[Unanswered]  Light launcher 2 making grinding noises

Hello. I have gone through about 7 metal fight light launcher 2s in about 3 weeks. The problem with them is that after a few launches, they all start making this grinding noise when launching a heavier bey such as basalt horogium. I make sure to straighten my ripcord but this doesn’t stop it happening. I have heard you can fix this by wrapping tape around the 8 figure thing behind the prongs but I’m not sure if this will work. If this is a solution to it, could you perhaps link me the certain tape needed to fix this?
