Vertical Stabilizer

Hours: 5.3
VS total: 14.2

Cleco’ed VS skin to skeleton.  Match drilled and then removed skin and took apart skeleton.  Deburred everything.  Marked some holes to remain un-dimpled. Dimpled ribs (except marked holes).  Began dimpling skin – about half-way there.  Accidentally dimpled a few holes in a rib that shouldn’t have been and was relieved to learn they could be un-dimpled (searched VAF before and found I could squeeze with flat sets to un-dimple, but only once).  Had lots of help from Scott today.  He did much of the deburring of the skin and also served as a second pair of hands when cleco’ing the skin to the skeleton.  Our daughter Audra came out to help for a while, too.

Audra pointing out what the airplane is supposed to look like.

VS skin cleco’ed to the skeleton.  Some pain was avoided
thanks to those who warned about grinding down a small part of the front ribs.

Finally, we have something that resembles a part of an airplane.

Neat look into the Vertical Stabilizer.

Dimpling the VS skin.  Notice the blue strips that have been removed.

All taken apart again.

Deburr rear spar doubler and top rudder hinge doubler.  Cleco hinges onto rear spar, final drill parts attached to rear spar and countersink.  Page one complete.

12/20/2010 – Todd Stovall graciously gave me a tutorial at his house
on the art of aircraft construction.  Thanks Todd!

12/21/2010 – Closeup of real spar doubler.  You can see some of my nice countersinks.  And you can see the marks where I deburred the interior cutouts.  It looks jagged, but it’s actually quite smooth to the touch.  The reflections from the overhead lights make it look worse than it really is.  But still, it is uneven.  That’s what happens when you try to use a wheel that’s too big for the hole and only parts of it get done while other parts are untouched by the wheel.  In the end I used a deburring hand tool.  I think when it comes apart before priming I’m going to go over this again, but this time with a small scotch-brite wheel attached to a dremel.  I know it’s fine, but it just looks terrible.


12/21/2010 – a shot of the rudder hinges cleco’ed to the rear spar.

12/21/2010 – You can see the one and only hole that isn’t quite right.  The spar tipped while I was drilling and I made this small gouge.  I’ll look at it more closely when it’s time to rivet and possibly drill it larger and put in the next size up.

with the rear spar and the top hinges.
