Tempering spring steel, blacksmithing, bushcraft, forge.

[@PICing4fun]

Great video man! You're the kinda shop teacher we wished we all had in school.

[@CP-pf6gx]

Yeah, 13 years later but, if you hear me out, thank you very much for that fine presentation.

[@user-ix1gh9dp2p]

Hey, Big Ditto on THANK YOU. I had a spring clamp on my grounding welder lead, that had totally lost its springyness, making the grounding clamp useless. I crudely followed your wonderful video with two propane torches, a magnet, used motor oil, warmed, on a propane camp stove, and even clueless, I still got positive results renewing the coil spring in that clamp. I looked HIgh and Low for a video like yours. So glad I found yours. So Appreciative, Mo

[@casinogiant]

Well made video with good explanation, without all the boring extras.

[@kurtisacevedo5911]

Excellent presentation. I came for the info, stayed for your voice. Thank you sir.

[@johnrees44..G4EIJ]

Thank you for a most informative video in laymans' terms.. It answered all my questions without me having to ask them!!

[@frankiepips]

Cheers mate it used to take hours to find out what you just portuned in a library my man? Hats off ! ;)

[@skygh]

Thank you for taking the time to make this great video. A little better lighting would help but I am not looking a gift horse in the mouth here. I learned a lot. Top notch.

[@hughbuchanan9048]

A good explanation and demonstration of hardness versus toughness. I need to be able to make flat springs for my locking folding knives. Your video confirmed what I had thought to be true. Many thanks!

[@sethwarner2540]

you may not know, sir, but you are a gentleman and a scholar(and there's not many of us left!). there are many who can give a proud answer, but few who can give a humble, accurate one. Thank you. Please make more videos.

[@lemontier]

A really nice job of explaining the process. Nothing but good solid information. Thanks for your effort, you are an excellent teacher.

[@aaronrheams2920]

You explain this process perfectly. Thank you.

[@dantehendrix314]

I realize it's kinda randomly asking but does anybody know a good place to watch new tv shows online?

[@kaysonmalakai3711]

@Dante Hendrix Flixportal :P

[@dantehendrix314]

@Kayson Malakai Thanks, signed up and it seems to work :) I really appreciate it !!

[@kaysonmalakai3711]

@Dante Hendrix You are welcome :D

[@JD.tsuki22]

Why is Freddy Krueger explaining blacksmithing to me... and the weirdest part was this answered my exact question in detail🫂

[@scottleft3672]

BEST ....simple and strait forward vid ive seen yet....owe eye.

[@express375]

Exactly what I needed. I'm making a spring for a pen knife. The first one had a slight bend in it after quenching from critical. It snapped as easy as a biscuit :) What's funny is i kinda knew it might snap,and i still tried to bend it. I wasn't sure if i quenched it again after the tempering.This is the exact answer i was looking for.Cheers.

[@driton1448]

No messing about and straight forward. Very helpful, Thank you!

[@MrSuperMation]

Thanks for sharing your experience. I was needing a simple explanation that I could understand. I look forward to seeing more of your videos. Thanks again

[@braedinn]

excellent video,,ya explained it in terms even then non-blacksmith can understand,,,looking forward to more

[@mrmuguee]

Great video, best explanation on tempering I've seen; please post more videos.

[@velvetelvis6839]

my search is over.great video.answered all my questions

[@richardjoyce1102]

Same I didn't expect much because it had a thumbnail like other videos that weren't what I needed

[@bikingnutcase0]

That's a good video! I'm used to hardening/tempering, but I'm making a spring at the moment and having real trouble getting an even heat at the tempering stage because it's really thin! What I found useful about your video was where you pointed out that the steel can look blue when it's still not quite up to heat. I'd not thought about that before, just assumed it went straw, brown, purple, blue, and blue was correct. So now I realise that, I'm thinking more heat! Thankyou for sharing!

[@rrnsss]

thank you so much for your nice video. Every thing was explained in an easy to understand fashion, simple and with examples. Hope you can post more videos like this on forging process too, for beginers like me..

[@BrotherPhilo1958]

I enjoyed your video. I hope you will make a video showing the proper process to temper a knife blade. Some videos recommend placing the knife in an oven at 350 for a couple of hours but i think that will make the edge soft. I hope you have the time to show the proper way...Thanks

[@OttoDeCalumnias]

VERY illustrative and down to the ground. Great stuff, love it.

[@jessesinclair4491]

informative without being hours long, enough well explained information for one to proceed, only recommendation i can make is video quality be it the device or format a clearer picture would be helpful for those who weren't confident they interpolated the description given correctly. otherwise a great video thankyou.

[@indianatone218]

very informative for the beginner straightforward talking enjoyed most usefull thanks antony

[@TheOdie63]

Great video! Thanks for sharing your skills!

[@tenglundvideos]

Cheers from loxahatchee FL. 2 words for your video Absolutely Perfect!!

[@theloniousm4337]

The video was helpful and very well explained.

[@thoordog]

Finally.... A video the explains the differences in simple terms!!!!!

[@joshuanewton5015]

Thanks for that video I loved it! It helped me no end, I was doing tempering for an assignment and needed some tuition, cheers lad! Keep the videos coming and STAY DENCH.

[@MrRander7769]

That was information I have been looking for a long time. Thank you for sharing your knowledge.

[@Suntzudao]

I just caught your video. That was very well done, very little embellishment, with very clear examples. Thank you for the time you put into this video. Now I am curious about your social commentary. :)

[@quintin636]

thanks!! i've seen a lot of video's of tempering and hardening!!! A LOT!!! and non of the video's explained this good. NON!!! now I understand it... THANKS!!!

[@gt0915]

Fantastic video, basic and to the point.

[@hshakirshakir8603]

Very clear and straightforward

[@runningmangray]

A brilliant and very informative video, thanks for taking the time to make it, cheers.

[@mrtechnophile3483]

Wonderful video, thank you for posting it! Looking forward to seeing more of your videos.

[@cliffordwilson4271]

you are a great teacher my friend.

AISI/SAE 9254 is the common spring steel (and cheap). Tempering is 2 steps process. First you do quenching ( 45 mins at 870 celcius to reach austenite point then cooling in oil at 80 celcius) , and then you can temper it 150 - 250 - 350 - 450 and 550 celcius. Let it cooled down in room temperature. And a tip, would be great if you coat the steel with copper. It will prevent decarburisation and after quenching and tempering you will see the copper will come out by itself.

[@russellheyns1846]

Thank you so much. You explained exactly what I was looking for. Great job.

[@valtito9297]

thank you! I've been looking for the answer for this problem for a long time! bless you

[@nontimebomala2267]

Thank you sir! Just what I needed to know to modify that spring from my BSA Lonestar hammer.

[@southjerseysound7340]

Great video,all of what you need to get stated without the tons of bs some use to try and scare folks off.

[@herenow2895]

Brilliant. I really liked this video. Very educational too.

[@bone0944]

Excellent video conveying the important information clearly and accurately. You could do with a better camera and lighting to improve the video quality, but your delivery was first class. I look forward to watching more of your videos.

[@timthompson3958]

Thank you. I am hoping to make me a fillet knife from some leaf spring. I hope that returning it to Spring temper will make it a superior fillet knife.

[@DIYweldingPlans]

I'd like to see a video on how to make/temper a knife like yours in that video. Thanks for a very informative video

[@Coolarj10]

Wow, amazing video!!!!! Thank you!

[@Mbonner73]

Great video, thank you for posting this

[@Lst2ltdwn]

Very good explanation of the process, thank you!

[@joblessalex]

Thanks for the video!! I was looking all over to find a straightforward tutorial on how to do this and this one worked great! Would like to see how to harden just the knife edge and leave the rest tempered. Every time I try to do it the rest gets too hot and I have to retemper it.

[@diarmuidsynnott]

thanks for the straight forward info! putting me on the right track.

[@howshawthebrave]

@NaturalBushcraft Thanks Ashley, It means a lot coming from you.

[@1stngl]

@howshawthebrave WOuld be very nice if you would do the vid about selective tempering for a knife ...seen a lot but would be very interesting to find out your approach in the same simple, easy to understand manner. Thanks!

[@mrvoodoo94]

so i can go ahead and work with it? shape it get it ready grind the bevel leaving enough there for heat treat. so when i heat treat it get it to non magnetic then temper in the oven. Wow thank you for replying

[@HunterOrock]

Great video. It was very well explained.

[@IIDASHII]

Water cools steel extremely fast. For certain steels and situations, it works, but it is usually a risky quench, as the stress it puts on the steel can warp and break it after you have put many hours of work into shaping it. Mildly heated oil is a much safer bet, and provides a good enough (and in some cases, ideal) quench for most applications.

[@blightcraftgamma]

thank you. was very good. that old file went to a good cause

[@Bangalangs]

Very descriptive. Thanks for posting this video

[@taloskriti]

Very nice educational video !

[@wrazni]

Excellent video , and very well explain

[@noxagol]

You can also take two pieces of spring steel and weld them to the sides of a piece of tool steel, like a sandwhich. This will give you the toughness of spring steel and a hard tool steel edge

[@johnny5fingers0966]

Thank you for sharing your knowledge!

[@joblessalex]

Thanks! I was making a 2ft sword for the fun of it out of some annealed spring stock and this did very well.

[@nobodiesful]

thank you for your time sir

[@Disthron]

Hay there, not really what I was looking for but still very interesting. Grate video.

[@Guitardude1616]

if you made a knife out of spring steel and then put it back to spring steel would that be tougher then tempering it regularly? it would be very hard to sharpen but you wouldnt have to sharpen it very much. so would that work theoretically?

[@howshawthebrave]

Spring steel is already workable so you don't have to anneal if you are just shaping up with a file. If you want to anneal it though, just let it cool from bright red, one the side of the fire.

[@mojothemigo]

Spring steal=leaf and I think coil springs of most cars. The part used in the video looked like in came from a coil spring, very handy thing for making your own cold chisels. I think most cars here in the US use a specific spring steel, 5160. I wouldn't be too surprised if your part of the world they use the exact same thing with a different brand name. Anyway, if you find an old car spring of some sort, you have a very high chance you found the right kind of stuff

[@drewdavidson5611]

Thanks for sharing. I always wondered about that. Can any oil be used as in old motor engine oil or synthetic engine oil ?

[@SsjSned]

i would like to see a vid on that knife process. tkx ur vid was simply great

[@diverjhonny9345]

nice video, I try one cooling on hot salt water, salt helps to transfer heat. then annealed the blade from an old truck(?maybe not). was 6mm thick, I was willing/guessing the blade was going to have diferencial hardening. so, the blade end superficialy cemented. I couldnt sharpen it, 20 years ago, I didnt know how, took it to a knives store to get sharpened, was my first knife, the result was amazing, never broke or chip (my fear) my dad ones chopped a zink sheet (w. out my ok), no damage!

[@huntingsgr8]

heat it up to quenching temperature and allow it to air cool or if you can find some insulator that can withstand high heat wrap, cover, or submerse the blade in it the idea is that it cools as slowly as possible.

[@howshawthebrave]

@Development2112 No. The blue is a temp indicator that appears as you heat the steel. Before we had blowtorches this was done in the forge & the room was very dimly lit. Much harder to do though.

[@TATTOOTRAINING]

but the colors are straw, purple , blue then light blue and then white , is the blue you are speaking of past the light blue/white ? i want to harden literal spring steel .018 thick

[@CraigArndt]

Awesome, just what I was looking for. I'll add this to my favorites.

[@caemaridwn]

Nice video thanks for the info keep it up

[@backyardblacksmith3090]

Great video sir thank you for time and effort.

[@howshawthebrave]

@MrGRINandBEARit You can quench it. It's not as critical for spring as it is for a blade edge. That's a bit mome complicated because you need to graduate the tempering whilst retaining an edge.

[@tobyjo57]

Very helpful and informative. Thanks

[@Christh2008]

Thanks, great video professionally explained great job! Just a question, can you begin with mild steel and add carbon to it?, then harden and temper it?, if so how would you add carbon? Thanks Chris

[@howshawthebrave]

@StGeorgeTemplar92 It should be fine. It won't bend or snap & if you can temper it evenly it will hold an edge.

[@davidjames1007]

Great video, thanks for sharing. I want to make a compression spring from 1mm steel wire. How would I harden and temper that? Your advice would be much appreciated.

[@alexrobinson2921]

Hey man Im looking to make a knife blade out of nickel iron meteorite, though before i invest in the meteor i was hoping to find out weather it'll be too soft, if so would it be easy to temper without melting it, ie changing the Crystal structure as it has a pattern called the weatherman pattern and im hoping to sustain it? Cheers

[@ImaHooka]

Hey man, Im currently doing my own little project where im making a bow. Im stuck between using aluminium and spring steel for the limb of the bow. The limbs need to be flexible but they should have a good elasticity and be able to return to its original shape. Which would you recommend?

[@howshawthebrave]

@newtubetubetube You can use a blowtorch yes. Preferably in a small hearth of fire brick. You can't get the temp with just coal & no draft though. I use charcoal & I make it myself. Try searching bushcraft forge on youtube. It's easy to make a basic outdoor forge. Loads of fun too!

[@jyotitekwani6699]

nice explanation. please let us know how to flat spring steel plain washers. which are non flat and

[@Friedrich-Wilhelm-1980]

ok so you need to start with carbon steel heat and shape then harden with heat crit temp and quench then anneal to reduce brittleness? so it i wanted to make small coil springs that would work for that?

[@ScoutD300]

I need to weld two pieces of spring steel together. I did that with some 312 stainless rod. I heated it to cherry red and quench in oil. But now see I missed the temper part or heating it dark blue. Question: How long does it need to cool on the stones/forge after tempering? Thanks for making the vid too.

[@michaeldeluca6852]

Great video! I want to make a froe from a leaf spring so needless to say, seeing you holding a froe and talking about the properties you need for one ( temper the froe back to spring steel) was like hitting the jackpot. I am still trying to understand how to heat treat steel, in this video it seems that you just air quench? I understand you first harden the steel ( get steel hot enough to become non magnetic and oil or water quench) but I thought that in step two: where you heat the second time to the appropriate or desired tempering temperature, that you once again had to oil or water quench? I like the the idea that I may be able to just air quench as you did. thx for the video!

[@GunnySGT1911]

Thank you for the great instructional video.

[@VisayasMindanaoLuzon]

It will just only brittle right? What will be the other problems if I didn't temper a knife? Thank you.

[@pir869]

i need to make a small torsion spring,i bought some spring wire .8mm,it was under 3 quid for a metre so i can try a few methods,should i harden and oil quench as you did in the video,if so,it will be quite difficult to remove the oxide layer formed,would pickle paste be ok,i've used this to clean stainless welds,ive noticed some sort of residue after cleaning,bearing the parts can be wire brushed or grit cleaned,the small spring has 3 coils,would this need to be heated in sand with a k-type thermocouple. I watched some other vids ,one had small parts in wire wool in a household oven. like i said the wire is cheap and i can suffer some practice,any advice to acheive a simple easy temper(not a few ales) would be most appreciated. You cleared a point for me,and that was let the tempered part cool,not quench,like allowing cast iron/steel to gently cool after a weld. All the best from me john henderson in glasgow. cheers.

[@CraigArndt]

Great video, very helpful.

Thanks for this. Just what I needed to know.

[@billab0ng83]

brilliant video. well explained. appreciate it.

[@bealzebub2077]

thanks for this video! im making a viking sword from an old leaf spring and i need to know this!!!

[@hasdrubal121]

Well explained and easily understood.Thanks

[@frankgonzalez3822]

Great video. Would like to have an idea of what temperature you warm the oil? So I can harden a knife, clean it up, lay it spine first / edge side up on the hot coals and watch for the blue to creep up from the spine toward the edge. Remove the knife from the coals when the blue gets halfway up from the spine and edge. This should give me a softer spine and keep a hard edge.

[@eddiesblacksmithingkjv9185]

Frank Gonzalez I warm my oil to approximately 120 to 140 degrees farenheit
