Cross threading a shaft

Hi cuemakers!

I have a question for you all:

Is it possible to cross thread a 3/8x10 shaft into a 5/16x18 butt?

Thanks in advance for all of the responses :)
 
Would be a neat trick if you could. Sorry the 5/16 x 18 outside thread diameter is .312 and the 3/8 x 10 inside diameter is .312 so the 5/16 x 18 should just slip into the 3/8 x 10 without or barely touching the threads.

Thank you Sir, I tried it too and it's basically impossible.

Just can't let it go can you? Going to drag your cuemaker buddy through the dirt by trying to defend him.

He can let his own product, and his own behavior/actions talk, but you have to keep poking at people.

You don't like my posts? DON'T READ THEM !

And when was the last time the cubs won anything? :D :rolleyes:

With friends like Remy, who need enemies?

Keep up the good work, I'm sure Jeff appreciates your efforts to keep his misdeeds in the spotlight.

My question here was for cuemakers Sir. Are you one of them?

If not why do you care how many friends I have? Well I have all the friends I WANT and Jeff is one of them. Is that ok with you?

Cubs suck, I'm ok with that. I'm sure your cuemaker friend just loves you keeping the negative up front and center. Carry on.

Sure.

But I must say, if you really consider Jeff a friend, you ought to sit down and STFU.

Makes no difference to me either way; not my problem. But I do feel real sympathy for Jeff as his "friends" are keeping all threads about him bumped to the top.

But by all means, carry on.

I have not read whatever threads the other guys are talking about so I am clueless about your motives here and I am going to give you a serious answer.

Yes it is possible to cross thread a 5/16-18 into a 3/8-10 shaft. Some people use a .302" drill for the 3/8-10 and a 5/16-18 would bite into the threads doing some damage. Even if the shaft was drilled with a .312" drill you could still start the 5/16-18 in at an angle and cross thread it and damage the threads.

I use a 3/8 x 10 pin, flat minor and use a .307 hole to tap with, and once accidently tried to put a shaft onto a repair cue that had the similar type of ring work and the butt was a 5/16 x 18 pin and it did damage the shaft threads enough that I had to bore and plug the shaft and re-tap. Now I keep my repairs and cues I'm building in separate racks.

Don't know what led to the drama in this thread. Don't care, either...

OP, 'cross threading' ain't happenin'.

That said, if you have a 3/8x10 shaft that you want to put on a 5/16x18 pin, a cue maker can put an insert in the shaft to accommodate a 5/16x18 pin. And then it's a 5/16x18 shaft (and not interchangeable).

If this answers the question, glad I could help.

Otherwise, you guys can carry on with the drama...

These pics might explain some things by visually seeing the pins. Maybe not.

I'm not sure if you're being sarcastic to me, or the other's.... either way, All I know is what I have done by accident in my shop. I also did not screw it all the way down, I realized about 1/3rd of the way that I had screwed-up. The threads were not destroyed, but chewed enough that it needed to be redone. That was when I did wood threads in the shaft, now I do either phenolic insert or another material that is harder to damage.

I guess I was being sarcastic to those who still said you cannot cross thread a 5/16-18 butt pin into a 3/8-10 shaft. Even after your experience has already proven it to be possible and likely to happen. You can also cross thread a 3/8-10 pin into a 3/8-10 hole also. Just about anything not started straight can do damage.
 
I want to Thank all of the cuemakers for the responses.

I really appreciate it.

Have a great weekend :)
