Scavenging copper from 7 old transformers

Collecting copper and aluminium from old transformers. I got a heap from an acquaintance. Hard work, but it all adds up in the end. I'm selling my furnace. Can't find the right fittings to make it work. It's probably for another country. I've should have bought the more expensive one from the start instead of trying to save some money on it. Oh well.. It takes longer but i will be smelting. Just a matter of time.
