim could see the red line we had drawn on the center of each bulkhead flange. This meant that the holes were dead center in the flange and could be drilled. Before drilling each hole, however, I would push up on the flange with the block of wood so that it would be tight and square to the skin before the hole was drilled. Then, Jim would drill the hole through the prepunched skin, into the flange and then into the block I was holding up against the flange. I am hoping that by lining everything up tight before drilling, it will make the riveting process smoother and lessen the need for shims to be riveted between the skin and the bulkheads later. After Jim left, I deburred and dimpled everything but the center holes on the skin (I will dimple them with the c-frame dimpler later.
