UPDATE: The pictures below are correct, so I will be riveting them tonight!

1 hr. sorting out the wing jigs.  Seems like the jig arms were mislabeled, so that threw me off.

Did I get it right?  Once I'm convinced it's right, I'll rivet them, bolt them to my benches and make sure they are level with each other to within the precision of the level.

The right jigs (?)  Root on left and wing tip on right.

The left jigs (?)  Root on right and wing tip on left.

At this point I've decided to go with the Vertical Power VP-X power controller system.  See more on my Avionics & Electrical page.

3 hrs. today priming most of the remaining wing parts, including the spars.  Also cleco'ed together the wing jigs.

I finished my video of the complete part prep process.  I show myself spraying the spars only once or twice, but I actually sprayed them multiple times per side to make sure I had complete coverage.  Turned out great.:



Parts on the rack and the longer ones on the tarp ready for the spray gun.

I found that the wing jigs which have the "right" parts seem to be for the left wing and vice-versa.  Until I figure out if I did something wrong I won't rivet them.  This is a photo of the root jig with the "right" labeled parts, but it's clearly for the left wing because the part sticking out is supposed to connect to the main spar which is in front.  Is left and right opposite in South Africa? :-)

2 hrs. finishing the cleaning of parts, including the wing spars.

Parts hung up and ready for priming.

Me cleaning the spars.

1 hr. tidying up and reorganizing the workshop (I need an orderly and clean space to work or my progress slips... I just don't like a disorderly workspace.) and 1 hr. cleaning parts for the 1st time using my new approach of Extreme Simple Green.  I use a 3-to-1 ratio of distilled water to the cleaner.  Works great!  Way better than the toxic stuff I'd been using.

This is before cleaning.

And this is after.  It's subtle, but you can see it's shinier.

2 hrs. deburring parts.  Tomorrow will be cleaning and priming, then onto the assembly!

Already primed parts on the right and the wing spars up on the table and ready for deburring.

4 hrs. today finishing up the wing rib sub-assemblies and starting the prep on the remaining wing parts.

Notice the rivets that must be riveted from the inside (as per the instructions).

Hmm, two holes on Wing Rib 8 that don't have matching holes in the part behind.  Drill through and rivet?

Torquing the hinge nuts.  AN4 bolts need 85 in-lbs, but you need to add the friction drag of the nuts.  I estimated (not sure how to measure it...) that to be 15 in-lbs, so the total set on the torque wrench was 100 in-lbs.

Nuts marked!

Wing Rib 8's finished!

Uh oh, seems I have two left parts (WG-CHL-007-L-C-0), not a left and right.
