What brand is your guitar? You can just push them back in, but it'll happen again. Glue?
Seems like an issue with a cheap and low quality construction.
There should be a nut/washer to hold it in place
Hi all, recently noticed 5 of the 6 tuner posts coming off the headstock of varying degree. Is this a cause for concern? Anyway to fix this since there are no nut on top to tighten in this case? Thanks.
From the image, it looks like the tuner rings (washers) are too loose for the existing holes.
The posts are attached to the gear and should not come off.
What you can do is to remove all the tuners and refit the rings securely over the holes.
This can be done either by tiny drops of glue or using fine tapes to increase the diameter of the ring shaft.
Hope that helps....
My apologies.............the correct term for those rings/washers should be "bushings"
