Brief Description: Right Wing Leading Edge Rivet
|
|
Well, spend Thurs & Friday up in Kansas again, this time moving #1 son back down to Ft Worth. Quick trip up and back. Not much got done earlier in the week, either, since I had to do some prep work in other areas to get ready for the trip.
One of the reasons I've been slow to close the right wing box is that I really didn't know what I wanted to do WRT lights / strobes. I'm a private pilot, and #2 son is commercial / multi / IFR, so I really wanted minimal night capability. No idea if I'll need 4 wires, 3, or 2 at this time, so I decided to just run conduit. Some builders have used the CPVC pipe that's 5/8" OD and 1/2" ID, drilling out the front tooling hole in the nose ribs to hold it in place. I got to wondering if this would create any structural issue, so I asked Kerry at Sonex. He said that 1/2" is OK, but he'd prefer not to take them to 5/8". Then he added that CPVC should not be used, as it's too rigid. Suggested I use the milky-white flexible water line. So it was back to the Aviation Dept at Lowes to return the rigid CPVC and get the recommended product.
Up-drilled the tooling holes to 1/2" and ran the lines.
Then, positioned and cleco'd the leading edge skin. Decided to start with the bottom side of the wing (since it was still facing upward after the aft skin install). Riveted it to the main spar (CCP 44's), then riveted the skin to the ribs using CCC-42 flush rivets.
Flipped the wing over with the help of #1 son and using ratchet straps, pulled the skin into position, cleco'd it to the main spar, then cleco'd the skin to the ribs. Making great progress, but being the holidays, had to stop early so that I could attend a Christmas party. Those priorities again.....
