Developed in the 1500’s by the sea monks of Denmark, springs were originally created to bridge the gap between winters and summer
Today, they are really bouncing back.
@@alexgonzalez2338 These two comments are especially great if you read them together in your head in the voice of Brooks Moore from How it's Made.

You'll probably love This Old Tony's spring video.
😂
Yeah and sometimes its in the air.....
Of course you would polish springs to a mirror finish. Inspiring as always.
Ahh yes lapping down to .3 microns for me to just have it slip out of my greasy fingers under the bench and be lost forever! Thanks for the great content. Each step in this I was like “ what else is there even left to do to a spring?” Beautiful work..
I've made springs and heating elements on my 42" lathe for years. Never have I made anything that visually attractive. What an awesome demonstration of the craft and precision of a watchmaker.
Those are the most beautiful springs I have ever seen
Yep. The flat-ground and polished ends are gorgeous.
I was about to comment EXACTLY the same thing. Lol!
Even your springs are fantastic! Great work, Chris!
The most expensive, beautiful, heart and soul filled springs ever created. Everything you produce is incredible.
seemingly random question... could you make a spring from a tiny I-beam?
That notch in the wire trick is slick! 👌
Wow. Awesome. Not a spring, that’s a work of art 😊
Why yes I do polish the insides of my springs, what do you take me for, an animal? Mesmerizing work!
Wieder ein tolles Video. Vielen lieben Dank. Macht weiter so 👍
... if not flat out insane ... certainly psychologically atypical ... (luv it!)
I've never seen so shiny springs
I have made springs using 1/8" spring wire. I made a few of that diameter with beehive ends and forged a ball on spring wire to work inside the beehive. It was to replace parts that were no longer available for a fire truck.
Like alchemy!
Modern materials are wonderful.
Been watching your videos for many years and what you do is pure art!
this is the most extra thing i have seen in my life, im amazed at how it just kept going, seems like such a fun little project to tinker with
Are these springs clickable ? 😊
See what you did there 😂
Perfect as usually
Impeccable craftsmanship as always!!
has a special tool for polishing the *inside* of springs, which clearly has been used numerous times before 🤯
Chris, thanks! Have you considered making a crank handle that goes in the back of the spindle, where you might put a spider? Something like what Steve Jordan makes for his lathe?
As always, you make it look so easy. And you make a work of art while you're at it.
Even the damn springs are black polished. Outstanding.
Fancy sproing!!!
perfection personified, just love your work !
Thanks!
Cheers mate :)
Is this a shop tutorial or an art class? Yes.
Been watching this channel for years, just waiting for springs to be made!! About time.
Lol.
(Dear commenters, I am being facetious, relax)
It's not enough to make a perfect spring. No, it has to be a gorgeous perfect spring :) Very nice!
Wow... best springs I've seen made ever!
That jig that you used to level the top of the spring, Hand made or something you have bought. Never seen something like it before.
Gratz on 100k subscribers!!!
Thank you!
beautiful
Lovely to see your take on this video after watching Quinns a few weeks ago. Interesting to note the similarities and differences between them both and how your personalities shine through!
"shine" oh u
I take springs for granted- very cool that you can make them to spec.
100k subs, congrats!
I've seen springs made before but never that shiny! I thought it might have been a return spring for the plunger on the dial indicator until you made three of them so now I'm stumped.
Lovely job. Would it not be easier to polish the wire first? I guess there would still be some touching up to do afterwards after grinding.
Finally the springs. Do clicks next.
That's our job. Same with the Likes.
Just beautiful!
Beautiful work! Thanks for sharing!
I agree
finally some more springs on this channel!!!!! (boing!) ;)
Finally a vid of springs!
Beautiful work, although that tail stock center has seen some hard days
Excellent (of course) but that trick with the file was very nice.
These videos are beautiful. Well done Chris!
If there was an award for the most beautiful hands on CZcams, Chris would win hands down. Pardon the pun.
Nice to see you again Chris, but why no heat treat or did you just not show it here?
wow great work, that should get you the extra 700 subs you need.
Nice work, Chris.
Great watch. Thanks for sharing.
Oh, so that’s how uncle This Old did it!
Thanks Chris 👍
Great work
A masterclass, as usual! Excellent, Chris! Missed the narration, though.
If you want the narration go the link in the comments and watch the entire video.
I only wanted a replacement for the one I lost out of my Biro!
Made 1 with 3mt of 6mm rod - scary stuff thinking 'I hope my clamps hold' as I was bending it around. Needed spring for my thumbnail project. Nice detail on your springs.
Of course it’s a perfect spring.
very nice😊! what is your reason to first high polish them and than sand the edges afterwards?
🎵It don't mean a thing
If it ain't got that -🤭
Click?
Dayum, I wish I’d thought of that!! 👍👍
Doesn't the sproing need heat treatment, or is it already hardened to the correct sproingyness before winding?
It's music wire, it's treated spring steel :) that's why it bounces back so much after winding
I always thought that these get a heat treatment after forming to make them keep their shape.
Not gonna lie: my heart skipped a beat watching you polish the interior. I could just imagine the mandrel catching on the end of the spring and screwing it into the hand holding holding it.
Great Idea. I've been doing it the hard way all this time. Same results, just that twisting that wire by hand was tedious.
Can you tell me if you've figured out a formula for getting the needed outside diameter of the spring by utilizing an exactly sized inside diameter post onto which you wind your wire?
I could always end up getting my springs to come out "Good-Enough" for my needs but, I would like to have figured out some formula to get the outside diameters of my finished springs exactly where I needed them to be.
Perfection! Certainly puts my 3d printed arbor and piano wire wrapping tool to shame :)
Congratulations on a wonderfull job. A question: how do you protect your springs from corrosion?
Great
😂😂😂 When you put it in the Finger Clamp I thought 🤨 "Wait... Is he putting that in the MILL?? Talk about overkill... Ah. Nevermind." 😅
I never thought I'd see sexy springs, but I've seen sexy springs.
How do you determine the final inside/outside diameter of the spring given the quasi-random amount of springback inherent in the steel wire? I know there's probably tables and stuff to approximate it, but every batch is different, etc., so is this magic just trial and error?
The spring back is actually well understood. The diameter of a spring changes under load ,meaning that they can't be made to high tolerance anyway so the tables are always gonna get ya right where you need to be.
Machinery handbook has arbor sizes for piano wire👍🏻
Never thought of doing them this way. So awesome work there :)
Guess my question would be what calculations did you use to make sure it was right tension/length cause not all springs are the same, most i get made i have an actual spring place make them so it can be tested/made to correct spec
Design and Build Notes: 1. Build precision arbor so start wire perfectly fits under the shoulder of the cap screw head...with a ~thou overhang and the partial trough for the wire based on wire radius. 2. The diameter of the shaft has to be so many thou under the spring-back of the spring material to get the proper OD/ID final dimension. 3. The wire feed tube precision drilled and counter-bored to allow wobble from the spool. 4. Carriage mounting w/precision height set and feed rates engaged/disengaged for flats and spirals to determine overall length prior to flat grinding. 5. Grinding arbor precision turned to LN/LT fits of spring. 6. Grinding and polishing entire spring ID/OD to .3µ or 1.1811e-5"...Just forget about removing all burrs and sharp edges and get to work. ;-P Thanks Chris, Hope Santa was as Good to you as you are to us!
Thank you mate!
Wow ❤
TOP!!!!
You did not heat treat the springs? I cannot believe you bent Spring Steel that easily around your mandrel. So how well do those Springs work, or do they work? What type of Steel did you use? Beautiful workmanship and technique as always Chris but I'm a bit confused
That's why he's using a lever, to turn the chuck, instead of the bare hands
It's a youtube video. Ofcourse you can't bend spring steel so easly, even if it not heat treat. And without heat treat after you bend it (if you bend it) it wont work. No wonder he not sqeze it on camera.
Is there any practical reason to buff the springs or is it just aesthetic?
It makes the interaction with other parts feel slick and minimises corrosion - Cheers :)
Would it be easier and better to polish the wire before bending?
Polishing should always be the last step, if you want an impeccable finish
Next please make some clicks on lathe
Even his springs look like jewelry!
Does it clicks ?
Mr. click spring, doesn't that spring have heat treatment? Thanks!
The mighty spring. It pushes, or it pulls, but how do it know?
bonjour votre façon de faire un ressort et bien mais il faut le mettre dans un four a 320 degré pour le stabilisée si non il va perdre sont élasticité rapidement
👍
I don't think spring as polished as those are street legal in Norway?
Chris, is the spring wire being fed through the brass guide under tension or is it just ‘loose’ ?
Almost certainly there is some tension. You see when it was cut off, the spring changed diameter - tension was keeping it close to the arbor / mandrel.
The usual production process for springs is the anneal after the forming process to counter the work hardening and resultant stresses induced during that phase. Why wouldn't you do that here?
That's for big springs.
In no moment of the forming of these small springs the metal has gotten hot, nor has been subjected to big mechanical forces... so no work hardening. Metal alloys used in springs are specially formulated, and heat treated, to not harden during forming...at least in springs of this size
Every prepper is gathering food, water, guns, and ammo; which ones are preparing for the loss of availability of springs? Where will you go when the springs run out?
Seriously, that was beautiful. I've seen springs made on How It's Made but never slowed down, and on a small scale.
I would put one of those springs on my keyring and cherish the craft.
Don't they have to be heat treated? Won't the steel deform and fail?
I too polish my springs....
Perfect springs but with a major flaw, they did not click.
How do you know it would make your desire spring rate?
Hey, out of curiosity, shouldn't these springs get heat treatment after the winding? When I was in a spring factory they told us that after winding the screws go to a furnace where they get basically tempered, otherwise they would quickly deteriorate.
Source stock is pre-tempered music wire so a temper cycle would certainly relieve any residual stresses. However use case here is light service, low range, compression only so I judge it not necessary - If use case were average or severe service/high range/dynamic load etc, different story- Cheers :)
@@ClickspringClips i see, thank you! Great video, love your content.
It's there a way to make a spring so curved a toothpick won't pass through it's axis?
Indeed there is. Many years ago I worked on IBM Executive type bar typewriters which had pawl springs that were about 1/16" ID and 3/8" long, and were a real pain to replace.
yes look at the spring that holds the flint in most lighters, much smaller ID, and theoretically possible to make a spring of any ID
Is it ok if I don't mirror polish my springs? 😁
Heat treatment ?
"How you do anything is how you do everything."
That dude in john wick was right.
think you polish the swaff from lathe too unless you be seen dumping rusty off cuts 🤣😁
Do you do any math to figure out what angles, turn counts, and diameter will give you the desired spring coefficient?
Yes, there is a comprehensive section in Machinery's Handbook covering all of the design, math etc - Cheers :)
