Take
a look at the above drawing to familiarize yourself with
the hole positions of the dummy body.
Fitting
the arms to the dummy body.
Ensure that when the arm is fitted into the hole that the
there is movement, the arm hole should be around 4mm larger
than the arm shaft. e.g. Arm shaft 38mm square hole in body
42mm square.
Top arms
Place both the top arms into the arm holes at the top of the
dummy body, the shafts of these arms are of offset. The left
arm should be placed with the top of the shaft upright and
the right arm should be placed with the top of the shaft
facing downward (see pic below) This will ensure that the
arms are close to level when in place.
Push both arms from the front so that they are as far back
into the body as they will go.
when you have done this take a pencil and draw a line at the
top of each shaft at the back of the dummy. Ensure the line
is tight to the dummy body and the arms have not moved
forward when doing this. See drawing below
Now remove both the arms place them down with the
lines uppermost and measure back from this line 15
milimetres See
drawing below draw
another pencil line at this location.
Now find the centre of the shaft width (19mm in from side)
and make a cross at this location. This is where you will
drill the 12mm diameter hole for the locking pin. It is
worth making a punch mark at the centre of this mark using a
bradawl, centre punch or nail, this will stop the drill bit
wandering when you start to drill. If you have access to a
pillar or bench drill use this with a 12mm diameter drill
bit to drill the hole completely through the arm shaft. If
you are using an electric drill ensure that you have the
arms clamped in a vice or onto a bench. It helps to have a
scrap piece of wood underneath the arm shaft so that when
the drill bit comes through the shaft it does not break out
the timber. Once the arm shafts are drilled replace them in
the dummy body and drop in the locking pins and you are
ready to go.
Bottom arm
follow the same procedure as above, only the bottom
arm does not have an offset shaft so can be placed
into the dummy body any way around.
