 JUNIOR’S EARTH-MOVING and road-building
programs will be greatly extended with this toy
power shovel. Comfortably seated on the cab, he
pushes himself about and can swivel in any
direction. One control lever operates the boom,
another the shovel position, while a push rod
opens and closes the shovel. There’s also a winch
to use as a “stump puller,” and the cab opens
to store valuables.
Dummy traction treads are mounted on two
pairs of holders, each pair fitted with spacers.
The four pieces having rounded ends are stacked
and clamped together so axle holes can be drilled
in alignment. Two of these pieces are assembled
to a T-shaped crosspiece with waterproof glue
and screws. Then the spacers are glued and
nailed on and the two outside pieces are attached
similarly.
The cleated treads are made from two strips
of 3/8-in. white pine. Saw kerfs 5/16 in. deep, and
spaced 3/4 in., are cut across them. The strips are
soaked with water at points where they are to be
bent over the rounded ends of the tread holders.
The treads are cut out to fit around the ends of
the chassis crosspiece, and are attached with
waterproof glue and brads, two brads to each
cleat. Treads project 1/4 in. beyond the outer tread
holders.
Ends of the axles come almost flush with the
outer surface of the tread holders. Axles are
drilled for cotter pins, then slipped through one
tread holder, wheels and washers added, then
slipped through the other tread holder, after
which the cotter pins are installed. Use 5-in.
rubber-tired wheels which will project % in.
below the tread holders.
Dummy drive and bearing wheels for treads
can be made of cardboard (Bristol board) as
shown in the lower right detail on page 2342.
They are glued and bradded in place, later
painted and then coated with spar varnish to
seal out moisture. The bearing wheels also can
