to know your VMMV staff & vehicles
In this section we will introduce you to the people and armor
of the Virginia Museum of Military Vehicles. We will chat with
the VMMV staff, so that you can get to know the people who "keep
'em running" and work so hard behind the scenes. And also
provide a behind-the-scenes look into the history of individual
vehicles in the VMMV collection. In this, our eleventh newsletter,
we highlight the activities of our volunteers during a recent
Volunteer Work Day!
Volunteers Show Tropical Storm Hanna Who's the Boss
Hi, I am Bruce Oppenhagen and I am the Volunteer Coordinator
here at VMMV. My job is to interface with the VMMV staff and
work with the volunteer cadre to support the activities at VMMV-such
as Volunteer Days and preparation for our Open House. And I
want to tell you a little bit about our latest project
Saturday, 6 September, we had a Volunteer Day at VMMV to work
on a technology testbed of the Expeditionary Fighting Vehicle
(EFV). You may remember the CAL-1 from our last newsletter.
Over time the vehicle had wood and metal cladding added to the
basic hull for testing purposes, altering her silhouette. VMMV
wanted to remove this vis-mod and restore the CAL-1 to her original
configuration. So we consulted some reference material, got
an idea of the work ahead and with the staff of VMMV I organized
a Volunteer Day.
what a day it was. It just so happened that Tropical Storm Hanna
was making a visit to the East Coast on Saturday and boy did
she leave a mark with high winds and drenching rain. But that
didn't dampen the enthusiasm of the VMMV volunteers as over
15 highly motivated folks showed up.
the expert eye and tutelage of VMMV Staff Member Marc Sehring,
tools were handed out and the job of removing the CAL-1's exterior
began. Sawdust flew as cordless drills, pliers, pry bars and
all manner of wrenches were used. The volunteers split up and
attacked different corners of the vehicle and worked as self-organizing
teams. When and where needed, work was stopped to noodle thru
a particularly difficult section of the project.
by the end of a wet and windy day, the Volunteers all had a
smile on their face as they stepped back to admire their handiwork
CAL-1 with her original form back. Perhaps a little dirty and
tired, but with high spirits at a job WELL DONE!!! Thanks Guys!
you would like to volunteer at VMMV, please register via the
volunteer page on the museum's web site. Thanks, Bruce.
The lexicon of armored vehicles is filling with a bewildering
amount of acronyms. And at VMMV we have a few of our own. Here
we will have the VMMV word of the day so you may better understand
the conversations you might overhear at the museum.
From the mid-19th century up to the 1970s, the British used
the Whitworth, or the "Halford" unit of measurement
for nuts and bolts before they standardized on the US SAE of
Unified National Fine (UNF) system. Although Whitworth nuts
and bolts have common English-sounding names-such as "half-inch"
or "3/4 inch"-they are not the same size as the SAE
specification used in the United States. They also have different
pitch and shape for their bolt threads.
bolts are not measured across the flats of the head like you
are accustomed to, but the diameter of the nut or bolt the wrench
is intended to fit. Mixing a Whitworth wrench with an SAE bolt
will result in a ruined wrench, busted knuckles or a stripped
.what a mess.
VMMV has to have a full spectrum of wrenches, nuts and bolts
in many different sizes-metric, SAE and Whitworth for example.
During the Open House you might spot a Volunteer with a half
inch wrench in his or her pocket, but it could be a half-inch
Whitworth in disguise for a bolt head that is actually 0.920
inches across. Those folks wrenching on old British sports cars
are also likely to have a set of Whitworths in their garage!!
