Making a Aluminium Casting Foundry for melting aluminium (Aluminum for the US) out of a 13kg propane gas bottle

why am I making an instructable that many people have already done? well I thought it was an amazing Idea but I feel there was some room for better documentation, and a few little changes such as a lifting mechanism for the lid and no fire cement for the refractory.
