The design is wonderful. I learned a few new materials. Great use of electricity; I was going to run 240v but I think 2x 120v is smarter. Please consider using proper tools and avoid setting crucibles on concrete; it could explode! I like your design the most from what I've seen and will emulate it with a much larger build!

It is a 100v / 600W resistor, so about 16.67 ohms.

Hola, buen trabajo con el horno electrico, por favor permitame darle una recomendación, no use ningun tipo de madera cerca del horno, se maneja alta temperaturas y resulta un peligro, cualquier pequeño escape de aluminio fundido provocaría un incendio. Un Saludo.

Apart from not clocking the screws... Sweet!

@7chome_seisakusyo 8 ай бұрын

It took me a week to figure out what the word "clocking" meant! I also learned that the people who align the screw heads are called "screwcrockers". Actually, this is an agenda I have been very interested in for a long time. Thanks for providing a great agenda! As an Industrial designer, my opinion is "I would like to CLOCKED it if possible". However, as a Mechanical engineer, my opinion is "Should not be CLOCKED". Screws should be tightened to the proper torque, in which case the thread angles cannot be matched. So when I see these neatly "clocked" screws, it looks like they were assembled at the expense of performance. As an example, I don't like the Royal Oak by Audemars Piguet. Well, I don't have the money to buy one... I really enjoy our conversations about this! I'll try to figure out how to clock the screws with the right torque. Someday I hope to join the ranks of screwclockers!

I finally got bit by the metal melt bug and want to get into this new hobbie. Im looking it maybe a DIY version but which is better or cost saving, as far as spening money on gas vs electric? Also which melts faster gas or electric? Thanks for any advice and info keep up AMAZING vids!!!

@7chome_seisakusyo 8 ай бұрын

Hello! Thanks for watching! Welcome to the world of homemade metal melting! I live in a small residential area, so using a gas or other fire is a bit difficult, so I built an electric furnace. If your place is large and gas is easily available, I would prefer to make it with gas. I would also build a gas furnace if I could. I wish you success and enjoyment!

@muebledurable8270 9 ай бұрын

hello, to melt aluminum faster, can i use a steel crucible and with the wires more closer or attached to the crucible? which transmits temperature better, a sand crucible or a metal crucible?

@7chome_seisakusyo 8 ай бұрын

Thanks for the comment! My crucible is made of graphite. Both iron and graphite are conductors, so it is dangerous to put the wire too close to the crucible. If you want to melt faster, you may want to increase the power or improve the heat retention.

If I am not mistaken, the hand mixed heat resistant cement is called refractory. Great build! I thought when you hand made the lid / top and matching plug, it had to be initially fired (no metal to melt), then it was ready for use with metal. Did you make the crucible too? Thank you 🤓

@7chome_seisakusyo 9 ай бұрын

Thanks for the comment! The cement I used is fireproof. Quenching is not necessary, but I did it just in case. I didn't add reinforcing steel bars to the lid I made in the video, so it cracked after a few uses. So I rebuilt it after this with reinforcing steel bars. The crucible was bought from amazon. Please check out my other videos!
