places instrumental in
his mining background were
Uranium City, Saskatchewan;
Wabana, Newfoundland;
Esterhazy, Sask.; and
Lochlomand, Nova Scotia.
In August 1971, he accepted
the position of production
manager of Sifto-Salt which he
held until this promotion. How
does he view his added respon-
sibilities?
"This job is a challenge as
plans are being developed for
this plant that I'd like to be
part of," he stated,
Succeeding Bill Coughlan as
production manager is Karl
Butler who has been` a
Goderich resident since 1969
and has a total of 18 years
working experience with Sifto-
Salt. Karl began with the com-
pany as a draftsman in
Amherst, Nova Scotia.* He
spent four of those years in
college obtaining his Civil
Engineer papers.
In 1969 he became the new
project manager in charge of
the new Sifto expansion which
was going on at that time, Karl
remained on staff as the
resident engineer until his ap-
pointment as production
manager.
Karl' is well known around
town being a Lions Club mem-
ber and treasurer of the Young
Canada Week Committee. He
coaches minor hockey as well
Coughlan succeeds
as assisting with the cub pack
which meets at North Street

Bob Chapman has been ap-
pointed to the newly created
position of , chemical superin-
tendent. Basically Bob remains
in his present position of plant
engineer but receives the added
responsibility of consultant in
the operation of the Louisiana
mine.
Bob began with Domtar in
Montreal in 1951 and came to
Goderich in 1958 as plant
engineer. He has been very
active in the community and is

The rocket soars up and up un-
til it reaches its apogee or peak
altitude and begins to turn over

Throughout the country,
thousands of youngsters bet-
ween the ages of 8 and 16 are
enjoying the fast growing sport
of model rocketry. For them,
launching the "bird" they have
built with loving care and
seeing the parachute deploy as

toward earth at the end of its
powered .flight is the most
rewarding feeling in the world.

greatly reduced sizes it faith-
fully duplicates what is hap-
pening at Cape Kennedy when

rockets is sent, upwards.'
Model rockets can be seen in
this area blasting their way
skyward as a group or young
enthusiasts meet periodically in
one . of the,' fields on Jack
Scaman's farm just isouth of
Goderich on Highway 21.
The five youngsters who are
Kevin and Rob Bundy,' Dave
Smith, Phil Main and David
,lest are under the guidance of
r "G.D.C.I. chemistry teacher
Doug (Doc) Bundy.
Doug first became interested
in model rocketry three years
ago when he was living in•
L'irantford where he saw a
rocket display.
When his sons and their
friends decided to take up the
hobby seriously, Doug joined'
the Canadian Association of
Rocketry and was- forced to
write tests to obtain a firing
supervisors licence in order to
be able to fire the rockets. It is
now government law that a
person must have this licence
to purchase rocket engines.
While in Brantford, his club
which called 'themselves "Space
Squadron", organized a couple
of demonstrations which accor-
ding to Doug "were well atten-
ded."
In August 1972 the Bundys
moved tt Goderich. During the
time that Rob and Kevin were
making new friends, things
were very slow in the rocket
hobby. Once new friends were
made and things were settled,
the interest in building rockets
picked up and work began in
the Bundy basement. Since that
time they have had 'several
launches. Each boy has built at
least one rocket.
The basic model rocket
which may vary in length from
about four inches to nearly four
feet, consists of a nose cone
made of balsa wood or plastics;
a launch lug which slips over
the launch rod to provide
guidance at launch; a recovery
system which is a parachute or
streamer; and an engine which
is discarded after each ?light.
Model rockets are usually
sold in kit form but rocketeers
often prefer to design their own
models and buy individual
parts. Regulationslimit the
weight of the rocket to 16 oun-
ces at liftoff and the , model
must have a true and predic-
table flight.
The„ basic operation of a
typical model rocket as based
upon the design of both the
engine and the model.
The model rocket engine is
prepared for ignition by first in-
serting an igniter wire so that it
comes in contact with the
propellant. When an electrical
current passes through the wire
it will be heated red hot and
ignite the propellant. The bur-
ning propellant creates tremen-
dous pressures inside the
engine. These pressures cause
the rocket to liftoff.
, .,;:After all the propellant has
been expended, there is what is
called the burn -out which im-
plies that the propulsive power
of the engine has ended. The
rocket however will continue
climbing on its flight path using
the momentum that it built up
during the thrusting stage.
After burn -out, the engine
still has a job to do. The heat
created and remaining from the
burning propellant will ignite
the delay charge. The delay
charge actually has two pur-
poses. One, it allows the model
to coast to its highest joint, the
apogee, before the recovery
device is deployed, and secon-
dly, it provides a smoke trail so
that the rocket path can be
followed.
After the delay charge has
been expended, the ejection
charge will ignite immediately
and cause a tremendous expan-
sion of gases. This expansion
creates a high pressure inside
the engine that pushes toward
both the front and the rear of
the rocket. It forces everything
at the front of the rocket to be
pushed that way thus blowing
the nosecone off and releasing
the recovery device. With the.
recovery device deployed, the
model will float gently back to
earth to be prepared for
another flight.
Mr. Bundy explains that
"this hobby is a very worth-
while one to the boys as they
not ° only have fun but also
learn scientific things.
"Many dtysT when the
weather is bad outside, the
boys come over and spend
hours working on their
rockets." he added.
Doug Bundy also expressed
his desire to have this hobby
remain as such. He did say
however that he would like to
see the school (G.D.C.I.) adopt
model rocketry _as an extra-
curricular function.
