2.4

Solder the drag beam (part 4) below the rear end of the footplate and to the valances.

2.5

Solder a nut to the top of the footplate at each of the chassis mounting points.

Section 3 Coupling Rods

3.1

The coupling rods are made from steel for maximum authenticity but they require very careful

cleaning after assembly as any trace of ﬂux (or indeed water) left on them is bound to cause

rust.

3.2

Each coupling rod is etched from a total of four parts as shown diagrammatically below. They

are designed to pivot about the centre crankpin to allow the movement necessary for a ﬂexible

chassis.

3.3

Solder each coupling rod outer to its inner aligning on either the front or rear crankpin holes as

appropriate. Note that the sections with two holes are the front outers and the rear inners. Each

section is single thickness at the centre crankpin boss (shown in grey below) and the simulated

knuckle is in the rear section of the rods.

3.4

Open out each crankpin hole until it is just a sliding ﬁt on the crankpin of the wheels you intend

to use.

Section 4 Locomotive Chassis

4.1

Remove the sideframes from the fret and decide which is to be the driven axle - this will be the

rear if you are following my recommendations Remove the sections around each of the other

axleholes along the half-etch lines in the following manner. Thread a piercing saw blade through

the slot between the "spring" and the frame, secure the top end of the blade and saw up the half-

etched line. It helps to keep the saw edge close to the end of the work bench at all times, and press

down hard on the frame with your ﬁngers. Keep the saw vertical and let the blade do the work

on every down stroke. Saw up to the top of the line only. Work the blade back to the spring end

and then saw across the top of the spring. Next saw up the other vertical. Release the blade and

remove it. Using a pair of pliers, push the sawn part back (folding it on the top half etched line)

and waggle it until it breaks off cleanly. If you are modelling a member of the 812 class remove

the centre spring completely.

4.2

Check that the ﬂexichas bearings can easily slide up and down in the sub-hornblocks. If not, gently

and carefully open the slots until this can be achieved. Take extreme care not to overdo this as a
