After some remaining work on the rear spar, assembly of the front spar. This proved more difficult than anticipated, mainly due to wrong handling of the pneumatic squeezer. I got lot of rivet removal training!!!! The spar is finally complete and the remainder of the day, I worked on the vertical stab.

Today I made big progress, at least visually. The morning was devoted to priming all the parts. This step went quite well considering working with a paint gun was a first for me. Although a professional painter would not be as happy as I am with the result.
The paint and the gun are quite easy to use, I chose a HVLP gun which reduces painting mist and runoff risks.



Then another big step, the first rivet : it's painted orange just to remember it.



Then I assembled the rear spar, Guillaume squeezed a few rivets.



And here is the finished spar.

The vertical stab has been primed at the same time as the horizontal stab, for more information see this entry.

All the parts are now ready for priming after sanding and washing.

Today I fixed the problem of the oversized hole. Following Van's advice, I cutoff the rib's flange and replaced it with a new fabricated flange that will get riveted to the rib's web (as seen on the picture with four rivets : probaby overkill).



Then the whole horizontal stab. got prepared for priming : deburring and dimpling.
Sabine came to help with deburring the skins.
