LNER/BR D49/4 THOMPSON REBUILD 'THE MORPETH' INSTRUCTIONS
CHASSIS ASSEMBLY
The chassis can be built rigid or compensated so decide now which one you are going to
make. If building a compensated chassis remove the sections from the front and rear axle
holes.
Take the frames (1) and solder the axle bearings (2) into the frames. Fold the chassis up and
solder the front and rear frame spacers (3) into their recesses. Solder the four 2mm bearings
(11) into the axle holes in the bogie (10). Fold the bogie sides down and solder the front and
rear spacers (12) into the slots.
COMPENSATION
Beam compensation requires a fixed
point, so that when the loco is on the
track it remains level. With this chassis
the fixed point is the bogie. Turn to the
compensating mechanism itself.
Solder the 1/8
th
axle bearings (2) into
the compensating beams (4). The
compensating spindle should be cut
from the brass wire (6). The beams
are held apart by the compensation
spring (5). It is very important that no
parts of this mechanism are soldered in a fixed position other than the spindle to the
