Apply synthetic rubber adhesive to
the front sides of the piston valve
tail guides A. Insert the guides into
the holes on the rear cylinder plate,

It is always best to use as
small an amount of instant
adhesive as possible, but,
as it is a liquid adhesive, it
is easy to apply too much.
If this happens, you can
use some tissue twisted
to a point to soak up the
excess, as shown on the
right. You can also use a
cotton swab, but this will
lack the narrow tip that
the rolled tissue will have.
As superglue dries quickly,
you will need to act fast.
Before the adhesive
dries, place the assembly
on a at surface. Check
that the rod is vertical
from all directions.
Apply synthetic rubber
adhesive to the back
side of one of
the front cylinder
covers, avoiding the
circled hole.
Screw one of the safety valves
into the hole at the bottom of the
cylinder cover.
Hold the rod in position
and apply some instant
adhesive to the inside of
the housing.
Align the position of the
small hole with the one
in the cylinder plate.
Insert the centre of the
cover into the large hole
in the plate.
Repeat the process to t the other
cylinder cover and safety valve.
Allow the adhesive to
dry, then repeat this
process to assemble
the second set. Before the adhesive
dries look through the
small hole to ensure it
is aligned.
Apply some synthetic rubber
adhesive to the back of both
piston rod housings.
Place the housings onto the
projections in the centres of the
front cylinder covers (circled).

Prepare one of the
air valve wheels and
two hole covers.
Position the wheel
with the projections
at the arrowed
points when gluing
to the side plate.
Apply synthetic
rubber adhesive
to the back of the
wheel and glue
it into the circled
hole. Adjust the position of the wheel
so that the projections match
those shown above left.
Apply synthetic rubber
adhesive to the pins on the
backs of the hole covers and
place them into the circled
holes in the side plate.
Don’t let any
glue block
the holes
at the side of
the plate.
Align the side plate
assembly with the
left front and rear
cylinder plates.
Half-tighten a 2 ×
2mm screw into each
of the aligned holes
(circled).
Align the holes in the side
plate with those in the
cylinder plates.
Half-tighten another
two 2 × 2mm screws
into the two holes on
the underside (circled).
This shows the position
of the left side plate after
being tted.
At this point, the front or
rear cylinder covers may
not be ush with the
side plate, as is the case
in this picture.
Place the left
side of the model
on a soft cloth
or towel, and
then repeat the
process to t the
right side plate.
Tightening the screws fully
should close this gap.
Turn the side
plate over and
apply a small
amount of instant
adhesive to the
backs of the pins.

When steam is fed into the
cylinders, water can accumulate
in them due to condensation,
especially when operating
in the cold, which can cause
trouble in steam locomotives.
The drain pipes at the bottom
of the cylinders allow this
build-up of water to be
discharged from the
pressure system.
The drainage pipe under a
cylinder of a real C57. Here you can see a C57 underway with its
drainage pipes fully opened, discharging
the water from the cylinders.
The front end of
each drainage
pipe is thinner
than the rear.
Apply some
synthetic rubber
adhesive to the
three pins on one
of the pipes and
insert them into the
circled holes on the
underside of the left
side plate.
Fit the other drainage pipe
to the bottom of the right
side plate in the same way. Apply some instant
adhesive to the ends
of the three pins of the
pipes, to make them
more secure.

Apply some epoxy adhesive to one
end of one of the piston rods.
Push the rod in as far as it
will go, then wipe away any
excess adhesive.
Insert the piston rod into the hole in the
cylindrical projection of one of the crossheads.
Repeat with the second rod and
crosshead. Keep both assemblies
positioned with the rods vertical, as
shown, until the glue dries.
Keep the
crosshead parts
together.
The crosshead
FOCUS
The crosshead pin and crosshead on the real C57 are
secured using a hexagonal nut, just as on the model. When working with epoxy adhesive, make
sure to not move the parts you are gluing
until the epoxy is completely dry, because
the strength of the bond is weak when the
adhesive is still wet.

The rear underframes are mostly symmetrical, the
only exception being that when the underframes
