hello, I have been casting for a while, using a bottom pour lee casting pot, and was given a pretty good amount of lead in the form of 2.5" balls, from a deceased reloader. These balls will NOT fit in the pot because of the bottom pour mechanism, and i dont really want to try to work around it. So if anyone has this: http://www.midwayusa.com/product/476462/lee-melter-furnace-110-volt?cm_vc=S014, could you tell me about what the internal diameter is for the pot? The amount of lead i recieved does not justify buying anything more expensive than this, so im not open to the idea of upgrading. Nowhere can i find a firm inside diameter, so anyone who has one let me know, thanks
