I use a $5 electric hotplate from Walgreens for the heat source, and a 1.5 or 2 quart stainless steel saucepan. Melt the scrap, stir in a handful of sawdust, scoop out the ash, and ladle the clean lead into little stainless steel condiment cups. (I can pick up the saucepan and pour the last ingot)
The 2.5 or 3 ounce cups make a nice sized ingot. They don't stack all that well, but you can put a lot of them in a bucket.
