Remove wingtip and smooth edges using vixen file and Permagrit tools.
Repeat fitting and trimming until wingtip fit was acceptable.
Install wingtip on wing.
Match drill wingtip using skin holes for guide and #40 drill. Cleco as drilled, working from front to rear and alternating top and bottom.
Temporarily install flap and aileron to check wingtip alignment. Left wingtip TE is approximately 1/2" UP from flap and aileron in reflex position. Will call Van's tonight to see what the remedy is.
