I have made myself a mission to build a furnace capable to melting up to bronze for casting and forging. Being that I am on an island, the cost of shipping anything here is pretty high so I am trying to source whatever I can locally.
First hurdle was fire clay for the refractory mix, after some research I found a beach cliff which had collapsed to reveal white clay, so off I went.
Once I had collected a bucket of it and got home, I quickly fired up the blowtorch to see if it was the right stuff, seems ok.
Once I had done that started drying it all out and sieving it into a new bucket and ended up with this.
Next I turned my attention to the burner to make sure it was working ok.
Once that was checked, I picked a 47kg propane bottle, de-gassed it and threw it on the fire to remove the paint.
I then cut the bottle in half (I do not know if I am going a bit too big here for what I need but I thought better go large and not have to make a bigger one later)
I then cut some 5" heavy pipe and the corresponding hole in the side of the bottle.
The jury rigged the burner to test it for fit, I am hoping to be able to vary the heat by moving the burner in and out of the furnace on a rail.
That is where I am up to so far, and comments or criticism appreciated ;)
