I read Vern
on the new Figure 1
in the April issue of Nuts & Volts.
I was privileged to be present
at a demonstration given a good
number of years ago by Rockwell
Automation of their version — the
Retroencabulator. When I first heard
the description of the device, my mind
reeled because of the tremendous
amount of technology that they were
able to integrate using Dodge
gears and bearings, Reliance Electric
motors, Allen-Bradley controls, and
monitored by Rockwell Software.
The fact that the newest version
is far more cost-effective just shows
how far the industry has progressed.
Also, the mounting bracket you
devised is truly innovative. Though it
is simple in concept, it would take a
very good machinist to construct it.
However, the hex nuts you use to
secure the Digiencabulator to the
bracket are of the incorrect type.
Standard hex nuts won't work properly
in this application. What is needed is
the design sometimes attributed to
Escher. (See Figure 1). If you are
unable to procure the Escher hex nuts
(Home Depot rarely carries them),
then the famed Rick should have no
problem machining them, as well.
Other than that minor correction,
it was a fabulous article!

I enjoyed Vern Graner’s column
on the Digiencabulator. I have been
using the earlier Retroencabulator
device to study the Hillnor response
(i.e., mass body movement) of
mating male Roosevelt Elk of the
Olympic National Forest (ONF) for
