Wow!  I remember having a hand-crank plaster of paris rotomold for
making creepy monster heads when I was a kid.  Apparently, I'm not the
only one who had one.

<quote>PLASTER OF PARIS MONSTER MACHINE
I am trying to find the name of a great toy I had as a child, to give
to my son.
It is used for making hollow plaster of Paris busts and money-boxes of Dracula,
Frankenstein, werewolf etc. It was available sometime in the late 70's to early
80's, I thought it's name was something like "Monster Machine" or
"Monster Factory"
and I think it was made by Mattel but I cannot find any reference
anywhere on the
web.</quote>

Running a motor would sure beat cranking by hand (because it took 10-15 minutes
of turning IIRC to make it work well).
