Countersinking the spar flange so the rivets lay nice and flush.

Started the right wing.  Here I am match drilling the J stiffeners.

What to do with that old Vans spar crate?  Make a stage out of it, so you can get above the work with the drill and countersink cage.  Much easier than holding that heavy drill in front of you face for a couple of hundred holes!

Left aileron bellcrank installed!

Left aileron torque tubes going together.  No,  I did not scratch the powder coating.  That's excess primer that ran out from the inside.  It cleaned up well.
