Hello from France

Interesting... I am building a propane one capable of handling approx 6kg. Did you design yours yourself or base it on someone elses design? Would be interested in the running costs, what current draw?

It's my design :^)
For hobby foundry, if you stay on aluminium, electric is the best for health, security, quality and running cost.
this one was my first design with 3,2Kw power on 230V and can melt 5kg in less than 1H at about 40 cents cost here (11 cents €/kwh)
He was designed cheap but can melt alu at 800°C for a long time with no problem.

if you want to go to bronze (1150°C) propane will be way faster but still higher cost and less melted product quality.

I'm designing an improved version with 4kW and better insultation to catch easily bronze melting .
...i also have a rated 40Kw gasoil burner to try cast iron :^) but not the same race here.

I think i would like to have this in a build thread, seems a good way to cut down the chip volume at least.:lol:
