Starting work on the Rudder

Today we started work on the rudder.  We first manufactured the rudder stiffners and then match drilled them to the rudder skins.  The edges of all skins and stiffners were deburred as were all the holes.  Next we dimpled the stiffners and skins.  We then primed all the parts, let them dry and then riveted the stiffners to the rudder skins.  We basically compressed all the building steps into a single day.

We had to create two rudder stiffeners out of every piece of metal you see sitting on the table.  Scott is marking each piece for future cutting/trimming.

 The stiffeners have been attached to the rudder skins and Darren has begun drilling out the pre-punched holes.

Where we finished for the day. both the rudder skins are primed and the stiffeners are riveted into place.

We had a pretty good run today, and only a few left over pieces......

Finished Vertical Stabilizer

Tonight we finished the assembly of the vertical stabilizer.  It went quickly since we finished all the preparation and assembled the skeleton in February while we were waiting for the missing parts from the horizontal stabilizer.  It's nice to have two major parts of the empennage finished.  Next up is the rudder.

The first thing we needed to do is take care of some riveting on the rear spar we put off due to a rivet shortage.

Next we set the rear spar aside, and focused on attaching the skin to the front spar and ribs.

This is a shot of the skin attached to the front spar and ribs ready to be riveted.

Same as the picture above different angle. 

Now we take a pretty big jump ahead.  The skin has been attached to the front spar and ribs.  Scott is now using the rivet squeezer to attach the skin to the rear spar. 

Almost done.  Darren is using the blind rivet squeezer to rivet the rear spar to the middle rib of the VS.

Finished Horizontal Stabilizer

Today we finished assembling the horizontal stabilizer.  We riveted the right side of the stabilizer, installed the rear spar and finished riveting the skin.  The horizontal stabilizer is finished for now.

All the mid-ribs are in place. 

Time to attach the rear spar. 

Have we mentioned a lot of time is spent with cleco pliers in hand?

A little team work on the riveting.

Horizontal Stabilizer Assembly Progress

Today we spent another 6.5 hours working on assembling the horizontal stabilizer.  We used our new pneumatic rivet squeezer (as an aside, it's the greatest tool!) to assemble the spars.  We also riveted the nose ribs on both stabilizer halves and finished assembling the left side of the HS.  We started work on the right side and decided to call it a day.

A shot of the clock, just because with the pneumatic rivet squeezer we managed to accomplish in 20 minutes what previously took us much much longer.

Scott still riveting.

All of the nose ribs have been riveted into place, and a couple of the mid-ribs have been cleco'd into place.

Same idea, but a different angle.

Attaching the mid-ribs to the spar is our first use of a blind rivet.

The state we left things in for the day.

Start of Horizontal Stabilizer Assembly

Before we started assembling the horizontal stabilizer we countersunk a few last holes on the leading edge of the front spar.  Once that was done (and we finished priming), we started assembling the rear spar.  We're looking forward to the arrival of the pneumatic rivet squeezer since squeezing the rivets by hand is very tiring.  They seem to get harder and harder as we move along...  

There won't be an update for a few weeks.  Work will resume on March 18th and we'll "make up" the lost days over the Easter long weekend.  For those who have asked, we'll be trying to add more pictures to the site.

I apologize for the  shortage of pictures. My camera stopped working about a month ago, and then I just managed to get really busy with other stuff.....  

About half of the parts we had primed this batch. 

The other half....  

The HS rear spar, the next part we will be working on.

The rear spar is cleco'd together and ready to rivet.

Now to cleco together the forward spar.

The forward spar is all cleco'd together and ready to rivet together.

By the look of the drawings all we need are some AN426AD4-6 rivets, and we can get going.

 Hmmmm......

I guess we will order a few more AN426AD4-6 rivets and work on something else for a bit.

Finished Horizontal Stabilizer Prep

Today we match drilled the right horizontal stabilizer, counter-sunk the #40 holes in all the HS spars, deburred all #40 holes (#30s were done before).  Afterwards we dimpled all the parts, preped them for priming and primed all parts of the horizontal stabilizer,
