Re: Re: Melting Aluminium at home

[Bodul666]

It would be VERY good if you put the instructions on the description, like the specific details about the things you used(so they don't need to ask every time) . And, for example, i didn't understand nothing from 1:43 onward.

[jaytank31]

what were the electronics just plug it in the wall?

[mvpvlad]

pm me the answer what kind of pot is in the middle

[ElPaso7708]

Hello

I want to make this device. Can you speak for me, how much energy should be added? Or what time still fuse?

Thanks

[insanezy]

i would have just used sand instead of furnace cement that way you could lift out the crucible to pour with

[TheMacason]

Press five for nails XD

[Truthhurts3pm]

Alright I now have everything I need, just drilled the holes in my flower pot for the heating element to go through. Now my question is would it be alright if I made the chimney cement mix snug around the steel crucible but not to tight. So I would be able to pull the crucible full of melted aluminum out of the flower pot to pour. Would that be possible? Would it still create enough heat?

[blitckrieg]

how many degries ?

[yagomtv]

Hey, I was wandering, what kind of material is that at 0:18, it's normal baked ceramic?

[Truthhurts3pm]

What is the item called that the heating element is wrapped around?Where might i purchase one at? I found everything else at Lowes except for the chemney sweep cement but I got that at a local supplies store. Please respond.

[Pablo4i]

where did you buy the cooking element?

[Truthhurts3pm]

@Pablo4i Lowes...$25 for 8'' with 5 rings

[DELRICO213]

good job i really like what you have made and thank you so much for sharing.

[neverneen]

This uses induction heating, correct?

[cassiavc]

@neverneen Nop. Uses joule heating. It is the away to transform eletrical energy into thermal energy.

[cassiavc]

Can I do it without using the ceramic jar? Just using the calrod and the porcelain cup?

[dreasim]

dude! thank you so much. Brilliant design and clear simple instructions. I'm so excited to try this.

[Rammmathornnn]

very interesting video. Wanted to cast aluminum for quite some time.

[coffeecupblue]

This is 220? Can you melt aluminum with 110?

[gregduffy72]

i love how clean that is, beats the burning of charcoal and all that mess, good job!

[gregduffy72]

I love how clean that is. good job, will have to try that!

[TheKyla1981]

thanks

[TheCombineify]

Nice

[gus23a]

how much power does it need and what powersource are you using?

[osm3u]

I think the molten aluminum will damage the heating coil if placed inside the ceramic pot. This is great information. Thank you for posting.

[plavins1]

hey please reply!!!!! i have an old 2KW washing machine heater and when i turn it on it glows red hot not red but yellowish. so could i use that for my aluminum melter?

[ninja6kid]

go buy a 20$ IR laser thermometer

[chinnosequeira]

guys can i just ask what yuo use the perlite for? what is it mixed with the cement for? thanks a lot for your time....!

ps: greeat video

[obeyance]

@chinnosequeira From my experience with perlite, its just to take up space and make air pockets. If you dont know what perlite is, its used in horticulture to make potting soil less dence and allow more water to drain. The cement is a special kind that allows for way higher temp then normal cement which could have air holes, super heat and explode like a cinder block. Maybe the perlite makes it have less of a chance to explode while still taking up volume?

[pietzeekoe]

how did you solve the problem that when the coil heats up the resistance becomes les thus making the coil hotter intil it melts a steel crusible or itself?

[damianduff666]

Does the wire to the element not get hot , and would i need a certain core thickness wire to the plug if it does

Cheers

[BITTYBOY121]

I like this idea of your furnace very much, but the only thing i'm not 100% keen on is the clay pot you've used (no offence)...I was wondering would this setup work using a large (5kg size) graphite crucible and coiling the cooker ring element around it the same way?? - An opinion / answer would be greatly appreciated - Thanks.

[rbneville]

i did some calculations for people saying running this would be expensive due to electrical costs. If you run a 1200 watt element for 8 hours a day for 30 days (assuming your kwh price is 0.12) you only spend $8.64

[johnnyzigzag2]

great stuff!! How long does it take to get up to temperature?

[snooffun]

How much did this cost to make?

[LancerFIN]

Less than 50 bucks. He said that in different video

[snooffun]

Thanks.

[ToddWalther]

Oh my! Thank you very much! I didn't even think of it!

[robotpredator8]

hey what kind of bowl is that clay?and the furnance cement where can i get one of that?

[dannybuntu]

this is awesome.

[masew49]

yu suck

[TehMG]

I did something like this once, only I made a crucible out of steel and the heat source was an oxy-acetylene torch. It worked rather well.

[Axel2989]

check your element book or google is your friend

[andres9147]

at what temperature does aluminium melt at?

[vinee94yo]

What did you use to change the shape of the isolated heater.

[vinee94yo]

Do you think it would be able to be used without the crucible in the middle of the concrete with the heating element suspended in the cement and smoothed on the inside, which is formed by a depression made by a container.

[GreatNorthWeb]

The voltage/electrical supply question seems to be unanswered. Where do the wires lead? Do you basically just plug that thing into 110vac, or is there some other device regulating the electrical feed? Any help clarifying this detail will be most appreciated. Thanks, GNW

[olawlor]

A CalRod heating element is electrically just a resistor, so you can indeed plug both terminals straight into 110vac wall voltage, or use an "infinite switch" dial. At a known voltage (V) and resistance (R), you can figure out how many amps (I) it will take from Ohm's Law: V = IR. My elements are usually 2-5 ohms. The same element will also run at 220vac, though it will consumes four times as much power (both V and I double). Use GFCI--electricity is especially dangerous around molten metal!

[curioz29]

im in australia so not 100% but i assume that the elements would have a rating ,over here around 2400watts at 240 v , which wouldnt require any thing other than a plug .if the element pulled too much current  it would only blow a fuse though

[bcfilename]

220 or 110? and what is the amperage?

[jupiterlight]

nice.but your nail is so dirty

[zezimashock]

i didn't know just a question i had.

:D

and yes i know i maybe had to searche wiki first :S

[maliluki]

cut your nails.... really

[zezimashock]

can you melt copper with that?

[vinee94yo]

Aluminum and copper are separated by a few hundred degrees in their melting point. this means that you would most likely need some source of external heat added to the metal.

[fizzgig656]

hi, is there any reason you used the element outisde the ceramic pot rather than inside. i would have though direct contact would be better?

[pass135]

I think, due to his last design having melted the element i assume it was too close to the Al perhaps idk.

[curioz29]

another reason could have been that the element's internal wire could have been damaged (moved towards the outer side) when it was being moulded around the ceramic bowl.

the elements are a wire surounded by an insulating compound tubed in copper .hot spots develop if the inner wire gets too close to the outer tube

[rbneville]

@fizzgig656 if the molten metal touches the element it will bridge the electrical circut causing a short circuit. I think

[sooperdude1992]

@rbneville no .. thats totally incorrect. your an idiot

[rbneville]

@sooperdude1992 sorry i was tired when i did that math but it still wouldn't be to much.

[RazedByWolvs]

@rbneville If your metal pan touches the element on your stove what happens?

[plavins1]

@fizzgig656

i did it and the hearer burned out after an hour

[StickyAnus]

cut your nails

[dedeye1]

@StickyAnus With a name like StickyAnus your concerned about the length of this guys fingernails? Odd.

[LEBANON707]

Very instructive Step by step demonstration

[frigerisampa]

@LEBANON707

Yes is good...Sim e muito bom quem quiser desta resistencia de 1500watts eu tenho.

[BasementBen]

Thank you very much, these 2 videos are the very best I have seen on home furnace. Great job!

Ben.

[Sharker2468]

how much electricity did u put throught the coil.

[jasperash]

so the crucible is fixed in there, maybe you should have made one with something just to fill the void of the crucible, then removed that once the cement hardened. seems like a great build! oh yes is it just 110 vac? 2 live terminals from an electrical outlet?

[carlamyjohnson]

hi does anyone know what the inner pot was made from? and what would the pot that went insid the inner pot be made from(the pot that the metal goes directly in)?

[goodtime444]

what is the wire that you connect the heating element to?

[zloisop]

is melting pot made from ceramic? Are you had try to melt bronze?

[pitbike2006]

how do i wire up one of thease do i just put + and - on each end or something anybody help

[mannys9130]

you want to take out the element like he did and do everything he did, just remember which terminal went into which spet and attach them with wires back to the hotplate. use the hotplate to control temperature.

[navycook1981]

written directions, im trying to figure out the proper temp to melt lead and aluminum anyone know?

[JonSpink]

leads about 440 centigrade aluminiums about 670 or there abouts if this thing can melt aluminium im really impressed.

[ivanov3000mltk]

Very nice video. Don't you find that bottom of inner crucible should be heated too? May be small part of heater should be placed under the bottom?

[TheFriendlyMeek]

Interesting video(should have thrown in some music tho). I was wondering what you used to make that.

[boyprodegy]

Interesting!
