Predator threading for extension

A number of older Predator cues come standard with a press in rubber bumper which will not accept the Predator extension.

But it is quite a simple fix, threading for the Predator screw bumper which is threaded on the inside for the extension.

I cut the threads in my CNC lathe with a thread mill.
