This is awesome! So cool how you can 3D print virtually anything you need. 👍

[@mrrgstuff]

Thanks 😀 👍. Yes, the 3D printer allows so much to be built once you learn how to design your own parts. Everything else on this, except for the new reel of wire, was stuff I already had, so I didn't have to pay out lots on parts. I am very pleased though it worked as well as it did! 😀

Fascinating ! Thank you. You do very interesting work.

Thanks 😀 👍. It was a bigger project than expected, but I'm glad the coil winder did its job 😀

[@machineshopinagarage4699]

Nicely done, that is a very impressive device. Looking forward to the next video 👍

[@mrrgstuff]

Thanks 😀 👍. It was quite a big build for me, but fortunately worked with very little trouble in the end (except for the issues around the wire breaking)

[@matthewrichards88]

This is amazing.

[@mrrgstuff]

Thanks 😀 👍. It was quite a project! 😅

[@gmebit4329]

That's a rather superb little device. I would be interested in a longer video regarding the needlephone.

[@mrrgstuff]

Thanks 😀 👍. Yes, there will be a follow-up video from the Needlephone point of view, too

A very useful device, congrats on making it. Would love to know how they managed it in the 1920's under factory production conditions. That high impedance coil wire is so prone to breakages. Good to know such wire is found in clocks. Thought there were no uses today making it obsolete.

[@mrrgstuff]

Thanks 😀 👍. Yes, I wonder too how they used to manage things like this back in the day. The original wire did show some signs of being joined on the spool, so maybe it broke whilst winding back then 🤔. It seems impedance wire like this is still easily available, so presumably does have modern uses. Very handy discovery finding it in quartz clocks as initially I thought I would have to order another reel to finish the job

Nice coil winder tool! Now you dont have to wind the coil by hand lol.

[@mrrgstuff]

Thanks 😀 👍. I may well find other uses for it in the future 😀

[@modellbahnagenda]

👍👍👍

[@mrrgstuff]

Thanks 😀 👍

I would have liked to have seen where the break was.

[@mrrgstuff]

I don't remember there being definite breaks. I did look like the wire might have been joined when the coil was originally wound as the were paper layers, which might have been an attempt to insulate joins. With the old wire though, I wasn't able to get a reading at any point I tried. With coils like this, you might get lucky and find a break in the first few winds, but I didn't, and I made the decision fairly early on just to take off the old wire and wind new stuff. Thanks 😀 👍

About a hair's thickness

[@mrrgstuff]

Indeed. I meant to do that comparison, but forgot! Thanks 😀 👍

@@mrrgstuff at one time the smallest unit of measurement, a hair's breadth

[@neilgoloy3582]

Excellent! That's sheer genius in front of our very eyes, a truly impressive task. Well done!

[@mrrgstuff]

Thanks 😀 👍. Glad you liked it. It was quite a big project, and even editing up the video was significant, but worth it in the end, I think 🤔
