1-1/2", set at a proper angle to prevent board from becoming loose.
Hooks are about 1-1/4" long.

THE SWINGING ROPE

UPRIGHT--3" x 3" x 6'-9".

TOP PIECE--3" x 3" x 2'-9".

Upright and top piece are mortised or halved and bolted together.

Bracing at top (3" x 3" x 20-1/2" at long point of mitre cuts) is
nailed to top piece and upright at an angle of about 45 degrees.

Upright rests on a base measuring 3'-0". This is mortised together
and braced with 2" x 3" material about 20" long, set at an angle of
about 60 degrees.

Unless there are facilities for bracing at the top, as shown in the
cut, the upright should be made longer and buried about 3' in the
ground.

The swinging rope (3/4" dia.) passes through a hole bored in the top
piece and held in place by a knot. Successive knots tied 8" to 9"
apart and a big knot at the bottom make swinging easier for little
folks.

[Illustration: THE TRAPEZE.]*

THE TRAPEZE

TWO UPRIGHTS--3" x 3" x 6'-10".

TOP PIECE--3" x 3" x 2'-10".

Ends of top piece secured to uprights by being mortised or halved
and bolted together.

Uprights rest on bases of 2" x 3" material, 3'-7" long, connected by
a small platform in the form of an H.

Bases and uprights are bolted to dogs or pieces of wood 2" x 4" x
5'-8" set in the ground about 3'-0".

Adjustable bar (round) 1-3/8" dia.

3 holes bored in each upright provide for the adjustable bar. The
first hole is 3'-0" above ground, the second 3'-5", the third
3'-10".

Swing bar (round), 1-3/8" dia., is 20" long. Should hang about 16"
below top piece.

2 holes 5/8" dia. bored in the top piece receive a continuous rope
attached to the swing bar by being knotted after passing through
holes (5/8" dia.) in each end of the bar.

[Illustration: THE LADDER AND SUPPORT.]*

THE LADDER AND SUPPORT

LADDER--14" x 10'-2"

Sides of 1-1/2" x 1/2" material

Rungs 1/4" dia. set 10-1/4" apart

At upper ends of the sides a u-shaped cut acts as a hook for
attaching the ladder to the cross bar of the support. These ends are
re-inforced with iron to prevent splitting.

SUPPORT--Height 4'-6". Spread of uprights at base 4'-2".

Uprights of 1-1/2" x 2-1/2" material are secured to a foot (1-1/2" x
4" x 20-1/2") with braces (11-1/2" x 2-1/2" x 12") set at an angle
of about 60 deg..

Tops of the two uprights are halved and
