Je veut une autre matière pour le ressort

The thin blades of old hand saws are great for those little sear springs on flinties. I also pounce on old car and truck springs and have a stack of them in my workshop. Coil springs from cars are good too, but need a lot of forging, which I am OK with as I am an ex-farrier and have a big anvil and a large gas forge....

Cheers Buddy. Now when are you going to start uploading your prop making videos? :)

Thank you.

Thank you. Much appreciated.

Thank you.

Hello, Its just a standard hob. It is a rough and ready way to get up to the 300C or so required to temper the spring and take out the brittleness. Its a handy way of doing it as it will never overheat the spring and spoil the hardening.

It's a little stake anvil. I mostly use it for making arrowheads. It was one of those things I found in a box of old tools at a car boot sale about 20 years ago. This was before blacksmithing became popular so I only paid a few pence for it.

+spanky stang On light work a panel beaters hammer gives a lot of control and is well balanced. I just polished up the face a bit. The little stake anvil is one I have used for many years for making bodkin point arrow heads. Can't remember where I got it. But it's very solid for its size. Much heavier a than the average silversmith anvil. Thanks for commenting :)

Swallow Forge it looks like the one I just finished forging, coincidentally. Is it odd that I keep a smithing kit in my car?

O fogão elétrico foi para fazer o revenimento da mola, não a têmpera.

@@sandroventania782 Right, Thank You. but I really wanted to know what brand of hot plate or electric hob was used. BTW, my spring turned out great.

​@@Tids1960usou um fogão elétrico também? Eu fiz essa semana uma mola usando o fogão elétrico e também ficou ótimo!

@@sandroventania782 I have a wood burning stove that will hold four 3 to 5 inch logs two foot long. I have read temperatures above 400 degrees with a digital thermometer on the top of the stove. I use that to heat my shop, and coffee, during cold winters. I'm glad your spring came out good for you, it took me two tries for me to get a good workable spring. It truly is an art.

​@@Tids1960Tentei o fogão de lenha, mas não obtive sucesso, acho que meu fogão não estava na temperatura certa. Sim...fazer molas é uma arte!

Long as it's high carbon it should and from what I know they are lawnmower blades work aswell

It all depends. There are good quality blades and bad ones, same with springs. I tend to go with the sound of the steel. If it gives a good sharp 'ting' when tapped, it usually indicates a higher carbon grade. You can get obsessed with grades and bogged down with hardening and tempering quench medians ant time/ temperature charts. The gunsmiths of yore had none of these things, I like to keep my smithing organic. Sight (colour of the steel over temperature) sound of the steel to help determine grades. But most of all how the steel is worked. I have made countless springs, all from steel from different sources, not to my knowledge had one fail on me yet. :)

@@SwallowForge What brand of hot plate did the gunsmiths of yore have?

Hello Nick. Sorry to hear you are having problems. It often depends on the steel you are using. It may be that the steel needs de stressing (annealing) before you work it. Take it up to a cherry red for 5 mins or so. Then let it cool slowly. Work the steel then harden ( easy way is to take up to a heat where it becomes non magnetic and quench in oil) for a relatively fail safe temper, take your oven at home up to its hottest heat (around 300deg C)and leave the spring in it for at least an hour. When you fit the spring it is very important to work it slowly before spanning it fully. Take ten to twenty minutes working the spring back and forth, taking it a little further in stages. Hope that helps, if you are still having problems contact me on my facebook page and i can discuss it further. facebook.com/swallowforge

@@SwallowForge Hello and thank you very much for the reply, I am using new spring steel stock 4mm thick. I do not know if it is stress relieved from the factory but I do 3 normalization cycles before the quench. The main problem is that my oven does not get hotter than 250 C°. The first spring I attempted tempering by using an old gunsmithing method by submerging it in engine oil and slowly heating it over the fire until all the oil burns off then dunking in in the oil for the second time burning it off again then finally cooling it off in oil. This method works great for sear springs but the first main spring broke exactly at the bend. The second mainspring I had to anneal and quench for the second time because I did not adjust it properly to fit the tumbler and in the first temper I kept it in a can of burning oil for 30 minutes and it seemed to work well I compressed it many times and it held it but for the second time tempering it broke again at the bend. I am building the whole right hand lock from scratch for a 4 Bore Double Gun I'm making , You can see videos of the proof test on my channel if you are interested. Thank you again for your time and willingness to help.

Bring it up to 1500 degr bright red just over non-magnetic and let it air cool three times. When you were heat treating this has to be done before you quench in anything you're doing whether it be a hammer a spring a knife it needs to be done this is called normalizing and helps refine grain structure. Then quench in cooking oil from just over non-magnetic there's no need to go to bright yellow like this dude says. That's very bad for the steel. After you've quenched it temper it. Somewhere between 5 to 650 degrees A nice blue color.

@@EthanPDobbins Hey Ethan, I do normalize the springs three times before I quench them, and I get them just above cherry red slightly into the orange when I quench I found out spring steel hardens better this way. But tempering them is very hard I found out today that probably the best way to do it is over a hot plate, polish the spring so you see the colors and heat it until you reach a pale blue, and you need at least two temper cycles in order for the spring to not break, and for thick mainsprings three cycles just to be sure. Cheers. Nick

MMM.... temper it a bit softer.... but a mistake often made by beginners is a function of their speed. Holding steels of this kind at high temperatures for long period causes changes in grain structure that cannot be restored by working. Use only enough heat to work the steel easily, avoiding yellow heat if possible, and use as few heats as you can manage. That gets easier with experience. working steel on an anvil is an art. I usually temper my springs, after an oil quench from cherry heat (dead hard) by heating them in the flame until the oil just burns off....no more. Repeat that three or four times and you are usually good to go. I use used car engine oil which give a lovely blue-black finish which is as good as a factory blue. When making and finishing the spring, get as high a finish on it as you can. Rough finishes mean thousands of little stress points that can be the start of an incipient break. Good luck... :-)

You can heat treat it again. It never hurts to anneal first though. That will relieve any stresses in the steel from your last attempt at heat treating. Did you check to see if a file would dig into it after the quench? If you did a proper hardening, a file won't bite into it. Not sure on temper colors, but I temper springs to a blue color

I found out it was because of a bad materiel, so I found another one, tried to harden it and found out that´s the one.

@@KeithBair yes I tried it, but I thought maybe I am a laic who doesn't see it right. But a new material is from a saw blade, I tried it and it is right material. I still didn't anything more since, but I will try to do some spring again. Also I will anneal it first this time, thanks for answer! :-)

ok what steel did you use?

What country are you from?

If your in England, that's a hell no.

Landon Swallow Forge is British, you only need a license. I own many perfectly legally.

Oh, I was talking to a friend who lives in England, and he was said you cannot own a handgun unless it was made before X date or whatnot.

***** United States

The cordless grinder I'm using is one of the best grinders I've ever used. This isn't a payed product endorsement. But the Panasonic is top class. Plus the balance is spot on, making it far easier to cut straight. Plus the corded grinders (of which I have many) regardless of how careful you are, the cords always seem to get in the way. Final point is buy decent quality slitting discs, they will last longer.

+Swallow Forge had a similar problem with my hedge trimmers and mom's longest extension cord that I borrowed..

Tudo certo amigo vc faz essas molas?

Estou tentando acertar com aço 5160 uma mola V de um sw 32 não tá fácil

Spring steel needs to quenched in oil otherwise it may crack as it cools too quickly in water. Its to do with the alloy of steel used.

@@spwicks1980 yeah that is an old opinion but untrue, the opposite is actually true. When you quench hot steel in water, the water vaporizes around it giving very poor cooling. Oil on the other hand is very good at transferring high heat and you get a quicker quench.

@@allansmith6140 You can water harden certain steels without issue. Basic 1080 steel is water hardening. I used it a lot as a kid for tool making. The trick is to keep the steel moving to prevent the steam jacket as even water queched steel will crack.

@@spwicks1980 I'll agree that it helps to know what one is doing ;) I once experimented with cracking various steels on purpose by various quenching methods just to see for myself. What I found that its not that easily achievable and that it was more related to poor preparation methods before quenching. By cracks I mean non-visible cracks that later caused failures during testing. I've never seen cracks visible to the eye or have had things break apart when quenching.

The original broke because its geometry was incorrect for the lock. I fixed that issue. 😊

Better if you learn English you will discover a lot of videos like this explaining the processes of forge missing parts

ATF? Whats that?

Swallow Forge the BATFE(usually abbreviated as ATF) is the Bureau of Alcohol, Tobacco, Firearms, and Explosives. It’s an American bureau. They basically interpret the law from the government to decide what is and isn’t legal with regards to guns, alcohol, etc, and then enforce those laws. It’s kind of funny, because even if you were in America and subject to the ATF, they literally could do nothing about this since it’s legal to make your own firearms in America, as long as the guns follow the current laws, and along with that, black powder guns that don’t use metal cartridges aren’t even considered firearms by law.
