Ready for some hot metal! The weights are
necessary to keep the liquid metal from forcing the 2 halves of the mold
apart. When this happens, hot metal comes squirting out the sides...dangerous and messy.
This is my old furnace. I use it now almost
exclusively to melt zinc using propane as the fuel. The piece of firebrick
over the vent helps keep the heat inside.
Here is a shot of the furnace running and zinc ingots in the crucible.
30 minutes later the zinc is ready to pour. No shot of that as I can't pour and photograph at the same time.
Here one mold has been poured full and the weights moved to the second mold.
Here is a shot of the casting removed from the
first mold. I'll use a band saw and cut off wheel to remove the
sprue and gates.
I use a high speed rotary tool with a carbide bit to remove the excess metal flashing around the edge of the casting.
6 castings and the original pattern. Nothing to it!
