You get you a small hotplate from Walgreens and you will NOT be disappointed. It changed how I cast completely. I seriously set the mold on the plate and turn it on HI when I turn on my Lee pot. BY the time the pot is ready that mold is beggin for some lead to be poured in it. And other than thinking I may be running my lead a tad too high, I cast keepers from the very first pour. Even with my Mihec molds.
For the record I use an old circular saw blade on the hotplate as my surface to rest the molds on. The handle pivot bolt props perfectly on the tip of the blade and holds the molds flat on the surface. I will get a pic for ya when I get home.
