Drew up some plans in AutoCad the last couple of days so as to get some ideas on building a melting pot. I then put them into a PDF file and hope that you will be able to view them. They are very preliminary and just thrown together to get the brain thinking. Here are the links, I hope they work and that someone will get some ideas from them. There are two similar but different plans, also you will have to turn the drawings to read them better.
Hope this works. I had them in the wrong folder
