The following are details of the cones sitting in the drum in my Hamel 45 Gallon Drum
Mark 2.

Top view of drum showing top cone. Note that
this top cone is the one with the bearing for use with the motor.
A bicycle mirror can be seen in the bottom left corner taped to
the inside of the drum. This is used to help in placing the cone
into the notch of the cone below it. The mirror is removed when
testing.
