Don't feel so bad I've had so many projects go south on me. Like today I was able to salvage a piece that should have gone into the trash. But thanks to the knowledge over the years of filling trash cans a master craftman craft will emerge. As experience is out best teacher & you possess a fine skill set, so keep going. Out of trash a master can be obtained & I don't think there's any other way to get there as a craftsman.
I thermocycle my blades at least 3 times before I quench. When I checked the grain on a test peice the grain was so fine it was amazing. Not trying to sound like I'm bragging.
I seen videos how people make slip joints and they temper the back spring until the center of the spring is purple or blue and both ends of the spring untouched only with a light straw color temper that way it has a springiness to it I think you should try again
@@Gabrulo_knifemaking and I also think it can depend on what certain metals you can use for the back spring but I'm not 100% certain on that. but I've seen people use circular saw blades to make slip joint knives and they work pretty fine and their springy and it 1095 steel is as good or 15N20
Yes and no, he clearly had some ht problems (as he correctly assessed, that grain is bad). When properly done, you can spring temper the whole backspring no problem. Assuming the steel was normalised (as it was flat stock) the quench was wrong (too hot or too much time at critical temp)
thanks! it was due to too much heat in the heat treatment, c70 steel must be quenched at around 800°C while i quenched at 1200°C and that caused the grain to grows and weakening the structure
That's really sad... But since you had a heat treat issue on the first blade, I'd assume the spring has been overheated too.. so if I was you, I'd have re-heat treated it with the other blade, and made a high temper on it. Don't get discouraged, you know how to do this find of knife, you just have to work on your heat treat 😉
Thank you so much for sharing this. Now I feel a lot better seeing this also happens to a pro like you... I am currently still in a stage where I mess up more projects than I actually get to work - and that with the "easier" fixed blades since until now I never dared even trying a folder. You really gave me back some motivation with that video :D
Dentre erros e acertos . Sempre um aprendizado . Parabéns por compartilhar, admiro seu trabalho . Mas fazer normalização nos metais por 3 vezes seria seguro. Com o auxílio de um imã. 👏👏👏👏 . Ótimo vídeo..... Há fazer a mola de sustentação de 5160. Pois o corpo de Inox muito duro e não pega imã. Kkk
Was going to be a lovely blade....thou I'd probably dismantled it & salvaged anything I could to replace what I had to ...too much time invested to end with nothing to show but a video...lol
I thought to salvage something but having glued and pinned the scales to the spring i would have destroyed the materials so the only thing to do was throw everything in the bin
Не расстраивайся, я тебя очень понимаю, но работа была сделана достойная, да зерно крупное с термичкой накосячил маленько но без ошибок не одно хорошее дело не бывает
Дружище, за любезно предоставленные чертежи, объявляю человеческую благодарность!
don't give up... please try again... i'm sure we all want to see it. 👍🏻👍🏻👍🏻
Brave of u to show this! It takes balls to admit u r not perfect! Honesty, love it. U got my respect! Now gimme a succes😉 project!
Sad. You are the best bro.

I really appreciate your words, this is why the knifemaking community is the best, we support each other without stupid jealousy, thank you

You are right no worries, i overheated the blade, next blades i made i turned down the gas pressure and the steel reacted much better
I seen videos how people make slip joints and they temper the back spring until the center of the spring is purple or blue and both ends of the spring untouched only with a light straw color temper that way it has a springiness to it
I think you should try again
Thanks for the info! I didn't know that, maybe i will try again 👍

Yeah it certainly is important the type of steel for the spring, shouldn't be too hard, i have other projects now, in future i will try again for sure

@@gabrielemagnabosco8926 everybody can't possibly know everything. but you made a good statement. I approve
Every failure is an opportunity for learning. And...after all...it is just a knife. Best of luck with future endeavors.
O Man That hurt me!
Very sorry for your loss.
Do you know how it happened?/or what caused it to break?!?!
thanks! it was due to too much heat in the heat treatment, c70 steel must be quenched at around 800°C while i quenched at 1200°C and that caused the grain to grows and weakening the structure

The only failure was not to temper the spring sufficiently. Pry out the pins and make another spring and replace the spring. . Dont give up!
Sorry to see that happen, its heart breaking.

Damn! It was beautiful too!
Olá amigo
Por favor, passe esse modelo para mim?
Achei ele muito lindo.
na descrição você pode baixar o pdf do modelo para imprimir
@@Gabrulo_knifemaking obrigado amigo
Vou fazer as talas em aço 1075 e lâmina e mola 5160.
😁😁😁
It's so beautiful!
Thanks! Unfortunately it didn't want to work 😅
it's so shame for all the hard work put on it

What kind of steel u usefor the blade?
It was c70, a basic carbon steel
Excelente trabajo, está genial
Please put the Arabic translation. I am a good follower of you and benefited from you very much ... Thank you, always with success and success.
I'll try to find a way to do it thank you
lost but won!
It happens..
buonanotte gabruloo
Buonanottole
non tutte le ciambelle escono con il buco 🤣😁😂... io la molla la tempro solo nella parte apicale giusto xche non si mangi nell'aprire/chiudere
In realta basterebbe fare il rinvenimento alla molla due volte...
Try welding
درود. خسته نباشی من از ایران کانالت را دنبال میکنم. ممنون
