Do you think we can we get the same benefits of spider wound coils but without using Litz wire?

Yes!

Let alone a troll...

Someone that has numerous forum aliases and has even posted as a woman on my forum like you is definitely not the full quid!!!!!

It was amusing to see the deviant members of your forum get all excited and standing up straight. Is it the normal scenario for blokes to get that excited if they think a woman has turned up?

[Doug2]

Oh man!,

I want my special answer from Robby_H "guru". Maybe he can raise his competence this time.
WM6, sorry but you are wrong.

Yum Yum....

You really aren't the full quid Moodz. Perhaps you should deflate yourself, and then see what you can do to deflate Mr Pardonmee also.

Doug, cheaper an easier are not only benefit with bundle coils. At the same wire length used it mean more inductance. More inductance mean stronger magnetic field. Stronger magnetic field mean more depth. Practically proven (I left theory for others).

Weakness: more coil parasitic C and this way harder to get short time constant (important in first line for tiny nuggets). But in question of depth (same diameter) bundle is better than spider.

This, if we are talking about classical PI technology. Maybe moodz new technological approach can overcome this physical facts - I don't know. I even do not understand his new technological solution in whole, but as most of us, I wish to see finally something (like prototype in field) working.

But if the inductance of a spider and bundle wound coil is the same then does the bundle wound coil have a higher field strength (same diam coils)?In my opinion you would need a big increase in field strength(due to higher inductance) to see a measurable increase in depth.Higher inductance will also change the coils Tc and in the case of a well known detector brand may result in a lower peak coil current at switch off !ie a lower field strength!
My experience with a spider wound litz mono was that its sensitivity (and depth capability) was significantly better than ANY equivalent diameter commercial mono!

Hey wm6 .... I am just making coils to do detector tests .... I am not claiming anything ....

Hey wm6 .... I am just making coils to do detector tests .... I am not claiming anything ....the only reason for making a basket weave was to make a flat coil that was easy to pot in resin. Can't afford to buy 5 coils at $500 each. :-). Paranoid99 thinks everything is some sort of invention.

My respect and best wishes to your work, moodz.

I wish to see more technical and less personal discussion here. More technical Pro et Contra and less personal Pro et Contra.

PJ other than bundle wound coils being cheaper and easier to manufacture, what do you think are the technical benefits of bundle wound mono coils compared to spider or basket weave wound mono coils?

Let Doug talk Moodz into building a bunch of these coils. Maybe then Moodz will figure out the truth about Doug and run as far away as he can.

[Doug2]

Actually if you knew your subject Peter ( AKA P99 ) .... there has been alot of research into basket weave coils and litz wire. The main reason you dont see them in commercial coils is manufacturing difficulty coupled with mechanical stability and bulk of the windings. However the use of basket weave in a resin matrix overcomes these difficulties and the basket weave actually reinforces the resin addition to the other benefits. The resin also prevents the windings moving relative to each other which causes instability when the coil is knocked.

Coils are already far too expensive!Spider wound or basket weave coils would be vastly more expensive for the reasons you describe.

Hey UFox,

....QLUD's? (Quantum Lead Ultimate Detector(c)(r)(tm) )
^sif

^sif, I do believe that should be QLUDD's (Quantum Luddite Ultra Dud Detector (c)(r)(tm))

[Aziz]

Hey UFox,

you mean I should produce and sell QLUD's? (Quantum Lead Ultimate Detector(c)(r)(tm) )
Oh! oh!, no good for Greedlab's profit.
