Backyard Foundry

I made this a few years ago from an obsolete propane tank. The lining is refractory cement with perlite added for insulation. The burner is made from iron pipe using a reduction fitting as the venturi and a capped tee with a #60 hole drilled through the cap for the gas jet. It is quite efficient and compact for the job it does. Current project: To make a Graphite clay crucible that will solve the problem of using steel crucibles which have a limited lifetime. Also check out my foundry extension video to see how to properly mix the fireclay and add the perlite insulation without sacrificing the working surface of the foundry. The lining is Harbison Walker KS4 which has stood the test of time and well worth the money. have fun bob
