[Jukebox-list] AMI F-120 Selector Button Question

[peshkin at comcast.net]

I just finished the final touches on restoring my AMI F-120.  As you may know from my previous posts I am a complete novice, but have managed to slowly complete the task.

I have one selector button that pops out off the flat shaft (that has a hole in it).  Can someone tell me how the buton was designed to stay on the shaft?  What other than simple pressure hols the button onto the shaft?  What is the fix?  Thanks.  Have a nice remander of the Holiday weekend.
