So I'm working on an actual "lifesize" Chief for my game room. I'm doing the helmet first. I have completed (except for final details and painting) a wearable chief helmet, but this one won't be wearable obviously using the same pepakura file.
Because it wont be wearable, I want to fill it with some material to provide rigidity, but not make it unreasonably heavy. I've considered many different materials, but I haven't really found a "perfect" solution.
I've considered building sealing foam, or expanding foam, not sure of the technical name. But I'm afraid the adhesive properties as it dries will work very well inside the helmet and basically explode it.
I've also considered lightweight hydrocal, but I'm not sure how lightweight it actually is as I've never used it. Or if it's adhesive properties will be good enough once it dries.
I can also brace the inside of the helmet with cut-to-length pieces of wood or other material if needed, then fiberglass them in.
Anyway the reason behind it is that it will be much easier to add detail if the helmet is filled with something I can actually work into. It will also allow to easily mount this thing on a rod for placement on the body.
Any ideas would be appreciated!
