Aluminium Cylinder head melted in a Mega crusible.wmv

This was a bit of an experiment. I was finding it very difficult to break up the aluminium cylinder heads from old motor car engines to fit in a normal crucible so decided to melt the cylinder head in a mega crucible made out of stainless steel I use this type of aluminium in the foundry as this is the best grade of aluminium to cast with, thats why engine manufacturers use it to cast in the first place, sure you can melt all different grades of aluminium in the foundry but its not that good for casting if you want good results. So i was wondering how long it would take to melt a complete cylinder head, seeing as i never had a top section to put on the furnace to retain the excess heat, I was guessing it may be a couple of hrs as most of the heat was escaping out the top of the foundry I have had lots of questions as to what i am going to do with the aluminium once melted. No, I'm not selling it for scrap etc, one day in the future i am going to cast grave headstone plaques for ancestors with head stones So if anybody knows of a page or site the shows' how they are made, that would be great, link me add me or direct me. Thumbs up and thanks for watchin
