Task: Front Deck
the front deck assembly done was todays task. I had previously
neglected to finish the F-721D brackets due to the difficulty
drilling at such a tight angle. I wanted to wait until the panel
was in-place and the whole front deck assembly was secure. First
I tried to drill into F-721A with an angle drill, but that didn't
work. The panel is in the way of the drill head. So what I did
was clamp the F-721D to the panel and then use the drill to
just mark the position of the hole. I then removed the panel
and drilled using the marks. This metho actually worked pretty
well. Once clecod in place, I could use the panel as a guide
to drill a #19 hole through F-721D for the #8 screw.
brackets were finished, I started the very last piece of the
fuselage kit yet to be fabricated, the F-703B angle. It is essentially
a 3/4 x 3/4 x 0.63 angle that gets corrugated to bend around
the top of the panel. It adds substaintial support to the panel
for rigity and stiffness. The reason it is the last piece to
be fabricated is because it is a pain in the rear! First I had
to measure and cut the angle to length, then I used my caliper
to measure and mark about 30 different lines where the metal
gets cut. The red marks are shown in the picture below.
the metal was marked, I drilled #30 as close to the vertex as
possible. The 1/8 drill bit will create the 1/16" radius
called out in DWG 24A. After all the holes were drilled, I marked
angled lines from each hole to even sides of the centerline,
at approx 15 degrees.
After 15 minutes on the band saw, here is the end result!
