From the last log
entry, I am now a week behind where I would like to be. This
last week has been something else. Always something distracting
me from working on the plane.
Sunday-
A shelf in our closet fell off the wall when I was putting laundry
away and took about half the drywall with it. Tami said she
was glad I did it instead of her. Basically said screw it
and Tami and I put 150 miles on the Goldwing since it was a beautiful
day. Rode to Omaha to the famous Nebraska Furniture Mart and
bought some DVD's.
Wednesday-
Had an airport authority meeting. Found out that the FBO where
I am taking flying lessons does not have a plane this year to rent
out as all the owners who were leasing their plane(s) back to the
airport don't want to do it this year. WONDERFUL, slight setback.
I wonder how many hours this is going to cost me to back track with
another CFI to get where I am now?
Thursday-
A friend of mine realized that I actually knew how to turn on a
computer and wanted me to re-load all of his computer software after
his kids trashed the OS after trying to "FIX" it.

This log entry is roll
up of the minutes I was able to spend putting up the wing stand.
I have been anxious to get the wing stand up so I can start assembling
the wing. I have about 100+ hours on the wings already and
don't have any major structures riveted together to show the results
of my effort.
My garage lights kind
of washed out this picture, but at the top you can see a 2"
x 4" (26" long) lag screwed to the ceiling trusses.
Once I had the 2" x 4" mounted to the ceiling, I attached
a angle iron (you can get at Home Desperate decking department)
to the 2" x 4".
I then hung a plumb
bob from the center of the angle iron to mark a point on the floor
where the back and center of the vertical 4" x 4" would
need to be mounted in order to be somewhat plumb.

I then
measured the center of the 4" x 4" brackets and placed
the back, center side of the bracket where the plumb bob pointed.
The 4" x 4" bracket was secured to the concrete floor
with concrete anchors.
When I was mounting the
aluminum angles that will hold the wing spar, I looked for any reference
on how high to mount these things. I could not find any info
to offer me a guideline of how high to go. I decided to mount
them aluminum angles pretty low. The top of the aluminum angle
is at 42 1/2". This will allow me to:
- Work on the aft side of the wing while sitting in a chair
or a the roll around seat (in the picture).
- Work on the forward side of the wing with nothing taller than
a short step stool.
I don't think the
height is all that important here or Van's would have given us a
dimension for mounting. 

With the
line level, I was able to get both aluminum angles at the exact
same height considering that my garage floor has about a 1/2"
difference in height from one side of the stand to the other.

Before drilling
the hole(s) to mount the aluminum angle to the 4" x 4"
post, I checked that the aluminum angle was level and then double
checked the line level. When everything indicated level, I
drilled the aluminum angle mounting hole(s).

One of the
first things that will be required after mounting the wing onto
the stand will be to take out any twist in the wing. For that,
I wanted some adjustability in the wing stand. For the aluminum
angle support hardware, I used two turnbuckles. Just turn
the center section (buckle) it will rotate the aluminum angle both
clockwise and counter-clockwise. With the smart tool, it is
easily adjustable to 0.1 of a degree.

I am
finished with the wing stand and tomorrow Tami and I are planning
on riveting the wing ribs to the main and rear spars. Should
be interesting. This is the first time we will be using the
rivet hammer with AN470 rivets. I would expect I will renew
my proficiency with drilling out rivets tomorrow as well. |
