Gene Simmons Destroyer Costume

Step 4 Make Spikes. Lots of Spikes.

I then made 16 spikes out of some Sculpey I had already, and set a small machine screw into the bottom of 14 of them before baking the Sculpey, leaving about 3/8 inch of the threaded end poking out. Then I baked the spikes and set them aside to cool.
To make the spikes, I made a mold out of some milk jug plastic by drawing 4 triangles connected to each other along a side, cutting the resulting shape out of the milk jug, folding along the lines of the triangles and taping the edge closed, leaving me with a hollow plastic pyramid-thingy. My spikes were about 1" square at the base and 2" tall. Then I pressed the Sculpey into the mold, inserted the machine screw, leveled the bottom, and carefully removed the spike. Repeat 15 more times, omitting the machine screw for the last two. The two screwless spikes are used for the gloves in a later step.)
I drilled holes in the armor pieces for the spike's machine screws in the appropriate locations (2 for each forearm and shoulder cap, one for each upper arm, chest front and back) and installed the machine screws through the holes with a dab of Amazing Goop and a hex nut for each one.
Because I had not made the spikes to exactly fit the curve of their corresponding armor piece, there was a slight gap at the base of the spike, which I covered with a bead of high temp hot glue to simulate a weld line (this detail occurs on the real Gene Simmons’ costume as well, so it’s not really a cheat).
