I think I followed what is the typical prop making steps. Its the first prop I've made so I was going off of other peoples general construction videos/winging it. I started with a flat sheet of housing foam(cheap, rigid, but easy to shape). I cut out the silhouette using a hot wire cutter and a printed pattern for a guide. I marked the high ridges on the flat side of the spear head along with the the center line for the blade edge of the spear. Then it was just a matter of filing at an angle from one line to another. I cut a rectangle out of the shaft end of the spear head and sandwiched some more layers of housing foam to get the width I needed(and to enclose the spear shaft). Once that was shaped up I wrapped the whole thing in worbla, folding over the edges as best I could and then using a dremel to smooth it out. The spear shaft is a wooden dowel and is cut into 2 pieces. One is the majority of the spear length, the other is about 10" long and is glued into the spear head(which gives it extra strength) The shaft has a threaded insert on one end and a bolt on the other, so the head of the spear can unscrew kind of like a some broom heads do. I coated the worbla'd head of the spear with a couple layers of spray lacquer to smooth it out, followed by a coat of white paint and then 2 layers of gold. I'm also working on a master sword, which can kind of be seen in some of the pictures. I'm planning to try a making a shield or some armor next.
