To hold the deinonychus’ head onto mine, I used a construction helmet.
The modeling process involved significantly simplifying the model, making it practically lowpoly. Among other revisions, I removed the teeth and closed the nose.
After issues with the construction of a previous year’s Lewis head, I decided to print the model on a single sheet of paper. This allowed me to avoid the awkward step of mating different individual sheets of paper, and skip straight to cutting and folding the papercraft.
The paper model was quite floppy, so for internal strength I worked in several sections of wire to provide reinforcement. I left several triangles in the model open.
Most spray foams use a flammable gas as a propellant, and a toxic solvent, so I did the foam portion of this project in the summer, with my kitchen windows wide open and a fan blowing. The head took a week to stop smelling.
Several areas of the skull were deformed by the expansion of the foam, so I had to make revisions to the skull using knives, and then glue paper on over the exposed foam.
Painting was a simple job with several coats of matte white spraypaint. I filled the eyeholes with stretchy black cloth, and added some dollar-store lights
To aid in your effort, see the following photo logs:
Optionally, sink another eye hook into the front of the jaw, and one in the end of your dowel. Use the dowel for puppeting the jaw.
Enjoy. Only bite consenting partners.
There are two goals that a future revision of this head might involve: making it smaller, and making the jaw move without direct puppetry. I tried to use a Bowden tube design for indirect puppetry, but couldn’t get a good setup going.
