So i got up today and said, lets melt some copper.
I use a leaf blower to fuel my charcoal foundry, the original one used an old broken hair drier, but it only got up to aluminum temperatures. This one is a notch up the scale. the leaf blower was bought for 30 euros at Leroy Merlin any leaf blower will do, then it was connected thanks to all mighty tape to a tube that leads into the heart of my furnace.
The furnace was made in under a day, i went to the junk yard and got for free a old empty tub of paint, filled it up with some refractory bricks. then filled in the gaps with any old dirt. The lid as you can see was just a floor tile.
