Below, I am drilling the A-408 spar reinforcement plate.  Of course, these are not labeled when in the kit.  The "squares" were in the brown bag of parts that comes with the wings kit.  I lined up the reinformcement plate with the edge of the spar and cleco clamped into place.  All the spar reinforcement plates are the same (until you drill them) so it doesn't matter which one goes where.

I didn't do a real good job of shooting pictures here, but the inboard and outboard aileron brackets are mounted to the aileron spar with AN3-4A bolts.  This requires that the holes be drilled on the bracket, spar, reinforcement plate, and rib to a #12 hole.  Van's ships these brackets with #30 holes.  Therefore, you have to take the bracket from #30 to a #12.  The trick is that these are steel and do not drill out nearly as easily as the aluminum parts so here is what I did:

• Drill out the aileron brackts to #12 in two stages using the drill press.  First I drilled the hole out to a #22.  Then I drilled the hole out to the final size of #12.  Debur bracket holes.
• With all the remaining aileron parts (reinforcement plate, spar, and rib) clecoed in place, I drill those out to a #14.
• Then I clecoed the aileron backet onto the reinforcement plate, spar, and rib and match drilled everything to final size of #12.
• Checked fit with a AN3 bolt.

The problem would be....  If you try to drill all these parts at the same time, it will be very difficult.  The steel brackets are not the easiest to drill.  Just drill them in multiple stages, use a lower drill speed, AND lubricate your drill bit while drilling or risk dulling your bit on the first bracket.  I used WD-40, but just about any light oil would work.  Just clean off your bracket when done.

Voila, 20 minutes or so and all the brackets are drilled and look great.

I decided that I would start prepping the aileron stiffeners and skins for priming.  There are 32 stiffeners and two skins to prep and get ready.  I haven't primed any parts for almost a year (looking back at my log entries).  However, I didn't appear to have forgotten how to do this.  Priming this plane with the AKZO epoxy primer has been a very time consuming aspect of this project.

I got a system worked out after a couple of stiffeners and things trucked right along, but that is still alot of scrubbing....

Almost 5 hours to prep these parts to have them ready to spray epoxy primer.  I made a conservative decision and decided that I would not try to start spray primer tonight.  By the time I got this far, it was 10 pm.

Aileron skins have been scrubbed with alumiprep and given an alodine bath.  Ready for primer....

While cleaning up the garage for the night, Auburn's fireworks show was still going on.  I shot a couple of picts to see if they would turn out.  Not to bad, considering that this is just a $300 point and shoot camera.
