The following are details of the construction stand used in initial
construction of my Hamel 45 Gallon Drum Mark 2.
Here is the wooden stand with three opposing
rings holding three cones in balance. The bottom cone is sitting
on the tall oscillator.
Here is the same thing but from farther away.
Here is the same thing but from a top angle.
Note the tools in the cones to add weight so that the cones are
almost floating within the opposing rings. These were replaced with
bags of dirt in later versions.
Here is good view from a bottom angle.
You can just make out the gap between the opposing rings and
the cone rims.
