I was asked once if I found the black iron to be really hot in the sun. Interestingly enough, I think it radiates the heat as quickly as it picks it up...there is really not all that much difference in internal temperature between a matt finished "shiny" helm, and a black finished "brain bucket".
I made this helm to fit a little lower on the face than usual. I think that face plate could be raised up some three quarters of an inch and still function. And I will do that if the customer feels that there is just too many layers of padding on the top of his head for comfort. Two layers of half inch foam should be enough. If we go to four layers, well, I'll move the face plate up a bit.
The hinge points are 3/8 in rivets, and the face plate is kept from being driven back into his chin by a pair of solid shoulder rivets, clearly shown in the above picture, although perhaps better shown in the middle picture. The strap is considered to be sacrificial, and extra holes are drilled to enable the customer to tie the visor down with a spare shoe lace if the strap breaks.
