lightly solder. This may be removed later once the assembly of
the fire box is finished.
If you wish to bulk up the inside of the fire box then remove
Fire Box Braces (51-54)
from the fret and insert into the inside
of the fire box using the same 0.45 mm wires to locate
securely and accurately - then solder up using lots of heat.
Now curve the splasher part of the cab front that fits over the
wheels to shape using the fire box as a guide, it is better that
this is slightly over-curved since it will be easier to solder in
place. Note also that the curve starts just below the
rectangular hole for the reversing lever. The half etch at the
bottom should just fit onto the footplate.
Locate the fire box into the front of the cab using the six slots
provided - take care that the fire box sits flush since it will be
difficult to adjust later.
Repeat this with the part of the fire box that fits inside the cab.
Remove Fire Box Cab (45)
and the second
Fire Box Support
(Aid 140).
There is only one tab which locates centrally at the
top.
Once the fire box is secure and square, solder can be run
round the various joints.
If you want to fit the Inspection Covers (46-50) (not always
fitted - see photographs) to the curved part of the fire box
then remove
Inspection Covers (46-50)
from the fret, curve to
shape and solder in place. These are fitted along the centre of
the curved part of the boiler and at 3 mm, 13 mm and 23 mm
from the front of the cab on the left and 8 mm and 20 mm
from the front of the cab on the right side. These have a
nominal spacing of 2’ 6”.
Add Washout Plugs (8) to both sides of the fire box.
Fitting Cab Front & Sides
Position the cab front
BETWEEN
the cab sides. The half etch
end on the end of the splasher will lie flat on the footplate.
Very lightly solder the top corners first to get the position
correct and then slowly complete the soldering around the
curve.
Front and Centre Splashers
Remove
Splasher Sides (20-23)
from the fret and solder onto
the footplate ensuring that the half etch representing the
brass trim is on the outside.
Remove
Splasher Tops (26-29)
from the fret, roll to shape so
that the half etch parts are on the inside of the curve, bending
over the half etch ends so they will lie flat on the footplate and
solder into place. Note that the splasher tops fit level with the
top of the Splasher Sides and
NOT
on top of them!
Note that the rear pair of the splashers should be trimmed so
that they fit between the Splasher Side and the Fire Box side
since they will not fit
under
the fire box side.
