Maybe even borrow one for that local racer.
Interesting.
I'll probably just give them a quick polish on a dremel then.
To the extreme I wonder how well taking them to a machine shop to remove a thousandth around might help.
That's way above what I'm willing to put into an area I don't see a problem, I get way more binding at the pins. Just assuming that might be ideal. Though what the heck is a ball cup reamer? Just opens the cup rather than working on the ball?
