Fabricated FL-706A's; Dimpling, Deburring Flap Parts
Here's a piece of angle stock Van's gives you to make the FL-706A's for both flaps. Here I marked the first cuts to make on the bandsaw.
I didn't get any intermediate shots, but here's the FL-706A and FL-706B after being match-drilled to the flap spar and inboard rib.
Then I pulled the pieces and deburred/prepped them for priming.
Here you can see the bend that has to be made. I ended up having to bang it some more in the bench vice before they would fit properly on the spar and rib.
Then I got tired to looking at the left wing with the access holes open and decided that I would sit for a while and install the nutplates for attaching the plates. After a bit of drilling/countersinking/dimpling, etc. the plates went on.
And here you can see that I removed the alcad from this access cover. The reason is because there was some sort of funky substance on there. I'm not sure what it was...but it looked like corrosion...so I scuffed it down until I could see no more corrosion. I'm going to keep an eye on this and if it comes back, I'll probably fabricate another access cover. It sould be trivial.
I'm not going to polish my airplane so doing this is no big deal to me.
Jaime came out and took this picture of me countersinking bottom flanges of the flap spars for the skin attach. The plans have you countersink the spar, dimple the skin and leave the hinges untouched, since the hinge material is pretty darn soft and dimpling it deforms it quite a bit because it's so thick.
Next I started deburring/dimpling parts. Here's the flap hinge after being deburred. LIke I said...you don't have to dimple or countersink the hinge.
Then I duburred and dimpled the spars.
Then the ribs for the left flap. I got tired and decided to go inside and spent some time with Jaime. To give you an idea of how long this project really takes, I worked for eight solid hours on the RV today. The only break was to eat a quick dinner with Jaime and that was it!
On an unrelated note, I just checked my fuselage shipping status and it's at the distribution center here in Atlanta!! I could possibly go down and get it but the shipping company closed the distribution center near my house...so the kit is on the Southest side of the city. It would probably take me an hour to get there, so it's really not worth my effort. I would rather spend tomorrow trying to at least get the flaps primed!
