Installing the skins






















Today is June 3rd and we are on page 17-02 We got the stall warning indicator functioning; we had to bend the main tab of the unit in order to get it functioning while positioned in it's slot. We laid the main skins on the inboard, outboard, and middle sections. To begin, we used a soldering iron to reveal the holes that we'd be using for the rivets. You simply heat up the tip and drag it slowly over the areas that you want revealed and pull away just the area that you'll be working on; that way, the rest of the 'skin' will be protected. We also needed to lap the inboard skin section edges to in order to make them fit correctly; read the section that they direct you to so that you can understand the process. My partner came up with an idea on how to do it without buying the special tool; we laid the skin on a solid surface, allowing about 1/4 inch to overhang the edge of the table, and then we took a block of 2x4 and held it at a slight angle, and bent the edge slightly by running the wood along the edge. Incidently, up to this point we haven't used 350 Clecos at any one point in time; it might be important when we do the fusilage though. Our rivet gun failed us and we had to figure out how to fix it since the factory couldn't figure out the solution to he problem. We also weren't paying attention to the directions as we put some rivets where they weren't supposed to go, but we drilled them out and continued on. The two of us worked about 8 hours today, one of our longer days. I've got some before and after photos, along with one showing how we lapped the edges of the middle skin.
