I have been melting ww's down into ingots and casting the bullets in my garage with a 20" fan blowing the fumes out the walk through door. For this I've been using both the Coleman stove and a 10# Lee electric pot. I'm now thinking of using the electric pot in my basement with pretty much the same ventilation to cast bullets and doing the ww meltdowns either as I was or outside. The basement is much more comfortable to work in in the winter. What do the rest of you do? Thanks for insight into a good safe setup.
