Brief Description:  Rudder Assembly - Part 6

Before I started riveting tonight, I noticed a bend in one flange of the main spar. I don't remember this happening, but I suspect I wasn't carfeul enough while I had the spar clamped to the edge of the bench when riveting the hinge reinforcement plates. After lifting the skin, and spending a few miniutes massaging the flange with my flanging tools, I got the flange straightened out.

I then set all the skin rivets on the main spar, and all but one on each side of the bottom rib. I used the longeron yoke to set the aftmost three rivets inside each side of the rudder brace, but it wouldn't quite go into the forward corner. I think I can reach it with the no-hole yoke with about a half inch long homeade set taped to the end. I have some half-inch dia steel rod I think I can use for the purpose.

I set the aft most rivet in the bottom rib with the "indirect backriveting technique" I mentioned in the previous entry. I had to crank the gun pressure up to about 60 psi to get results. The heads came out a bit proud, but was able to flush them with the squeezer and no-hole yoke. I've had a similar problem in the past when backriveting stiffeners on the bench, so when I try this on the tip rib, I'm going to set up on the floor and see what happens.

Rivets this session: 132
