Thanks Frosty for the Reply. I want to cast stuff I am an Artist and need to smelt aluminum yes it's a You Tube job and was a test, hence the dry brick layout I have all that is needed to construct it. There is a lid and it was used today to have another go ( wont put up today,s video now on how to blow a hole in a thick stainless steel fry pot..) the depth will be at the steel can top just did not want to cut bricks at this point. The torch is from a down draft kilm 2m3. Today I put the pot on 2 sections of steel spring to mount it above the torch entry and there was just 1 inch clearance around both pots, I had been thinking I was to close to the walls..Oh and today I ran at 5 psi. I made the steel pipe yesterday with the required holes for lifting and a section of the base had an extension to use the 3rd rod to pour and had formed a spout as well. I have no idea as to how to tell the pour point temp of aluminum for casting I thought about putting an add in the local paper for anyone who knew about casting as the only place around that did Non Ferris closed a few years back. I will change (edit) header re address, thankyou
