This will be a long post as I haven't done an update in a long time.  When I left off I was working on the Horizontal stabilizer spars.  I built the cradles for the skins, and realized that I made them way too tall.

once I got the front spar parts all match drilled, I primed them and started the process of riveting the doubler, spar caps, and attach brackets in place.  I botched up one of the rivets on the attach bracket.  I will have to fix that later.

With both spars riveted, I started the assembly of the whole stabilizer.  Like on the vertical stabilizer, the nose ribs are difficult to get in place, but I think these will go a lot better.  I really didn't have all the clecos I needed to get the skins in place and as tight as I would like it.  

In order toget good alignment to do the final drilling, I wound up moving a LOT of the clecos around, and getting a sore hand in the process.  My pore little compressor can barely keep up during the drilling process, so moving clecos around didn't really cost me a lot of time.  I have since acquired 200 more 3/32" clecos.

After the process of drilling the skins, I disassembled the stabilizer and started the long process of deburring all of the parts, then countersinking and dimpling the skins.  This is an incredibly long, and tedious process.  I worked on it a little every night.  I had to get some help dimpling the skins as they were really too long to support one end, while the other end was in the C-Frame.

I have all but given up on using the Sherwin-Williams primer.  I have not had any luck shooting that primer, but the self etching rattle can primer goes on and covers very well.  I primed all of the parts, and the skins where they mate with the skeleton.

Here you can see the center section of the stab cleco'd together before I start riveting.

Completed center section.

Next all but the two most outboard inspar ribs were assembled to the front spar, and riveted in place. 

Before calling it a night, I set the cradles back up and clecod the nose ribs in place.  Next I will rivet these to the skin, then start assembling the complete assembly.
