Bottom Skins Ready for Priming

Once I completed the antenna holes, I removed the bottom skins for deburring and dimpling.

Hannah helped me remove the vinyl along the rivet lines.

Lots of holes to deburr. Lots of holes to dimple.

I then dimpled the corresponding holes on the bulkheads and ribs.

The holes with rib tabs behind the bulkheads are countersunk as there are two layers there.

The holes on the aft bulkhead assembly are also countersunk.

Done. More parts ready for priming and riveting.
