I'm working on putting together a swappable charcoal to electric heat conversion for my smoker. And am wondering about how best to control the element I have for it. I'm using a 110v 1500w electric burner I scavenged out of an electric BBQ that takes the smoker up to high. 300 deg F if left alone. I was thinking it would be best to set it up like an electric hotplate which uses a Potentiometer (right?) Can one of you tell me is that the correct part (a pot) and some advice as to what sort of voltage/wattage/amperage ratings I should be looking for to keep from burning the thing up. I'm hoping this is a radio shack part since one's around the corner from me but if I knew what I was looking for I suppose I could order one or find one somewhere in town as well. Thanks-Max
