@:pumpkin_jump: Saṁain Goat :pumpkin_jump: thanks! found it instantly. its hard to find this stuff when you dont know what its called. chatgpt helps with dumb questions but not always right

 @:pumpkin_jump: Saṁain Goat :pumpkin_jump: yea i saw this video before i think. you'd need to anneal iron but aluminium is so soft i'm sure you don't need to
