How to connect Viking quick release joint of butt to Cuetec shaft with 5/16x18 female joint?

The Ebay store Cue Extensions Plus does not have an adapter. Does anyone else?

I believe a poster here claimed the Viking joint, like the Cuetech, is — at its threaded portion — a 5/15x18 thread. A cue person could thin the Vicking’s unthreaded portion to allow the butt to connect to the Cuetec shaft. The Viking male connection is about an 1/8' longer than the Cuetec male connection (of course, Cuetec’s is all threaded versus Viking’smaybe 3/8" threaded length and about 5/8" unthreaded).
 
I think it's either turn down the Viking pin on the unthreaded part or have the Cuetec shaft bored slightly. I would think modifying the shaft would be the better option but I could be wrong.

That would be the sensible route. Quick work for any competent repair/cue maker.
 
Thanks for the replies.

Comparing the joints of a Viking and a Players butt (I have a Players 5/16x18 butt fitting the Cuetec 5/16x18 Cynergy shaft). My measurements are:
The Players pin length is 14/16" vs Viking’s 15/16 length
The Players pin diameter is 6.0 mm at the unthreaded portion & 7.8 mm at threaded portion
The Viking pin diameter is 7.1 mm at the unthreaded portion & 7.8 mm at threaded portion
Both pins are 5/16x18 thread (as far as I know)

Wouldn't narrowing the diameter of the unthreaded portion of the Viking pin by 1.1 mm allow the Viking butt to attach to the Cuetec shaft? Perhaps no boring out of the Cuetec shaft is necessary since the Viking pin is only 1/16" longer than the Players pin?
Would this be the better way?

Who has connected a Viking quick release butt to a 5/16x18 shaft? How did you do it?

I think you'll find most people have the shaft bored and will be the recommendation of most cuesmiths.

Will a 5/16 x18 shaft fit a Viking Quick Release Cue which is also 5/16 x18?

I can get a very good deal on a Z2 shaft but it is a 5/16 x18 and i own a Viking with the VQR joint but it is also a 5/16 x18. I have no way to check it before i buy will it fit?... Thanks.

The Z2 shaft will fit the Viking QR with one simple modification. The insert in the Z2 shaft needs to be drilled 1" deep with a 17/64" bit. This is not something that you want to do with a hand-held drill motor. Take it to a CM and have it done right.


My calculations are that once the shaft is bored out 17/64", that leaves 3/64" left of the Viking pin to grab the Cuetec shaft.

I had a 314-3 that would fit Viking qr or 5/16×18. Basically a 5/16×18 that was bored out to fit over the pilot. Mine measures 0.264, 17/64 is 0.2656. I doubt the extra one and a half thou will be a problem.
 
A "cue person" can not do magic.. And the proposed solutions are ridiculous. Cuetec has their bastard 3/8-14 and Viking is as pointed out 5/16-18 with a 17/64" minor. So to start with the pins have a 4 TPI thread difference. The minor is obviously also different. If you want to use a Viking shaft on a Cuetec, you can do one of two things:
- Change the pin in the Cuetec cue (about $100)
- Change the threads in the shaft (about $60-70)
Or as a third option you could swap the pin and change the threads in the shaft to something standard like Radial or 5/16-14. A regular 5/16-18 pin will work fine with a Viking shaft.
 
This is not a question about adapting a Cuetec 3/8x14 joint to a Viking 5/16x18 quick release joint. The Cuetec Cynergy shaft here is 5/16x18 and it now fits on a Players 5/16x18 butt (and, hopefully, a Viking 5/16x18 quick release). See Cuetec website for Cynergy shafts it sells with a 5/16x18 joint (along with its bastard brother, the 3/8x14). https://www.cuetec.com/product-category/cynergy-playing-shafts/cynergy-10-5-shafts/

Cuetec offers a 5/16-18 . That's what he is asking about making work. Not a 3/8-14
