fascinating Toys Possible
From Easy-to-Work Plywood
Fascinating new children's
toys each containing hours of
playtime enjoyment, are easily
within your reach if you build
thenr yourself. And building
them can be a simple enjoyable
pastime when you use big, easy-to-handle
panels of fir plywood.
Some of these toys are avail
able only if you make them your
self. No manufacturers are pro
ducing all of them. Several, how
ever, are being made by west
coast companies.

in order,
The Play Plans are notched
construction pieces with which
children may build walk-in size
projects without nails. Three
standard panels of fir plywood
form the entire set. This is one
of the simplest home craftsman
projects on the list. Cutting it
out will take part of one day on
a week-end. A small version of
this toy is made by Hogan-Spar-
ber Products Co., Oakland, Calif.,
under the name "Junior Contrac
tor Set."
The Giant Building Toy in
volves seven basic pieces cut
from one panel of fir plywood.
The seven pieces are notched tri
angles, providing parts for an
almost inexhaustible supply of
backyard 4 kid-struction" proj
jects. In this respect, it is similar
to the Play Planks. However,
the pieces are of a radically dif
ferent shape and are assembled
with birch dowels. The set is
being manufactured under patent
by Martin Metal & Associates,
Sausalito, Calif., and the Muir
Co., Mill Valley, Calif.
The Space Raiders' Club
House is what the name suggests:
an outdoor play structure shaped
like a rocket ship, designed for
easy construction with four pan
els of fir plywood.
Each of the projects has been
amateur-tested for building sim
plicity, durability and appear

short legs, and some will grow

Douglas fir plywood has had
many nicknames in its long and
colorful career. Some have call
ed it "the carpenter's friend";
others have named it engineered
wood, America's busiest build
ing material, and the jack-of-all-
trades of the building industry.
This year in the Golden Jubilee
year a new nickname has been
added. It is "the 20th century
wood miracle. ,

If you are going to build a ply
wood boat, here's some valuable
information assembled from lab
oratory test and experience data
collected by the Douglas Fir
Plywood Association.
Construction of a plywood
boat requires attention to a few
details that may or may not be
required in conventional con
struction. Such attention will be
more than paid off in trouble
free operation.
The average plywood boat has
only four seams to a side, and if
they are well laid up in glue or
composition when the boat is
built, they may very nearly be
forgotten. This is doubly im
portant if the boat is to be taken
into and out of the water-frequently.
The plywood planking
won't shrink and swell, alter
nately leaking and pressing out
the caulking. A board-planked
boat is expected to leak for the
first few days until the planks
swell against the caulking, and
caulked seams of cotton and
compound cost an owner a tidy
sum during the lifetime of a
board-planked "boat.
Probably the most important
must in building a boat with ply
wood is to cover the panel
edges. If any deterioration - oc
curs, it is along the edges where
the alternate layers of veneer
and waterproof glue are exposed.
Even when buried in other mem
bers, these edges should be
sealed to prevent the entrance of
moisture.
Provided a boat is pot to be
subjected to unusual . stresses,
one-quarter-inch plywood may
be used for planking on craft up
to 16-feet in , length. The three
eighths inch thickness is recom
mended for boats out of the
pram class. However, larger
boats call for thicknesses up to
one-half inch, often gained with
two layers of quarter-inch glued
along the entire facing surface.
' For an outboard boat, ply
wood is lh transom material.
The constant hammering of an
.outboard motor will cause a
transom of glue-doweled, or
otherwise jointed boards, to work
at the joints. This is not true of
plywood. Pound for pound, the
material is actually stronger than
steel. The glue bond is tested to
be stroneer than the wood
fibers. A plywood transom, prop
erly seated and with sufficient
knees and good corner bracing,
should give no trouble jf or the

costly specialty plywoods are
often used for "show" in some
places. Many of these more ex
pensive surfaces are bonded on
fir plywood cores and have gen
erally the same weight and

pleted extensive tests to provide
the structual data for acceptance
of this system by both Building
Codes and FHA authorities.
Conventional plywood floor

ranges up to -inch thick on
supports up to 24-inch o.c. The
thicker panels in the new sys
tem permit a reduction in di
mensional lumber .and offer
time labor cost and construc
tion advantages which lead to
several contingent savings. Beam
spacing of 4-feet is probably the
most practical for the system
because it conforms with ac
cepted building modules and' is
most adaptable to the standard
8-foot fir plywood panels.
DFPA test data shows that
one-inch fir plywood is entirely
adequate as a subfloor over sup
ports spaced 4-feet on centers.
Such a floor readily takes loads
of 75 to 90 pounds per square
foot with minimal deflection,
and a more than ample safety
factor.

IN BOTH AMATEUR and commercial construction fir plywood
planking goes on all types of pleasure craft because of its many
basic advantages. Here is the construction of an 18-foot cruiser.
The fir plywood eliminates hundreds of feet of seams, reduces
maintenance to a minimum and insures high-strength, lightweight
hull for your boat.
Development of Materials
Major Task for Industry
Development of new materials
to ease the builder's work, pro
duce longer lasting structures
and expand the ways to use
standard fir plywood is a major
task in laboratories of the Doug
las Fir Plywood Association.
The DFPA effort is part of
west coast plywood manufac
turers' continuing aim at main
taining industry growth pro
ducing more jobs by opening
new markets.
Here are some examples . to
show how well this research is
paying off for the benefit of the
West's economy:
Research by DFPA structural
engineers in the association's two
laboratories at Tacoma, Wash.,
and Eugene, Ore. developed
the method of using fir plywood
for roof decking in large build
ings such as warehouses, schools,
theaters, markets, and other in
dustrial structures. Designers
now specify fir plywood for
these structures in many in
stances where extra rigidity and
strength are needed to with
stand earthquakes and hur
ricanes The DFPA research proved
that plywood, nailed according
to a schedule devised in the lab
oratories and in actual construc
tion tests, is a highly economical
method of achieving superior
lateral strength on large, flat,
plane-like roofs.
The Federal Housing Authori
ty bases many of its structural
requirements on ' industry re
search. Studies proving ply
wood's strength paved the way
to FHA approval of thin ply
wood construction over wide
rafter spacing. This created
major structural economies in
home building at no sacrifice in
strength.
Research of this type pays off
in sales. In only one instance,
DEPA laboratory data saved
$2,800 in construction costs of a
Washington school: Architects
used this data as a basis for
specifying a plywood roof deck
over widely spaced supports.
Using similar research data, a I
Seattle builder pioneered a sys
tem of fir plywood floor con
struction which saved $500 on a
$15,000 house. - Other home
builders have reported savings
up to 50 per cent in wall and
roof construction where they
used fir plywood according to
data developed by DFPA re
search laboratories. .

Today we salute the fir plywood industry which this year
Is commemorating its 50th anniversary. Since its beginning
the industry has grown from nothing to a $370,000,000 per
year giant . . . and is still growing..
Fir plywood produced only on the West Coast' is sold
.everywhere. It is used to build millions of useful things, and
new uses are being discovered constantly.
We are fully aware of the importance of fir plywood to
the Jackson's County's economy, and we will continue to lend
our support to the industry and to its efforts on behalf of fir
plywood's increasing popularity and usefulness.
