Sweetoliveforge

Hi everyone, I just ran across a black bear forge video online in which John Switzer mentions using an app for blacksmithing. It allows you to find all kinds of information about metal composition and what kind of quench goes with which steel. Does anyone know what it is? Anytime I look for this app on my phone I only find blacksmith rpg games... not useful. anyway my name is Robin, I’m new to this forum. I run Rapuzziironworks down here in New Orleans, LA. Any help would be greatly appreciated.

i wanna store coke in a tall 55 gallon drum. how would yall cut into the drum to make a dispensary hole for the coke to come out? i dont have any power tools.
