(18-5 step 4): First up tonight is to fix that stiffener rivet I miffed up the other day.
|
(18-5 step 5): After that Angela & I prosealed and set the fuel cap flange rivets.
|
(18-5 step 8):
Next we applied proseal to seal the tank attachment bracket in
place. This time around we're going to go ahead and set the
rivets instead of letting the parts sit over night. With the tape
over the head of the rivets the rivet gun isn't affected by wet
proseal, and the shop head side is the same regardless... so we thought
we'd give it a shot.
|
Woops…
probably shouldn't have done that. Right after we set this rivet,
I started looking at it funny. Something just didn't seem
right. Then it dawned on me that the aft portion of the inboard
rib goes there, and this rivet is supposed to attach it as well.
Oh well, get to drill out another :-(
|
Ok, there… the tank attachment bracket riveted to the skin.
|
(18-6 step 1): Then I dabbed a little bit of proseal on the vent line snap bushings and popped them in all their holes.
|
(18-6 step 3): And
just before sliding the vent line in I realized it would be easier to
seal the rivets nearby prior to doing it. Once done, the vent
line was slid into place.
|
In order to get the vent line through the clip at the fuel cap flange it needs to be bent slightly.
|
(18-6 step 5): Now with the vent line in we could install the aft portion of the inboard rib.
|
This is the position of the rivet I just drilled out
earlier. The bucking bar just wouldn't lay right, so I wound up
folding this guy over… so I get to drill out another rivet from
the same hole! I used the squeezer to finally set this guy.
Believe it or not, I actually prefer the rivet gun when using
proseal... the squeezer is difficult to keep from slipping around with
the proseal.
|
The last thing for the inboard rib was to set the 1/8in
universal head rivets attaching it to the tank attachment
bracket. The center 4 were no problem, the outter two however, I
haven't decided how to buck just yet (there's not enough room on the
underside to get a bucking bar on them). Anyway, we'll come back
to these later...
|
So here's where we'll be stopping for the day. You can
see this end of the vent line will also need to be bent to line up with
the fitting that will eventually be placed in the inboard rib.
These shots also show why you have to put the vent line in PRIOR to
installing the aft portion of the inboard rib!
|
Nice… the clecoes are gone… but there's still a lot to go!
