Got a lot done today. My friend, John Wagner came over to help a bit. First we got the rear spar riveted together:

Notice the flush rivets near the bottom of the front spar.

Then, we also riveted the front spar and ribs together…

Afterwards, we spent the rest of the time deburring and dimpling the skin. I need to build a table for the C-frame still. The C-Frame table top would go over the bottom of the C-Frame so the skin doesn’t flop around. For now, I had help holding it steady. And then we finished up by clecoing the skin onto the skeleton. And here it is all ready to rivet the skin on.
