After a long bout of "Who can make the best chiminea" between a friend and myself, I finally came up wth the washing machine drum idea. I soon found an old broken machine and went to work removing the drum.
I was unable to get all of the elements off so the first trial burn had to commence with the machines aluminum drive pulley still attached to the drum. During this burn I noted that the aluminum melted with the heat of the chiminea, and so, the washing machine foundry was born.
Below are some pictures of the results:
