Great job! You know you can go on line and buy specific, oil absorbing rags for setting the balls on to catch the oil, and /or wipe off excess oil still on the balls.
Also, if you check with Mo Pinel, I think he'll tell you that the optimim heat rate to use is 120-130, and no higher. Higher than 130 tends to allow the plasticizers to escape from the ball, WITH the oil.......causing ball death to happen sooner.
