Had a great day to work today! It was almost 70 degrees with a nice slow south breeze blowin'. I started by riveting the fork and plate on the right rear spar. The pic below shows the front and back of each of the rear spar inner portion that connects to the fuselage. There are several holes that do not get riveted at this point. They'll be used to attach wing ribs later.
I forgot to drill a few holes on the flange of both spars where the reinforcement plates attach. Did that and deburred those holes, then riveted the plates on both rear spars. The first picture shows how I gained access to the flange on the plates. They are very narrow, and the pneumatic squeezer yoke wouldn't fit in there. I had previously ground the yoke and female dimple die in the hand squeezer for something, and this came in real handy to dimple these flanges. I also had to do a little touch up priming where the dimples removed the paint.
You can see that I put the shop head on both sides of the spar. I don't have a longeron yoke yet, and these won't be seen. Plus, here it doesn't really matter which side the shop heads are on.
Then I began the dreaded task of deburring the wing ribs. This ain't gonna be fun...
Mmmmm ribs...
You can see the groove I've worn in the scotchbrite wheel from working on the edges of the ribs. It actually works nicely this way, in that it deburrs both sides at the same time.
