The following diagrams illustrate the left arm but the
same way applies to the right arm too.
Undo the string from the core and
cut in half. Tie one of the strings
to the A part at the shoulder joint
with the tweezers.
Make a loop at the
end of the string.
Do not dispose the core of the string because it can be used as a doll stand afterward.
Put the end of
the string through
the loop twice.
Pull the end of the string and tie.
Bring the knot close to the arm.
Make a knot first, then
bring it close to the arm.
Put the longer part of the string through the
hole B in the projection at the shoulder joint
and then through the hole C in the
projection at the armpit of the body.
Attach the arm to the body.
Snap it in so that the
projections fit in the holes.
Be careful so
that the string
isn't caught in
the shoulder.
Put the end of the string through the
projection with a hole at the shoulder joint.
There are two holes, so make sure the
string goes through the hole A first.
A
C
B
Back
Notice!
Trim off the shorter end of the string which doesn't go through
the holes B and C with scissors.
Check the motion after both arms are attached.
Check!
Check that the
sleeves don't touch
the shoulders and
both arms move
smoothly.
Put the string from the hole C through the hole
D and hole E in the side of the body. Then put
it through the hole F in the prop between the
knees and lastly put it through the hole G
twice and pull it down. (It makes one loop.)
Do the same thing with the other side.
Let's continue the stringing at the side of the body.
Cut the tube into 5mm. Put the string
coming from the hole G through the tube
and fix with a wedge. Do the same thing
with the other side.
Drive wedges.

Checking the Motion
98
Adjust the tension of the strings.
Front
Back
Bring the tubes near to the prop with
the arms staying at the position shown
in the figure 55..(The arms are down at
the front.)
Turn the body upside down. Bend
the legs until it comes to the position A
and then let go of them. If the legs go
back to the position B, the tension is
adequate.
When the legs doesn't go up to the position B
Hold the tube and pull the string to get higher tension.
When the legs go higher than the position B
If the legs go higher than the position B, loosen the tension as shown in the upper
diagram.
When the legs go higher than the position
B, that is, the tension of the string is too
strong; push the strings lightly with a
finger at the arrow part shown in the
diagram above and loosen the tension.
A
B
Push slowly.
Keep the hand closest to the body.
Stand the doll with the arms
down in front, and then
push back the doll softly.
The doll puts
hands on the
floor and does a
somersault.
It makes a landing with its
hands on the floor as shown
in the diagram below. It is
all right if a sequence of
motion goes smoothly.
Finale!
Unsuccessful Case 1: When the tension of the
string is too loose (or the string is too long), the
doll doesn't turn arms to the back and fall down
from the head.
Unsuccessful Case 2: When the tension of the
string is too tight (or the string is too short), the
doll doesn't do a somersault and stops halfway.
In either case, make adjustment again as 77
above.
When the check is
finished, cut the
strings with 20mm
margins. Also,
remove the head and
take out the balls.
Put three iron balls in the
body and set the head
and check the motion.
