We finished the horizontal stab yesterday (11/2). Riveting the skin to the rear spar went very quickly with my wife putting rivets in the holes and me coming along behind her and squeezing--the rivets!
This brings up a question: how's my pacing? I have 154 hours into the project. That's time with hands on metal and doesn't include time here researching or making trips to Harbor Freight/Lowes/Home Depot/etc. And that's essentially over 6 months. (Kind of over 5 months since life got in the way in Aug and I only had 1 day with any time on the plane.)
Off to pull parts for the elevators.
