While I was working on wrapping up the rudder, I got to work prepping parts for the Horizontal Stabilizer.  I got both spars and spent a lot of time getting them all deburred.  These spars are about 11 feet long, so I built a couple table tops to put on sawhorses (1 2'x8', 2 2'x4') so that I can have options to reconfigure the work table.

The rear spar is pretty straightforward, there are some hinge brackets and doubler that get riveted in place.  I got everything drilled, and primed and my dad came over to work with me.  This was his first time to work with me on the plane, and we had a good time.  We got all the rear spar riveted together including the inner bearing/bracket.  We got a start on the attach brackets, but then called it a night.

The next step was to complete the fabrication of the attach brackets.  These are cut out of a large piece of aluminum angle.  Not having a belt sander, I rough cut the pieces then used a vixen file to bring them to final dimensions.  The second bracket I made turned out a lot better than the second.

Next there were six pieces of aluminum angle for stringers and caps that needed to be cut to a taper and deburred.  I bypassed the bandsaw and used the aviation snips, getting a forearm workout on the thick metal in the process.

The HS-1013 spar cap gets marked and clamped into place, drilled to the web, deburred, re-attached, drilled to the flange. etc.  This takes quite a while with all of the hole deburring, drilling and waiting on my wimpy little compressor.

I completed the drilling of the spar caps, and temporarily fastened the spar doubler.  This was when I started to realize that I had made a mistake earlier in the day.  After the doubler is attached the attach brackets I finished earlier in the day are fitted to the doubler and spar assembly.  Looking closer, I had mistakenly swapped the size of the holes on the attach brackets.  The means that the 1 hole needed to locate the bracket to the doubler was over sized, and I get to make a new pair of brackets.

I will order the part from Van's on Monday, and work on it when I get back from Vacation in a couple of weeks.
