How to Make an Electric Foundry For Metal Casting – Part 1

In this video I am going to be showing you how to make a metal melting foundry that can melt aluminium in under 20 minuets!
This project is probably one of my more dangerous ones combining both extreme temperatures and lethal voltages and all safety precautions should be taken and always wear enough personal safety gear. This project could easily kill you!

The video where I upgrade this foundry with a PID temperature controller and many other good thigs is now up!

Part 3 upgrades video is now up as well:

  1. u cud probably add a stepdown transformer, bring down the voltage and use the increased amperage to heat a longer coil.. this means more even heating throughout the length of the furnace, and also, less chance of getting elecrocuted. after all, voltage is actually the thing that "electrocutes"..

  2. why would you die from touching 220 volts heating coil? hurts like hell but dying? not so fast. europe runs on 220 volts as standard and not much people die from getting zapped with 220V

  3. what's the hottest temperature feasible with this kind of design? ie. what's the hottest substance we could feasibly melt with such a relatively environmentally friendly method?

    Could this be scaled up to be used for small-scale recycling projects?

  4. i touch a 110v about 3 seconds and im alive… i couldnt let go the cable. 220v you have a worse chock but you automaticaly will be pushed out.

  5. 44 GB and over 300 clips. I underestimate how much work some people put into their videos, those 18 minutes just flew by. Must've been the editing, well done.

  6. All pretty much amazing…Up to the point where you admit that you can actually just die out of electrocution :/

  7. Minor correction: That plug is approved for 250V, but the UK grid is actually running on 230V. This means your heating element is actually 1.6 kW. Still powerful, though!

  8. maybe add an isolation transformer so there is no risk of shock.
    the galvanic isolation would mean there is no potential to ground so you would have to touch both poles at the same time to get a shock.

    sure an isolation transformer at 1.8kW would be expensive, but worth a look in future builds.

    great job, very interesting.

  9. How many Kilowatts will this foundry need if ud power it for 15 minutes?

    Approx number also okay

    In Germany Kilowatts are around 0,25€ thus it might be quite expensive to use this foundry design.

  10. One of the few people that when explaining the costs doesn't forget that it took not just money for materials, but time, resources and overhead to build and run it

  11. is the wire isolated? Because you are using unisolated pliers when you touch the curucible when it is 1cm away from a 230V wire.

    That looks seriously dangerous to me.

  12. you can youse a wood saw miter saw Skilsaw for cutting aily but I have a cutting disk on a grinder

  13. Great vid mate i'm definitely going to make one. Find a local scrap metal yard and see if they will resale. I get all sorts of awesome steel and parts for my projects at a very low price.
