So I’m writing this almost a month later (so sorry) and it’s been kinda busy in and around the holidays.
I was excited to cleco together some big parts and get them matchdrilled.
Here is the first side of both HS skins being matchdrilled.

After drilling, I clecoed on the other part of the skins, and drilled its side.

Once the skins are solidly clecoed in place and stable, the inboard ribs go in place and get drilled.

A shot of the other side, too.

Once the inboard ribs were in place, I celebrated no mistakes and quit for the night.

2.0 hours on the horizontal stabilizer!
