Thanks Guys!

I only need to shorten them a about 1/8th of an inch. They are the ball/cup style. I could order new ones but I probably have 30 (swap meet buy) that are too long. I have some extra time before my next race so I figured I would at least see how difficult it would be.

I don't really have the skills or access to use a lathe so I'll have to keep thinking about the best way to cut them accurately and safely.
