Question about threaded ferrule

[shankster8]

I just read a thread in the Cue Machinery and Supplies forum entitled "What tip for this cue...?" A responder to that thread noted that the shaft needed both a ferrule and a tip. The pictures show a threaded tenon at the shaft's end. I don't understand why the shaft was machined this way. I imagine the tenon is threaded to accomodate a threaded ferrule, but I don't understand why the joint-end of the tenon is cut deeper than the ferrule threads (minor diameter?). Seems like that would create a void beneath that portion of the ferrule. I am probably missing something obvious, but please explain this.

That is a good question, I think that the design sucks personally but the name Excalibur says it all. The cue is an import Chinese one piece house cue imported by Imperial Billiards.

If I was going to put a ferrule on that cue, I would turn the tenon down and re-thread it and take care of that problem.
