Trifilar Coil Jig

[bomentyr]

hey its a mistake just 1+ not 1+1 because its strats count 2

[storyb23]

this is pretty fucking awesome

[KaleemNiz]

calculator can not calculating the actucal number of trun because the diameter of ur dril which is pressing the button of calculater is less then the cap of coil which ur using for wind....

[codygillespie]

@KaleemNiz

Both diameters are fixed on the same shaft. 360 degrees of rotation on both diameters per turn equals one turn per rotation on both. Think about it ; )

[sutthiLhong]

Try using smaller hole less then 1cm on the feeding side & increasing distance between winding spool & the feeding spool further apart (50cm++) once the first layer is done nicely, by controlling the right speed the following layers will be auto arrange

[sutthiLhong]

Nice! When i put together mine, it took me sometime to figure out what to use for counting,after squishing 1calculator & 1keyboard i ended up using a "thumb pressing" counter. together with a few bigger hole washers (place them off-center) as trigger. it can count up to pretty high RPM without miscount, and can withstand harder beating from the drill's torque.

[kurdishmob]

kholy shitz. ur da man.

[djahriman]

Very well done sir :)

[GHOSTTOYS]

ingenius hahaha 

[77GSlinger]

Fucking brilliant! Thank you!

Explain why twisting two wires together helps your circuit, or any coil, for that matter, please.

[codygillespie]

@JRBeaman

Well as far as function its not something that would always be required. Mainly it helps keep distributed winding capacitance even. Also for practical reasons it helps keep the coil compact and tidy.

[JRBeaman]

@codygillespie I would expect that twisted windings would actually take up more space than conformal windings. The purpose of winding layers in bifilar or trifilar method is to reduce self inductance characteristics and actually increases the capacitance to help compensate for back-emf characteristics which could damage semiconductors. The twisting has me baffeld as I see no advantage & could cause potential concentrated mechanical stress points for potential short circuiting in the windings.

[codygillespie]

@JRBeaman

I would agree with that if you are running the filars in series. But when using each filar individually I would say it can help ensure each wire has identical L and C characteristics. I would also agree that you could make a coil smaller without the twisting, but in practice ive found I usually end up with a rats nest when dealing with untwisted multiple wires, but sure it could be done. Ive never had any problem with short circuiting. I would say do what ever works for you.

[mdbreedi]

Just finished with my coil jig winder and I sure appreciate all the info you had on your video to help me build one also. Thanks again and keep up the good work.

[binarybox2003]

Well explained.

I like the counter and the overall control gets the job done and the rewinding to get a neat job is a good idea.

Tnx 4 posting.

[Grieverjoao]

When i saw your counting system i laughed so hard OMG. It´s a very cleaver method and its easy to use. NICE.... 5 stars!!!

[josephaarongermany]

lol I wind transformer coils for a living. The biggest coil I ever wound was a 833 kva. It weighed over three tons after I got the core irons and frame on it. Good video. Wish I knew what a trifilar coil was for. I have plenty of wire and aluminum to make coils out of, But I really don't know much about them other than knowing how to read a data sheet and wind a coil from it.

[Shanjaq]

Very handy! Hope you have a piece of Teflon tape on that equal button!

[codygillespie]

@Shanjaq

Excellent mechanical observation, i do have it protected : )

[mdbreedi]

Excellent video. Have been looking for something to wind some large trifilar Bedini coils and run across your video. Took a lot of your ideas and I am in the process of making myself one a lot like yours . Thanks keep up the great work.

[Jecha666]

calculator... uahahah

[redclaw4444]

your twisting idea is brilliant. I got feed up with trying to find out a way to do it the way i had my set up. So i just did to parallel and was more careful and slower.

[kjamesgraham]

Excellent job!

[FireBirdsGo]

Your coil winding jig is truly brilliant. Very well done! I am inspired.

[vid009]

Best coil winder idea I've seen so far, great job

[tectalabyss]

Smart very smart. Way to go !! Thank's for sharing. Tec

[AndreaGanora]

Really brilliant and smart idea the way you made the turns counter using a calculator, thanks 4 sharing

[coilsinamotor]

were did you get your gient spools of wire?

[codygillespie]

google magnet4less

[1stfreestuff]

the use of the calculator for counting is brilliant!

[blenderfreak112]

What awg is the wire?

[codygillespie]

i believe i was using 18 gauge in the video, but you could use whatever size you need.

[sparkfishes]

Brilliant!

 well done and very useful

Thanks for sharing that with us

[myself248]

Two dimmers to get the right twists-per-length ratio seems awkward, and since the diameter of the takeup spool is constantly increasing, it's something you'd have to be adjusting the whole time, right?

Using a capstan would eliminate that problem, and then the takeup spool could be driven separately.

Consider a gearbox (from a mini-lathe?) to allow a single motor to drive the bobbin turntable and the capstan at a fixed ratio to each other, for more consistent twist pitch.

Nice work, though!

[codygillespie]

You are 100% correct. Using a single motor with a gearbox would be far superior. I was aware of this i just didnt have the stuff to make it like that.  thanks for the comments

[tatter0035]

Cool Video

[codygillespie]

thank you

[spike2fei]

were did you buy the wire I need some of that

[codygillespie]

google magnet4less

go to that website and find magnetwire

[rroge5]

omg this is awesome, i imagion u could make some kind of mechanical thing to move the input wire back and forth to wind a neat coil.

where do you get your enameled copper wire?

[codygillespie]

thanks! You are right, many improvements could still be made. I get my wire from magnet4less, google it.

[electrician725]

Very Nice Work! Looks like a good under $100 build with some used parts. Maybe well under,

You should sell coils my friend!

-Rob

[codygillespie]

Thanks Rob! A little scroungin and you can make it very cheap, i did. As far as selling coils, i cant stand people who are always trying to sell crap and i refuse to be one of them. I encourage people to get their hands dirty and do the work themselves, you learn more that way : )

thank you for your comments,

cody

[electrician725]

U 100% right!!!

[InventorGadget]

haha creativity at it's finest! Wow i was just tihinking of how to get a trifilar made correctly and look , i just fund a perfect demo :D

[codygillespie]

Thank you InventorGadget! This michine does work but i might point out some improvements that might be made for an ultimate machine. Its difficult to get the motors running at a consistent speed together, a better system would have only one motor with two different gearings coming off it for the winding part and the twisting part. That way no matter what speed its running at you always have the same number of twists per inch. That idea was given to me by a friend, Good luck on your winder.

[hydro4f3a]

Nice work on the winder. Watch that calculator though... I had one that would not keep up with the drill motor.

[codygillespie]

Thanks for the tip hydro. I havnt had that problem so far, im usually winding pretty slow.

[dodoshlodo]

great Jig! why does BEdini twist his wire aswell?

I made a jig myself the other day, check it out:

watch?v=E0SHRLbdGVY

[codygillespie]

I believe the twisting is to insure a nice compact coil to get the best coupling to coil and core as well as best coupling between the separate windings if you are using it as a transformer.

[codygillespie]

I would like to correct my self here. I was reading over bedinis info again and found his reason for twisting the wire. He says its to evenly distribute the capacitance of the coil. Coils can have inductance and capacitance, just one more sign to me that these motors operate with resonance.

[electrician725]

Google LITZ wire for more info. Or look into the "practical guide to Free Energy Devices", it 'splains why Bedini "does the TWIST" :D
