A razor saw may be used to make these
cuts. Take care that the moulding is
adequat ely supported while cutting - it's
helpful to have a solid block of material which
just fits between the sides of the moulding.
Give the drive unit assembly, including the
idler axle holes, a thorough wash and
degrease to remove all traces of swarf and
dust.
Reassembly
Refit the three idler gears and axles between the centre and outer axles, beneath the
worm.
The kit is designed to allow the model to be driven on all six axles, i.e. as a C- C,
corresponding to the Co- Co arrangement of the prototype. But you can avoid a
certain amount of complication by using the 4-wheel parts of the drive as they are and
assembling the loco as a B1-1B, in which configuration it will perform perfectly adequately
and retain much of its hauling capacity. If you wish to take this option, you can skip the
remaining steps in this section.
Remove the Drive Plate etches (D1, D2)
from the fret. Check that the 1.5mm dia
idler axles are a free fit through the holes in
t he plates (Note: one pair of holes is slightly
larger than the others). Fold up the spacers on
Plates D1.
