LMS FOWLER 4F KIT
The LMS 4F class numbered 772 examples. The first were
right hand drive engines built by the Midland Railway the
LMS continued construction but soon converted to building
left hand drive engines as a group standard. This kit is
intended to represent a typical left hand drive locomotive
constructed in the main batch between 1924 and 1928. As
with any locomotive class built in such large numbers there
was a great deal of detail variations between individual
locomotives. If a model of a particular engine is required it is
expected that the modeller will carry out prototype research
to provide photographs and determine exact details. A few
detail alternatives are included in the kit but the kit is not
intended to comprehensively cover all variations of the class.
However the kit should provide a very satisfactory base on
which to carry out modifications.
If like me the modeller just requires a locomotive that
captures the flavour of a typical 4F then the illustrations of my
models contained in these instructions should provide
sufficient information to achieve this.
I originally designed the etchings for this kit for ACME
models back in the days when money was scarce and I had
to supplement my income by doing occasional kit designs for
other people. When ACME no longer wanted to continue
producing the 4F I purchased the tooling from them and
added it to my range. As I was working to their specification a
few areas of the kit design are slightly different from my
normal practice, for example I would normally separate the
chassis and rods onto a nickel silver sheet. These slight
differences in design will probably only be apparent to
modellers who have built a number of my kits as this kit
builds into a very sound and detailed model.
BODY ASSEMBLY
Parts are numbered in a logical assembly order. The slots
and tabs don't give accurate location, they are only there to
help position parts. Tack solder a part into place then adjust
the next part to match. Solder solid only when happy with the
assembly. I have tried to mark the etchings and provide
location slots so that the positioning of parts is obvious
without the need to constantly refer to complex exploded
drawings. If you are a little uncertain about the positioning of
a component from reading through the instructions don't
worry as this should become obvious as construction
progresses and most parts if offered up to the assembly will
only fit into the correct place.
1. Take the footplate (part 1) determine the top side and
then fold the rear drag beam downwards through 90°. Take
the valances (parts 2) emboss the bolt heads at the front end
and then solder into the half etched grooves on the underside
of the footplate.

Then solder buffer beam

2. Take the cab front (part 4) and
emboss bolt heads. Take the cab
window beading for the centre two
windows (parts 5) and solder into half
etched rebates. On the prototype loco
only the centre windows had raised
beading, the outer two oval windows
had a recessed beading and the half
etch represents this well. Now solder
the cab front to the footplate ensuring
that it is positioned centrally (line up
etched centre line marks) and that it is
upright. If you fold up the back splasher
sides these will also help to provide a
positive location for the cab front.
Take the cab sides (parts 6) and fold
the top reinforcing strip through 180°
and solder on the inside face. Solder
the cab side beading (parts 7) to the
cab side using the etched grooves to
aid location. Take the cab opening
beading (parts 8) roughly form to shape
and solder into place with the etched
groove on the beading locating into the
cab opening. You may also wish to fit
the cab side grab handrails at this point.
Now solder the cab sides to the
footplate and cab front. There is an
etched rebate on the inside front edge
of the cab side to help locate against
the cab front and give a crisp square
corner.

3. Take the cab floor (part 9) and
fold the back edge. Fit into place
between the cab sides locating the tabs
at the front edge into the slots in the cab
front. Fold up the left hand cab box (part
10) and solder into the left hand side of
the cab hard against the cab side and
front. Fold up the right hand cab box
(part 11) and solder into place again
hard against the cab side and front.
Fit the rear cab handrails made from
0.7mm brass wire. The wire is threaded
through the hole in the end of the cab
opening beading and the wire trimmed
to length so that it’s a snug fit
underneath the top of the cab cut out.
Spot solder at top and footplate.

Solder a length of 0.7mm brass wire along the front edge of
the loco to tender fall plate (part 12). Pass split pins over the
wire through the slots in the cab floor and into the holes in
the footplate. Solder the tails of the split pins to the underside
of the footplate. Ensure that the fall plate moves freely at its
hinge and then snip off excess of split pin tails.

Solder the fire box (cladding bands) boiler bands (parts 17)
around the wrapper locating the full metal section of the band
into the etched grooves to aid positioning the bands parallel.
Start 1mm from bottom edge and work around over the fire
box top to the other side. Fold up the two sand box cut out
backing pieces (parts 18) and solder into place behind the
fire box wrapper. The firebox can now be soldered to the
footplate and cab front. Ensure that the assembly is fitted as
square and central as possible. You may find that passing a
length of tube through the holes in the cab front and firebox is
helpful in lining everything up.
Take the smoke box front (part 19) and emboss bolt heads.
Then roughly pre form the smoke box wrapper (part 20) to
match the profile of the front and fix the front face down onto
a flat surface. Solder the wrapper around the front,
positioning the wrapper centre to the half etched line on the
front and working from the centre solder in sections around
each side. Solder the spacers (parts 21) into the slots on
smoke box front making sure that they sit square. Solder the
smoke box rear (part 22) into place inside the wrapper and
locating onto the spacers. When happy with the assembly file
a slight radius around the front and back edges. Pre form the
rivet detail wrapper (part 23) and solder around the assembly
by lining up the chimney holes and working around each
side.
Take a boiler end former (parts 24) and fix to a flat surface
so that the etched ring around the circumference is face
upwards. Spring the end of the pre rolled boiler (part 25)
around this ring and working from the outside and using
plenty of flux, so that the solder is drawn underneath the
boiler end, solder around the circumference. Repeat for the
former at the other end and then dress back with a file.
4. Remove the fire box rear former (part 13) fire box front
former (part 14) and front former thickening piece (part 15)
from the fret. Solder the thickener to the firebox front. Take
the fire box wrapper (part 16) and form radii on the top
corners to match the former profiles. I use a drill shank or
length of tube to help with this. The holes for the mud hole
doors are useful to indicate the centre line of the curved
bend. Fix the front former face down to a flat surface and
lining up the etched centre marks solder the formed wrapper
around the former. Repeat with the back former. Then file a
radius around the front of the firebox.

PAGE 25

Fit the boiler bands (parts 26). The band with the full metal strip fits into the etched groove
around the centre of the boiler and the half etched bands fit at either end. The boiler and
smoke box must now be united and I have found that this is best done by passing a
length of tube through the centre holes of the smoke box and boiler then placing
them onto the footplate and passing the tube through firebox holes. Adjust
the sections until you are happy with their position in relation to each
other and the footplate and then tack solder boiler to smoke box
joint. Remove the assembly and solder the joint solid. If you
wish you can also solder a ring of soft wire around the
circumference of the joint to represent the boiler to
s m o k e box jointing ring. Do not solder the
assembly to the footplate until
after the next stage.

5. Fold the splasher fronts through 90° and fit the
splasher tops. I fitted these before finally fitting the smoke
box and boiler assembly but checked that the smoke box
would fit snugly between the front splashers as I fitted them.
You may wish to fit the boiler before the splashers but access
is then a little restricted.
First using a length of tube roughly pre form the splasher
tops (parts 27) rear (parts 28) centre and (parts 29) front.
Solder into place with the front edge slightly overlapping the
splasher front so that you can then dress the splasher front
with a flat file to achieve a crisp square edge. It may be
necessary to trim the length of the splasher tops slightly.
Fit the firebox to footplate beading strips (parts 30). These
are very useful to tidy up the joint.
Fit the splasher to footplate beading (parts 31) rear (parts
32) centre (parts 33) front. Again it may be necessary to trim
slightly to achieve a snug fit. Using a generous amount of flux
allow the solder to flood into the gaps and joints and then
clean back with knife and fibre glass brush to achieve clean
crisp edges.

For transfers I would recommend the ones produced by the
Historical Model Railway Society, 8 Gilpin Green,
Harpenden, Herts, AL5 5NR. You will require sheet number
2, LMS yellow loco insignia or sheet number 14, BR steam
era loco insignia. They are also stocked by some
specialist model shops such as Home of 0 Gauge.

That should be about everything covered for the loco
construction so now build the tender or if this is already built
paint. Livery is very easy as all 4Fs were black. You should
have numbering details from your prototype research.

6. Take the right hand frame (part 34) and fold the two
lubricator support plates through 90°. Fit the frames into the
slots in the foot plate between the front two splashers.

Take the left hand frame (part 35) and solder into footplate.
I now fit the smoke box and boiler into place on the
footplate. Tack solder it into place first and check by eye from
all directions that you are happy with its position and that the
footplate is not twisted. Solder all joints solid by working in
short sections and checking for footplate twist.
Fit the valve chest cover (part 36) to the smoke box front
and fit two handles made from 0.7mm brass wire.

Originally 4Fs were fitted with long travel valves
and tail rod covers were fitted to the front buffer
beam and I have provided castings for these. From
around the mid 1930s these were removed and a
blanking plate was fitted and for these I have provided etched
plates (parts 104) so check your prototype photos.
Make up the front coupling (see tender instructions for
details) and solder solid into front buffer beam.
All 4Fs were vacuum brake fitted so fit a tall
vacuum pipe. Some locos were fitted with steam
heat pipes for working passenger trains. I have
provided casting for this pipe but I tend not to fit them
to models as I find that they can get in the way of
coupling up on a layout. Also some locos that were
fitted with steam heat sometimes had their pipes
removed for the summer.
Drill out the smoke box to take the handrail supports and fit
handrail made from 0.7mm brass wire. File the tails of the
supports flush with the back of the smoke box door. Fit lamp
bracket (part 47) to the smoke box door and then fit door to
model. I prefer to glue the door into place using Araldite. Fit
buffers into buffer beam.
For the cab interior detail I prefer to paint each item
separately and then glue them into place after the main
model is painted. The spectacle windows could be glazed
with clear plastic sheet but I prefer to cut flat sheets from the
clear blister packs that many items are packaged in
nowadays and use these. This has a textured surface
probably caused by the moulding process, which gives it a
slightly opaque quality that I think represents dirty windows
just right.

solder through the slot in the footplate. Solder a piece of
copper rod through the hole in the top to form a joint pin.
Take the reversing reach rod (part 38) and solder the cover
plate (part 39) on top. Then fit the reach rod through the slot
in the fire box front and slide the other end onto the pin in the
operating arm.

Take the front frames (parts 40) and laminate onto them the
rivet detail overlays (parts 41). Solder them to the footplate
making sure that they are tight up to the smoke box side and
blend in to the splasher curve.
Take the front footplate section (part 42) and solder hard
against the smoke box front between the frames. It may be
necessary to file the part to achieve a good fit.

seemed to be fitted to
most locos in BR days
but check your
prototype photos. I
have provided small

for fitting the early type cover so open
these out using a tapered broach or
reamer to 4.5mm diameter and
remove any burs from around the
holes. Fit the cast clamp into the
round body and then mount into holes
from the inside of the firebox.

A number of different chimneys and domes were fitted to
the 4F class over the years. I have provided two alternatives
for each that cover the majority of the class but again check
photos of your chosen prototype. As a rule of thumb in early
years most of the class were fitted with the Midland type, with
or without capuchin, and tall dome. In later years the taller
LMS Stanier type was fitted with the short dome. My sample
model is fitted with tall chimney and dome just to be different.

8. Fold the back of the rear step treads (parts 43) through 90° and bend
up the two outer corners slightly. Solder the treads solidly into the etched
rebates on the step support plates (parts 44) then fold the top forward
through 90° and solder the assembled step to the underside of the footplate
hard up against the valance. If you have been neat with your
previous soldering you should find that I have allowed sufficient
clearance in the top of the step to clear the cab side tab etc that
projects through the footplate but if the step wont sit down
snugly onto the footplate file away the top of the step until it
does and then reinforce everything with solder.
Make up and fit the front steps in a similar way using (parts 45)
treads and (parts 46) support plates. Fit the grab handles made
from 0.7mm brass wire into the footplate above the steps.
Fold up and fit the footplate lamp brackets (parts 47) noting the
etched marks to help positioning. Also fold up the smoke box
door lamp bracket and place to one side for later use.
I now find that this is a good point to place the body to one side
and construct the chassis. Once a running chassis is achieved
we can determine that there will be no clearance problems with
the body and then the castings and detail work can be applied.
Alternatively you may wish to construct the chassis alongside
the body.

The vacuum ejector had plumbing that you may wish to

addition. Perhaps done at sheds where the loco crew were
fed up with burning their hands.

LMS 4F CHASSIS ASSEMBLY
9. Take the main frames (parts 48) and using a tapered
reamer open out the axle holes so that the turned brass
bearings will be a snug fit. If you are fitting plunger pickups
then also open out the holes for these so that the housing will
be a snug fit.
Take the frame spacers (parts 49) and where appropriate
fold them through 90°. The rear spacer is slightly tight on the
axle gear wheel and so you may wish to fold this one through
95° to give a little extra clearance.
Now pin one side frame down to a flat block of wood with
the top of the frame slightly overhanging the edge of the
block. Solder each spacer firmly into place. Fit second
sideframe checking with an enginers square that the two
sideframes are exactly opposite each other. Tack solder the
second frame at the tabs only and start in the centre and
work to each end. Remove the chassis from the wood block
and check that it is square and not twisted. Once you are
happy solder all joints solid.
Fold the reversing gear weight shaft brackets that project
upwards from the top edge of the frames into inverted U
shapes and reinforce the folds with a spot of solder.
Laminate together the the reversing gear balance weights
(parts 50) and fold over the circular ends to form four metal
thicknesses. Cut a length of 1.5mm brass rod to a length that
will be a spring fit between the frame brackets and thread the
weights onto this and solder centrally 6mm apart. Fit a length
of 0.9mm brass wire through the holes in the ends of the
weights and trim down to slightly less than chassis width and
then solder the 1.5mm brass rod weight shaft solidly to the
chassis brackets.

time spent working on the top surface with knife blade and
fibre brush removing part lines and casting blemishes will be
well rewarded. Any casting porosity marks can be filled with
70° solder and polished back smooth. Check that you are
happy with the way the roof fits and file or scrape the
underside edges if required. Solder the roof into place with
70° solder fitting two lengths of (tinned with 145°) soft wire at
the joints between roof and cab side. Using plenty of flux
allow a generous amount of 70° solder to flow over the wire
and around the joints. Then scrape back with knife blade and
clean up with fibre brush to reveal the wire rainstrips and
blend the cab roof into the sides with no sign of a joint. Drill
out hole in centre of cab roof and fit the roof ventilator.
16. On the prototype loco the boiler handrails were
actually pipes the R/H one feeding the smoke box blower the
L/H one feeding the vacuum ejector.
On the model these are represented with brass tube cut to
length and opened out split pins threaded on. The split pins
are gently squeezed closed at the back so that they form
tightly around the tube and then mounted into the boiler. A
length of 0.7mm brass
wire is fitted into the
tube to continue the R/
H handrail along the
smoke box. The cast
vacuum ejector has
0.7mm brass wire cast
into it and this is fitted
into the L/H tube to
again continue it along
the smoke box.
