Bionic Balls Posted January 13, 2007 Report Share Posted January 13, 2007 sounds like a job for a file....don't think there's alot you can do without a new ring or BB...longer BB next time maybe? Quote Link to comment Share on other sites More sharing options...

Onza Kieron Posted January 13, 2007 Report Share Posted January 13, 2007 30 seconds mor elike and you have solved the rubbing but not the fact you have no cog left... but yeah, grind it responsibly. Quote Link to comment Share on other sites More sharing options...
