I got this stringer used about a year ago from a friend. It was in perfect condition when I got it. No issues at all and I had no problem stringing 50+ racquets. Yesterday I finished one of my rebels with no issues what-so-ever but halfway through the second racquet's mains I realized something was horribly wrong. I'm not really sure of the technical name, but the top of the stringer is not staying level during tensioning. So pretty much instead of just turning around the top of the stringer now moves up and down for some reason. It is really hard to explain, but if someone else has had the issue I'm sure they know what I'm talking about. I'll try and get a video or something at some point, but in the mean time if anyone has had the problem and knows what to do or just has any suggestions I really need them.
