Hey fellows I'm trying to build a set of ball type counters to attach to the side of my homemade light. I am wanting to have 11 balls on each of two rows and sliding on 3/8 inch wooden dowels, so I'm worried that styrofoam balls will wearout inside and out due to sliding and pushing them with a cue. Have any of you made a similar counter and do any of you know of a better 1 to 2 inch ball that I can drill for this purpose. I like the ones at the US open but want to use smaller balls. Thanks --Leonard
