I began riveting the vertical stabilizer rear spar, stiffeners, and hinges.  There were a number of different rivets called out by the plans for the rear spar depending on their location.  The lower rivets were to be flush on the forward facing side.

I used the pneumatic squeezer to set these ***4- rivets.  I initially set the air pressure for the squeezer at around 90 psi.  However, these 4- rivets set fairly hard.  I ended up bumping the pressure to 100 psi and I now usually run squeezer pressure between 100-110 psi for any rivets I am setting.  The pneumatic squeezer, however, did a very nice job of providing consistent shop heads.  If you are SLO-BUILDING, don't do it without buying a pneumatic squeezer.

This was the first time that Tami and I attempted to buck rivets.  Tami bucked while I ran the rivet gun.  I gave her a short lesson on the finer points of riveting.  We tried one just so she could see how it worked.  It turned out really nice, so we kept going on the rest of the skin.

We followed Van's instructions for riveting the skin to the spars and ribs.  Worked pretty well.  A jig would have been nice just for holding the stabilizer so that we could rivet.  We had two rivets that were high as a result of improperly holding/bracing the stabilizer during riveting.  I drilled those out and put a new rivet in with no discrepancies.

Now that we have the stabilizer put together, I wonder if we should have primed the skin as well.  I have searched a number of web sites of fellow builders and there are very few who are priming the skins too.
