Task: Assembled parts
Today was very productive! I was able to nearly finish the forward
deck sub-assembly. There were several small angle pieces that
needed to be drilled to support the main panel. I also cut the
F-745 main ribs to allow them to move horizontally from their
original position. The EFIS screens are centered on the pilot
and copilot view which is directly where the F-745 ribs are
located. My plan is to move them inboard of the EFIS screens
and just outboard of the center radio stack.
To start things off I clamped and drilled the F-721C angle with
a 5/32 bit per the drawing. I then enlarged the hole in the
panel and F-721C with #19 for a #8 screw. Next I clamped and
drilled the F-703C angle to the sides of the panel.
Here is a
rear view of the F-703C angle and F-721C angle drilled to the
panel and F-721A forward deck.
angles were drilled to the panel and forward deck, I was able
to drill the MS21051-L08 one-leg nutplate to the F-721C.
I used a long piece of angle to keep the panel stiff while I
drilled the angles to the forward deck.
Here are the left and right forward halves of the F-745 ribs.
Before cutting them I drilled several angles to the ribs so
the spacing was set correctly.
Here I reclecod the subpanel assembly in place after cutting
the forward sections of the F-745 ribs off.
Next I worked on the battery box. We riveted the steel angles
to the box last week but still had to fabricate the F-7127C
retainer strap. I first cut it to length and then drilled the
two #12 holes on the ends using the batter box as a guide.
Then I drilled 6 lightning holes in the retainer. I also fabricated
the F-7127D doubler for the master/starter relays.
