I'm getting into casting and about to order the equipments. I do have some questions before taking the plunge: 1) Furnace - Lee 20lb pot with bottom pour. Question is, 110v or 220v? 2) Molds - Lee 2-cavity. Question is, on the Midway web site, some Lee molds are listed as tumble lube and some aren't. I want to tumble lube, but I like the non-listed tumble lube designs better. Can I tumble lube the non-listed as tumble lube bullets? 3) Lube and sizing - Lee Alox lube. Question is, is it necessary to size the casted bullets? From the reviews I read regarding the Lee molds, it seems like the bullets are true to size and sizing isn't needed. 4) Flux - What do I use to flux? 5) Lead - Assuming I will be using tire weights from many different sources. How do I determine the hardness of the final product? 6) How the do you convince your significant other to let you cause a huge mess on her (mine ) yard?
