Backyard Adventures
Summer Projects
Backyard Adventures Building a sandpit, water table, and
simple toys can provide years of adventure... and a little
peace and quiet around the house.
The swamp maples are showing a hint of fall color, but
summer is still very much with us, and the outdoors is
warm, spring-bug free, and perfect for outdoor play. But
over the bleating of the TV in the family room comes a
petulant "Mommeeeee, whaaaaat can I doooooo?"—a sure
sign that school vacation is winding down. If the kids are
small, you find yourself barking, "Time Out!" more often
than you like. If you've a preteen, anything but a day of
mall-crawling is "Borrr-ing!" Everyone in the family is
anxious for school to start—children too, even if
they won't admit it—but there are still weeks of
freedom for them to endure ...for you all to endure.
What say you off "Barney" or "Hollywood 9-0-whatever-0,"
herd the kids outside, and all of you get to work building
a sand pit (or sandbox) big enough for serious excavating
and a waterplay table shallow enough to be safe for
toddlers but guaranteed to keep all ages intrigued, wet,
and cool through the dog days. Plus an assortment of
sand-building blocks and simple wheeled toys that are easy
to make and plenty sturdy but no great loss if left out in
the rain or under snow all winter. Together, they offer
much of the fun of a trip to the shore.
An adult must do all the power-tool work, of course; but
let the kids help dig the sand pit, measure and hand-saw
wood, hammer, and paint. Give kids a series of small jobs
they can complete success fully ...even if it does take
twice as long—or perhaps because it does.
Make the projects family fun rather than work. It's still
vacation, remember?
OUR SAND PIT
The best-used outdoor "toy" I ever made for our kids and
their little pals was the sand pit—about a cubic yard
(29 cubic feet or 50 buckets) of sand dumped into a 1 1/2'
deep, 3' x 4' oblong hole dug in the lawn of the side yard.
Singly or two to four at a time, the children would spend
hours there, building roads and caverns and hideouts.
Without much squabbling either; sand play is physically
active but focused. There were plenty of Tonkas and
homemade sand scrapers, scoopers, haulers, and building
blocks to go around. Plus, this was when Star Wars
first came out, and model Sand People were right at home
stalking R2D2 and 3CPO through the minidunes.
Now that the children are college age, the pit has gone
back to lawn and you'd never know it existed. But under the
sod, between the quince bush and big apple tree, is a wedge
of well-broken-in sand waiting to be uncovered and topped
up for grandchildren, if and when. They'll find a small
fortune in lost Star Wars figurines buried there
if they dig deep enough.
Size and Shape
To determine the size pit you need, wait till your kids get
down on their hands and knees—head-to-head, playing
together with little cars, model animals, or small dolls.
You'll see that two children establish a more or less
target-shaped play space: a one-to-three-foot-diameter
joint-play circle inside a larger maneuvering circle from
four to five feet in diameter. Three children need perhaps
six inches more in circle diameter, and four a bit more
still. Surrounding the active play space is a ring of floor
space where they will keep toys not in active use.
Our sandpit was built when Sam and Martha were two and four
years old and requiring constant supervision, so it had to
be placed in eye-shot of the kitchen and sun room windows.
The best location on our place was in the lawn, just a few
steps from the kitchen porch and shaded at midday by a
spreading apple tree—an important consideration now
that we know how full sun can do serious damage to fair
skin.
When the excavation was a foot deep, I encountered a huge
apple-tree root that was too big to be grubbed out easily
and large enough that I felt the tree needed it more than
we need a perfectly round sandpit. So I ended up digging
out a kind of peanut shape, a little less than a yard wide
and some five feet long. As I watched the kids play in it
over the years, I decided that the tree root had put me
onto the ideal sandpit shape. The curved oval offered
adequately separated independent-play spaces at each end,
joint play space in the middle, and a racetrack all around.
Once site, size, and shape are decided, you need to dig the
pit, assuring that it will hold shape and drain quickly.
Cut out sod in easily moved chunks. You can plug good sod
into bare spots in the lawn, or stack it upside-down to
molder into the compost. Do not just dump the sod in a
split-donut-shaped rim around the pit thinking it will
reduce the digging needed, and help keep sand in. I
followed that reasoning and can attest that it is
impossible to mow the grass on the round hump without
scalping the top and stalling the mower. If you do want to
rim the pit with sod, pack a sloping fillet of thin sod
chunks or top soil around the outer edge to form a gently
sloping volcano shape that can be mowed easily.
Dig out the dark-colored top soil and add to compost or
scatter in the garden. If it is as good as was the loamy
soil under our apple tree, screen out rocks and mix with
compost for potting soil. When you get to light-colored
subsoil, you may need a square-ended cutting spade or even
a mattock or pick to remove it ...but do dig till you get
down 18 inches, and two feet is better to let the kids dig
really satisfying pits and tunnels.
If your subsoil is hardpan or clay, the pit may not drain
well, and stagnant water can make the sand smell like a
swamp. If the sand pit is on a slope, dig a narrow trench
out from the pit bottom in a slight down angle till it
exits the brow of the hill. Put in perforated drainage pipe
or drain tile or fill with crushed rock or coarse gravel,
cover with a layer of plastic sheeting, and replace soil
and sod. Or, in the center of the pit, use a posthole
digger to grub out a dry well a foot across and as deep as
you can reach, and fill with rubble, stones, or crushed
rock.
Rim the pit cleanly by digging an undercut around the
rim—scraping about six inches of soil out from under
the sod all around. Especially if soil is wet, loose, or
sandy, set corrugated metal or plastic lawn edging in under
the sod all around the cut to keep the edge from subsiding,
and letting topsoil intrude into the sand wedge. The edging
will also bar soil critters from moving in and will slow
the inevitable mingling of soil with sand. Don't run the
edging up to ground level, as the sharp edge could cut a
child; push the ring of sod jutting beyond the undercut
down over the edging to form a rounded lip at the pit's
edge. The mower won't reach down, but the kids will keep
grass around the lip worn down.
A SANDBOX
If you do not want to dig up your lawn, boxing the sand
above ground is fine, although the grass under it will be
killed unless you make the considerable effort to move box
and contents every few days.
You can make a simple but serviceable wooden sandbox from a
sheet of 1/2" thick plywood for the box and a cheaper 1/4
sheet for a base. Cut one 4' x 8' sheet into three 16" x 8'
strips (see illustration above). Bisect one strip into a
pair of 4' lengths. Form the four panels into a 4' x 8' x
16"-high rectangular open-topped box (make it shorter if
you wish by trimming the long panels equally).
Fasten 2" long wood-lath stakes at ends and every two feet
along the outsides of plywood panels, and hammer stake ends
into the soil to hold the panels down. Fasten the
galvanized-steel right-angle truss plates you bought from
the hardware store inside each corner—running
self-tapping drywall screws through holes in plates
...through ply panels ...and into end stakes.
Make triangular corner seats with scrap wood cleats
fastened underneath to fit the edges of the plywood sides.
Glue and nail the seats to the ply and corner stakes, and
sand the seat—the edge facing into the box
especially. Finish seat and box with paint or outdoor
varnish to bind in any potential splinters.
As an additional antisplinter measure, around the upper
edge of all four sides, fasten wood molding or plastic
bumper material from a boating-supply store (or collect
three or four old bicycle tires; cut in half, snip
sidewalls every few inches and staple around ply). You can
install the sides around a second sheet of ply (with an
inch trimmed off one end and one side) laid on the ground
if you want to be able to shovel out the sand easily. There
is little point of fastening bottom to sides.
Be sure you use outdoor-glued plywood that is smooth and
splinter free, "finished-one-side" for the upper surface of
the bottom sheet and inner surface of the sides—where
kids will scoot around and might get splinters. Before
beginning construction it is best to seal both side surface
of plywood with a clear, weatherproofing finish to bind in
splinters and retard decay.
A WOOD-BEAM SAND CRIB
I've built plenty of plywood boxes, however never to hold
sand. The one time I did build soil bins above ground was
to contain compost mixed with glass cullet made by crushing
old bottles (this was in 1969—just before the first
Earth Day when municipal recycling began to catch on). I
used it to grow lovely, straight carrots, but the design
would make a sturdy, quick, and easily
disassembled/recycled sandbox.
The carrot crib was made of stacked 8"-square, 8'-long
fence posts sawed from native Northern white
cedar—which (along with redwood and red cedar in the
West, Osage orange in the Midwest, and others) just
naturally resists the terrors of bugs and rot. Cheaper is
pressure-treated lumber used in ground-contact
construction. However, the pressure-treatment contains
copper and arsenic, two metallic poisons that I didn't want
near the carrots and you surely won't want holding in your
kid's sand pile.
I notched the ends log-cabin—like with the chain saw
and stacked the posts three high on a flat and level area
of sod. Their weight held them in place, but they were
warped enough to wobble, so for good measure, I drilled
3/8" holes down through the corner joints and dropped in 6"
spikes as lock pins.
To get sand, I recruited an assortment of kids and made
them sit quietly in the pickup truck bed while we drove to
a natural gravel and sand bank. After the kids chose the
best sand in the hill, we all started shoveling it into
buckets and dumping it in the truck. We picked out roots
and clumps of sod and rocks large enough to do damage in
small hands. Back home after a stop at the swimming hole,
we dumped the larger rocks into the dry well I'd sunk in
the center of the pit, then shoveled in the sand. It took
three loads—wet sand and a half-dozen wet, bouncy
kids being heavy enough that a third-of-a-yard (9 cubic
feet) made the truck's rear springs complain a little.
If you don't have a truck, but live near a natural sand
deposit, you can haul it buckets at a time in the trunk of
a car. You may be able to get road sand from your town's
landfill or highway department. Or, you can order it hauled
in a dump truck from any aggregate or traprock supplier to
the building trades. Clean "sharp" sand will be stone and
dirt free. Or as a last resort, intown pool and outdoor
furniture retailers sell white beach sand in bags for city
kids who need sandboxes as much or more than country kids.
Cats
The neighborhood cats may try to adopt a sand pile as a
giant kitty-litter box. Don't let it start. Besides being
anaesthetic in the extreme, cat feces may contain human
pathogens and parasites and you surely don't want the kids
playing anywhere near it. Our dogs woofed cats out of the
yard during the day and the kid's green-eyed, orange
she-cat chased them away at night—and, once she'd
joined the kids playing in the sand a couple of times, she
seemed to prefer the loose soil of our garden to the sand
pit. But, I kept a constant check on cat activity. On the
way in from the garden every evening, I'd smooth the sand
with the garden rake. If I'd ever seen signs of a digging
or romping cat, I'd have raked and hosed the sand clean and
put on a cover.
The best sand cover I know is one of those inexpensive
blue, woven vinyl tarps you can get for a few dollars at
any hardware store. Leave one over the sand anytime it's
not in use, holding it in place with stones all around or
wood planks on top. The kids will be able to remove it and
(if you nag them long enough) replace it. If rain water
pools on top, burn a few small holes through the middle
with a small flame or soldering iron. (The heat will seal
the edges so the hole margin won't ravel and enlarge with
use.)
AN OUTDOOR WATER TABLE
If you've visited a kindergarten recently, you've seen the
children playing in an indoor water table: a sturdy
worktable with a low rim around the perimeter to hold a
very shallow pool of water. At an indoor table, children
must be disciplined to create quiet little water worlds.
Outdoors, play will be more rambunctious, so water can be a
little deeper and bathing suits are the garment of choice.
We always provided a supply of little disposable
bathroom-size paper cups for pouring—otherwise, a
succession of cooking measures, coffee mugs, and dangerous
glass drinking vessels found their way out to the table.
Size and Depth
Most school water tables are built to be kid-waist high,
but for a backyard version you needn't build a piece of
furniture with a rigid frame and legs. Build it on flat
ground and block it to be perfectly level so the kids can
play in it much as they play in the sandbox, and you'll
save time, trouble and weight (filled with sand or gravel,
rocks, and water, it will be heavy enough.)
Like the sand pit, the table should be long enough to
present an independent play area at each end but be narrow
enough that children ranged along opposing sides can reach
in and play together. Again, observe a pair of kids playing
dolls or cars on the rug and measure the distance from the
belt of one to the other. I've found that a 2' x 4' table
is fine for small kids, 2 1/2 x 6' good for older ones. Do
not be tempted to make it so big the children are tempted
to climb in, splash around, and bust it up.
If small kids have (even forbidden) access to a hose, they
will eventually fill the water table to brimming. And
despite being told not to, they will eventually go wading
in it. A small child could conceivably slip, fall ...and a
toddler can drown in even an inch of water. Unless you will
have an adult in constant attendance, don't give them the
chance to come to grief. If your youngest is under age 3,
build a table with a low rim or drill drain holes all
around so water can never get more than an inch deep. If
the youngest is over age 6, water can be up to 4" deep.
However, the table isn't meant to be a pool, but a
miniworld with shallow, playoceans and rivers. I think that
a box with 3" sides containing an inch or so of gravel and
drain-hole drilled to give a maximum standing-water depth
of 2" is best. The kids can have fun and you needn't worry.
You can block up one end a couple of inches to give a
shallow and deep end and enough slope to make little rivers
through the gravel or sand when the hose is left on in a
trickle. Kids can use wood blocks to dam the stream in
3"-deep pools to give a most satisfying, little waterfall.
BUILD A 2 1/2'-WIDE x 5'-LONG x 4"—DEEP WATER
TABLE
You will need:
Tools
Electric circular saw with plywood-cutting blade; Electric
drill/screw driver with Phillips-head drive bit and 1/16"
drill bit; Long, measuring steel and pencil, or chalk and
string snap line; Hammer and nail set; Caulking gun with 1
tube of outdoor-grade construction cement for wood, and 1
tube of (waterproof) adhesive, clear acrylic caulk; Sanding
block or electric sander and sandpaper; Staple gun and 3/8"
stainless steel staples (for sheet-good waterproofing).
Materials
One 4' x 8' sheet of 1/2"-thick outdoor-glued plywood
(smooth-one-side); Four 2' x 3' x 8' clear fir or spruce
wall studs (straight in all dimensions); Fifty 1 1/2" long,
#8 stainless-steel Phillips-head drywall screws; Twenty 1"
long, #8 stainless-steel Phillips-head drywall screws;
Twenty 3" galvanized finish nails; Twenty 1" galvanized
finish nails; Paint or clear finish; 20' marine rubber
bumper stock (or 4 or 5 old bicycle tires).
Construction
General assembly notes:
a. With 1/16 " drill bit, drill pilot holes
through plywood to start all nail and screw holes. b. Apply
a bead of construction cement in all wood joints.
Steps:
1. Cut ply into:
One 5' 4" x 2' 6" wide bottom panel; Two 5' 4" x 6" wide
side panels; Two 2', 6" x 6" wide end panels; Eight 6"
triangles for corner gussets.
2. Cut framing from 2" x 3" studs, the sides first.
Lay the bottom panel on the ground and cut two lengths of
2" x 3" to be as long as it is. These will be the sides of
the frame.
3. Fasten side-frame boards to the plywood bottom panel.
With smooth, finished face of the bottom ply facing up, set
a 2" x 3" frame side board under each long edge, the 2" x
3"s "on edge"—with wider 3" surface facing out. Be
sure outer edges of frame boards are even with edges of the
bottom sheet. Fasten with screws 6" from end and placed
every 6' ; screws will be through ply and down into the 2"
x 3"s.
4. Cut frame ends and cross braces to fit bottom panel.
Turn bottom panel over. Measure and cut 2" x 3"s to fit
between ends of the frame boards just screwed on. Measure
and cut 5 other lengths of 2 x 3 to form a ladder shape of
cross braces between frame sides.
5. Tack fasten ends and braces. Arrange frame ends and
cross braces in a ladder shape on underside of bottom
panel. Cement and tack in place with long, easily removed
nails through 2" x 3"s and into ply.
6. Reinforce underside of corners. Cut four triangular
braces from scrap ply and place one at each corner. Use
cement and short finish nails to fasten.
7. Carefully turn ply over again. Set screws through bottom
panel and down to the frame members, screws about every 6".
Now the bottom is framed.
8. Next, "box in" framed bottom with plywood side and end
panels. Lay out the 5' 4" plywood side panels along the
framed bottom, lower edge of side panels even with bottom
edge of frame.
9. Lay out the plywood end panels. Arrange and (as needed)
trim ends of sides and ends so all corners meet in a butt
joint (end of one meets side edge of the other). Fasten
sides and ends to frame with screws 6" apart, 1/2" up from
lower edge. Remove tack nails from underside.
10. Cut and install corner cleats to strengthen up side of
corners. Trim about a foot of scrap 2" x 3" to be a 1/2"
square. Measuring in the box, cut four approx. 3"
cleats—one to fit into each corner, upper end even
with the rim. Drill stag gered holes 3" in from corners and
fasten cleats with glue and 1" screws through ply into
cleats.
11. Caulk and water seal the box. See below.
12. Install triangular top corner braces: Apply glue to
bottom of remaining four plywood triangles and tack one at
each corner of box, edges even with outside of box. Use
small nails through triangle and into edges of plywood side
and side panels and a long nail down into corner cleat.
Countersink nails well into ply. Sand edges. Caulk all
joints inside and out and water seal the plywood.
Waterproofing
The table needn't be completely waterproof, but it makes
for a better job, dryer kids, and less water waste if it
is. Here are three options:
A good bead of sticky, clear acrylic caulk along insides of
all seams will seal a well-fastened water table if wood
surfaces to be caulked are dry and dust free. But, under
repeated soakings, the caulk will work loose and plywood
will deteriorate unless covered with a waterproof finish.
Better is to caulk and then paint with clear outdoor
varnish or several applications of sky blue, glossy,
latex-enamel paint intended for house trim.
Better yet is the old way of sealing canoes and covering
aircraft. Get ahold of enough lightweight canvas, blue
denim, or any open weave, hard-finished fabric to cover the
sides and bottom, plus a gallon or two of marine (canoe)
paint or airplane dope. Sky blue is the best color. Cut
fabric into panels to fit bottom and all sides with a good
inch of overlap at seams and over the top of side and end
panels. Along bound edges of the fabric, snip off enough 2"
wide fabric tape to place over seams. Double-over cut edges
and staple edges of fabric panels to the wood, mugging well
and stapling into corners and pulling fabric over flat
areas as tight as you can. Then apply successive coats of
paint (under the second coat put painting tape over seams)
till you have a smooth surface. Let the children help paint
too; they love it, and modern latex enamels wash off little
hands and out of clothes so long as you don't let them dry
hard.
You can do a more modern job by replacing the fabric with
more costly, but vastly stronger, fiberglass mat and
replacing canoe paint with two-part epoxy
resin—obtainable with directions at any
boating-supply house. The resin comes in two parts; mixed
together and with color added, it is applied over the
fiberglass just as paint goes over cloth and will make a
glossy minipool. (DO NOT let small kids help apply the
resin, which is caustic and emits vinegary fumes till
cured.)
Land Medium
Kids need something to make land out of. Sod looks good for
a few minutes but quickly becomes sodden and gets the water
muddy. Crushed rock is arguably the best, as its corners
and many angular faces help it stay put better in water
than sand or gravel. The heavier pebbles in gravel make
more stable land areas under water than sand. Kids will
bring in rocks, clumps of sod, grass and leaves, and who
knows what all else, and the table can look a proper mess
at the end of a day's play. It is easy to move gravel
around under water with the hose to wash out peanut butter
sandwich leavings, while fine sand grains will compact and
hold trash.
Unless you want to enforce schooltype discipline, the kids
will splash and throw water. Crushed rock or gravel will
stay put on the bottom while sand will splash out with the
water, to get into silky young hair and small eyes.
Crushed rock and washed gravel are available from any
aggregate-supply outlet. You won't want a dump truck full
and you can buy it in bags, or you can get crushed marble
and other decorative rock at most large nurseries. For a
small table, you might find it easiest to buy
fish-tank-bottom gravel from the pet store. The cheapest is
natural stone, though the kids love to mix up a variety of
virulent neon colors that hurt my eyes. Adding a new bag of
a fresh color once in a while will enliven a slow
afternoon.
Moving Water
Remember when you were a kid, how fascinating it was to
play in a little stream? You could dam it up, float sticks
down it, and imagine you were Tom Sawyer rafting the
Mississippi. Block up one end of the water table an inch or
two, with shorter supports every few inches downhill, hold
the end of the garden hose in one corner with a brick, and
leave the water on in a small flow. Let the overflow run
over at the other end or drill drain holes to control water
level. Experiment so water flow is strong enough to flow
through but not so strong it erodes "land" areas. If it is
the dry season, you can conserve water by running the
overflow to your garden or permanent plantings.
You can attach elaborate faucets and drain cocks, but they
just add weight. And you'll want td be able to move the
table each day, lest the lawn under it become a swamp. A 1
1/2" hole in the bottom with a sink drain plug will ease
emptying. A pair of 2" x 3"s with ends cut in an up angle
and screwed to the bottom of the table, with a rope loop at
one end, will make one-parent moving easier.
TOYS FOR SAND & WATER
Sand and water are fluid materials that kids will configure
as their imaginations dictate. But, if castle walls,
riverside piers, or Matchbox-car garages are to be much
more than humps in the sand, young builders need something
rigid to form or reinforce walls, platforms, and roofs.
Plus, the children need mobile toys to carry their
imaginations through the formed media.
Long, narrow wooden blocks are better for reinforcing sand
castles than conventional squares and rectangles. Wooden
wheeled excavators and trucks are good to move the sand
around. Plus, they will float to serve as boats, barges,
bridges, and rafts on the water table.
I made blocks and toy sand movers from woodshop scraps:
hardwood left over from furniture projects and softwood
from building-materials cutoffs. You'll have a few feet of
2" x 3" and plywood left over from making the water table.
If you don't have a shop of your own, see if you can
salvage leftovers from a local lumber finisher, a
commercial furniture maker, or a neighborhood woodworker.
Check building sites for ends of 2-by framing lumber and
other scrap. You might see if local hardware stores,
supermarkets, outdoor sports, or camping goods outlets, or
roadside stands sell wood stove or vacation camp fire
kindling. Stores near me sell plastic-wrapped packages of
assorted factory scrap hardwood for $3.00—expensive
to start a fire, but far less than you'd pay for the
equivalent board-footage of raw building stock.
Or, buy a few lengths of good clear 2" x 3" or 2" x 2"
lumber, some 4/5" x 4" decking-board stock, and several
feet of square, round, slat, and L-shaped hard pine or
poplar trim stock, and saw it to length. I have an electric
cutoff/miter saw that produces square ends automatically
and quickly. You can get the same result at less cost with
an inexpensive plastic miter box and muscle-powered
backsaw.
Sand-Building Blocks
To prevent splinters, choose closegrained, well-dried wood
that is hard enough your thumbnail can't make much of a
dent in it. For sand-pit play, cut any size board from a 2"
x 4" stud to 1/2" x 2" wood lath or 1 1/2"- or 2"-diameter
dowel into 4", 6", and 8" lengths. Much smaller blocks
disappear in sand. Larger blocks are out of sand-castle
scale and too easily become kid weapons when the inevitable
squabbles erupt. Sand all blocks well, especially ends
rough-cut across the grain. At minimum, seal with a coat or
two of deck sealer. For more elaborate finish options, see
below.
Strips of plywood will be used to make roads, roofs of
buildings, and walls. Make up a bunch—4" wide and 6",
8", and 10" long. Raw plywood will warp and delaminate in
the weather, so soak it well in a hard finish.
SAND TOYS
I made up a bunch of simple earth movers. Each design
illustrated represents a different combination of
construction options that you can mix and match in designs
you or kids make yourselves.
Bodies were made from 2" x 4" or 2" x 3" softwood or by
gluing and clamping strips of hardwood or plywood scrap and
sanding so joints largely disappear. I used Titebond
waterproof glue, a "space-age" indoor/outdoor wood adhesive
that requires no mixing as does epoxy.
Using a Forstner bit that produces straight-sided,
flat-bottomed holes, I drilled bodies to accept those
little round "peoples" that come with several brands of
wheeled toys ...or you can turn your own if you have a
lathe.
You can also make your own wheels on a lathe, or using a
circle cutter on a drill press or a hole saw on your
portable drill. Ready-made wheels in several designs and
sizes are available at craft and hobby stores or from the
mail-order catalogs that advertise in woodworking
magazines.
Between painted or varnished bodies and wheels, I inserted
enough fiber washers to prevent rubbing.
The following are brief explanations of how to piece
together a few models (see illustrations on page 54), but
there's room for versatility of design, so feel free.
Pusher The body of this minidozer is made
from a block of 2" x 3" building stud, the blade from
1/2"-thick hardwood. Three sets of wood wheels are fastened
with waterproof wood glue to 3/8 dowel axles. Axles are set
into grooves carved into under-body and held on by a
hardwood strip fastened with rustproof wood screws. No
drilling (or drill) required, and easy to make and repair.
Finish is minimal and intentionally rough: two coats of
deck-sealer (sanding between), to accept a child's crayons
or marker, yet clean off reasonably well.
Scooper Joints are screwed and glued
except for the scoop, which is made from thin, oak
box-making stock (or plywood) and joined with dovetails
made by eye with a coping saw with fine blade and a
1/4"blade hand chisel (easier than you think—try it;
just keep the chisel razor sharp). For strength, hardwood
fillets (from the flying model or doll-making section of a
craftsupplies store) are glued at inside corners of scoop.
The wheels are held on by 3/8" wheel pegs glued into 3/8
holes drilled in the body. Gives the best-finished look,
but the peg axle is relatively fragile and difficult to
repair. To show off the joinery, parts are stained with
contrasting colors, glued sparingly, filled, and
spray-varnished to a craft-store shine.
Hauler Made with a 2"-3" softwood body
with plywood base/bed. Wood wheels of this flatbed truck
are held on with short 1/8"-shanked brass wood screws set
into pilot holes drilled into hard dowel plugs that have
been glued into holes into the softwood truck body. Be sure
to use screws with round heads, as tops of flathead screws
have sharp edges. Parts were filled and painted before
final assembly, then, were given a several coats of clear.
Roller Body is made of three strips cut
from a 916" x 2" strip of white oak scrap, notched to
accept wheels, and laminated together with glue and brass
wood screws. The fat, turned-maple wheels are attached with
3/8" wooden wheel pegs. The example pictured was left
natural, filled, sanded, and sprayed with several coats of
clear acrylic to produce a craft-store finish.
Finishing
Most children have to be discouraged from marking or
coloring on toys—especially on smooth, carefully
varnished, inside-use wood blocks and rolling toys. Our
blocks are for outdoors, however, and I find that kids
adore being allowed, even encouraged, to use crayons,
markers, or paints to turn the building blocks into girders
(or magic wands) ...and to draw spokes and mufflers (or a
flowered border) on the wheeled earth-moving toys.
Probably most satisfactory to most young children is for
you to soak the wood in a colorless outdoor sealer (made
for decks), and let the children do a quick finish sanding
and then decorate with water paints, crayons, or washable
markers. The colors will wear off quickly, and I've found
that the kids will get the urge to redecorate several times
over a summer.
Some kids—mainly boys aged 6 to 8 who are future high
school Wheelheads—love vehicles with wheels that
leave aggressive-looking tread marks in moist sand. You can
give your tread-maker a narrowedged wood file and let him
make grooves or notches or crosses in the wheels of his
favorite sand vehicle to leave personalized "treads." Black
marker will give tires a satisfying color.
Exposed to a summer of sun and rain, unfinished wood will
weather to a mottled gray that isn't very attractive to an
adult eye, but doesn't seem to reduce play value to the
kids. Bring the blocks and toys in come fall, hose off the
sand, bleach with diluted Chlorox or a wood bleach, and
store till next winter—when you and the children can
refurbish them.
Refinishing or rebuilding the sand toys can be a powerful
hint of warm weather to come and become a late-winter
family ritual much like carving pumpkins on Halloween. Our
kids would get all excited, bundle up in snowsuits and
boots, take the wooden toys out to the sandpit (still
buried under a yard of snow), play with them in the snow
for a while, andof course-leave them buried there. So long
as we kept the dogs from carrying the good-chewing wood
blocks off, building blocks and sand movers would sink as
snow melted and be in place and ready to excavate when the
weather warmed in the spring.
A few fastidious young ones and many older kids who are
developing a precocious sense of order will resist marking
on toys or having toys that look "dirty." For them—or
to satisfy your own sense of order—you can give the
blocks and toys a better finish. Easiest is to assemble
toys, then preserve the wood in one step with several coats
of outdoor wood preserving sealer/stain. For a better job,
before assembling, sand the wood smooth—slightly,
rounding only those sharp corners that will be exposed
after assembly. Treat exposed faces with several coats of a
good sanding sealer (sanding lightly between coats). Spray
parts with several coats of nontoxic exterior-grade enamel,
truck bodies in bright colors, and wheels in black or
bright with black tires. Assemble and then, for a toy-store
finish, spray with thin coats of clear outdoor acrylic
finish.
