I make sliced weapons from foam, they have no moving parts but are very light and extremely durable. I documented the process for making an H3 shotgun here: www.squidoo.com/how-to-make-halo-weapons
All the 4shared links are dead, do you happen to have marcus, anya or any female foam templates? If so, can you email them to me, would greatly appreciate it. chuy124@hotmail.com thanks in advance.
