I'm finishing the mains on a Aeropro Drive GT. As I pull tension on the 8th main, the grommet gets tugged to the side and disappears into the frame and the outside of the grommet base pops out. I'm afraid if I tied down and then release it will be stuck and would be hard to manipulate with an awl. Any suggestions? I didn't have any problems on the other side for the 8th string.
