Hey everyone, the mechanic on my e string is kind of loose. The handle isn't hold properly in place anymore and also won't grip the gear properly but I can turn it quite normally with a little play. It didn't rattle or anything before. And I only noticed it after I started changing strings and now I'm really not confident in getting tension back on it.

Is there anything I can/should do? Are there screws I can fasten for this or is it an "expensive" problem an I have to go to the Luthier?

I'm going away to a concert weekend tomorrow and I don't know if I have the time to drive to my Luthier

Thank you all in advance!
