Drilled, deburred and match drilled the -3 half of the left wingtip bottom hinge using the -4 half as a guide for the -3 hinge location. Countersunk the holes in the wingtip for AN426-3 rivets and clecoed hinge in place for a test fit. Trimmed the wingtip to remove the “spacer” section and installed on the wing. Unfortunately it has the same play/movement as the right wingtip at the trailing edge. Not sure how I'm going to correct this, but will work on it some more once I get the wings out of the cradles. Trimmed the bottom of the left wingtip rib where it interferes with the hinge and match drilled it to the wingtip with the blind hole tool aligning it with the rivet line.
