Well this is just my two cents, I love the helmet and would like to know how you scaled it. The chest, since it is paper(someone correct me if i'm wrong) couldnt you just splice at the bottom and bring the pieces together? just curious? I mean after hardening it you have to cut it anyway and strap right? At the bottom rib sections, remove a piece from both sides to bring the bottom back together and it should fit? Eh just an idea i'd hat to see great work thrown away because of a minor resize.
