2 hrs. fitting the fiberglass tip to the left wing.

Sanding down the trailing edge of the tip in order to fit.

Found two un-riveted holes in the spar (not something I riveted).  Wasn't able to get the pneumatic in there, but was able to do them by hand.  It's the two on the far left bottom of the spar (the only two rivets done the other direction).

Multiple fittings to make sure it was in on the top and bottom the proper amount - not too far and not too shallow....  I measured the distance from the skin edge to the end rib and marked that on the tip at various places to help get it right.

Measured the angle (1.05 deg) to make sure I have the same angle on the other wing when I do that.

My procedure was to drill with a slightly small drill bit (to avoid too much grinding of the skin because it takes several seconds to get through the flexible fiberglass) and then exact size it with a chucking reamer bit.  That worked very well.

All of the top holes are done and about a third of the bottom holes.  I'll need to move the wing in order to get a drill under there so I can finish them.  Meanwhile I can't rivet it until I figure out the nav/pos light fitting issue and do that installation (and wiring of course).

NEXT TASKS:

1. Rivet the one on the step rib that needs special handling.  OK, I've been putting this off..
2. Light installation after I figure out the "hole" issue...
3. Tip riveting.
4. Composite filler for join between wing tip and skins. Perhaps other seams can use some filler?
5. Put the aileron and flap on the wing to check for straightness of the trailing edge (Thanks Peter, I saw that on your blog! ;-)). Based on what I'm reading online it seems likely that I'll need to re-rivet some of the aileron/flaps to line up the trailing edges...  Wish I knew this before I had riveted them...
6. Finish right wing.
   
7. Finally finish one of the composite tips of the elevator.
8. Fill rivets of elevator with Bondo.
9. START ON FUSELAGE!
