 [[User:Gori|Gori]] made a small foundry out of a soup can, a propane blowtorch and some refractory. This works reasonably well and never fails to gather a crowd. It only melts approximately 0.2 l of aluminium, and this is clearly not enough to do any real work.

			The dimensions of the barrel are 590 mm high and 375 mm diameter. With a suspected 50mm refractory lining this should give an inner diameter of around 250 - 275 mm. Inner height would be around 450 mm (excluding a plint for the crucible to sit on. Maximum crucible dimensions should be around 200 - 250 mm outer diameter, and a height of 350 - 400 mm.
