One does not simply watch a few minutes and save the rest for lunch break. Thanks Bud, there goes my morning productivity.
Well after a lazy start to a rainy morning, I was about to get up. However another coffee and staying in bed watching another Stefan video seems like a good idea. I love retirement.
Lucky bugger. I am supposed to be retired as well but all I can't get past the tired bit. 😌
Me too 73 and still at it
@@Agnemons To be honest I'm still doing odds and sods and getting into my workshop.
Retirement is a great thing
Me too, just made my morning coffee and went back to bed to drink it and saw a new Stefan was up, my day can properly start later. Being fully retired now my life consists of youtube and shopping for food to feed my badgers,😂
I used to make those for my scanning tunneling microscope in the 80's . That wire is a complete pita to mess with. I used electro etching in sodium hydroxide (drano) to make them atomically sharp.
It’s always a pleasure to watch you solve rarer problems, whether it be odd features, strange materials, or both.
This makes you fully realise the mad machining skills of Doc Brown in his wooden barn. No wonder it took him 30yrs from conception of the idea to the finished product.
Stephen you come up against some of the weirdest problems and then come up some pretty interesting solutions. Its an honor to watch your genius at work. In one word"SURGICAL".
It's an older meme, sir. But it checks out
Did you say i am old? 😁
Kids these days don't understand what the internet was like back then.
I can't imagine when I might ever have a need to straighten and/or sharpen a coil of thin tungsten wire, but now I know the proper processes to do so. Always learning something neat and obscure on YT. Thanks Stefan. 🙂
I am always impressed with your dedication to perfection in everything that you do. I always enjoy your videos. Keep them coming.
Thank you Stefan, interesting and instructional, a good lesson today. It is very weird stuff, and I expect it is very hard as well. Fascinating insight into bespoke machining and small shop production for what must be some very niche technologies.
What a glorious mane, and a lovely way to start the week.
"with pin point accuracy" 👍
that flux capacitor is going to run really smooth with those needles!
Wonderful to watch you at work as always Stefan.
very good job stefan..thanks for your time
you are an extremely patient man. nice job!
was very interrested in the red box on the table in the first shot. was kinda hopeing we would get to see and hear about it as well in the video
It's like it's Wolfram!
Thanks for another great video. I learn something new each time.
There is an old-school jewellers' method of straightening wire. It might work on Tungsten.
Bang a row of nails into a board in a straight line, with short distances between them - I would guess 15-20mm for wire that thin. Thread the beginning of the spool left-right-left-right through the nails, then grasp the free end in a wire-pulling pliers (or use a wire pulling bench) and pull the rest through. Amazingly, being pulled through such a "slalom" actually straightens the wire, as the bends tend to cancel each other out.
Might be worth a try if you have too much wire and some nails.
The reference for this technique can be found in "Metalwork and Enamelling", by Herbert Maryon, who was once curator of jewellery at the British Museum.
That process works on electrical wire as well.
This only works if the wire is ductile. The ductile-brittle transition temperature of tungsten is usually above room temperature, typically around 200°C. Below that temperature it will simply crack and split like Stefan demonstrated in the beginning.
The super finishing film is also used in woodworking for sharpening. I get mine in sheets of various micron sizes from Dictum in Germany or Wood Workers Workshop in the UK
A lot of new stuff, many thanks for sharing.
And quite stressful too, when you were twisting that thing on the lathe.....
cheers
thanos
That looked quite difficult, lot of steps to go through.
I imagine a very steep learning curve and not exactly cheap to 'play' with
I'm glad I don't make tiny parts like that from 'exotic' materials
Good video showing how it's done
These needles look exactly like the ones used for the Lampert PUK welder we used in jewellery school!
Geiger-Müller tubes are also used in UV Flame detection sensors/instruments for large furnaces in power plants etc.
Ahhh... the air hose holder finds a new role in life. 😉
Cool technique for straightening that wire, old school magic👍👌🇦🇺
0:57 "At that exact moment he realised he had f**ked up"
Sorry Stefan, I couldn't resist 😆Thanks for sharing the journey with us!
That was probably more fun to watch than it was to make them. Thanks for sharing! Hope all is well there. - TZ
You can also make a point on the wire using a solution of KOH in water and passing electricity through it (using a separate W electrode as a counter electrode)
Amazing work yet again Stefan!
The coolest element name of all. I found that cutting it on a drill press was very similar to cast iron.
Nice job.
Very interesting, educational and entertaining, thanks for sharing your work.
Always entertaining AND educational. 👍
Excellent work!
Very cool content as usual. Was hoping you would show the polished tips under the scope.
Tungsten: yes weird stuff .I built a helix winding machine (for TWTs) keeping the wire from fracturing was a major problem even with annealed wire. BTW is the Rapunzel look a wall climbing aid ?
Simple word….WOW….❤
Real nice macro filming on this one. I bet the camera work was nearly as difficult as the job itself. Well done.
Genius......................Cheers, Davo Australia
Thanks for sharing
That hair is getting to look fabulous
What would be a great video would be you sharpening a TIG welding electrode with this method and compare the arc shape versus a "normal" method of sharpening an electrode. To see if the arc shape and density is greatly affected.
A very interesting video. Thanks. Too bad you didn’t show the finished product under the microscope. I’m glad you had a nice vacation and escaped storm Boris.
Nice and instructive job as usual. As a chemist I know that tungstene is prone to oxydisation (it begins at about 600 °C). So using a reducing flame should be better to decrease the amount of scales?.
Thanks a lot for showing this stunning part of a flux capacitor👍🖖👌
Morning Stefan!
The secret mission to produce TIG welding tips for the mice?
Fascinating as always. Can you share the manufacture's name and part number for the polishing wood? I can understand that non-disclosure agreements may prevent this.
Fascinating to see how you straightened it.
Time to make a yoga bed with a few thousand of these needles.
I’ll get straight to the point. The juvenile humour potential is very high with this one but I’ll restrain myself.
I'm a lowly dead tree carcass butcher (woodworker), I get sheets of a similar abrasive from Dieter Schmid in Germany (type "fine tools" into Google and it should pop up). They are PSA backed tho (sticky back) so I dunno if it would work well on a lathe..... I use them for sharpening and lapping.
Jus sharin a possible source 😁

I think these will serve to make tungsten cactuses.
Hi Stefan, at the tip-polishign step, 21:44 , the velocity of the tip (against the polishing stick) is zero. The wear-rate of the tip too is near-zero, as evident from the "residue" left on the polisher. Would it be worthwhile, instead to have e.g. a Dremel-wheel (polisher with paste) with its axis orthogonal to the lathe-axis, and with some offset, of course.. Would this allow a tip-radius finer than the ~5-10um as you show?
Next week he puts a thread on the other end and drills a hole down the centre. :)
I’ll watch that!
And than a thread in the hole
Curious if that straightening method introduces a measurable taper - as you are pulling against the currently heated working area using the area you have already thinned slightly at one end it seems likely the thinned areas will stretch a tiny bit further than the areas you have yet to work on at all. Doubt it would ever actually matter for any possible use of these short sections of needles or really any other thin straightened wire that is not hugely long, but still curious.
Wow that's not obvious for sure, Im a little surprised they don't sell that wire in straight lengths
just wondering why you handel it with bare hands? no concerns about contamination?
Are there any machining challenges that you were not able to overcome and had to turn away?
liking the long hair
👍👍 highly engineered tig electrodes.
I have this theory. Since we've been hearing about this flux capacitor for years but have never seen it, the customer must be Iter.
Who knew you could straighten wire with an air hose holder?
Hello Stefan! What's your favorite brand of coffee?
Does the 1u diamond embed in the tungsten?
Thank you Stefan. Really interesting. I kept thinking how sharp they were, you probably wouldn’t feel it initially if you accidentally stabbed yourself. 😳. 👍🇳🇱
Ammunition for a flechette gun? ;)
Power supply? Would a car battery work?
Wayyyyy too much power. Heating up a wire like that would probably be 2-5v - I’d have to calculate the current… a car battery would turn the wire into a lightbulb (it’s the same type of wire that’s in old light bulbs. Although, I think light bulbs have more nickel in the tungsten wire.
👍👍😎👍👍
hmm. i don't hear much ventilation in your shop.
Thanks safety Sally.
@@grntitan1 you're welcome, Snarky Stewart
Might be time for a haircut, no?
why? i like them long and they dont have splayed ends.
19:30 I think I've watched too many of Tony's videos. I was waiting for the following sentence the whole time:
"For reference, this is a single human hair!" 🤣 Nice Video! 👍
