SECTION 1: BRIEF HISTORICAL DETAILS

In 1936, Gresley introduced what was for many his finest design, the V2 class 2-6-2 tender engines. Popularly known as the

‘Green Arrows’, the V2 class was originally intended for mixed traffic duties, especially the fast, brake–fitted, long distance,

goods and perishables trains. They quickly proved little inferior to the Pacifics on express passenger trains, and were

competent to tackle all except the streamlined schedules.

A total of 184 engines were built between 1936 and 1944 as follows:

Variations/Modifications incorporated into the kit

Valve guides: Nos. 4771-75 were fitted with a different design of front valve guide to the rest of the class.

Fall plate: The original arrangement was for a fixed extension to the cab platform to suit the fall plate, which was hinged on

the tender front plate. Starting with No. 4889 (built 8/1941) the fall plate was transferred to the cab platform and a wooden

platform was provided at the front of the tender for the fall plate to rest on. The existing engines were brought into line as

they passed through shops.

Cylinder wrappers: A circular access cover in the cylinder wrapper was fitted to all but the earliest engines.

Pony Truck: The engines were built with pony trucks incorporating Gresley’s patent double swing link suspension. Starting

with No. 884 (4855) in December 1946 the pony truck was replaced with a new design using spring side control. The whole

class was fitted with new pony trucks by April 1952.

Frame guard irons: The new pony trucks were longer necessitating the removal of the frame guard irons and the clipping

of the cylinder drain cock pipes to the front steps.

Lamp iron - smoke box door: two different types.

New cylinders and outside steam pipes: Between May 1956 & March 1962, 71 engines had the original monoblock

cylinder casting replaced with three separate cylinders and outside steam pipes.

Chimney: original type and double chimney with Kylchap cowls fitted to 60858/62/80/81, 60902/03 between October 1960

and November 1961.

TENDERS

As can be seen from the table the locomotives were fitted with three types of Group Standard 4200 gallon tender as follows:

Low front –flush side: New tenders of riveted construction with the join of the coping plate clearly visible.

Low front –flared top: Second hand tenders with stepped out coping plates.

High front –flush side: New tenders of riveted construction with the join of the coping plate clearly visible.

Tender changes were not uncommon so a dated photograph is needed to show the type of tender at a given time.

SECTION 2: CHASSIS DETAILS

Note that many of the components for both chassis and body are handed left/right and care must be taken to ensure the

correct component is used. I have not always identified left/right components separately but with care and common sense

no problems should arise.

Before construction can commence you have to decide which chassis you are going to construct. The options are:

Gauge 00, EM or P4.

Suspension Rigid, sprung, compensated.

Pickups

No pick-up material is provided. The options are:

Scrapers attached to printed circuit board fixed between the frames.

Plunger - drill out the 3 holes marked P on each side and fit according to the manufacturer’s instructions.

The 'American' system with the wheels on the loco shorted out on one side and the tender on the other. I have

produced some etched shorting strips, as an additional item, for this purpose. The drawbar between the loco and

tender can be used to carry the current.

SECTION 3: FRAMES

Having decided which chassis to construct you can now start construction by preparing the frames (parts F1 & F2). If you are

fitting the later spring pony truck then using the etched lines as a guide, reshape the front frame cut outs as shown in Fig. 2.

Then emboss, using photographs as a guide, the appropriate rivets.

For a rigid chassis open out the main axle holes to accept 1/8" top hat bearings (not provided) and solder them in place. If

you are going to fit sprung horn blocks, you should remove the axle holes by cutting up the half-etched lines, leaving a

standard 6mm wide slot and then follow the manufacturers’ instructions.

To construct the kit as designed with a compensated chassis. Remove the axle holes as described above. Carefully widen the

slot in the hornblocks (part 9) until the Flexichas bearings are a good fit. I find a significant variation in the bearings and once

I have fitted a hornblock to a bearing I mark the bearing and hornblock so that they can be later assembled together. A good

fit between hornblock and bearing is essential if the chassis is to run well.

Drill out holes C (1/16") for the compensation beams and holes B (0.45mm) for brake hanger pivots. Solder the rear

hornblocks to the inside of the frames aligning them with the half-etched line and with the bottom of the frames. Modify the

Flexichas bearings on the centre and rear axles as shown in Fig.4. Fold up the brackets for mounting the sandpipes for the

centre coupled wheels, as shown in Fig 3.

SECTION 4: FRAME STAYS AND ASSEMBLING THE CHASSIS

Remove parts F4, F5, F6, F7 & F8 to suit your chosen gauge. Open out the holes for the front compensation beam in part F7

to 1/16". Alter the shape of parts F4 & F8 as shown in Fig.3. Fold up parts F4, F7 & F8 making sure the etched fold line is on

the inside and that each bend is at a right angle.

Check that all tabs on the stays fit properly in their corresponding chassis slots so that the rest of the stay is hard up against

the inside of the frames. Tap the 10 BA holes in parts F7 & F8.

Now assemble the frames and stays. Start by tack soldering part F7 to both sides. Check that everything is square and that

the stays are hard against the frames. Put an axle (or better a longer piece of 1/8" rod) through the rear bearings and place

the chassis on a piece of graph paper to check that the axle is square to the frames. If all is well solder the remaining stays to

the frames checking constantly that the chassis is square and the frames are straight and checking that the rear of part F4

will be vertical. Stay F6 is not soldered in place until the angled plate and splashers have been attached.

For the original pony truck attach the pony truck wheel splashers (part F11), locating them in the frame cut outs, and the

guard irons (part F3).

SECTION 5: COUPLING RODS

The coupling rods are now made so that they can be used as a jig to align the remaining hornblocks accurately. First, drill out

all the crankpin holes to a convenient size which is well undersize for the crankpins. Drill out the fork joint holes 1.0mm so

that the 1.0mm nickel silver wire is a tight fit. Remove all burrs caused by the drilling. Now drill a hole, with the drill used for

the crankpin holes, in a small block of wood and leave the drill in the wood with its shank projecting. This projecting shank is

used as a mandrel to accurately align the laminations of each rod.

Place the laminates over the mandrel, and using plenty of solder and flux solder the two laminates together. You will now

have rods with the crankpin and fork joint holes aligned. Carefully file the edges so that the 'laminated' effect is lost and the

rods appear to be made from one piece of metal. The crankpin holes now need carefully opening out until they just fit, with

no free play, the ends of the hornblock alignment jigs (available from London Road Models or Markits).

The fork joints are now pinned using the 1.0mm nickel silver wire. Retain the pins, which should be a tight fit, by lightly

soldering on the inner face of the rods. The correctly assembled rods should now have a completely flush inner face.

SECTION 6: FITTING THE FLEXICHAS HORNBLOCKS

Prepare the remaining bearings and hornblocks as described in section 3 and slide them over the hornblock alignment jigs

with the springs between the bearings. Carefully compress the springs and clip the hornblocks between the frames and place

the prepared coupling rods over the ends of the jigs. Make sure the hornblocks are square to the chassis and that their

bottom edge aligns with the lower edge of the frames and then solder them in place.

SECTION 7: FITTING THE COMPENSATION BEAMS

Solder a piece of 1/32" steel wire through the holes in part F7 –see Fig.3. For the rear beams cut a piece of 1/16" brass rod

so that it fits through the holes C and is flush with the outside face of the chassis frames. Cut two equal pieces of 3/32" tube

which together fit between the frames and solder the rear beams (part F14) to them close to one end. Temporarily fit the

beams.

Temporarily fit all the wheels and axles and confirm that the compensation works properly and check that the chassis is

sitting level. The height of the top of the frames above the rails, over the rear compensation beam should be 23.4mm and

over the front compensation beam 25.9mm. Retain the beam pivot by carefully soldering one end to the frame.

SECTION 8: REAR FRAMES & RADIAL TRUCK

Fold in the radial truck hornguides on part F25 (Fig.7). Now make all the bends on part F25 - all 90oand with fold lines inside

- then solder in place on the rear of part F4 ensuring that the rear frame will be level. Emboss the rivets on the outer frames

(part F26) and form to fit. Fold up part F27 and locate between the rear frames. Check all is fitting correctly before soldering

the rear frames in place. Detail the rear frames as shown in Fig.7.

Bend part F36 to shape and solder around part F35 to make the lower firebox. Add the washout plugs at the corners from

0.5mm square wire and the blowdown tap (part BR6), before soldering in place on top of part F25. Add part F37 as shown in

Fig.7.

Fold up the spring wire bracket and side play stops on part F33. Fold up part F34 and attach part F33 and check for free, but

not sloppy, movement in the hornguides. Solder the small top hat bearings in place and fit the radial truck wheels using the

washers (part F40) to eliminate any side play. Bend up the spring wire to give some downward pressure and solder in place

through the bracket on part F25 and the hole in part F4. The radial truck is retained with lengths of 0.5mm square wire

soldered across the bottom of each horn guide.

SECTION 9: PONY TRUCK

Emboss all the frame rivets as shown in Fig.10. Solder guard irons (part P3) in place on the outside of the frames. Fold up

part P6 or part P10 and solder the appropriate stays in place as shown in Fig. 10. For the original pony truck form the dust

shields (part P8) to shape and solder in place. Solder parts P1 and P2 together to make the radius arm as shown in Fig. 10.

Solder the radius arm in place. Attach part WM3 and ream through the axle holes 2mm.

Using appropriate washers (part P4) fit the wheels so that there is a minimum of side play. Form the guard irons to shape.

Bend up the spring wire (0.3mm phosphor bronze) to give some downward pressure and solder in place through the holes

in part P5. The pony truck is retained with a 10 BA screw.

SECTION 10: COMPLETING THE CHASSIS MECHANICALLY

Emboss the rivets in parts F16 & F17. Now fold these components to the correct angle using the jig (part F42) as a guide. Pass

part F6 (short side on the left) through the slots in parts F16 and locate all three components on the frames. Check that all is

correctly located, before soldering in place. Similarly solder parts F17 in place. Check the angle of parts F16 & F17 again using

the jig.

Chamfer the curved edges of the splasher tops, parts F18 & F19, and curve to shape over a suitable rod. Now solder them in

place over the top of the frames and against the angle plate. Now trim the excess material from the outer edges of the angled

plate and round off the rear corner as shown in Fig.3. Solder part F15 to the lower edges of part F6 and trim to length. Solder

in place parts F12 and the brake hanger pivots from 0.45mm wire (Fig.3).

In P4, the clearance between the leading crankpin and the slidebar is very limited. Potential problems here can be tackled

by:

Using a recessed crankpin nut as sold by Ultrascale

Ensuring side play on the leading axle is kept to an absolute minimum

Omitting one lamination of the slidebars (LEFT 2 & RIGHT 2).

Fit the crankpins to the wheels making sure the screw heads do not foul, countersinking them if necessary. Attach the balance

weights to the wheels as in Fig. 19. Assemble the wheel sets, bearings and motor/gearbox selecting 1/8" axle washers of

appropriate thickness to control side play.

The cranks on the right hand side should lead the left by 120°. I find the easiest way to achieve this consistently on all three

axles is by looking through the wheels with a magnifier against a strong light and lining up corresponding spokes. The wheels

have 18 spokes which gives 20° between each spoke. 20°x 6 = 120°. So you simply adjust the wheel sets until the right hand

side is 6 spokes ahead of the left. This method is surprisingly accurate and, for me at least, gives by far the best results.

Now connect the motor to your pick-ups and test run.

SECTION 11: CYLINDER ASSEMBLY

Check all the holes in the cylinders (part M1) against the appropriate components and open up the holes if necessary. Reduce

the width of the inside cylinder faces to the etched lines provided as appropriate, so that the cylinders are a good fit it the

slots in the frames. Fold up the cylinders making sure they are square and fold out the 2-to-1 arm bracket.

Solder the valve crosshead guides (parts BR1 or BR3 - front & BR2 - rear) in place aligning them with a piece of 0.8mm wire

passed through the valve rod holes. File away the back of the rear guides as shown in Fig.9.

Construct the slidebars as shown in Fig. 16. Use plenty of solder whilst applying pressure to keep the laminations together.

Clean off the front and rear faces and remove the rear section. The crosshead slot will need cleaning out so that the crosshead

is a good fit. This can be done with a thin file - haven't gone one? - then use a piece of emery paper over a scrap piece of

brass etch. The appearance of the slidebars is much improved by carefully filing the top smooth.

Insert the slidebars in the cylinders and tack soldered in place. After checking all is square and parallel they are permanently

attached. Attach the piston rod glands (part NS2) and check that the crosshead slides properly. Attach the front covers (parts

NS3) and fit the relief valves (parts BR5). Add part M10 as shown in Fig. 9.

Solder together the connecting rod laminations (part M19 & M20) and add the rod boss laminations (part M21) to the big

end back and front. Drill the big end to fit the crankpins and the small end 1.0mm.

Solder the crosshead arm (part M39) to a piece of 1.0mm wire as a pin. Fit the connecting rod to the crosshead, ensuring the

crosshead arm is vertical, carefully solder the pin from the rear and file flush. Fit the connecting rods with a suitable washer

(part M50) between the coupling rods and connecting rods and check the clearance of the slidebar and crankpin nut. You

will possibly have to reduce the thickness of the nut. The connecting rod passes between the two lower slide bars and it will

be necessary to widen the gap between them to give clearance for the connecting rod to pass through.

SECTION 12: VALVE GEAR

All the valve gear joints, with the exception of the eccentric arm/eccentric rod, are made with wire pins soldered on the

inside. This clearly runs the risk of soldering the joint solid. To minimise this:

(i) ensure the pin is a tight fit in the hole.

(ii) use oil or a proprietary solder mask.

(iii) use plenty of flux, a small amount of solder, and be quick!

Modify the motion bracket (part M11) to suit your frame spacing as shown in Fig. 9 and fold it up, with all fold lines on the

inside. Curve the lower ends of the motion bracket over a suitable rod to fit part M13. Solder part M13 in place in the groove

in part M11. Solder parts M12 in the grooves in parts M11 & M13 ensuring that the holes for the radius link pivot align

horizontally and vertically. Solder short pieces of 1.0mm wire to the brackets for the radius link pivots.

Drill out the holes in the radius link laminations (parts M26 & M27) to take the 0.3mm wire pins, which align the laminations

and represent the bolt heads. Solder the inner laminations together with 4 lengths of 0.3mm wire (Fig.11). Check that the

slot in the inner laminations is a sliding fit with the 0.7mm wire.

Place the radius rod (part M33) and radius rod front lamination (part M34) over the radius link, align with a piece of 0.7mm

wire, and solder the lamination to the rod. Solder the 0.7mm wire pin in place and clean off flush. The radius rod should now

move smoothly in the link. Add the fork joint (part M35) to the front of the radius rod. Open out the holes in the radius link

outer lamination (part M26) so that they are a good fit on the pivot wires on the radius link bracket. Solder the outer

laminations in place (N.B. they are not symmetrical –see Fig.11) and cut off the 0.3mm wire to represent the bolt heads.

Gently spring the links in place in the brackets (insert washers part M14 as shown in Fig.9) and check that the links pivot

freely and are vertical. Now remove the links and attach the reversing cranks (parts M28 & M29) using 0.7mm wire so that

they slide in the slots in the radius rods.

Attach the cylinders and motion bracket to the chassis with 10 BA screws. Check all alignments before soldering the motion

bracket to the slide bars.

Form the joggle in the combination levers (part M36) with the fold lines inside reinforcing the bends with solder. Assemble

the rear valve rods (part M40) and union link (parts M37 & M38). Pin together the combination lever, union link and valve

rod. Thread the radius rods through the hole in the motion bracket and pin to the combination levers. Carefully refit the

expansion links and add the reversing cross shaft from 1.0mm wire as shown in Fig.9.

Add the fork joint (part M24) to the eccentric rod (part M23). Reduce the diameter and thickness of the rivet heads so that

they will fit in the recess in the back of part M25. Tap the crankpin hole in the eccentric crank (part M22) 14 BA. Oil the tap

and use it to screw the eccentric arm and a crankpin nut together as shown in Fig.13. Now solder the nut to the arm. Remove

the tap and file off flange of the nut. This gives an arm with a substantial thread that can be tightened on the crankpin. Rivet

the radius rod to the arm and add part M25.

Fit the arms on the crankpin and tighten so that the offset of the end of the arm is 2.5mm (see Fig.27). You may need to file

some more off the nut so that it tightens in the correct position. Now pin the remaining two joints between the union link

and crosshead arm and between the radius link and eccentric rod. Check that the motion works smoothly. By rotating the

cross shaft you should now be able to reverse the motion!

Assemble the 2-to-1 arm (parts M42 & M43) and the front valve rods (part M41) as shown in Fig.14. Pin the left and middle

valve rods, 2-to-1 arm and equal arm (part M45) together. Solder a 1.0mm wire pin in place in the bracket attached to the

cylinders. Make the pin just long enough so that the 2-to-1 arm can be sprung in place over the washer (part M44). Adjust

the valve rods to length so that they do not interfere with the rear valve rods and check for free movement. Fit the right side

valve rod and pin to the 2-to-1 arm. Now link the valve rods together with hoops of 0.45mm wire (see Fig.9) checking that

you have equal backward and forward movement on the conjugated valve gear arms.

This now means that the valve gear is permanently fixed to the cylinders but the complete unit can be removed by unscrewing

the eccentric arms, cylinder screws and the screw attaching the motion bracket.

To ensure a good fit with the valence edge the cylinder wrappers (part M2 or M3) are best fitted after the upper works are

complete.

SECTION 13: FINAL CHASSIS DETAILING

Drill the holes in part F9 1.5mm to fit part WM4. Fold up part F9 (Fig. 6) inserting part WM4 at the same time. Attach parts

F10 and solder the complete assembly to the frames.

Attach the drain cock castings (part BR4) to part F8. Emboss the rivet on the drain cock linkage (part M4) and fold over the

end bracket at the front as shown in Fig.3, before soldering in place together with a length of 0.45mm wire to represent the

operating rod. Add part M5. Make the drainpipes from the 0.4mm copper wire provided, adding the brackets (parts M6 &

M7) as shown in Fig. 3. For the original pony truck the joggle in the pipes to clear the wheels is immediately behind the guard

iron.

The axles are now retained by the springs, formed from a triple lamination of parts F20, F21 & F22. The front springs will

need modifying to clear part F7. Assemble the brake hangers (parts B3 & B4) first embossing the rivet on each lamination.

Attach the hangers to the pivot wires. Emboss the bolts in parts B1 & B2 and solder the cross shaft overlays to the top of part

B1. Fix this assembly to the brake hangers. Complete the brake gear by fitting the front and rear cross shafts and pull rods as

shown in Fig.15.

Complete the chassis detailing by fitting sand pipes (0.45mm wire) as shown in Fig. 27.

SECTION 14: FOOTPLATE

Emboss the rivets on the valences and drag beam (part U1). Fold up the assembly –note there are two fold lines below the

drag beam and the fold should be made on the lower one. Curve the valence behind the drag beam as shown in Fig. 20.

Emboss the rivets on part U7 and add part U9. Fold up part U7 and solder in place behind the bufferbeam and between the

valences so that it is flush with their upper edges. Decide on the correct position of the lubricators (parts BR14 & BR15) and

drill out the appropriate locating holes in the footplate.

Carefully form the bends in the footplate by bending over a rod of suitable size. Now solder the footplate in place with the

valences in the half-etched recess along each side and part U7 in the recess under the front edge. Add part U2 to the rear

drag beam and a 10 BA nut over the middle hole at the rear and over the hole at the front. This now gives a sturdy platform

upon which to construct the upper works. The excess metal is not broken away until the boiler is fixed to the footplate.

Curve the outer edges of part U8 and locate in place over the lamp irons (See Fig.24). Locate the frame extensions (part U6)

and then solder up all the joints at the front end. Add the inner angle using parts U12, U13, U14, U15, U16 & U17 as shown

in Fig.23.

Fit the smokebox saddle casting (part WM10) to the footplate aligning it with the etched guide lines. Solder parts U18 & U19

or parts U23 to the footplate next to the saddle. For the original cylinder arrangement fix parts U20 & U21 together with

parts WM11 & WM12 in place. The outside steam pipes shown in Fig.24 are best left off until the boiler is fitted.

The front end detail can now be completed as shown in Figs. 22 & 24.

SECTION 15: FIREBOX

The boiler/firebox/cab assemblies are doweled together, using 0.8mm wire, for accurate location. An alternative to the use

of wire is 12 or 14 BA screws which are not provided.

Fold up the cab floor support (part C1) and use this as a jig to accurately make the bend in part U28. Pin together, using

0.45mm wire pins, parts U29, U30 & U31 as shown in Fig.26. Fold this assembly along the fold lines and locate together with

parts U28 and U32 to make the firebox cage. Before soldering together check that the 15.1mm dimension (see Fig.26) is

correct and adjust as necessary. Accuracy is very important at this stage if the firebox is to fit.

Clean out the slot for the sanding and reversing rods and round the sloping front edge. The edge of rear former must now

be chamfered as shown in Fig.26. Check that the dimensions are correct.

Solder parts U34 & U35 in place on the firebox wrapper (part U33) before forming the wrapper to shape. Centre the wrapper

on the formers by using the vee at the rear (accuracy here is essential) before tack soldering the wrapper in place. Note that

the lower edges at the rear will overhang the former at this stage so that when they are filed flush with the face of the former

they will fit against the cab front. When completely happy with the location of the former, solder it in place.

Fix parts U36 in place and the upper washout doors (parts U37). Solder handrail knobs in place and add the lower handrail

from 0.45mm wire.

SECTION 16: BOILER & SMOKEBOX

Form the coned boiler (part U40) by rolling and check for fit around the formers (parts U38 & U39). Bend the boiler band

joining brackets on part U41 and fit through the small slots from inside the boiler. If the fit is good and the formers fit then

solder the wrapper ends together with part U41. Solder the formers in place so that they are almost flush with the ends with

the wrapper aligned accurately with the cut out in the rear former. Check the boiler/firebox fit. Represent the bolts in the

joining brackets using 0.3mm wire and solder the handrail knobs in place.

Roll the smokebox/parallel boiler wrapper (part U45) and check the fit on the formers (parts U42 & U43). Solder the wrapper

ends together using part U46 and solder in the formers flush with the back and front with the line on part U43 aligned with

the wrapper join. Attach part U44 to the front of the smokebox aligning the handrail holes. Add the remaining handrail knobs.

Tap the hole in part U39 10 BA, so that the smokebox and boiler can be screwed together. Now check the fit of the

boiler/smokebox to the firebox and saddle. Form the ejector exhaust pipe from 1.0mm wire and attach using parts U50

through the slots in the boiler together with part BR18. Leave it over length as it passes through the cab front the rear. Add

the boiler handrails from 0.45mm wire.

SECTION 17: CAB

Solder the cab floor (part C2) to the cab floor support (part C1). Add the washout plugs from 0.5mm square wire.

Now form the bend between the cab sides and the cab front (part C5). To do this, first scribe, with a sharp point, the fold

lines (make them quite deep) on the inside. The lines run from the slots in the projections at the top and bottom. File off the

marking projections when satisfied and make the folds between the sides and front to match the cab floor. Solder the

spectacle window frames (part C6) in place on the inside. Solder the inner cab window layer (part C10) in place aligning the

small holes for the cab side windscreens (part C14). Solder the sliding window frame (part C11) over part C10 before breaking

off the rear piece along the etched line. The outer window layer (part C12) which retains the sliding window (part C13)

cannot be fixed until painting and glazing are complete.

Solder part C7 inside the rear edge of the cab sides and solder the cab handrails in place. Assemble the cab seats and fix in

place. Form the bend in the cab front and solder the cab sides and cab front to the cab floor. Decide on which fall plate you

require and fit as shown in Fig.25. The tabs on the hinged fall plate (part C3) are folded down and fit in the slots in the cab

floor to give a hinge effect. Form part C8 to shape and solder in place in the slots in the cab front. Solder the safety valves

(part BR11) in place in the holes in part C8.

Anneal the hinges on the cab doors (part C9), by heating in a flame and bend to shape around a 0.45mm piece of wire. The

hinge pins have been made too long so that they can be bent over to stop the doors falling off!

Fold up the back, front and central roof rib of part C15, to give a solid base upon which to build the removable cab roof. Roll

the cab roof, interior detail, and ventilator parts to shape. Solder part C17 in place, on the inside of the roof, as shown in

Fig.22, before soldering the roof in place on the former assembly. Complete by adding the ventilator parts and rain strips

(part C18). Now using a Carborundum disc in a mini-drill cut through the unwanted part of the former and snap off the

redundant parts along the etched lines. The edges of the formers will now need cleaning up.

SECTION 18: FINAL ASSEMBLY AND DETAILING

Now permanently attach the cab/firebox/boiler/smokebox to the footplate by fixing the smokebox to the saddle and bolting

the footplate to the cab. It may be possible to arrange a non-permanent fixing to the saddle to make painting the model

easier but care will be needed in handling the footplate once the redundant material is removed. Remove this unwanted

material in the same way as for the cab roof.

Solder the mechanical lubricators (parts BR16) in position as shown in Fig. 23. Thread parts M46 & M47 through the footplate

holes and locate on the lubricator spindles, but do not solder in place yet. Fold over the crank on part M48, with the fold line

on the outside before soldering in place in the etched recesses under the footplate. Link parts M46, M47 & M48 with a piece

of 0.45mm wire. Add parts M30, M31 & M32 as shown in Fig. 23.

Attach all the remaining parts using the drawings and photographs as a guide to position.

Using the drawing of the cab interior the back plate can be assembled and the cab interior detailed. Use the 0.7mm copper

wire for the pipes.

If you have any problem with the kit or any criticisms or suggestions please contact Brassmasters.
