K7 spar cap bonding test

K7 wooden glider spar cap bonding test. There is no easy way to non destructively test the spar cap bonding of wooden gliders. So every time we decommission an old glider, we cut the spar cap out of and test the spar cap bonding.

Nice test. Looks like it is still pretty fine. Gives me a better sleep :)

One of the joints seemed stronger than the other. Was the spar deemed airworthy before this test? In retrospect was the spar airworthy?
