Looking for thoughts on aligning the bellcrank pair at the wing joint so that the pivots are collinear. Newsletter 118 has a strategy. Any other ideas?

I didn't drill the pivot bracket holes to final size until the wings were mounted together with the pins. They were skinned and riveted. The brackets were also riveted. I took a long drill and came up through the bottom to ream out the final holes. If you look at my plane today, you will find a hole at the joint on the bottom of the wing that was where I accessed the fittings. More fun is making the final adjustment to the rocker. Lots of wing on -- wing off, repeat. Then, after the first flight, you get to do it again.

Bob beat me to it! Leave the #40 pilot holes in the bellcranks, assemble the wings, align the bellcranks, use a long #30 drill up through the bottom skin up through the bellcranks.

I got my bell crank parts from CSA . The hole in the hub was already drilled out for the bushing . Assembled the bell cranks and with the un skinned outer wing clecoed together with the ribs/spars and joined the outer and inner wings (inner wing skinned) with the two pins and the two bell cranks "mated." I ran an AN bolt thru the two cranks/bushings and then marked the rivet hole locations for the bell crank brackets . The fit is so close I do not need the "adjusting AN bolt " on the inner bell crank . Probably 1/32nd inch of play or less ? :o OH MY !
