I have finally started drilling out the holes in the firewall. These have been A3 size since the initial assembly just in case I needed to adjust something when working on the rest of the fuselage.

Today I noticed a small amount of corrosion around one of the clecos on the firewall, so it was decided to drill everything out, deburr, acid etch, scotchbrite and then zinc as soon as possible.

All of the holes ( save the engine mount bolt holes ) that lay in the horizontal plane are drilled.

Fuselage ~219h ( 3h, 3h, 2h, 3h, 7h, 2h, 5h, 2h, 3h, 2h, 2h, 3h, 6h, 2h, 2h, 1.5h, 2.5h, 1h, 2h, 3h, 2h, 3h, 4h, 1h, 2h, 1h, 3h, 4h, 3h, 3h, 4h, 3h, 4h, 4h, 6h, 3h, 3h, 4h, 2h, 2h, 2h, 4h, 2h, 2h, 10h, 4h, 4h, 6h, 3h, 4h , 6h, 3h, 2h, 2h, 5h, 2h, 3h, 3h, 2h , 2h, 3h, 4h, 1h, 1h, 1h, 1h, 3h, 1h )
Wings: ~157.5h ( 1h, 1h, 0.5h, 2.5h, 4h, 1h, 1.5h, 1h, 1.5, 4.5, 1h, 1h, 2h, 4h, 1h, 3h, 1h, 2h, .5h, 1.5h, 2h, 2h, 2h, .5h, 1h, .5h, .5h, 2h,3h, 1h, 3h, 3h, 4h, 2h, 3h, 7h, 3h, 1h, 4h, 1h, 1h, 1h, 4h, 2h, 2h, 2h, 2h, 1h, 2h, 3h, 2h, 1h, 3h, 2h, 2h, 1h, 2h, 3h, 2h, 1h, 1h, 1.5, 2h, 2h, 3h, 2h, 1h, 3h, 2h, 1h, 2h, 1h, 5h, 2h, 1h, 2h, 4h, 2h, 3h, 3h, 3h, 2h, 3h, 2h, 3h )
Flaperons: ( DONE! ) 23.5 hours spent ( 3h, 1h, 1h, 1h, 1.5h, 3h, 6h, 3h, 4h, 1h )
Paint Design: 2 hours spent ( 1h, 1h )

Horizontal Stabilizer DONE!: ~28 hours spent, 3 pieces replaced ( 3h, 2h, 2h, 2h, .5h, 1.5h, 3.5h, 1.5h, 5, 4.5, 2h, .5h )
Rudder DONE!, minus horn : ~16 hours spent, ( ~8h, ~8h )

Do you have some sort of dissimilar metals thing going on there? Is this from having clecos in for so long?

Yes it probably is fro dissimilar metals. The firewall is steel, the parts on it are aluminum, and who knows what the clecos are made out of. So it probably is anode corrosion.

I still clecos in my top wing skins so I can finish wiring and fuel plumbing. A check of those clecos revealed no corrosion.
