The Amazing Screw-On Head is a robotic agent for Abraham Lincoln in Mike (Hellboy) Mignola’s comic book and animated pilot.
He is capable of attaching his head to various robotic bodies but I decided to stop at the neck.
After basing a 3D model on the animated character, I imported it into Pepakura and converted it into a paper model. I then printed it out and assembled it.
I sealed the paper with a coat of fiberglass resin. The screw at the base of the neck would be made separately.
I slush cast several coats of plastic resin inside the paper until I had built up a wall thickness of 1/8”. The paper was sanded off and facets smoothed.
A further refinement of the surface.
I capped the neck with a disk of styrene and attached a cylinder of basswood to fit inside the screw shaft.
The plug socket for the back of his head was cut from 1/4” MDF.
The shaft of the screw was made from a 2” ABS pipe. I lathed the end cap from a scrap of basswood. The paper model screw was assembled as a guide.
The end cap glued into place
Led astray by the paper model, I originally made the screw threads reversed. The correct threads were made by glueing styrene tabs to the pipe.
I built out the bevel of the threads with epoxy putty and then sanded it smooth.

The secret of the stand…a nail is glued into the base that fits into a hole in the screw.
