Bill K: Cool!! This will work great for a tattoo machine coils. I would suggest
for the single coil spool to have a bottleneck plate with 2 rubber door
stops to create drag. Or at the end of the all thread where the spool is
mounted, or you could create drag on the shaft. With PVC pipe & a lock nut

NasGaming92: lol gj well thinked that calculator will do the same :D
Bobby Tectalabyss: Smart very smart. Way to go !! Thank's for sharing. Tec
Myron Breeding: 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.
codygillespie: thanks! You are right, many improvements could still be made. I get my wire
from magnet4less, google it.
Helmy Yehia: good clip
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.
Jecha666: calculator... uahahah
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.
codygillespie: @Shanjaq Excellent mechanical observation, i do have it protected : )
Gary Graham: Nice work on the winder. Watch that calculator though... I had one that
would not keep up with the drill motor.
Joseph Germany: 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
FireBirdsGo: Your coil winding jig is truly brilliant. Very well done! I am inspired.
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.
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
Inventor Gadget: 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
JRBeaman: Explain why twisting two wires together helps your circuit, or any coil,
for that matter, please.
77GSlinger: freaking brilliant! Thank you!
tatter0035: Cool Video
Sutthi Rungsrirattanawong: 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
kurdishmob: kholy crapz. ur da man.
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.
GHOSTTOYS: ingenius hahaha
codygillespie: google magnet4less
Shanjaq: Very handy! Hope you have a piece of Teflon tape on that equal button!
rockethead555: Hello!, good design . . i was coming up with something similar but never
thought about the three coils mounted in a circle like that. . haha smart
trick. Anyway talking about number of turns for a given Inductance and a
given wire length for a predetermined "dc resistance", i see it would be
hard to determine with the twisted wires approach say for a bifilar or
trifilar because that design uses more feet of wire versus straight turns
of wire.. so how would you calculate the L for this ? thanks
vid009: Best coil winder idea I've seen so far, great job
dodoshlodo: great Jig! why does BEdini twist his wire aswell? I made a jig myself the
other day, check it out: watch?v=E0SHRLbdGVY
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.
Marneus Calgar: Very well done sir :)
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
blenderfreak112: What awg is the wire?
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: 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.
Gort Newton: Very nice. Love the simple arrangement, and it is very effective. What do
you use the trifilar windings for? Also, a spring-loaded tensioner between
the lower coils (the feed coils) and the take-up spool can make the winding
coilsinamotor: were did you get your gient spools of wire?
codygillespie: i believe i was using 18 gauge in the video, but you could use whatever
size you need.
Myron Breeding: 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.
Andrea Ganora: Really brilliant and smart idea the way you made the turns counter using a
calculator, thanks 4 sharing
codygillespie: google magnet4less go to that website and find magnetwire
spike2fei: were did you buy the wire I need some of that
Matei Bogdan: it's like the gear wheeles the little one is spinning faster and the big
one is spinning slower . same is the principle at bycycle the report is 1
turn at the foot wheel and 5 turns at the drive wheel. To pedal slow and go
faster. Excuse my bad english!
electrician725: U 100% right!!!
codygillespie: thank you
Sutthi Rungsrirattanawong: 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.
electrofly23: for a counter I used a digital pedometer from the dollar store - I wired in
a reed switch and put a small magnet on the motor shaft. For speed control
I used a footswitch from a sewing machine - it works like a gas pedal from
off to full speed - no need to use a dimmer.
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!!!
1stfreestuff: the use of the calculator for counting is brilliant!
Ben Silva: this is pretty freaking awesome
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
