I called a local tire shop today and he said they probably have about two 5 gallon buckets of wheel weights that I can buy, hopefully reasonably. I want to melt and flux them and form ingots. What is something inexpensive that I can use to get started? I have heard muffin pans, but is there a special type? Other suggestions? I am on a limited budget, especially until retirement check comes at the end of the month.
