NZ Steel mine black sand from the North Island West Coast at Waikato Heads and then use it to make steel products. Further South on the same coast at Tahoroa it is mined and and pumped as a slurry to a pick up buoy where ships load it for transport to Japan etc.

Leaded tin bronze is the most yellow

Metal working is so beautiful

Now it makes sense! my mom had this “beach”-saying: “Once you go black, you will never go back”. She is right afterall! Black is much harder, tougher, and can withstand a multi-hour “warm-up” - and still keep on hammering and smashing the bloom! For hours!!

You promised me you would be back soon! Why are you not back?

I really like the way you presented the information about this build. I want to make an electric aluminum smelting furnace along the lines you have made. I wanted to make my furnace capable of just pouring the molten aluminum directly into an ingot mold or a casting jig. Ideas? Thanks, Dave.

Is there blue print of material and design of wiring

Thank you for the video and answers in the comments

couldnt you just take a few cook range 240v heater elements and save yourself all the calculations and cost , these can be found anywhere , thx for sharing ! nice job !!

Dear sir Would you please send me a file with measurements of hinge between bottom and top of the kiln

Tusind tak for videoserien! Den har været uvurderlig til at foretaget DIY reparationer af keramik-ovne!

Таким же способом пробовали железную руду делать из золы. Рабочая схема.

Just want to add that I really am enjoying this tutorial series. Well done!

would ceramic fiber insulation blanket protect your control box?

He is playing Minecraft java edition in real life brah

Can you tell us why is a thin wire gauge not recommended?

That’s pure iron ?🎉

Also I want to add he engineered this kiln very well.

This guy is really smart and good with his electrical. Awesome video! Thanks!

I love clever can-do people like these guys!

Does anyone know where can I find an iron foundry that could make a cast iron cauldron??

OMG!! Thank you for letting this video come into my life!! How much the whole instalation cost you?

Hi Jakob, I would like to know where you got the coil maker or spring maker? Thank you Great job on the kiln

Finally now i can make a newtron gun

Ever done in Denmark???

Can you explain how to wire this setup but using single phase 208/240v?? I’m moderately confident that I have the wiring correct but your validation would be great! I am using a 14/2 SWOOJ cable for the power supply. I will be grounding the components to the electrical component structure and drum as well. I’m also using a GFCI Breaker on its own circuit to power this unit.

And NOW - after 3 and a half video, You tell me this is a 3-phase...🤕

Do you know what cause the kiln to power fail?

melts at ray bradbury's fahrenheit 451 (actually a couple degrees less)

I love this beautiful chandelier, Jakob - thank you! Have you created plans anywhere that I could follow, as I'd love to learn more about PCBs, and am only just getting started with 3-D printing so have a lot to learn... 😊

Many, many thanks. You left me (helped a lot). I have a lathe, but I didn't know how to wind Kanthal wire 1.6mm. I needed 277 threads and then a gap of 3 mm between the threads. It didn't work on the lathe. You showed me the video. Thanks thanks.

I think the iron got hardened and more brittle after quenching, you should probably temper it before cutting

can I have your contact number please.

I hope you continue this project, and thank you for sharing even the pitfalls and failures with everyone. A "how NOT to" guide can be every bit as useful as a "how to" guide!

What is heat resistant cement ???? I got confusion

Infinite money glitch thanks man. I'm gonna look for resources in my area

Did you write up the Design Requirements in LaTeX solely for this video? Respect.

I was all in ready to get my nephew to help me building this kiln based on Part 1…. until the power design requirements. I’m too scared now 😂. Excellent video though

I see you don't have thermal insulation other than the firebricks. Is it enough? What temperature do you measure on the outside of the barrel, when inside it is 1300 degrees Celsius?

How much time will taken melting iron bro

Beautiful, I’ve just cast a silver ring for the first time, I didn’t have enough to make it all the way round so I’ve made a smaller design and plan to recast it soon

How much bloom from the 70 kg ore ?I can't grasp it ...

Did you end up finishing this project?

Its been 3yr since the smelt ... have you finished consolidating the rest of the bloom yet, and made anything with it ?

I thought best practice was to mix limestone with the iron sand to assist slag formation and runoff ? BTW your plinth probably should have been underlaid by 4 small I beans ... it wouldnt have tilted the way it did when you harvested the bloom (6:50).

Where’s part 5 here?

How do you control the ramp in order to not heat too quickly?

great video!

Oh I see it was a success when I saw the lump.
