27 - October 5, 2008:
(8.0 hrs.)
My hangar is almost complete, and with the cold weather coming, I
thought it might be nice to move my wings to the hangar to make room for
my truck in the garage. Before I move the wings, I want all the
work remaining to be completed. Here I have begun fitting the wing
tips. This involved removing some material from the inboard
trailing edge to provide clearance from the aileron. I then
aligned the tips with the ailerons in their neutral position, and taped
things in place so I could begin match drilling the attach holes. |
 |
Here are all the holes match drilled and
cleco'd. |
 |
Next, I made some .025" aluminum strips to
act as reinforcement for the nut-plates that will be attached on the
inside of the tips.
Here I have match drilled the nut-plates to the wing tip and its
reinforcement strip along the top surface. Next the bottom surface
was done, and then the same was done on the second wing tip. Lot's
of nut-plates! I think 80 in total. |
 |
Next, I installed the wing tip ribs to
close out the area adjacent to the ailerons. I installed these
ribs 'reversed', to get a cleaner closed out surface. The only
disadvantage to doing it this way, is that you need to use blind rivets
to secure the ribs. |
 |
In the left wing tip I installed the Bob
Archer VOR antenna. It is attached under 4 of the wing tip nut
plates. I also laid some fiberglass up over a few areas of the
antenna to keep it flat (not shown in the picture). |
 |
Next, I enlarged the holes along the
outboard wing skins and dimpled them to receive a #6 countersunk screws. |
