hello! I am going to be building a metal replica of king Leonidas's helmet from 300 after I finish up my metal iron man helmet. I will be using 18 gauge sheet steel. I looked into making it out of bronze but a sheet the size needed to make the helmet was $1500 so ill just stick with steel. this is just a test I used a pick hammer to add all the hammer marks and hammered the face of the helmet on the concrete to add all the little pits/texture. For just a quick test it turned out pretty good. Also I will be making a video of the build and posting it here too.
