December 10, 2005 - Forward Fuselage |
||||||
A good look at the area where the side skin joins the aft skin and bottom skins. This is before curling the side skin, obviously. | ||||||
I took the side skins off to curve the aft bottom corners. The
instructions gives you pretty good direction on how to do it.
First I fashioned some aluminum angle and matched drilled it to the skin
corner. Then I clecoed the angle to the skin, with a cleco in
every hole. I clamped the skin to the workbench with some steel
angle. Then all you do is attach a vise grip to the aft end of the
angle and push with your thumb on the forward end and curve the thing.
|
||||||
After curling the skins, I turned my attention to the corner ribs. I
finally understand what the purpose of the "attach straps" is for. I
had made them previously but then ruined them by drilling holes in the
wrong location. So I had to make some new ones. No big deal.
All the "straps" do is connect the corner rib to the forward and aft bulkhead flanges. |
||||||
Then I had to trim the forward end of the corner ribs. I used my
trusty Dremel tool.
|
||||||
I clecoed the corner ribs in place
with the attach straps, then put the side skins back on. The key to
clecoing the side skins to the F-706 bulkhead is to cleco them from the
inside of the fuselage. It's difficult to cleco them from the
outside because the F-706 bulkhead flange moves and you can't see it.
Amazingly, my skin curls came out very nicely. Almost like I knew what I was doing! |
||||||
Then it was time to drill the longerons, starting from the tailcone and working forward. There are a lot of holes, and I'm drilling through 1/8" aluminum angle, so it got a little tedious. | ||||||
Must ... keep ... drilling.... | ||||||
The right side longerons are drilled. Look at all those clecos.
And there is only one cleco for every four holes. Do the math.
