Finally started on the bottom skins today. I found the problem with the inboard skins being too short. I was kind of expecting this based on reading a number of build sites.
Sketch 9 shows the overall length of the skin to be 48”. When I add up all the other dimensions on this drawing, the over length should be 48 1/8 ”. When I do the same calculation based on the rib stations, I get 48 1/8”.
Finally when putting the skin up against the skeleton, it looks to be 1/8” too short.
The outer skins is correct at 48” but is supplied at 49”. I assume this is to allow an overlap joint as done on the QB wings?
Any one got a rivet pattern for the overlap joint? Ie two rows of rivets at what pitch
I may decide to buy some new material and make a new inboard skin. It may be possible to get the 1/4 edge distance but there almost no margin for errors.
