Complete instructions on building this electric furnace from cheap, mainly scrap, materials. Use the result to heat treat metal, forge, temper, anneal etc as well as melt aluminium and bronze. Electricity is cleaner than charcoal and gas, if more expensive, and it is all there - in the wall! Also keeps the metal molten at a certain temperature until YOU are ready for IT. A great project with a useful end result. 67 page illustrated paperback written by Dave Gingery and published by Lindsay Publications. N.B. This is an American book, so remember to make appropriate alterations to the electrics.
