Katana shaft does not fit. Solved!

Hi i just got my 3/8x10 katana shaft, but it does not fit my Leon Sly or Jim Baxter cue, both obviously with a 3/8x10 pin. Looking at a McDermott 3/8x10 pin, the pins in my cue looks a bit different, they are not rounded like the McDermott pin and they look a bit longer?
My pin looks like this:

3.8-10%20FB%20pins%20small-342x342.jpg


My thinking is to get a regular 3/8x10 bolt and force it in with a wrench and thus loosening up the threads. Will this F up the threads? If so what else can i do?

If the shaft is in fact a 3/8-10, the only real difference in the thread is the minor diameter. If you force it you will probably ruin something. If you take this to a compitent cue repair person, they can bore out the minor diameter in the thread to .308 (the minor diameter of the "F" pin) and it should work. This is not hard to do.
 
I had a similar issue with a set of custom 3/8x10 joint protectors I got for me son's cue, it was very tight, bordering on being impossible to put on, going on the screw but they were fine on the shafts. Mike Webb did his thing on it and they fit fine, so there is some variation with how the threads are in those pins. I'm sure there is a cuemakers forum section discussion on this topic in there if you do a search for that pin size there.
 
Pretty sure it's 3/8×10 by looking at the joint protector that came with the shaft.
Katana does not make 3/8x11. And radial would have a steeper turn in the windings wouldn't it?

So i managed with leather gloves and elbow grease to make the shaft fit my cue.
Having said that i think the whole industry should agree on standards.
That 3/8x10 is not 3/8x10 is insane! and that some cue makers have their own proprietary pins or use something like 3/8x11 wich the aftermarket shafts don`t have threads for if messed up.
Being a European i find the system insane, compared to a logical metric system :)

The worst thing you can do if force or have real tight threads.

If its to tight chances are it will crack the joint part of the shaft.

I did it gradually to minimize the risk of cracking at the joint and i used tons of lube, so the friction was minimal. It took three days of carefully, screwing/unscrewing until i got the shaft all the way down..
Sure It`s not ideal, but there was no local cue repair service that could help me and sending my shaft back to the states ($50 each way + work) was something i rather not wanted to do.
For future shafts i have now ordered my own 3/8x10 tap from AtlasBilliards.com :)

I agree. The 3/8 pin debacle of diff sizes in crazy. And yep, the US should have went to the Metric system 40 years ago when we had our chance ( and we were suppose to do)

I bet 90% of folks, ( non trades dudes) can count the "ticks" on a standard ruler.
1/16, 1/8, 3/16, 1/4, 5/16, 3/8, etc., etc

If it was Metric, it's automatic, and a 3 year old could do it :)
 
Yep, there is the standard 3/8-10 Atlas style thread, modified 3/8-10 (may even be a couple of different types of these 'modified' ones with different minor measurements), ACME 3/8-10, no doubt more even....lol. Very much a pain for some folks. :mad:

I've found hardware for pool tables to be the same.. I'll go to hardware store to get a replacment bolt and my tap will cut deeper threads than what the factory put on them but my tap won't cut any shallow meat off a table original bolt..I've found a lot of this when cleaning up/chasing out threads of nuts and bolts...

I've seen a cue or two that is made to have a tightly fitted wood shaft to the pin, I recall every onley cue fresh from the shop being really hard to screw together/apart and apparently designed that way....perhaps that why huebler used a plastic insert? They thread fairly firm too....

Sorry if off topic.
