I'm pretty sure i'm going from a 10 to an 8 (or an 8 to a 6), i honestly don't remember what the exact numbers are: it's been over a year since I even thought about it. Anyways, I've got the taper all the way in. It goes through without a problem. But I can't get the jewelry to follow it. I push the taper with my new barbell and at some point the jewelry gets stuck, but the taper keeps going. Any suggestions? Also, yes, the taper is the right size. I promise i'm not a complete moron. EDIT: So I got it in, after a lot of trying. From what I can tell there's something partially blocking the path. As soon as I worked the jewelry at an angle to push around that, i felt a slight sting, the resistance "gave," and my barbell went through the rest of the way. Any thoughts on what that could be?
