Right Wing Pushrods; Drilled Right Flap Hinge
This afternoon after work I went out and continued messing around with the pushrods. I installed both the long and and short pushrods in the right wing...except for the nut on the aileron. It seems a bit impossible to reach the bolt with the aileron on the wing. The plans have you put the bolt head pointing inboard and the nut outboard. Well, the nut is impossible to reach. Seems like the easiest way to do this is to bolt the pushrod to the aileron before the aileron gets attached to the wing. I'll do that on the left wing...and I may end up removing the aileron from the right wing and doing it like this. Why fight with it when there's an easier way?
Oh well, with everything together (except the nut where the pushrod connects to the aileron, of course), you can move the long pushrod and aileron of course moves back and forth. It's very, very smooth.
Next I decided that there was no real reason not to work on getting the flaps attached. I would rather do that before continuing to play with the pushrods. I first set the flap up on the wing to ensure where I wanted to drill the hinge...then I marked the hinge location on the wing, removed the pin and drilled the one half to the wing.
Ok, this varies slightly from the plans in that I'm reinforcing the hinge pin. I'm doing this because I'm having to dimple both the skin and the flap brace and I'm having to countersink the flap brace. Anyway, I took a picture of this to illustrate an excellent way to match-drill components. I like to do it on a block of wood...in this case an old 2x4. The neat thing about this is that you can cleco into the wood and it holds the material you're working with very firmly.
Here you can see the hinge reinforcement strip. I didn't take it all the way out to the end of the hinge, since the hinge actually overhangs the wing slightly.
Then I got frustrated at the mess in the garage and loaded up the fuselage crates that were still sitting around. Yesterday the in-laws were at the house for Easter and my father-in-law offered to dispose of my wing crates for me. Apparantly his trash company is more easily persuaded than mine. Mine won't even take it for extra money.
Anyway, another source of frustration is the flap brace that I neglected to countersink before riveting on the bottom skins. I tried squeezing them with my vice grip dimpler but had no luck, since it takes massive force to dimple the thick material in the flap brace. Hmm....frustration mounts....
I'm thinking I may end up having to drill out the flap brace rivets (ouch!!) countersink the flap brace then replace all the rivets with pop-rivets. I believe pop-rivets are acceptable here since that's what is done on the quick build wings...but boy...I do NOT want to drill out those rivets. What to do..what to do...???
