Proprietary joints...

I have some customers which are looking at McDermott cues but want me to get them OB-1 shafts for these. I have done the exercise of getting the custom work done by McDermott, but I have now lost a little track of what is what...

One customers want's to buy a cue with a 3/8x16 joint and then he has also found cues within the same brand which mentions "Quick release"...

I know from earlier that the McD "quick release" is for sure a oddball but is the 3/8x16="Quick release" ?

Is there any one who knows where to buy the stock inserts so we can retro fit these to which ever shaft without having to make them our self? The process of shipping the OB shaft to McD takes a lot of time and has not always been 100%.

Any one ?

Hi Kent,
Yes, the McD. QR (quick release) is a 3/8x16 thread.
The pin is similar in design to a Uni-Loc but instead of having just the one thread (Uni), the McD. QR has about 5 or so.

With regards to the inserts, your choice of the word 'proprietary' is indeed fitting. The pin & the insert are both McD. designs and parts are unavailable anywhere except through McD. Don't hold your breath.
There is no reason, a man of your talents couldn't make either yourself.
1/2" brass bar stock turned to .460 od. Cut to 1.437 length. Drill/tap=insert. Cut grooves on od to hold epoxy. I make pins from 3/8" stainless bolts.
If you could buy parts from McD., the price would scare you. The insert is $12.USD. You can't buy the pin separately from the joint collar. It's all one piece.
I've told you, anytime I can help, just ask.
 
Hi KJ

Thanks for the feedback, it is highly appreciated :)

I was afraid that these where something we need to make our self so I guess I have to start looking for some materials to have in backup in case these turns out to be "hot items". I guess 12 bucks is something I could survive once in a while, but they would most likely be $15 + S&H when they arrive in my end :(
And then I have to get a decent lathe I could make these on and not the 700mm lathe I have available now..

I'll let my customer know that the McD "Quick Release" is the same as the 3/8x16 and make him aware about the drawbacks. Actually one of my customers which I manage to get a custom fitted OB-1 with McD "QR" delivered to, says he is really not happy with the setup, where the shaft some times comes loose during play. I'm not sure if this is related to just this customer, but it would for sure be a "no-go" if I was buying a cue.

Have to hit horizontal now.

Thanks
Kent

Make sure you specify, they also made a 3/8X10 quick release.

I think the 3/8x10 is the stock joint which many use.This is not a "quick release" as far as I know, since it needs to be "twisted" much more than the original QR. Anyway,thank you for the tip.

If the thread you need inserts for is 3/8 16 you can buy a 1/2 inch long brass nut in the USA and machine the outside of the nut round and make glue grooves to any size thread you have a tap for. If you need brass nuts in 3/8 16 I'll try to ship you some.--Leonard

Thank you so much for the tip and offer for help Leonard. The customer is bombarding me with emails about whic cue to buy, so he is for sure not decided on which one to go for.So I'm not sure what he decides so I guess there is no immediate need but if I may, it would be great if I can take you up on the offer when I have checked locally.
Thanks a bunch.

Jupp jupp. I have this joint on my 20 year McD and all the later cues from them, like it a lot:) It's stock in the OB family of shafts so this is no problem.

I have both quick release systems from McDermott, Joints and inserts. Just trying to help, but if you think it didn't exist, that's okay too.

Mike is correct. McDermott has used a 3/8X10 pin since their inception but they also had a 3/8X10 quick release pin and insert for awhile.

I don't know that the 3/8x10 was ever a quick release.
McD. did make a brass insert for the 10 thd. pin but it was a full length insert. No quick about it. I have one in the shop.

Ho ho ho, Mike, my apology in this respect. I did not know that they even made a 3/8x10 QR as well.... I thought these was the stock old wood to wood joint used from the day.

So to summarize:

The customer could run in to 3/8x10 QR, 3/8x10 Wood2wood and 3/8x16 QR then.

Well, I guess I just have to wait and see what he gets then.

Thanks a bunch guys.
