Make the pier tops A2(7) longer with 6
pillar parts from bag F. Then assem-
ble the 6 pillar parts from bag G and
join the two piers with them (directly
below the joint A2(3) - A2 (4)
(illustration 2).
illustration 2
Take care that the piers are parallel to
each other and that the glue can dry
while the piers lie on an even under-
lay.
Take the two pillar parts E1(1) and
the two segment holders E1(2) from
bag E1. Apply glue on the backside of
the segment holders and clip them
into the holes of the pillar parts. Then
adjust them (right angle).
Now (after sticking the parts together
without glue and the marking of the
parts with a pencil from bag F1) you
can glue both piller bottom parts.
Make both pillar parts E1 (1) longer
with 2 pillar parts F7-F8. Then glue 4
similar pillars together with the parts
from bag F1. The two remaining bot-
tom plates F1(6) should be stick as
closing parts under the two pillars with
the segment holders. Now you can
glue 3 pillar parts together, one pillar
F1 to the right and one to the left be-
side the two pillar parts F with the
segment holders. It is very important
to glue all plastic parts well together
and to let them dry 24 hours. Lay all
parts on an even surface (e. g. glass),
and check their positions.
If it is necessary to make the bridge
shorter, you should shorten the road-
ways, the stringboard bridge bases
and the underside bridge bases by the
same size from the bridge ends be-
fore assembly.

Now you have enough time to as-
semble the bridge base. Take the two
top side bridge bases (500 x 145
mm), apply glue on the short sides
and glue the two bridge bases to-
gether on an even underlay making a
1m long bridge base. (illustration 3).
Also this glued part should dry 24
hours..

Then glue on all bridge caps with
contact glue. Begin with the 4 narrow
cap sections and the 4 notched caps
from bag E1 on both sides of the mid-
dle of the bridge base. On the sides
glue on the bridge caps from the bags
J until the bridge ends.
After you have glued on all bridge
caps you have to drill the holes for the
rope. For this purpose you need a
2,5 mm drill. First mark the holes on
the upper side of the bridge caps,
closely to the upright standing inside
edge.
Calculate the distances from the
middle of the bridge evenly in both
directions. Begin with the first hole at
3,5 cm. The next 4 holes are positio-
ned each 6 cm from each other.
(illustration 4).
Attention:
When drilling the holes
keep the drill sloping outwards in or-
der not to touch the stringboard bridge
bases. (illustration 5).

Now turn the top side bridge base
upside down (bottom side upwards).
Now we glue the stringboard bridge
bases. Begin in the middle of the
bridge again. First mark the middle of
the two 500 x 15 mm stringboard
bridge bases. Now apply white glue
on one longitudinal edge, line up the
middle marking to the middle of the
bridge and place the stringboard
bridge base on the bottom side of the
top side bridge base, directly at the
sides of the bridge caps.
Place the two short stringboard bridge
bases in the same way to the right
and to the left of the middle part. Do
the same on the other side.
To support the stringboard bridge
bases you have to glue on the glue
aids. They should prevent that the
stringboard bridge bases snap.
(illustration 6).

Place one glue aid in the middle, glue
aids on the joints and at the ends of
the stringboard bridge bases (on both
sides). The remaining glue aids will be
glued on the free places on the sus-
