Help winding my own inductor?

For winding a choke? Sorry. You ain't worth that much on your best day.

You left out the word between im and possible - probably out of consideration for our tender psyches.

Neither do I. Unless you pay $200 an hour.(;-)

OK. 1.6 mm is 1/16 inch nearly, so that's about AWG14.

I'd much prefer not to

I don't suppose you'd explain how it performs that metallurgical miracle? You can't thread the wire through the centre hole and tighten it to the core without bending it, and bending it makes it work harden.

I expect it does, for thin enough wire.

You need a high perm core. Large wire size makes for low I squared R as well.

Arnold makes some really good cores for this. Also use several smaller gauge wires in a litz configuration for even better I performance at your frequency.

Use a toroid. much easier than a pot core, and better as well. Easy to wind with Litz as well.

Seven 30Ga wires makes for about just over single 24Ga, but performs much better.

Twist them together to form a single conductor.

Count only the turns *inside* the core center.

Humphreys? Right.

Dumbshit. YOU claim to have been winding copper for years.

Copper wire "work hardens". ALL copper wire. For you to not know that is a heck of a tell... Again.

When copper is flexed, it hardens where the flexure takes place. Again, you should know all about this. The flexure has to be very

Be sure to go grab another coffee.

Well, I was quoting Sam Goldwyn, I think. But to quote Tommy Atkins, it becomes one word again 'imfu***ngpossible'. This is an example of 'mtesis', and that is the only English word that starts with 'mt'.

You can't make genuine Litz wire simply by twisting the strands together. The interweaving pattern is a lot more complex.

You are wondeful, even if I can't spell it.

One doesn't gap these types of toroid.

Without a winding mandrel, holding a loose bobbin in one's hand while winding it is no easier than winding a hand held toroid would be.

Imagine that.

You're nuts. Go to any wire maker's site. Litz wire is several strands of finer pitch mag wire, all coated, that are either in twisted, OR non-twisted configurations. You can run ANY number of parallel strands in a choke, and gain a litz advantage at even this low (25kHz) frequency.

It is not woven. That leans toward Litz Ribbon, however. An interesting idea.

You must be thinking of the type of build the winding process on some HF coils has.

Awefully sorry folks, I have just noticed that my c*ck is not being fellated. Normal service will be resumed as soon as is possible.

Hmm, what does the word mtesis mean? I'm not a native English user so it's totally foreign to me and I don't seem to be able to find it in a dictionary. The closest I got to was tmesis :(

Perhaps that is the one John was thinking of. There are a few other "tm" words in English- the plural of tmesis (tmeses), tmetic, and tmema. All have to do with cutting. None would be recognized (even so far as to guess at the meaning) by the average native speaker.

I presume because I've only wound one or two in my lifetime, that I'm not familiar enough with these topics to understand your statement.

I always thought of winding a toroid much like threading a needle several hundred times over. To my mind, you must measure out the length of wire required and thread it through once; pull the entire length of wire through and tight to the toriod; thread again; pull entire length through... etc.

Unless the wire spool from which you're taking this from is *tiny*, or there is a gap of some kind in the core, you've got to "thread the needle".

Is there an easier way to wind a toroid? To my inexperienced hands, it really sounds like a bobbin in a pot core is going to be much easier. What am I missing, here?

Thanks,
