Riveted all left rear spar components together. I had a two tricky rivets that had to be redone but everything else went well.

After that I started prepping the rear spar components.

Started on left rear spar: 9 hours

I got the left rear spar all the way to the point of riveting.

There was a fair amount of time spent reviewing the plans and researching techniques online. I think the right rear spar will go a bit faster.

I did all the edge finishing on the rea spar components, then I match drilled all the doublers to the rear spar. After I made some modifications (grinding) to the pneumatic squeezer I was able to dimple the appropriate holes on the rear spar and doublers. Then I scuffed and cleaned everything. Then primed all pieces. Tomorrow I will rivet it all together.

Making the clearance hole for the aileron pushrod in one of the doublers (the Dremel has been indispensable)

Worked on wing tie down brackets: 6 hours

Worked on match drilling the tie down brackets. This took a while due to lining up and drilling through the spacers.

I also drilled the spacers and tie downs for the plate nut rivets. Then I primed the tie down blocks.
