You didn't mention either loctite or any kind of lock washer. I've got both in my tool kit, but that doesn't make me a fastener expert.
The nice thing about spring washers and star washers is that you can see th at they have been installed. Thread locking compound is mostly methacrylate
-based and only hardens in an oxygen-free environment with bare metal surfa ces around, so it's less obvious to the naked eye.

No. I sugested that a gap might help. Pretty obvious that one cannot perform such a task on an already assembled unit.
Fuck off and die, dumbfuck SloTard.

Yes, Billy They are not "machines". Here in the science world we refer to such things as "instruments". A profilometer is just the instrument for this. I do not expect you to know.

They are available off the shelf, so it is pretty easy to say that they are for the job.
You are petty, f*****ad. Go away Billy SloTard. Your immaturity is glaring.
The devices are there and designers use them. So much for you and your inane, insulting remarks.
Actually, that does depend on the unit, and the way it has been assembled.
My suggestion would have involved redesigning the whole circuit.

No. You are pretty much clueless about everything.
If you are so blatantly stupid that you cannot imagine a design where a pot core gets used and not the clamps, then you are pretty lame in the conceptualization realm.
But that goes without saying, since your every response is a insult and debates nothing on the issues.
Still trying to figure out what reluctance is? FOAD, Billy.
Bill Sloman wrote in news: snipped-for-privacy@googlegroups.com:
Again with the retarded attempts at insulting.
FOAD, Billy.
You posting a link is not you having a grasp. And you disclaiming it as well is certainly a flag.
You ain't real bright, Billy boy.
I've published in the Journal of Scientific Instruments. Those instruments are still machines, even if the marketing department want to use a more pretentious name.
And a profilometer is one of several approaches.

You responding with a listing of what was missing from my post about using a bolt is pretty petty, child.
I do not need to list all of the elements. You harping on that is a huge tell.
Billy has no clue about transformers.
And no. You are not an expert on ANYTHING, no matter how many hobby tools you have collected over the years of your inane, useless life.

Filtering Billy would be me snipping some of the irrelevance in the group. Bye, childish punk.

Laser interferometry is the most accurate.
But you having any clue, Billy. I doubt that. You cannot even figure out a 555 timer.
You denied that introducing a gap between cores halves changed the inductance of the part. That really was clueless.
-- Bill Sloman, Sydney
There are other parts that can do the job even more precisely.
There are other devices, and you don't seem to know about them.
-- Bill Sloman, Sydney
It does rather depend on having mirror finish.
The electron beam microfabrictor I worked in the mid-1980s used an HP laser interferometer, and at one point I could reel off the wavelenght to ten digits.
Sure I could. Well enough to work out that it wasn't good enough for the jobs I needed done. As usual, you missed the point.
-- Bill Sloman, Sydney
You guys can squabble forever. Well it seems to amuse you and keep you out of serious threads.
We sometimes attach a pot core pair to a board with a nut and bolt. That's handy for coax-based transmission-line transformers.
I wonder if there is a case where the PCB itself becomes the pot core gap.

No, I did not deny anything, you presumtuous twit.
I said that as a transformer, it did not matter, as in the transformer takes a negligible performance hit as a voltage converter, which is what it is. Used as an inductor, it would matter as it changes value slightly. But I never said anything about gapping an inductor core, you retarded putz.

You are clueless if you do not know what a pot core with polished mating faces is used for.
That decidedly makes you a know nothing, and particularly as to what part is good for what job.

You are an idiot. Laser interferometric profilometry has been around for a couple decades as far as an easily available end user instrument.
The surfaces they profile do not require "a mirror finish".
They work on micro-sized parts no mirror finishes there, as well as the macro, which we all know of as lidar, and that profiles and maps entire areas of Earth's surface. No mirror finishes there.
You rather depend on a Donald J. Trump style of cluelessness.
Bill Sloman wrote in news: snipped-for-privacy@googlegroups.com:
So, you are so narrow minded as to be clueless about the myriad of uses that the world has come up with for interferometric amalysis and are only familiar with the state the art had when you were actually a little less senile than you are now.

It would have to be a VERY thin PCB, so no, not very likely at all. Too leaky to be of use as far as transformers go. Still able to use as an inductore though. Not recommended.
Now, a PCB area could be made with a cavity in both side and a thin PCB layer in the canter. Since multi-layer PCB boards use very thin layers before they get laminated together.
But still very unlikely.
