Use Valence Spacing Aids (132-135) to get the position as
accurate as possible. Two of these are slightly longer and are
used in front of the valence bend but not before the frame
bend begins - i.e. over the cylinders.
You Are Here
Just as a summary, the picture shows the parts made so far. Its
time to start making this thing look like a steam engine.
The cab base should slide over the end of the chassis frames,
ensuring that ALL of the slot in the cab base is taken up. Place
the cab body and foot plates on top of this so that the rear tab
on the cab sides locates in the cab base as well as the hand
rails, it may be necessary to ease the front of the foot plates
over the rivets in the frame.
When satisfied this is square solder up.
Place the cab cupboards and solder both to the cab floor and
the cab side. Very little solder is needed here, they should be a
snug fit. The foot plate overlaps the rear buffer by about 0.5
mm which is the depth of the rivets!
Boiler
Note
The boiler will slide into the smoke box by about 5 mm. Note
that the half etch marks on the boiler must line up with the
firebox and smoke box.
Do not be tempted to solder the splashers to the boiler too
early. They should be an accurate fit if the footplate is straight.
Remove
Boiler (1)
from the fret and roll to shape with the
locating marks on the outside. The longitudinal ends should
meet exactly.
Remove
Boiler Front (2)
and
Boiler Rear (3)
from the fret and
solder into place. Check these are a good fit inside the boiler.
After removing Fire Box Support Aid (139) from the front of
the fire box check that it is a good fit. Make sure you are
finished with filing the Belpaire curve.
Fit Hand Rail Knobs (Qty 4 2 mm, two each side) once you are
satisfied with the fit. If you do it now you can solder from
inside the boiler and get a better joint.
At the same time fit a 2 mm Hand Rail Knob either side of the
fire box.
Note
For EM and for P4 where there is a lot of side play it will be
necessary to remove part of the boiler by grinding until the
wheel will not short on the boiler. The same ‘L’ section used for
the roof of the cab may also be used (see Part 30 in the chassis
section) between the splasher and the boiler, it was there on
the prototypes.
Smoke Box
Remove
Smoke Box frame (4)
from the fret and fold to shape.
Remove
Smoke Box (5)
from the fret and roll to shape
ensuring that it is a tight fit over the end of the boiler.
