|One thing that I neglected to do was to match the curve of the front of the E-714 counterweight to match the curve of the E-713 counterbalance skin. It says to do this in area G-2 of drawing 5. I decided that the way to do this was to remove the elevator from the HS first.|
|I want to match the curve of E-713 but I want to have enough room for a layer of fiberglass. So I need to remove a fair amount of lead. Of course, this is going to throw off the balance, but I have a plan for that.|
|Since I want to fabricate a fiberglass end piece, and since it's not going to be flat. I calculated what the curve should be based on the fact that the radius from the pivot point to the end of the counterbalance arm is 9.5 inches. I then bend a piece of aluminum to match this curve. This is where I'll place the fiberglass panel to cure.|
|OK, Here goes. Never did this before...
I started by painting a layer of epoxy about 4 inches square on a piece of wax paper. I placed a piece of glass cloth over that and painted it on, making sure I've completely covered the cloth with epoxy. I did this for 3 layers of cloth painting more epoxy on the top of each layer of cloth.
|Then I folder the wax paper over and rolled it.|
|Finally, I set the whole thing down on my preformed aluminum so that it takes the shape of my curve.|
|Nothing to do now but wait 10 hours. That's how long it takes to completely cure. In the meantime, I fabricated another aluminum strip and Gorilla Glued it to the E-612 fiberglass tip. Only have to wait 3 hours for that!|
