Ergo Proxy is a science fiction suspense anime television series, set in a future where humans and androids coexist peacefully until a virus gives the robots self-awareness, causing them to commit a series of murders.
This is the main character’s shotgun from the series.
I started by cutting the pistol grip halves from 1/2″ MDF.
I wanted to be able to remove the trigger for painting so I cut the trigger guard in halves from 1/4″ poplar. The trigger in inserted from the top and pivots on a nail.
I used a compression spring from a ballpoint pen to give the trigger its “pew pew pew”.
I used a router to carve out a recess for the trigger assembly. It will be glued in after painting.
To make the grip plates, I used 1/4″ MDF to make a simple box around the pistol.
I then routered the edges and sanded the grip to shape.
I lathed the upper barrel cowl from basswood.
The pump grip was routered out of basswood as well. Half of the groove was puttied over to create the shotgun’s distinctive ridges.
I drilled out the center so that it could slide on a 5/8″ dowel.
The bracket that holds the pump tube and barrel in place was made from two pieces of 1/4″ poplar glued together.
This was my solution to make the pump spring forward. Rather than weaken the pump tube with some sort of internal spring configuration, I decided to hide the mechanism under the gun’s shroud.
The shroud was constructed from 1/4″ MDF.
The lanyard loop was made by bending 1/16″ steel wire to shape.
For the exposed barrel, I sanded the inside of PVC pipe so that it would slip over the barrel dowel on either side of the bracket.
The final shotgun. I used gloss black on the grips, dark grey on the shroud and Metalizer gun metal paint on the other parts.
The lanyard loop can swivel out or lays flat against the butt.
