Let's move!
I turned the center wing across the table to allow for installation of the
gear leg while working on the top of the wing. When I measured the
position of the two-inch hole (on left side of CW), I was happilly surprised
to see that it is perfectly in the middle. |

A strip first
The first thing I did is to make this strip (I forgot the part number, but I
think it is 6V5-something). I also pre-drilled it. To align
the hole of the top skin with that stip (while installed on the skeletion), I
temporarilly fixed this strip by drilling a few holes and attaching it (either
with flush 3/32 rivets or safety wire--a vigilant eye can see
both). Then, I installed the pre-drilled (for the three inboard
ribs) top skin and clecoed to the skeletion. I drilled a couple of
matching holes from the bottom (to locate the stip with the top skin). |
 |
Then, match the entire strip with the top skin
I disassembled the top skin and reinstalled it with the pre-drilled strip on
top. I clecoed the strip at its two match-drilled point (drilled from
underneath). Then, I drilled the remaining holes. |

Another Oups!
When I first observed this, I have been quite nervous about the positioning of
my gear leg.... but everything measured fine... The problem is that the
cap is welded at an angle with the tube. I will have to make a special
"stop plate" to ensure a proper fit with the wing. |

Installing the upper bearing

Just taking a break of the construction...
This was a fun morning... I had the chance to play with my brand new snow
blower. OK... not everyone enjoyed that day so much! |
 |
Are the gear box ribs still square?
One one side, yes. For the other side, I had to adjust the ribs by
removing two rivets from each of the L angles that attach the extrusions
together and by adjusting. I re-drilled the holes and re-riveted.
Now, the gear boxes are truly vertical. |
 |
The nose skin installed...
The technique used is very similar to what was done for the outboard wings. |
 |
... and cut...
I did remove the skin entirely to cut the opening. It is just easier
than trying to cut it in place.
|
 |
... and stored
After I deburred, smoothered, cleaned, primed and riveted on the bottom (nose
skin and spar), I stored it against the garage door. I now have enough space
to work on the rear fuselage. |
