Thanks for your opinions. I'm not asking if I should or shouldn't change the pin. The reason for wanting to change is this is a very slim butt cue (which I like) and I have 8 older 314 shafts that I use and would like to mate this cue to them.
So what's the best way to change to a uni-loc
The change should be very simple for an experianced person. I don't remember the 5/16x14 joint screws having a shoulder on them.
1- Remove the joint screw.
2-Check the dept of the hole
3-Bore for the countersink and shoulder on the uni loc
4- Install the screw with the proper expoxy. No quick drying expoxy for this. There's mixed emotions on epoxies on this forum. I know what works and what doesn't.
5- After the uni loc dries in place, face the joint and your done.
Best move, find someone close to you to do the work.
I'm not taking any work but I Hope this helps.
Sorry, got ahead of myself.
Most 5/16 joint screws I've seen are 3" long. They usually go in 2-1/8 to 2-1/4 deep.
Uni loc goes in 2-5/16.
Very important that the uni loc screw gets wet sanded with 2500 and 3000, then polished before installation. I use uni loc in half the cues I build. It's a great system when done properly.
