Photo #1 -Is that concentration or constipation? Working on the front spar carry through strap. Photo #2 -Shows steel quarter inch bushings in the rear spar (front too). They are a little less than flush with each side. Also shows the spar wing strap before it is moved into place. Photo #3 -This is my main lower wing spar carry through from Hell. I worried this to death. Some said I didn't need much, some suggested I did. Called EAA for some advice and they put me in touch with a volunteer that said he could tell me for $600. Riiiight ...... The problem was I knew I needed some strength in this area and had to cut a big hole right in the middle for my controls. By capping my 1"x4" spar, top and bottom, with 1/8 - 6061 T-6 channel and then bolting them to the spar, I knew I could remove it if needed to work on the controls. The bottom channel is flush screwed through the quarter ply floor, then through 3/4" .080-4130 strap (later changed to 1/8"-4130) that spans the complete width of the fuselage. Very probably overkill but it isn't going to break, didn't cost $600 and is removable. Total weight about 3 lbs. but I didn't weigh it. Photo #4 -The angled plate attaches to the rear spar and the wing strap and attaches to the lower fuselage longeron. The spar is epoxied to the floor and this strap should keep it there. Photo #5 - The side of my foot could get trapped between the fuselage cross brace and the rudder pedal so I needed to add a side brush plate to prevent this. You can see the wooden cross brace at the top of the kick plate that was causing the problem. Rather large but I wear size 14 shoe. .......... (and no it isn't true what the girls think) Bottom Row
Photo #3 -Picked up my C-85 that was supposed to be modified with a different crank etc. to bring it up to around 100 H.P. Trouble is, no one (David Gouldsmith of Golden Aviation) told the engine guy Mike Redpath of Falcon Propellers. As a result it is just a C-85. It was supposed to be finished and ready to hang on the airplane which is why I drove 5 hours to just south of Okla. City, Ok to pick it up. As you can see it isn't finished. The box in the rear has the mag's less one mag gear, the generator less brushes, no spark plugs, no wire harness and the carb is laying to the right of the photo. Mike Redpath assured me he would get it up and running to my satisfaction. So I plugged all of the open holes after squirting oil inside and it will sit for a month or two until I get the engine mount made, then will return it to Mike Redpath to finish. The "F" word keeps coming to mind for some reason. (NOTE: By the end of Sept.-02 Mike had all of my parts except the spark plugs and now I have them) Photo #4 -After discussing my rudder cable problem with Dennis Robinson I decided to make a new rudder horn and put it on the bottom of the rudder. This change lessens the angular difference in the rudder cable vs the tailwheel cable. If I can figure a way to connect directly from the horn to the tailwheel I will do that. At this point it isn't feasible. Photo #5 -This shows the left aft sheeting after it was attached. The inside of the sheeting was coated with thinned epoxy. All contact points were coated with unthinned epoxy then nailed every two inches. There is a round hole at the bottom of the sheeting in the photo. I put it there so if at any time in the future. after covering, I needed to remove the main control horn for the elevators, I could. I decided to sheet in this manner for a couple of reasons. First by not sheeting until now, I could access areas that I needed access to and second because, at least in my mind, the stress on the entire fuselage structure would be less than if I had sheeted it before joining the sides as some builders do. |
