Metal Foundry

[Gambit]

its not a great Metal Foundry but it will work
this wont make swords and horse shoes unless you modify it
but people who can do very minor blacksmithing or jewelry crafting or model metal casting has a hobby such as planes cars etc etc
remember bronze is copper / tin just wanted to throw that out there

to give ideas how to
note do not! make knuckle dusters I'm sure they are and no in some states and for the love of god do not quench the metal in water!!! use oil such as motor or any kind of oil just remember some oils will cool faster then others
water cools to fast and will crack or bend your items
also use boric acid cheapest way is the dollar store roach killer

Pretty slick thinking with the steel wool. We used to use chicken wire for some of the thin stuff at the precast plant
