Brush Type 2 exhausts

A long time ago I started to 'upgrade' a Triang Brush Type 2 ('class 30, 31') and got so far with it - then either got fed up, sidetracked, or otherwise and never finished it.
I found it today in a box and thoughts are turning to doing something with it now. I did lots of research back then but have forgotten most of what I learnt so am starting again.
I always had a feeling that when the Type 2's were re-engined from Mirrlees to English Electric units, that the exhaust ports on the roof got altered, but I could never find any conclusive proof. Over the years I've bought many books and mags with '31's' in, so I dug them all out and went through them all, along with a lot of photos I'd bought. 
Sure enough I found two pictures to prove the exhausts were different. This montage pic shows the difference:
 

Mirrlees above, EE below- the latter narrower and wider, and although not obvious in this shot, mounted on a plate which covered where the Mirrlees one was previously.

 The Triang model, given when it was released- much the same time as when the real thing was introduced, is meant to depict the Mirrlees exhaust layout, though they didnt quite get it right, the hole where the smoke comes out should be offset, plus it's pretty 'flat', it should stand quite proud of the roof.
Quite an easy task to put it right,as I want a model in 'as built' condition.I think some of the central 'walkway' ribbing on the roof isn't quite right in places (need to study more photos) but on the whole the roof is pretty accurate.

COUPLERS

About ten years ago I built quite a few 3mm Society plastic wagon kits, but never got as far as fitting the Triang style tension lock couplings. Now I've got some modelling time, and after a major reorganization and tidy up, I unearthed all those never finished kits.

I started on a box of PP43's (BR 12ton van,plywood sides) then remembered just why I probably didn't finish them ages ago. If you just glue the bar (which the coupling fits onto) behind the headstock on the wagon, the coupling height is wrong. I don't think I ever worked out what needed to be done to correct this back then, but after a bit of measuring with the digital vernier I worked out, on this wagon at least, there needs to be a 0.5mm packing piece between the bottom of the van floor, and the bar the coupling fits onto.

I altered the first one, fitted the couplings and put it behind a Triang 31 on the track. Except it wouldn't fit on the track- because when I made these wagons I intended to do 14.2 finescale, but have since changed my mind and do 12mm now. A quick re-gauge of the wheels and the 31 was happily trundling its way around the 'layout' along with a couple of Conflats. 

Now I've got the space and the time, what was originally going to be the layout along one wall (12.5 feet long, and 27 inches wide) will probably end up going around all the walls of the room. For now a double track  dog-bone scheme will have to do - at least I've got something to run trains on instead of always building stuff and never seeing any action!

MAROON, MAROON, OR MAROON

Will the real Maroon please stand up. This shot taken at Loughborough on the GCR, shows three Mk1 coaches all painted in different shades of BR Maroon. Long time painted ones are a much deeper 'blackberry' shade, whereas more recent paintjobs are a distinctly lighter more 'cherry' colour. Mischievous people might say they are the same shade as they use for their 'crimson' on the red and cream repaints....
But, these different shades of maroon are probably only reflecting how it was 50 years ago;
consult any book with colour shots taken back then and you will find quite an array of maroons,  ranging from very 'pink' shades, through 'browns' to virtually 'purples'. Obviously on some shots the passage of time has affected the negatives/slides, and the various makes of film recorded colours differently; even so you cannot argue when you can see several dinstinctly different shades in a rake in the same shot. I think this goes to show, despite official instructions, that the colour of maroon varied from BR Works to BR Works, and also from outside contractors.
So I suppose it means you can paint your models in any old shade of maroon (Humbrol 19, even?) and get away with it!







It doesn't only happen at Loughborough, you can find different shades  being used at Shackerstone

Here 4939 is behind Griddle Car 1104, which although faded is quite a different shade.

When it comes to model paints, those which were/are available as BR Maroon (Cherry,Southern Pride,Phoenix,Railmatch) were all virtually identical, being the darker 'blackberry' shade;  Bachmann Mk1's dont match up, and curiously the shade Lima used is very close to the shade you see in the vast majority of colour pictures- they obviously went ot a lot of trouble to try and get it what they thought was 'right'.

Another Kitmaster conversion

Also featured in a 1960's Model Railway Constructor was a set of plans for the Southern Region's 4TC trailer sets,which  usually ran  in conjunction with a Class 33 loco. Missing out on green livery, the 4TC's were some of the first things to appear in allover 'semi-matt' early BR Blue livery, which was quite a few shades different (lighter) than the later colour used - a much deeper green/blue shade - although it soon weathered down to look more blue like.
Recalling the class 309 Clacton Express EMU's were uniquely painted in maroon coaching stock livery, I remembered seeing a 'preserved' 4TC set at The Midland Railway Centre at Butterley last year, also in maroon livery. A bit of research revealed it wasn't just preservationists 'wishful thinking'  which resulted in the unit being painted this colour, but that it had been used in some capacity on London Underground (probably specials, tours etc) and it was meant to be in the London Metropolitan Railway maroon scheme.
The 4TC (and earlier short-lived 3TC sets) are more possibilities for Kitmaster coach conversions; A relatively straightforward job with again the most work needed on the driving cars; These cars had the later  smoother cab ends and didnt look quite so 'utilitarian' as those that had been built previously.

A challenge

This would be quite a challenge- a 3mm model of BR Mk1 3083, one of the experimental coaches, with lots of small side windows. Resident on the Severn Valley Railway, it has variously carried red & cream, chocolate & cream, 'fake' varnished LNER teak, and nowadays BR Maroon. Despite a quite recent repaint is doesnt seem to get used very often, along with 1883 the 'Bar' coach.

Seen here at last years diesel gala, being hauled by 'Slug 6'  (37906)  uncharacteristically not blotting out Kidderminster with clouds of black smoke (not that there's anything wrong with that....)


A couple of unlikely pairings hauling trains could also be seen: 14 and 42
and double headed 08's....

The 3mm Society

A timely reminder about the 3mm Society.
Founded in 1965 to cater for all those modelling in 3mm scale, from Triang TT to the scratchbuilder. Well worth the membership fee, indeed some would say worth the money for the excellent Society Magazine alone.






Considered by many to be the ideal scale, it is just unfortunate that there is no current British prototype ready-to-run trade support. Those who lack space for 'OO' gauge, and find 'N' gauge too small often turn to 3mm, especially the active modeller who is not afraid of,and is prepared to 'have a go' at, making kits and scratchbuilding things.

You could have a train running around in no time using secondhand Triang TT stock, just to get you started and keep the interest up until you get up and running properly. In a couple of weeks you could have a rake of Society wagon kits trundling around behind a Jinty or a class 31.

BRUCE SMETHAM CLASS 37

Managed to miss the Postman just before the bank holiday, he left a card saying there was a 'Tube' to collect. I couldn't think what it was so collected it today (the earliest after the holiday I could).  A nice surprise when I got it, my eagerly awaited Bruce Smetham Class 37. I'd seen the Plastikard master for this model at the Kingsbury meeting a few months ago, and ordered one straight away. They were ready at the AGM, but I didn't make it this year, so Bruce kindly posted it on to me.

It's a one piece body cast in cream Polyurethane resin, with extra castings in resin for the fuel tanks, and in white metal for bogie cab steps, bogie sideframes and OLEO buffers.

The body represents the first series of class 37 as built, with split headcode boxes and buffer fairings, the centre headcode version of this model will appear later.







































As can be seen it's quite a faithful representation of the prototype with all the essential detail there. The various contours and shapes, of which there are many difficult ones to capture on a 37 are very well done. The tumblehome at the bottom of the bodyside being particularly hard to get right given it starts to change profile just under the cab door steps, becoming vertical at the nose ends.

Motorization is possible using one of the Co-Co etched brass chassis kits available via the Society shop, though no doubt there are other ways of doing it.

All in all the best 3mm class 37 to date and very good value for money.

Mk.1 COACH ROOF VENTS

Modellers of Mk1 based stock will find at least three different types of roof vent that were used. These were (L-R) the Shell, Scallop, and Ridged Dome varieties illustrated here:















In 3mm scale it would appear that no one makes a 'scallop' type, which is a shame as there are a heck of a lot of them used on Mk1s.

Fortunately the Prototype 4CEP units seem to have used mainly the Ridged Dome type.
An example of one of these can be seen in this pic:







4CEP ROOF DETAIL

Gathering ideas together of my own and other members of the 3mm Society, I did a trial of different combinations of materials to represent the roof conduit/wiring and associated fixings found on the roofs of the cars of a prototype 4CEP unit.








Top is a 16BA flat washer, with a Markits N gauge handrail knob, with 0.47mm  brass wire;
Next is a 2.3mm plastic card disc (15 thou) with Slaters plastikard rod, drilled to take 10 thou Plastruct plastic rod;
Then, a 2.3mm disc (15 thou) with Slaters plastikard rod drilled to take Plastruct  20 thou plastic rod; Finally 2.3mm disc (15 thou) , Slaters Plastikard rod drilled to take brass 0.4mm  wire. The ridged dome roof vent  gives something to compare against to gauge which one looks about right. It's easy sometimes to make something which is very small, too big without realising it.  I think I prefer the bottom one, although the 2.3mm disc will need to be a smaller diameter still ( havent got that far yet...)


despite being N gauge the handrail knob looks way too big!  

Limonene

In the past I've had difficulty successfully gluing largish areas of thin ( 5 or 10 thou) plastikard together. Using something like Plastic Weld, it evaporate so quickly, capilliary action is minimal, with quite a bit of the surfaces to be joined not being reached by the glue. Continuous applications trying to get the glue to penetrate usually end up with a stick gooey mess which wrinkles up. Other brands like MaGer and MekPak aren't quite so thin, still evaporate too quickly and are a bit too powerful to use with larger areas of thin plastikard.
By chance the other day whilst searching for something else, I came across a product I'd not heard of before 'Limonene'. Described as a mild solvent, it looks like it could be useful.
Painting it on it stays wet, so you should be able to paint one or both surfaces of the card and join them together before it starts to disappear. It works very slowly gently melting the surfaces together. With this in mind you might need to clamp things on curved surfaces while it sets. I'm looking forward to trying it out properly. It's got a really strong fruity smell too, the cats werent too impressed!
One thing though, that damned child proof top has got to go. I always get rid of them on solvent bottles, as you really need to keep putting the top back on to stop the glue evaporating away (especially in warm weather). These tops are just a nuisance.

Beware Limonene is not cheap -  £6.00 (UKP) for 100ml, I got mine from Hobby Holidays in Doncaster
(by post).

CUSTOM SANDERS

Workers in small modelling scales often come across situations where something needs to be sanded, but a needle file is too big risking damage to unwanted areas, and trying to use wet and dry paper in very confined or localized areas is very difficult.
Making a custom sander to suit your specific situation is one answer. Using anything handy, a strip of wood, or plastic cut to size and shape, just superglue on a piece of wet and dry paper whichever grade is appropriate to the job and away you go. When the w'n'd is worn out just glue another bit over the top.
I made this one using an old plastic paintbrush handle, with 400 grade paper on the end:



Now I can gently sand away those door bangers mentioned in the last post, so they protrude just the right amount (it's too difficult getting them right just by eye) , without damaging the bodyside.






4CEP CAB ENDS

The cab end of the 4CEP is really just the same as a Mk1 coach, but with windows cut into it and a lot of multiple connections etc added. So following real practice I did the same with the Kitmaster coach end. First I filed off all the moulded on steps and toilet water filler pipes. The bufferbeam needed a bit adding at the base to get the right shape. I decided not to use the original Kitmaster corridor connector as it didnt realy look the part, and made my own from laminations of plastic card, shaped/drilled out where necessary. I think it might look a bit 'chunky' but when you look at the end of these units the corridor connector really stands out as 'spoiling' the looks of the end, unavoidable though that is. 
It might be worthwhile making moulds from these parts to save making all the others individually; perhaps even the whole cab end with the inner plate attached, and the bellows as a seperate item.

The other end of the driving car will have the buffers themselves removed and the  area 'plated over' as buffers are not carried within cars on a unit, just the driving ends.


still a bit of shaping at the base of the outer layer (right) to do


route number boxstill  to make, and the buffer spacings need to be corrected. The last bit to add after assembly will be the flexible part that goes over the top edge. As the bodysides overlap the edges of the cab ends, the  gap between the edge of the window and bodyside will become correct

THE LITTLE DETAILS

I'm hoping to incorporate as much detail as is practical on my 3mm 4CEP model. Bodyside handrails are more than possible - Phil Parker has got them on his Kitmaster Mk1s on FLOCKBURGH , but I wondered if door handles and door bangers could be modelled.Encouraged by tips and advice from other   3mm Society  members I decided to have a go.
I found a packet of  Markits  4mm scale 'T' door handles (ref M4CDHb) , which dont look too out of scale,and for the bangers I drilled 0.5mm holes, fitted plastic rod (Plastruct ref: MR20) standing just proud, then drilled that 0.25mm and fitted more rod (Plastruct ref: MR10) standing proud again- this would be the rubber buffer part.

0.5mm rod fitted, next step drill out 0.25mm and fit more rod


a finished trial door banger. a coat of paint hides many sins. The centre part needs trimming back some more though


Doing this will be good practice for all the roof detail that will need to be added to all four cars- they all have the external lighting conduit/wiring.
