Bachmann 'Peak': Springs, Bogie
Assembly and Rolling Test
Locate the Inner Primary Spring assemblies,
which you soldered up earlier.
Cut four further lengths of the primary
spring wire (.016"), each 29mm long.
Cut two lengths of the thin (.008") steel wire, each 20mm long, and make a 90° bend
in each one, 5mm from the end. These are the retaining wires for the radial trucks.
Cut eight lengths of the secondary spring wire (.019"), each 38mm long.
Find a block of material long enough to
support the bogie subframe, deep and
narrow enough to allow the wheelsets to drop
all the way down in their slots.
We use this tufnol jig for wheeling up and
other assembly work. It allows the whole
bogie to be turned round without disturbing
any of the parts.
Place the subframe on to the block, and fit
the central and inner wheelsets into their
slots.
Orientate the inner primary springs with the
slots in their Splints towards the inner end
of the bogie, and fit them through the holes in
the tops of the Bearing Carriers. It's easiest to
do this with the Splints upside down to start
with, as shown.
