One of the things I learned wearing my vented Steampunk Top Hat for 3 days at Wild Wild West Con was that it was darned heavy!
The hat weighed just over 15 ounces (426g) and I had a sore spot on my forehead after wearing it all weekend. Brass is darned heavy!
To reduce the weight, I removed all the brass nuts and aluminum washers from the inside (where no one sees) with nylon nuts (foregoing the washers, I don’t think it needs them):
This reduced the weight by over 1.8 ounces (53g to be precise)…more than 13% less! Already it feels dramatically lighter…if I still have issues I may reduce the weight of or remove the goggles entirely…
