In this video, I make a solid copper sledge hammer in my home foundry. I made pattern using fusion 360 and the 3d printed the patterns in a plastic called PLA. Then I made a sand mold with a sand called petrobond. I machined the casting on my milling machine and then mounted the sledge hammer head to a hickory handle.
