Got a Big Dipper lead furnace , did not get hot enough , sent it back ,they just sent another one, not hot enough to cast , just a side note , FedEx dropped it off and the box was ripped open . careless packing on Lyman , The furnace was put in one corner with no cushion . I have a friends Lee 4 pound furnace no problem. Lyman , if you want to have this junk made in China , so be it . 75 dollars now and no results , sorry I am done with you'all !!!.. And FedEx , You ain't worth a damn ..
