[krv3000]

well their is several ways to do this if you don't have a Colet chuck put sum bar stock in your lathe say its 20mm long drill threw say 2.5 mm just for daftness say the ball is 10mm OD so drill the end of the bar 10mm by 5mm deep the ball shud be a snug fit if not drill out 10.1 or till you get the ball to fit nice then super glue the ball in place then drill and tap the ball then remove from the chuck and warm it up to remove the ball the hole all the way thew is to help remove the ball or in the mill mack up a v block to hold it in the vice on the mill a another way is to cut threw a nut that the ball fits in to put sum tape on one side of the nut to stop the ball failing threw then put the nut in to the vice on the mill with a parallel under neath and nip the vice up just a nufe to hold the ball and drill that way hope that helps
