Horizontal Stabilizer Front Spar

Got the font spar to the point where it’s ready to be scuffed and primed. This was way more work than it looked like in the plans. It all started with the spar caps. They had to be trimmed and deburred. Then they’re match drilled to the spar web. Then disassembled, deburred, reassembled. Then they are match drilled to the spar flanges, disassembled and deburred. There were approximately a million and one holes drilled and deburred in these things.

Then on to the spar doubler. The usual drill (no pun intended)… Deburr edges, fit, cleco, final drill, disassemble, deburr holes.

Countersunk twelve of the holes on the doubler.

Began back riveting the stiffeners into the skins but it’s loud and it got late so I quit until tomorrow.
