I riveted the parts for the horizontal stabilizer front spar this evening. There are a wide variety of rivets in this assembly – check twice, rivet once. I was able to set all of these with the pneumatic squeezer.

I have averaged 5.5 hrs/week (0.79 hrs/day) and have about 469 hours remaining.

Some guesses as to how long it might take to finish:
• At my average rate (November 2026)
• At 8 hrs/week (May 2026)
• At 12 hrs/week (December 2025)
• At 14 hrs/week (November 2025)
