Re: melting aluminium

Smoke,Dave Gingery has a book on building electric furnaces. The book
is called "Lil Bertha" and he does a fine job on design and building
the things. I built one and have given it to a friend as I got too
old to mess with hot stuff. The furnace worked for many years and
melted Al for many castings. It took about 1 hour from a cold start
to melt a quart (about 56 cubic inches). The power at 220 volts input
was 1800 watts (9 amps). You will enjoy the book if you can find it
and the furnacing and casting can be done in your basement if you use
clean aluminum.
