Rockin’ Granny

There’s something completely unsettling about a decrepit looking old lady slowly rocking back and forth in her chair.  If you know a decrepit looking old lady then you’re half way there, but if you don’t, you can always follow ScareFX’s tutorial and make your own Rockin’ Granny prop.

What you’re building in this tutorial is a self contained rocking mechanism that you’ll build your Granny on top of.  The frame is built of 2×6 material with the wiper motor mounted vertically.  A piece of aluminum flat bar connects the wiper motor to a piece of 2×6 that is connected to the base via a 4″ hinge which will allow it to rock back and forth when the motor spins.

The upper part of the Granny is built on the 2×6 that is hinged by connecting some 1″ PVC to the 2×6 and then creating some shoulders with the 90 degree elbows and adding some sections of pool noodles over the PVC for the upper arms.  You’ll need to add some prop hands if they’ll be visible.

The lower body is connected to the base and consists of a PVC T connection which connects some 1″ PVC to two 90 degree elbows and forms the legs.  Again, you’ll need to add some prop legs if they’ll be visible.  Once your mechanism and skeleton is complete, the entire device is connected to the rocking chair with clamps to prevent it from flying forward once it gets rocking.

After you’ve got everything clamped down it’s time to put the Styrofoam head on it and you’ll probably want to put a mask on it as well.  Oh, and don’t forget to put some clothes on Granny!
