Re: pot shaft diameter????
I've really only encountered 2 sizes of threads on pots. And as I've steered more toward certain brands or even levels of quality, it seems that my experiences have led me more toward stuff with 3/8". In many cases, that means I do have to enlarge the existing pot hole. Just takes a minute.
But generally, most places should show some sort of spec indicating the sizes. If not, perhaps the manufacturer site does. If not, email or call them.

Re: pot shaft diameter????
my issue is less the guitars hole size that can be drilled out. more the inability to put knobs on them[shameless advertisement] https://www.youtube.com/channel/UCh1..._as=subscriber

Re: pot shaft diameter????
There are two types of shaft splines ... fine spline and coarse spline. CTS pots are fine spline, Alphas are coarse spline. Bourns are usually coarse spline. They make pretty much the same style knobs for both types so you should be covered for what style knob that you want. You just have to get knobs with the correct spline type.Last edited by Darg1911; 04-29-2016, 01:34 PM.

Re: pot shaft diameter????
Ok here's what I did to make the Asian metal knobs fit my MIM 3/8 pot shafts
Drill bit
By hand
Slightly larger than existing hole
Test
Nope not enough
Up 1/16
Again by hand
Test
Nope
No more splines
Drill motor
1/16 bigger
Fits
On the first attempts I pushed the back off the pots trying to force it on
Drill out to swedge fitEHD

Re: pot shaft diameter????
I use the big CTS/Dimarzio pots and knobs from EMG (was ordering a pickup/wiring anyways so grabbed some flat-black knobs and rings on the same order). They fit perfect together.
I'm with you OP, it's like they just try to complicate things on purpose sometimes. IIRC the stock knobs on my rg-prestiges also fit the CTS shafts if I need a cosmo/chrome.
Carvin does about everything their own way of course lol. Smaller this, bigger that, different those.Last edited by dave74; 04-29-2016, 05:34 PM.

A reamer is tapered and won't fit into

As for why, it's because there is enough demand for various type of pots that it is profitable to produce them. Different companies and different projects call for different specs, and use different systems of measurement. The why of this is a long and frustrating story.....but you have to learn to work with it, because it's probably not going to change.
You know which is which because you read the specifications of the parts you are using, and/or you figure out that if something from one system doesn't quite fit, then the right part must be from the other system. Knowledge gained through experience will also allow you to see the differences with your eyeballs. You can usually tell very quickly whether a pot is metric or customary simply by looking at it.
Contrary to your statement, all pickups do not adhere to a single standard. They come in annoyingly various sizes, in both commonly used systems of measurement. Off the top of my head, I can think of having read pickup polepiece spacing specs that state (in millimeters) 48 (DiMarzio), 49 (Duncan), 49.2 (Gibson), 50 (various imports and Suhr), 51 (DiMarzio), 52 (various imports), 52.4 (Gibson), 52.6 (Duncan), and 53 (various imports and Suhr), as well as (in inches) 1.915 (DiMarzio), 1.93 (Duncan), 1-15/16 (Gibson), 2.01 (DiMarzio), 2.07 (Duncan), and 2-1/16 (Gibson). Confusing things more, some of those are conversions of each other, and which you read depends on where you're reading it. This is clearly far from a single standard, as you stated was in place.Last edited by ItsaBass; 04-29-2016, 06:52 PM.Originally posted by LesStratYogi Berra was correct.Originally posted by JOLLYI do a few chord things, some crappy lead stuff, and then some rhythm stuff.
