Is there any place where you can buy a lead furnace (melter) in the Ocean co area?

I would try a plumbing supply house, like Ferguson?

have you tried ebay 

I'm a plumber, I use my old lead pot it works great. Supply houses don't really sell them anymore. They may be able to order one. I have a bunch of different sized crucible's if you have an outdoor turkey cooker the burner will work just as good as the actual lead pot burner. I will give you one if you want. I'm pretty sure I can get away with owning one pot the rest of my career instead of 10. It's pretty rare for me to need to pour a lead joint anymore. There's way better ways to install cast iron pipe these days.
