After opening up the spar box a little I could walk the CS spar in without too much trouble. I needed some give so that adjustments could be made. See pic 1

After all the work I found the incidence off between the wings by about .4 of a degree. I thought about it for longer than most people and realised that I needed to take out that extra washer I’d put in to correct the incidence. I’d built things better than I thought, I was then able to get exactly the same incidence on both wings to 0.00 without any washers.

The whole setup is quite a challenge. Pic 3 shows me checking sweep. Its really from the next day but I had room in this log. I’ve used aluminium angle iron clamped together and just done a check from LE wingtip to the F28 center-line. The wings were .4″ different which over that distance is almost noise. Funny in that I thought the sweep was out 2″ when I first checked on the floor, then it was only 1″ after things were bolted together and now I’m 0.4″. All good.

I also checked the wings length left and right and found they were 0.1″ different. Again I thought it was a touch more but it seems things are working out.
