Drilled the hinge to the wing tip. First I match drilled the -4 hinge. I then measured from the match drilled holes to the center of the -3 hinge and transcribed that line to the wing tip. I copied the positions from the first row of holes to the transcribed line. Last stage was to match drill the -4 hinge.
Afterwards I did some small trimming of the hinge and started to cut off the flange of the wing tip. The cut off will be used as a spacer when the -4 hinge is riveted to the wing skin.
I clecoed it all together, lubed the hinge ping and mounted the wing tip. It went surprisingly well, strangely enough the top hinge with more curve to it went easiest.
