In this issue, we are publishing several accounts of ‘steam
school’ programs conducted by various organizations. This one

Newsletter, Vol. 15, No. 2, July 1997, P. O. Box 874, Willits,
California 95490.

Due to popular demand requests from you, the members of Roots of
Motive Power, we sent out notices for the first Steam Engineering
and Safety Class in the last Roots Newsletter. Within a few days,
the Museum was besieged with people wishing to attend the class. We
cut off enrollment at 50 students for the April 6th class and
immediately set a date in May for a second class to handle the
overflow of 30 additional students. The majority of students came
from Sonoma County, where an article about the upcoming class was
printed in the Santa Rosa Press Democrat.

Developing a curriculum for the one day class was difficult,
since steam engineering filled several semesters at any university.
Besides wanting to hook students on the wonder of steam power, we
wanted to stress the all important safety aspects of operating in
the public eye.

With help from Bob Hinerman, Bobbie Yokum, John Bradley, Chris
Baldo and Jim King, we pulled together a curriculum that
incorporated the Roots Safety Guidelines and Operating Rules, the
booklet adopted by Roots in 1991 to cover the operation of all
machinery in the collection. We knew that one did not become a
steam engineer after a one day class; but that the information
imparted would be a first stage to be followed by months of working
with steam in Roots work days and steam ups or other

The class was structured in two parts, a classroom session from
8:00 a.m. to 1:00 p.m., and an outdoor session from 1:00 p.m. to
5:00 p.m. involving equipment in the collection. The classroom
session covered such subjects as the properties of steam, boiler
construction and boiler maintenance, the steam engine and machine
operation safety. Bob Hinerman and Chris Baldo handled the
classroom instruction. With an ample supply of coffee and home
baked goodies from Bobbie Yokum, Vi Hinerman, Norma Avery and Norma
Branson, the students made it through the difficult part of the day
with only a few sharp elbows to awaken the snorers. The students
proved to be a bright group coming from many areas and from many
interests. Some were involved with other volunteer groups operating
steam equipment, several owned steam equipment themselves, and
several were interested in joining Roots activities and becoming

The outdoor portion of the class involved students steaming up
four pieces of equipment in the Roots collection under the watchful
eye of experienced Roots engineers. We utilized the Williamette
Humboldt yarder, the American Hoist and Derrick double drum winch,
the Raymond pile driver and the Marshutz and Cantrell spool donkey.
After being divided into four groups, the students rotated to each
piece of equipment on the hour. Starting with a cold boiler, the
students built a fire, watched steam build to operating pressure,
and then operated the machines under steam. It is a process that we
do time after time, and never fail to learn something new about
steam along the way.

Roots would like to thank the many students that made the class
a rewarding process and hope that they continue their careers as
apprentice steam engineers. We are especially proud of those that
have continued to work on Roots projects over the last few months.
Our group will be better for the new blood and the understanding of
the responsibility involved in operating for the public. We hope to
incorporate comments about the classes into the 1998 class to make
it an even more rewarding experience.

In closing we would like to thank the many Roots volunteers who
helped put on the class: Shad Kelly, Bobbie Yokum, Shane Grupp,
Danny Mihelcic, Kirk Graux, John Bradley, Vi and Bob Hinerman,
Chris Baldo, and Norma Branson.

A major thank you also goes to Dan Taylor and the staff of the
County Museum for co-sponsoring the event and handling the reams of
paperwork involved.
