I use a Lee bottom pour pot IV. It will drip, but mine stops if I tap the plunger with the handle of a screwdriver. If it continuals to drip the pot needs to be cleaned. For fluxing the lead Frankford Cleancast is the best I've found; it will smoke; but will not flame. Also spray you molds with Frankford Casting Release before using the. (Some people just smoke them with a candle, but I like the release spray) Now for the big tip, get a Do-it catalog and turn to page 86, everything I mentioned is on these two pages, for sale by Do-it. And if you have any questions about any of these products.. just call Do-it!
