My newest pair of juliets is great with the exception of a floppy left earstem. Normally, the screw just needs a twist and it takes care of the problem. In this case, the screw is slightly stripped and I don't have a replacement yet. I got it as tight as I could while still being able to remove it when I get a replacement. My questions is this: Has anyone ever used pliers or vice grips to tighten the end of the frame the stem fits into? I'm not talking about using a lot of force, just enough to crimp the ends closer together. I'd use a rag to prevent tool marks on the frame but you get the idea. Anyone tried it?
