Ralph's Amazing Coil Winding Machine

[@peter-vk3acz]

Wow! Glad it’s not very complex… thank you Ralph - and Peter - for bringing it to us. Cheers.

[@gfr2023]

what i like most is the reuse of others part and the building with hand tools.

[@radioboyable]

what a cool little devise.

[@youtubeaccount931]

omg that is awesome. Well done Ralph!

[@alanhughes1262]

Some great finds at ham fests that's amazing .Ralph thinks outside the box brilliant.

[@Brandon-xe7vy]

Fantastic build!

[@davidportch8837]

Absolutely wonderful piece of homemade kit.. well done Ralph and thanks Peter for sharing... the information about the polished steel rod price and obtaining it from old printers was very interesting...

[@DonzLockz]

Holy cow, thats amazing and top quality!😮 What a champion!👍🤠

[@SergiuCosminViorel]

what about the cows?

[@Jxmella1560]

very interesting, really! An amazing piece of homebrew !

[@creative27feb]

Awesome,👍🙏

[@VK4MUD]

One of your best videos Peter.

[@vk3ye]

Yep. The less I talk the better the video.

[@Physco219]

Of course there's beer can bits in it. Ralf, you're an amazing lad. You need your own channel or site for this stuff. I have no doubts there's a lot more you've tinkered with besides this winder. Let's see the rest, mate. I'll be more than glad to pitch a few quid your way to see.

[@vk3ye]

Thanks for your comments. Ralph's website is here: users.monash.edu.au/~ralphk/

[@andrewandrosow4797]

Good job! The highest quality factor has a basket coil or a coil with big distance between wires.

[@nickkendall3764]

What a genius

[@Meccanokinematics]

Nice work. You should have used the FAC system to make this machine.

[@alexhernandez8012]

I just got flashbacks of loading these coils onto my cnc press brake lol

[@Steve-GM0HUU]

👍Ingenious. Credit to Ralph for constructing this with just basic tools. Next project could be a time machine to travel back to the 60s and buy one of the MoReCo machines for 75 bucks. Mind you, Ralph's version looks like it might be better?

[@notionocean]

Love it! Waiting to see the toroid version.

[@FarleyHillBilly]

Try cotton covered wire for wave winding, and no beeswax. Add a touch of thin diluted polystyrene in acetone, from time to time, to secure the winding.

[@jamesu1540]

Love handbuilt machines, what about using Meccano?

[@vk3ye]

The tolerances in this need to be 0.1mm. Screws like in Meccano aren't good enough. Need rigid pins for placement, screws just for mechanical support.

[@jamesu1540]

@@vk3ye the question was of course tongue in cheek. As a 50 year old. It looked very much how Meccano used to look like when i was a child (not the current nonesense). Great channel as always.

[@hobbyrob313]

Very nice! BUT somewhere on Y.T. I have seen a simpler version that also did very well! And you can also make anything with 3D printing these days. Regards Rob

[@SergiuCosminViorel]

Thinking about doing without so much at disposal... for example without "cornerstone"... just one rotating shaft, and two electromagnetic relays, optical comand, from the shaft. I did not do, so i do not know how well it would work.

[@BEdmonson85]

Make the ratchet bar out of some delrin tube (or put a bit of heat shrink over the current bar) should quite it down a bit.

[@joeshmoe7899]

How did he resist the temptation to motorize it?

[@TurtleWaxed]

Why not make a level winder instead of a zigzag wind? Make it go full row of turns then return between the lower layer on the way back. You only need a direction changer at each edge of the form. (most useful for larger diameter magnet wire). Fine magnet wire may be better wound the way you are doing it?

[@vk3ye]

That question's above my pay grade. Ralph made what he could out of parts he had available and it works very well.

[@INFO_SELABX]

Noisiest winder
