I've stalled on the Horizontal Stabilizer for the time being because
I need an extra pair of hands for the riveting, so I decided to
start on the Vertical Stabilizer. Here is the rear spar with the
reinforcing bar and hinge brackets cleco'd inside. The rudder will
eventually attach to the hinges so it can swing freely.
are all of the internal ribs for the VS. I have fluted them so they
lay flat on the table and I've cleaned up the edges with the edge
deburr tool. This sucker is a lot simpler than the HS!
is a shot of the internal pieces of the VS all cleco'd together. I
have match drilled all rib-to-spar attach holes to final size.
I have cleco'd on the skin of the VS.
today match drilling the skin to the ribs and spars, deburring the
holes, cleaning up the edges, etc. After this I dimpled the ribs and
spars using my pneumatic squeezer.
This is a shot of how you typically drill through the pre-punched
holes in the skin and ribs to ensure they are exactly the same size
and are lined up.

Here I have countersunk some of the holes in the lower part of this
piece because when the whole thing is put together this surface will
lay flush against and attach to the fuselage. Because of this, the
rivets that go into these holes are flush head rivets and the countersunk
holes allow the surface to be flat and smooth after the rivets are
By the way the surface is just a bit dirty....it will come clean when
I hit it with laquer thinner before priming.
got around to priming the internal components of the vertical stabilizer.
Should be able to rivet these guys in the next few days (here's to
Here I have riveted together the rear spar of the vertical stabilizer.
The triangular thingamabobs are the hinges that the rudder will (someday!)
swing on. I was able to reach all of these rivets with my pneumatic
squeezer, which is a real timesaver.
This is a pic of the front spar and internal ribs of the VS. Here
the VS is "flying" to the right.
the skin is cleco'd onto the front spar assembly. Notice that the
rear spar isn't attached yet. In this way, the bucker can reach into
the assembly and buck the interior rivets while the shooter hits 'em
with the gun on the outside.
Here all of the interior rivets (that need to bucked) are finished
and the rear spar is cleco'd on. All that remains now is to set the
rivies along the edges which can be done from the outside.
Vertical Stabilizer is complete! I squeezed the edge rivets and
blind riveted the rear spar in place and now this puppy is done.
