10. Drill out the buffer bodies with a
2.1mm drill to take the cast buffer head/
shank. Hold the drill in a hand pin vice
(chuck) and grip the buffer body between
finger and thumb. Drill through the body
from each end so that the hole breaks
through in the middle. Use a little spot of
spit on the end of the drill and this will help
prevent the drill wandering in the white
metal and breaking through the side of the
buffer. Then fit shank through buffer body,
snip off some of the narrow end of the shank to leave just over 1mm from the step, and solder a
retaining collar onto the shank. Open up holes in buffer beam slightly and fit buffers.

9. Solder the brake blocks (parts 16) to the
brake hangers (parts 17) remembering to make
up L/H and R/H sets. Fix brake hangers into slots
on underside of coach body so that they are just
clear of the wheel tread. I find that a miniature
electrical crocodile clip is useful to hold the brake
hanger for this operation. Spring the brake yokes
(parts 18) between the brake hangers and solder
so that the inside one runs slightly up from the
horizontal and the outside one slightly down from
the horizontal. Link the outside yokes back to the
pull rod crank at the vee hangers with 0.7mm
brass wire. On the prototype coach there was
quite a complicated arrangement of rocking links
around the yokes that I don't bother to model.

11. Cosmetic screw coupling (parts 19). Solder both halves of each hook
together (you may wish to dress the hook with a flat file to achieve a more
prototypical profile) and if necessary round the slot so that the link will swing
freely and then using round-nosed pliers form the four links into U shapes. Dress
the tops of two links with a file so that they will pivot freely in the slot in the hooks.
Thread one of these links through the hook and spring the ends over the pegs on
the cast centre. Then fit the bottom link.
Pass the coupling hook through the slot in the buffer beam and retain it with a
length of spring wire. Polish the centre of this wire with emery cloth first so that
you can solder it to the coupling hook shank once you are happy that the buffers
spring freely.
Fit the cast vacuum brake pipes on the centreline of
the coach ends. Soldering at fixing bracket and buffer
beam.
Fold up ends of grab
handles (parts 20) and
reinforce folds with 60/40
solder. Solder into the two
holes (may require drilling
out) next to the doors. A
sliver of thin card between
may be helpful. Fit etched T
door handles into doors.
