Got into this about 8 months ago. Since then I have built 3 forges, 2 of them coal/charcoal and one that runs on propane. The picture is a leaf I made that started out as a piece of 1/2" square steel. I have made a number of tools and decortive items. Like metal detecting this can become an all consuming hobby. I think I may have found a use for all of those rusty bits of junk steel that I seem to be so well at finding.
