I have a buddy that has an Action cue that is wanting some j/p's made for it, PLUS I'd like to have a maintenance pin for it so I can work on it. It is a quick release of some kind but I have no idea what size or what thread it is. Can anyone help me out on the size, possibly where to get a tap so I can make some j/p's for it and possibly where to obtain a maintenance pin for it ??? It breaks down to a jump/break cue, but the regular joint pin AND the jump/break pin are exactly the same. A pic is attached for reference. Thanks in advance for any help.
