Task: Finished seat backs - Continued work
on forward deck
unexpectadly able to spend quite a large amount of time on
the project today! I got a lot accomplished which is always
a motivating aspect of the project. I started with the forward
deck which this week I finished several parts for. The seal
support was clecod to the whole sub panel assembly and the
I inserted it back into the fuselage. I match drilled all
holes and dimpled several of the parts. Other than the forward
top skin, the forward deck is almost complete. Next I moved
on to the F-7114 gussets and then the forward covers. See
descriptions under each picture.
The forward deck cleco'd back into the fuselage after the
seal support was fabricated.
Using 1/4 and 5/16 hardware store bolts, I installed the F-7114
forward fuselage gussets. In the -7A model, the landing gear
weldments would normally go in this place. In our case the
gussets just tie the lower longerons to the F-704 wing spar.
Once bolted in place I used the holes in the outter side-skin
to drill through the gussets. I started with #40 and then
opoened the holes up to #30. Once we install the wings and
the spars are in their final position, I'll open the holes
up to 1/4" for AN3 bolts.
The next big task to conquor was the forward covers. The F-782D
angle must be fabricated and drilled to the F-7101 doubler
plate. The problem is positioning the F-782D angle in place
and locking it in position once the forward cover is removed.
After a lot of headscratching I got the idea of using the
stiff piece of aluminum that was originally pop riveted to
the forward deck rails for temporary stiffening. The bar worked
perfectly because was extremely rigid and easy to clamp to
the Z-brackets. I used C-clamps to clamp the bar in place
and then another clamp to hold F-782D to the bar.
clamped I used an angle drill to drill the 3 mounting holes
drilled I marked the approximate location of the screw holes
to ensure I had the required edge distance.
I match-drilled the angle using the forward cover.
I opened up the screw holes for a #8 screw.
match-drilled I installed a K1000-08 nutplate and drilled
the rivet holes.
used my Dremel to make the cutout of the fuel suppl y line
are both F-782 brackets once finished. The nutplate rivet
holes still needs to be dimpled. That was it!
task: installed a nutplate for the forward cover in-between
finish the day off I installed and clecod the F-704K spar
cap. It basically acts as an aesethetic cap for the two spar
