Hello everyone - I am building a Carbon Cub - it has the rear spar reinforcement very similar to PA-18 Wips 2000 GW Kit.
It is essentially a piece of 1/8 inch 6061 strip that gets cherry-riveted to the top of rear spar.
I did not clamp the cap strip to the spar tight enough (needed to use more clamps) and I now have a gap about 0.015 inch between the reinforcement and the spar.
The gap is not full length of the cap strip, - it is about 1 ft long.
My question to the member familiar with the subject:
Does it represent a significant problem from structural integrity point of view?
Should I go ahead and rerivet it with oversized cherry rivets? Normal size ones will not work as holes in spar and cap strip will not match after I clamp it to the spar...
I am attaching images illustrating the issue.
