Predator SPJ joint diameter

[Elvis]

Hey Sid or Deb, I am going to get a Predator shaft with 5/16X14 thread. Can you tell me (using a micrometer) what the diameter of the SPJ is? Are all Predators pretty much the same diameter? May get the entire cue vs. just the shaft if everything is interchangable with what I have..thanks

I just measured the joint of the SPJ and it measured at .838, which is pretty much the same as the rest of them. thanks

I don't have access to a micrometer to measure my butt collar. Can someone convert this(.838) to mm for me so that I can tell if I'll need to send my butt in to have it fitted? As long as it's within a mm or so of my butt I'll just order one off the rack.

Thanks!

I did the math and came up with the answer 21.2 mm.
If you need to try it out for yourself remember that 2.54cm=1in.
I hope that this helps.

Exactly what I needed....thanks a bunch!
