Decent progress tonight! My goal was to get the right wing in its stand so I can start clearing out some space in the shop to work. I still needed to get the rear spar riveted onto the wing skeleton, so thats where I started. I clecoed the spar onto the ribs and made sure to note which rivet holes to leave blank as they are used to attach the flap brace and aileron gap seals. Once I got it clecoed on, I used the Numatx Squeezer to set all the rivets, being very careful to make sure I was using the correct length rivets. They are all AN470AD4’s but multiple different lengths depending on what all they went through. This squeezer made quick work of them!

Finally I had to dimple the few holes in the aft side of the wing tip rib so I could get the dimpled spar to sit nice and flush. We need to use some AN426AD4-5 rivets flush rivets in these holes because the aileron mounting bracket will rivet over top of them. I used my old pneumatic squeezer to get them dimpled. Here’s the squeezer dimpling the rib, and the next photos show the rivets nice and flushly squeezed.

We don’t rivet the wing tip rib to the main spar just yet, so I clecoed it in place and drilled some holes for the angle aluminum bracket I use to hold the main spar in the wing stand, all per Vans recommendations in the plans. I used some #10 screws in this angle aluminum and we need to back drill the holes into the rib.

I drilled the holes into the rib, and attached the bracket with some #10 screws, washers (both sides) and nuts. They don’t need much torque to do their job. With that completed, the wing is pretty much ready to be secured into the stand!

Now its time to get the wing stand ready. I did one last level checks on the brackets, and then stuck some electrical tape on the brackets to help protect the main spar from scratches. Then I moved the wings over to the stand and got them somewhat squared up.

Now, this is when I realize that I do not have any more 2″ or 1″ C-clamps to secure the wings into the stands, so I just had to make do for now….I used some wood clamps to temporarily secure the wing into the stand to keep it safe. I’ll make a Harbor Freight run to pick up some C-clamps and some bottle jacks to place underneath the middle of the wings to keep them from sagging. But, now they are both safely in the stands I can get my workshop cleaned up and organized a bit better.

Here’s all the photos from tonights session:
