He mentioned about holding the ball to grind it by what ever means you come up with.. So I thought that is someone was wanting to make one of those tools it would help them to see an easy and safe way to hold the bearing ball.
I started out with a hydraulic compression fitting and nut. At first I was just going to clamp that in a pair of locking pliers but decided why not make it into a real tool SO I machined off part of the fitting and machined a handle then welded them together But while doing this after I was nearly finished I said to my self this wold have been a whole lot simpler to have counterbored the handle then threaded it to fit the nut DUH!
I am horrible at knurling but put just a slight knurl on the handle for better grip
