Tweaked Right Longeron
This morning I set my alarm and got up early and went out to the garage to work on the project. For some reason, my aft canopy decks weren't lining up. I knew that I got the bend within 1/32 of the template, so I couldn't understand how it was happening.
Ok, here you see the deck, and notice that with these two clecos the forward end of the deck is about a half-inch off.
Here's a closer view. So, I commited the drill to rivets and....
An hour later the longeron was out.
But when I sat the deck on the longeron...everything lined up beautifully...so what gives? I surmised that the problem could be that the longeron was bend inward a bit and pushing everything outboard.
Yep...that's the problem. The forward end of the longeron is on the lower left of the picture and you're looking at the top. The problem is that the longeron should be straight across but down here so that was obviously the problem. So, I clamped the longeron and in the vise and banged on it until it was straight.
And voila! That was the issue. Everything lines up perfectly now, so I re-riveted the longeron into place.
In the afternoon we went to the airport for the Post-Oshkosh bash that EAA 690 puts on every year. It's a lot of fun and they cook burgers, etc. We had about 75 folks there...which is typical when we're cooking dead cow. Mike Stewart was out there working on his 'Super -8', which is an RV-8 with an IO-540. He did his second engine run and, let me tell you, that was one of the most impressive run-ups I have EVER seen. It was moist outside and the pressure from the prop was condensing the water and the water was spraying everywhere. I went around behind the plane to check the tiedown and it felt like walking through a shallow, swift stream that wants to sweep you off your feet. As I said, very impressive!
When we got home at about 8:30 I went out and cut down one of my sawhorses.
Then I lowered the fuselage down to the lower sawhorse. I'm not sure I like this height for working on the fuse. I may come up with it about 6 inches or so. Anyway, as you can see from the picture, I threw a cushion in there and Jaime crawled in to try out her seat. As you can see from the picture, she likes it!
