Hi All, I have been CB6KS for over a year now. I use the largest ring but have had regular ball pop out problems. I have tried different spacer options all the time. When I try to move down a ringsize everthing fits real snug and I am very happy. The only problem with the smaller ring is my skin gets nipped after it folds over a fraction. Now the perfect solution would be for me to try and enlarge the ring size a fraction. I have tried all sorts of mini grinder heads and drill bits on their sides but the stuff the rings are made of is so tough I cannot get that fraction bigger. Has anyone made the ring size a fraction bigger and with what tools? I have made the largest ringsize a bit smaller with tape etc but that is not good long term hygine so I want to move down a ring size - a fraction. Any practical help out there without a degree in nuclear physics? dubsub happy lashed and locked.
