So, I got a wild hair and did cold cast Boba helmet in bronze! When I do a normal aluminum helmet, I buy 5 pounds of aluminum and I can get about 10 helmets out of that. To make this helmet, I used 2 pounds of bronze powder! 1 pound of bronze powder costs about $22. Yep, this helmet comes in at about 2 pounds heaver than a normal helmet at a cost of over $40 for the bronze. But, I think it is well worth it. What do you think? If you would like one, please drop me a line.
