It ain't much, but there isn't much invested with what is sitting there right now. Maybe $50? Most of it is scrounged or repurposed.
I've two gas grill forges like that. I rebuild the lessor one trying to improve them.
I've got my 5th hunk of metal to use as an anvil coming to me next time I go to my folks.
I real forge and anvil would be nice, but I'd rather make noise and small bits of metal even smaller now than later when I can afford the "real" tools.
