Recently picked up a small batch of bearing balls from a friend at his machine shop. They work fine in my Pachinko machine. Does anyone know the true measurement of one of the Pachinko Parlor balls. What would be the correct millimeter? Wonder how much they would cost to purchase. The only difference is that they would not be engraved. Would anyone else be interested in looking into these or are we all purists requiring engraved balls?
