Well, blacksmithing and Welding require a few tolls and some guidance (I’d say), but soapmaking seems pretty straight forward. I hear it stinks to high heaven though, but that you can use vegetable oil (if done right), bacon grease, tallow, or many things. A local lady hear uses frozen goats milk, and people pay if I recall about $8 a bar, or $20 for three.
I remember my great-grandma’s lye soap she brought with her when she moved from Ohio to Vegas, and one of the bars lasted 4-5 years. (It was a big brick, but still). It seemed unending, which I’m told is very true of homemade lye soap vs. the soap we buy in stores.
Yes, a local woodworking school has basic blacksmithing classes every once in a while. I think I’ll sign up next time they offer it.
