Cast from smooth-cast roto, 1/4" thick, 2.5 lbs. Rim opening 6 1/2" x 8 1/4" , it's 27 3/4" outside circumference. My head is 6 1/4", 22" round and fits me perfect. The hinged version has friction slide hinges to allow me to slide the face plate up and back manually. I also installed clear safety lenses and an e-l lite strip for the glowing eyes effect. I aslo put on foam pads with felt for comfort. Let me know what you think!:cool
Man! That's a Really nice looking helmet!! Do you plan on making a complete suit?

Can you tell us more about Smooth-cast roto? Is it very rigid or somewhat flexible?
I'm looking for an alternative for helmet casting, because I'm getting bored of the hand-laying fibercloth.

I've used Smooth-on's "Smooth Cast 300" for slush-casting and it works pretty good. It sets up in about five minutes and has very similar specs to "Smooth-Cast Roto"

I've found smooth cast-roto very easy to work with, much better than doing it out of fiberglass. Smooth cast 300 flashes too fast and you might get a clump. With an open mold like mine I can easily chase it around the mold and see where it's flowin. Also several thin layers right after each other will give the best results. Mine has 5 layers , 8 oz. for total weight 40 oz.(2.5lbs)
Have pics of the wip on this badboy?
So do I. I've been casting helmets with SC300, too, but no matter how much fiberglass I add, it always stays, somewhat, semi-flexible. Plus, the more fiber-cloth and resin you add, the more time you spend casting.
Something to ponder on. Can you squeeze your helmet? is it flexible or totally rigid?
