2 weeks ago i had a council clean up and i finally cleared out the shed almost everything went out i chucked out 4 cylinder and a 3 cylinder aluminium engine blocks, cylinder heads, crankcases, aluminium clutches, starter motors the lot was all thrown out because its value is only around 50c $1 a kilo i just didnt really care about it now 2 weeks later i buy a lathe and realise youtube is flooded with diy furnaces bugger!

i want to know is there a safe way of making a furnace? All these diy videos on youtube are just about killing your lungs, u cant breeth the dust from fire bricks, you cant breeth in perlite dust, the white fiberous mate causes lung cancer breething in plaster in paris effects your health

Is there a easy and safe way to build a furnace without harming your health?

I still have some 50x50x1.5 alloy tubing i have around 4 meters of left over 100mm i beam i would love to melt it all down for the lathe

As with most things, its all about the dosage - Unless yer doing the smelting on an industrial scale I can't see there'd be much to worry about. For starters, stand upwind..:cool:

YBAF Just seems like anything diy furnaces is trying to harm your health there is one video i found by a Aussie using a flower pot albeit simple it worked for him so i am going to try it but i may wrap the pot with steel mesh so if the pot cracks it will be held together

About 5-6 years ago i bought a Crompton lpg torch from ebay it's an aggressive little bugger should work perfect for around 500mls 750mls a pour

And drilling a hole in a clay pot cannot kill u i dont think lol so its pretty simple idea

You had better stop using your welder and lathe too because they can harm your health too.

Before working with the materials you intend to use you should read the MSDS.

A respirator/dust mask, face shield and gloves should provide the protection you need.

Never underestimate the hazards associated with molten aluminium.

I'm a lot more careful after a near miss.

Yeah as with anything melting at 660c there are always precautions to take i was going to do it in my front yard as i have rowdy pets that love to bolt around and plough thru anything in there way typical american staffies

There’s a men’s shed in Sydney that has/had the gear for casting Al.
Here’s the minimum safety gear you need plus the knowledge on how to use it.

That is a pretty big set up look at the size of furnace they are using plus 2 blokes 2 propane tanks

I'm looking around might go induction heating but still seeing what is out there, def cannot go coals due to the ambers
