Took a leisurely time adding the aluminum tip rib extensions for the fiberglass tips. Made sure they were aligned with the centerline of the wing. Had to run out and get some additional 2.5" clamps to help hold everything together for the drilling, since I had already drilled the tip rib into the aft spar as part of the initial buildup.
Couldn't resist cramming the fiberglass tips in there to see how they fit and lined up. Seem to fit better than the vertical stab tip (which I still haven't finalized).
Have decided that I'll rivet everthing except the tip rib rivets, plus 1-2 back from there to facilitate adding the fiberglass tips after the elevators are installed and the hinges installed and cotter-pinned.
test-fit of rib / no trimming
yeah, it's not aligned, but plenty of movement to make it fit later
