Guys,
Tonight I decided to 'store' the bottom skins by clecoing them to the wings at the end of the night. What I got worries me somewhat.
As was to be expected, I had to warp the ribs somewhat to lineup the holes and insert Clecos every 4 or 5 locations but what I didn't expect was the hole offset at the spar!
After aligning the ribs and attaching to the rear spar I had a significant offset for the #40 holes in the main spar.
The darker shadow in the holes above are the edges of the countersink in the spar.
The flash and backlight show this as well
The flash picture is not making it look worse! The offset is bad enough where even with the cleco a few inches away there is an offset on the spar.
This offset appears constant and not some sort of warp inboard to outboard. Looking at the inboard skins that were already assembled, the gap between skins (.01~.02) is also much less that what I can do with the outboard skins(.04~.06).
I really can't think of a good way to approach this. The spars are drilled and the main is also countersunk. How could I drill and dimple a skin this far off?
