Seems to be plenty of bright folks on the forums here and I'm hoping someone can point me in the right direction.
I have a couple crusty tricone bits, one has a cone with some slop, another has a cone that won't turn 360 degrees. How would one go about pulling the cones to gain access to the bearings? I know there is a retaining pin but I'm not sure what the normal approach to remove it is.
