The blower is in turn powered by a car battery with a dead cell, charged from a 5W solar panel strapped to the awning. I just drilled 4mm holes into the battery terminals and use 4mm banana plugs for everything. As a bonus, I can plug in a LED spotlight which lights up my nocturnal smithing activities.
The flowerpot used as the forge's firebowl has fragmented, but it was far too deep anyway. Time to spend another few bucks at the garden centre and get a more bowl-like flowerpot. But we're back working metal again, and this makes Winters bearable for me!
I hope to cast bronze in plaster moulds made from RepRap'd cores, but for this test we just cast it into a crude charcoal mould.
