Taking full advantage of the one day 30 degree heat
wave last Friday and the accompanying calm winds, a small batch of Akzo primer
was mixed for the airbrush so the two replacement F-1236A step angles could be
primed. In addition to priming the two F-1236A step angles, some additional
pieces which either had the primer sprayed a little lighter than optimum or had
been scratched were touched up as well. Mike’s two burner heater was doing a
swell job of keeping the shop well over 60 degrees so the epoxy primer was able to cure correctly. The parts were
suspended from bungee cords in front of the heater to absorb the warmth
radiating from the heater.

After the primer on the W-1236A step angles had a
couple of days to cure, all the F-1236 step angles were secured onto the F-1212
step ribs with Clecos and then riveted in place.

The F-1202F bulkhead received four nutplates
then the bulkhead was Clecoed onto the F-1212 step ribs for riveting. The pneumatic squeezer was used to set AN470AD4-4
solid rivets in the top two rows of rivets and the remaining rivet holes that
the squeezer could not reach received LP4-3 rivets with the exception of the
two flush rivets in the corners called out in the plans. There are also four
rivet holes the plans instruct the builder to skip, so they were marked with
blue tape.
