Spent an hour grinding down some AN5 bolts to make them easy to push through the wing spar during installation. These bolts will be place holders while the wing spar is inserted into the main spar to help with alignment. Once the spar is aligned, these bolts will be replaced by the final bolts which will likely take some serious tapping to get into place as they fit quite tightly.
"Bulletized" bolts to slide into the wing spar during installation.
