Bachmann 66: Springs, Bogie
Assembly and Rolling Test
Spring wire sizes are listed on the card
inserts that come with the kits.
Cut eight lengths of the primary spring wire,
each 30mm long.
Degrease the wires and apply, to one end
of each wire, a bead of fast setting epoxy
r e s i n about 1mm diameter, i.e. just large
enough to prevent the springs being pulled
through the holes in the ears of the central
bearing carriers. Put the springs to one side
while the resin sets.
Cut eight lengths of the secondary spring
wire, each 18mm long. At one end of each
wire, make a 90° bend 1.5mm from the end.
Return to the primary suspension wires and
check that the epoxy resin beads have set
hard.
Take four of the primary springs, one of the
central wheelsets, and insert one spring
through each of the four holes in the ears of
the bearing carriers, feeding them through until
retained by the epoxy beads.
Check that the epoxy beads do not restrict
the movement of the springs in the carrier. Reduce their length and/or diameter if
necessary (having only recently hardened, they will respond quite well to paring with a
sharp knife).
Take the inner and outer wheelsets, check
their correct orientation to the central
wheelset, and slide their bearing carriers on to
the primary springs.
