Quote: I have a BB small retainer bell that needs to be opened up to accept the med size (4.8 exactly?) OD retainer that I'm going to turn down to fit. What should the clearance between them be? Zero? Or?
it looks like he is doing BOTH , I thought OD meant Outside Diameter , now I'm ASSuMEing it OverDrive , so he is turning down an OD retainer to fit a bell he is going to bore out ...
