3/8x10 pin ?

Hi Bob
It all depends on what size the hole is.
Some drill 5/16 for the standard 3/8x10, which will accept the modified. The minor on the old school is .281. The modified, I believe is .306 or 7.
Myself and a few other's use a much smaller hole because we use different tooling that allow us to give a tighter fit basef on the old school screw.
Thanks Michael. The reason I'm asking is a few years ago I had a Carmeli cue with the modified pin and either the shafts for it wouldn't screw on to a standard pin or it was the other way around. I just can't remember which way it was.
I've got a very nice Jack Madden shaft that I like and I would like to know if it will work on a modified pin.
A ten minute trip to any quality cue repairman will be able to drill it out to fit.
Hi Bob
Mr. Carmelli uses the modified, I'm not sure what Mr. Madden uses. Like Mr. Hightower said, it's an easy fix. On wood threads, I use a sealer (not c/a)
To protect against humidity change. Longer than 10 minutes but still an easy fix.

Hi Bob,
I’m not a cue maker, just a lowly player. But I’ve been dealing with this a good bit the last year with a few cues & shafts. From my limited experience it seems most standard 3/8-10’s will often not fit on modified pins; they either bind up and/or are not drilled deep enough. But its an easy fix by a competent cue maker, as mentioned. In contrast, 3/8-10 modified shafts do seem to fit on standard 3/8-10 pins no problem.
Cheers
That sounds backwards .
Modified 3/8 10 needs a bigger hole.

I’m no expert, just sharing my experiences across several well known big name cue makers. Last example was a gorgeous custom 2000 Tim Scruggs with 3/8-10 regular pin, my modified shafts all fit it fine, but the TS shafts wouldn’t fit my other butts with modified pins. Another example is Meucci sent me several regular 3/8-10 shafts that were supposed to be modified but wouldn’t fit properly; Meucci eventually admitted they were regular ones, not modified. On those, the regular threads seemed to fit ok, but the holes were too shallow & bottomed out early.
Cheers
