Great demonstration - your power hammer would greatly appreciate it if you took smaller bites of steel when drawing out. Full face blows should only be used for flattening and initial setting of a weld. It's very inefficient to draw out steel with full face forging. Try slowly feeding in the steel forging one or two blows on a 2-3cm section of the bar then feed it in another 2cm and repeat so you take bites all the way down the bar. When you get to the end, run the bar backwards taking full face blows to flatten out any steps that remain. I hope this helps! Cheers! - Jens
I have some ideas for videos. But today I don't have to much free time, because i have 8 months old daughter. I would like to make one video till end of this year :-)
Nice! How can I be sure to obtain steel and not something with more or less the same carbon content than what has been put in the forge? It's hard to carburize... Also didn't you lose a lot of carbon during the cleaning process? At the end it seems that it's not full of carbon
The amount of carbon is affected by the fraction of the input material.The smaller fraction, the more carbon the resulting steel has. Another parameter affecting the amount of carbon is the height of the furnace. The higher furnance, the more carbon the resulting steel has. You have to try what will ideal for your needs. You can estimate the amount of carbon by spark test or you can try if its posible to hardened or not.
If you left it in the furnace longer, would it absorb more carbon? I’m thinking the taller furnace will extend the time it’s in as it flows down. Great video. I am working towards this.
Have you ever made a fire steel from wrought iron or a bloom? Getting a high carbon input to make one in a clay and bellows forge outside is proving difficult. I've made carbon steel from wrought iron and it throws sparks but it's not high carbon like an old file. I've tried clay pack carburizing for over one hour and also leaving the metal below the toyeur air input in the carburizing bloom zone for a half hour period. Both methods added carbon but not lots as hoped for. Any help would be appreciated. Thanks.
Yes I have made fire steel from iron bloom made directly from iron ore you can see in this link (ruclips.net/video/u0YsdS9DYuQ/видео.html). During Iron smelting, there are many variables that affect the amount of carbon in final steel. Such as height of furnace (higher=more carbon), air bellows volume and pressure(higher, bigger=more carbon), fraction of iron ore (the finer fraction = more carbon), ratio iron ore/charcoal (more charcoal= more carbon) slag tapping frequency (slag cover iron bloom and prevents carburization of iron bloom).If you want to use carburization in forge as in my video, you try to use higher forge, higher pressure of blower, try use smaller pieces of input iron to maximize the surface. I hope my advice will be useful to you.
I'm gonna try this but I'm going to do it with the shredded up body parts of an old impala I have a horribly rusted, untitled, and wrecked 1966 impala that I got for free and I think it's metal isn't galvanized
It flux for easier welding, exactly Sodium Tetraborate ( Na2 B4 O7). Loess or silica sand or grass ash was used in the Middle Ages, but when you use Sodium Tetraborate its easier because it have lower melting point.
You just demonstrated why iron was so expensive before the industrial revolution. Good show!

That's one hell of a power hammer you got!
Great stuff man, that was awesome! 🇨🇦
Thanks
Will love to see more vids please! Just subscribed!

2kg (66%) lost from refined bloom to homogenised bar? Is that all as hammerscale during forging?
Yes, exactly.
curious to see what you made with the steel, I guess a nice sword or knife. love these channels, sad that you only made 1 video
Does this process add enough carbon to make a knife with?
Yes, the steel is hardenable.
Thx

Thanks Josef I will for sure check that video out.

👍👍👍👍👍👍👍
Would it work to somehow mix my mother-in-law into the low-grade steel before melting it, and burning it off?
I am not sure, I have never try it. So you should try it and share result of this experiment. I think this additive will spoil the whole process.
How much time did it take to "cook" this?
Approx 2 hours for making bloomery and 2 hours for blacksmiths welding.

Enjoyed a lot
Fantastic blacksmithporn
