Dirty Models……..

Now, I wonder if that heading will gather a few extra viewings………..?

As I have mentioned before on this blog, every few months I catch up with a group of mates to have a joint modelling session.  The general gist of these is a combination of banter, a bit of modelling, more banter, a visit to the pub, even banter, a bit more modelling and all nicely rounded off with some more banter.

Last week  saw us on the south coast to do some weathering – or rather some of us.  One of our number was preparing for their imminent marriage whereas Oly (one half of OTCM) felt his budding TV stardoom was a sufficient excuse to hang up his airbrush.   We do fear that Oly may not return to the fold; preferring instead to do his modelling with Brad, Leonardo and Denzil once he makes his silver screen debut in the autumn – don’t forget your roots Oly……….

We were all concentrating on different things; Peter constructed the better part of a bridge for his Aultbea layout and Chris was weathering some rather neat little shunters. For my part, I concentrated on weathering some of the stock that I have been building lately (and sometimes not so lately!):

IMG_3809

First up is a pair of horseboxes.  On the right is my HR version based on a Microrail kit – still in need of some glazing.  On the left is the Caledonian’s equivalent based on a kit from by Spratt & Winkle.  Both are in their pre-group livery as can be seen.  As such stock was used in passenger trains, I have sought to give them an aged but largely cleaned feel – with the dirt largely present around ironwork and difficult to clean spots.

IMG_3812

Having mucked up the weathering of some brake vans at the previous weathering session, I was also keen to get these corrected.  This is where I have got with them.

As can be seen, I do not follow the school of thought that the pre-group or 1920’s era stock was constantly pristine.  If you bother to look at contemporary photographs, little is clean and some of it is downright grubby.  Railways in the steam era were very dirty places; it is inevitable where so much coal, ash and smoke prevail.  Furthermore, I can not see even the most houseproud of railway companies regularly (or probably ever) cleaning their goods stock and most of these show stock that is care worn and soiled.  This is the feel I am seeking to capture; not the utterly neglected and on its last legs look of the final days of steam but of railway materials that earn a living the hard way.

The pair of brake vans above are to HR diagram 39 from 1922 and are from a Lochgorm Models kit.  There is some doubt whether they were delivered in 1922, as there are no known pictures of any of them in HR livery.  However, I applying the “its my trainset rule” a number of modellers have painted them in Highland colours; including Paul Bannerman whose example is below.

The other highland brake van I weathered was the diagram 38 brake van.  This originates from a Microrail kit and may well still be available from David Geen occasionally at shows as he does own the rights to the artwork.  I have modified this with the early pattern roof look outs.  These allowed the guard to look over the train around the twisting curves that characterised parts of the Highland’s system.  However, there were complaints about whacked heads as the guards came up and down the steps to look onto the lookouts and as a result they were modified with approach cutouts on the roof – take a look at the Lochgorm’s page above to see an example.

Next up on the weathering front were some wagons and NPCS.  The first pictures being the weathering to a couple of the items I have described in the pages here – the Oxford Rail NB jubilee wagon and the Mousa Models LNWR van.

And then some rather more ancient models of mine, a Highland Railway meat van from a Sutherland Castings kit and a GC van from another Mousa Models kit.

Finally, a group of wagons for Benfieldside.  The hoppers have been seen before and the brake van we will hear more of another day.

More Weathering Results

The class 24 skinhead was not the only output from the weathering day last weekend – indeed, it was a very busy day!

20160611_180408

First up were some of my 1920’s rilling stock – both Highland, a timber truck from a Model Wagon Co whitemetal kit and a horsebox from a Lochgorm etched kit. Both are now close to finished – a load is requird for the former and some glass for the latter (and probably a light colour inside the groom’s compartment.

Neat vehicles though and I am pleased with them – less so than the brakevans that I managed to dislodge the lettering upon and may well need to be stripped – as you would imagine, no photos of these and nor any photo’s from today’s efforts with paintstripper!

IMG_1073

But the main additional output was some more coaches for Portchullin.  I managed three and Peter Bond looked close to finishing his third as I left, so we had a proper little production line going!

20160611_170128

The technique was essentially the same as I described for the class 24, although as you can see the model was broken down rather more (in part to populate the interior of the carriages – I do hate seeing trainloads of empty coaches on model railways!).  However, for the maroon coach, rather than using thinners to take back off the paint, T-Cut was used.  This is an abrasive so does not work in quite the same manner but acheives broadly the same effect except that it also polishes the paint.  I did not think this was right for the blue/grey coaches (they were finished in satin in reality) but the maroon coaches were in a gloss finish and the T-cut gives a slight sheen without actually getting to gloss.  I did eventually think it was a bit too shiny, so did waft over with the finest of sprays of the “gunk” again just to take it back a touch.

The Bachmann Mk 1s are very good models that have stood the test of time well.  They are a doddle to convert to P4; taking maybe 60-80 minutes a go.  There are a couple of things to look out for – firstly is that the side frames are a touch to tight for true guage wheels and need to be filed back.  The plastic is quite flexible and does create burrs fairly easily, so once the filing has been done some work with a sharp scalpel is required to clean this up.

Mk 1 Bogie 2

Mk 1 Bogie

The next caution is that the bogie mounts are not always parallel with the rail head, meaning that the bogie can lean forward or backward.  This is caused by the chassis being screwd a little over-hard onto the body, causing it to flex slightly.  You are just as likely to have done this as the manufacturers and I get around it by making it rock slightly with some thin (20 thou) strip like this.

Mk 1 Bogie 3

Arguably one of their weaknesses is the corridor connection which is a tad toy-train (well it is a toy train!).  A dodge that I have started to do is fit a few of my vehicles with some black foam in the door jambs.  Make this so that it sticks out 3-4mm and engages in the equivilent of the adjacent vehicle to block out the light.   A simple dodge that makes a big difference.  It does mean that the vehicles that are fitted thus have to be in the centre of the train (as the foam looks crude where it is exposed) but this can be done with care – for example a buffet would nearly always be in the centre of a train, so this is the vehicle of the two I fitted with this.

New Shoes for Some Old Friends

Over the last few weeks, I have been revisiting a number of model coaches that I have built in the past, typically quite some time in the past as most of these have been around since either my teens or twentys!

Over the years techniques have changed and I undoubtedly would not build most of them in the manner that I originally built them if I was confronted with doing them again.  Having said this, on the whole my handiwork – especially in respect of the painting and lining was really quite good.  I seem to have lost my lining mojo in particular, so I am not sure I could line as well as this now.  This is something that I really must get to grips with this, as I still have a lot to do!

IMG_0862 compress

a pair of full brakes, the one to the left is a West Coast Joint Stock (from a London Road Models kit) and that to the right is straight LNWR (from a Microrail kit)

But the biggest area of difficulty with the coaches is that the bogies were generally formed around beam compensation units.  These are OK for a couple of coaches behind a branch train but they impart far too much friction for a full main-line train as I aspire too.  This is impossible to overcome whilst retaining the compensation units, the bar is the cause of the problem and it has to go!

To overcome this, Bill Bedford sprung boiges are being retro-fitting to all of my existing stock.  These rely on separate hornblocks that secure a pin-point bearing in them – so rolling resistance is significantly reduced.  The hornblocks are held in place by way of guitar wire and the effect is that they glide around the trackwork.  They thus give the impression of weight and inertia that is much better than compensation (it is possible to get compensation that does not use the rocking beams that are the cause of the fritchion I am complaining about).

A Midland & North British luggage composite (from a PC Models kit) and a LMS (ex Midland) dining car (from a 5522 Models kit).

The Bill Bedford units are only an inner bogie and they still need to have some form of detailing on the outside.  Some of these have entirely cosmetic outers, either of plastic or white metal but the two Midland coaches and the Highland TPO have something slightly different.  On these, I utilised the original etched bogie sides and laminated them onto the Bill Bedford inners.  This is very successful as it improves the Bill Bedfords notably by making them a lot stiffer and you get the crispness of the etching process.

IMG_0869 compress

This is one of my fathers, so I can’t claim credit for anything but the bogies.  A Highland Railway TP (fully scratchbuilt).  Obviously, no painting has as yet been done, so it does rather look like a ganster with gold teeth!

IMG_0873 compress

It is rather challenging to see how the Bed Bedford sprining unit sites inside the outer skins (from a Lochgorm kit) – so I will write up the process in a future blog – but this is what it looks like from the outside.

If, by the way you fancy some Fox Pressed Steel bogies that are neatly sprung and look the part – and almost all pre-group modellers ought to – keep watching the space. Subject to a test build or two, there will shortly be one available on the market.

IMG_0822 compress

To test them, I took them and a few other coaches to ExpoEM to use their test track.  Here we see a Barney with eight on – albeit a rather od mix for the train and there is a fair amount of painting and lining still to be done.

And to prove that they really do work and also to allow you to see how they glide, a quick youtube video:  https://www.youtube.com/watch?v=6D7a_cWwGhg&feature=youtu.be

 

 

 

Scrap Tank Test Build – Part 7; Boiler Assembly and Finishing the Cab

Next up is the finishing of the detailing of the cab.  Common with many tank engines there were grilles over the rear windows.  For these, I toyed with the idea of doing these as a single etch, a bit like the Mainly Trains one (and possibly others) but elected instead that the slight roundness of the bars needed to be captured, so this meant that brass rods were going to be required.  If I had either etched small holes or soldered these on top of the cab etch, I felt that getting consistency of spacing was unlikely and that this would detract from the finished effect.  Thus, it was time for a little jig.

This jig is simply a sheet of brass with holes for the wire at the appropriate spacings along with half etched lines arranged such that when the jig is folded over, the wire is trapped between them.  This is what it looks like with the wire in and the jig folded over (along with a dab of solder to hold it all still):

Window grille 1compress

You will note that in the picture above, I have trimmed the wire rods to a gentle curve to reflect the curve of the spectacle plate and in the picture below, this has been soldered on the ring around the window.  The jig is then snipped off and the rods can be cut away.  I found that by using a scalpel, it was possible to cut a nick in the rods and then the wire could be carefully lifts so that it snapped at the point of the nick.  It was necessary to ensure that the rods were soldered well to the sides as if this joint failed it was then pretty difficult to get them soldered back down neatly; I will include a space jig in the production etch of the kit to give the user a second chance!

Window grille 2compress

There is also a beading around the cab side openings, a common feature on pre-grouping locomotives.  This was relatively simple to fit, although I did make it a tad too fat deliberately to assist in the process – it can then be filled back to a thinner dimension and in the process any slight irregularities taken away in the filing.  In this example the stanchions are probably a bit far away from the cab sheets, so there will be a slight adjustment on the final version.

numberplate cab compress

Also worthy of note is the cabside number plate, which I am dead chuffed with.  This is a cruel enlargement as the whole plate is only 6mm across and to clearly be able to read the text which is only 0.7mm high is pretty good I reckon!

After finishing the cab detailing, it was time to add the boiler onto the tanks/running plate and she is beginning to look like the real thing, although perhaps looking a little naked due to the missing dome and chimney at present!

Combined 5compress

I have fitted a safety valve bonnet and safety valves from  those intended for the Strath/Loch and available from Lochgorm Models.  I also formed the front splashers, which I had tried to make easier by the use of some tabs and formers.  These did assist in the assembly but I then found that they fouled with the wheels, as I had made the splashers true to scale and the tolerances did not allow for the tabs.  I will have another think here and might come up with a jig, as splashers are sometimes a bit painful to fit.

Combined 1compress

And this is what she presently looks like; definitely beginning to look like the real thing (a reminder of which is below).  For those of you that are coming to Scalefour North I will bring her along for you to have a look at.  As we are now about up to date with her construction (you didn’t think I can build that quickly did you?!?!) and because I am away the whole of this weekend at Scalefour North, there will be a hiatus a bit before the next posting.

Scrap Tank Test Build – Part 6; Boiler and Running Plate

Now that the much of the bulk of the above running plate work has been completed, the running plate valences can be fitted.  As these are nearly always long and thin, they are prone to distortion in the kits I have built – so it is time for another jig!!  This one holds the valences at numerous places to stop it flexing and to hold it straight.

_DSC0286compress

With this, it is a doddle to fit the valences in their correct place and solder them without distortion.  I did find that the running plate flexed significantly at the end of the tanks; so the final version is going to include a pair of temporary stiffeners that fold down and stop this.  This would be the moment when they are removed to allow the valancing to take their place.

_DSC0352compress

And onto the boiler.  In a departure from normal practise, I am not including a flat etch to be rolled into a boiler – it is relatively difficult to get even a pre-rolled boiler into a neat tube without a visible seam and if you do not have a rolling machine it is effectively impossible to do so.  In addition, where boilers have been half etched to create boiler bands I find that the half etched elements that remain are overly delicate.  This was something that caught me out a while back when I drilled such and area to take handrail knobs and badly distorted the metal – this kit is still sitting in its box now and I am probably going to have to replace the boiler.

With these problems in mind, I simply used a piece of brass tube from Eileens; easier and much more durable and if I were sratch-building I would not even think of taking a different route.  This did still leave the need for some rolled parts, to make the smokebox and I have sought to use another little trick here to make these easier to fit – some tags and eyes.  The tags are strips of half etching that pass through the eyes and then tugged back.  This can’t impart a curve into the metal but does allow the parts to be pulled tight and makes it easier to solder into place without much of  lip.  Mind you, they were a tad short and will be lengthened slightly in the production run.

Boiler 3 compress

A second additional laminate is then needed to form the outside of the smokebox and down onto the saddle.

_DSC0349compress

I did find another little error when it came to the front of the smokebox.  Whilst the diameter for the front that I had drawn had allowed for the thickness of the two laminates, when you fit these there is also a layer of solder between them and whilst this ought not be that thick, it was just enough to make the fronts too small.  In the production run, I will deliberately make this a tad too big as it is easy enough to file it back but much more difficult to add the missing metal (I didn’t, I just made a fresh one from sheet metal).  The smokebox door is not mine, the door from the Lochgorm Models Loch is the right size judging by the photographs (note the drawing in the old man’s book has it being smaller but this does not match the photos, so I ignored it in this respect – sorry Dad!).

The downside of using tube as a boiler is that boiler bands need to be considered.  I have provided these in the kit (again using the strap and eye technique).  I chose to fit them on this kit although in practise I think any metal boiler band is too thick and would probably have done it with a transfer sheet if this was not a test build (done prior to painting, the thickness of the transfer is enough to show through the paint on what will be a single colour to the boiler).

Boiler 4compress

Only the top of the boiler is visible after the first ring and a bit, so can be cut away to leave lots of room for the motor, weighting and DCC chip.  I may try and fit this with sound, so who can give a view on what it might have sounded like – a jinty is my favoured guess?

Christmas is the season for…………. jolly well finishing stuff off!

Over the break, I have been concentrating on trying to finish things.  Like many people, I find it much easier to start a kit or project than it is to get it fully finished.  Indeed, do we every truly finish our models – certainly not our layouts!

Back in March 2013, I completed a dia 39 goods break.  These were the final Highland Railway break vans and it is not clear that they were actually finished prior to the end of the HR era.  Given that I model in the mid 1920’s, I am quite content to do this in LMS grey which to date I have not seen the model depicted in!  The main body painting has been completed and the van has been lettered but weathering, the interior and final detailing/glazing is still to be completed.  Based on the Lochgorm Models kit with minimal adjustments (a few pipes below the chassis and sprung W irons in lieu of the compensation provided in the kit) this is what it presently looks like:

_DSC0209compress

Also coming through the paint shops are a pair of vans.  The first is a Great Central van build from a Mousa Models etched brass kit and the other is a LMS early standard van from an injection plastic moulded kit from Cambrian Models.  Both are pretty simple models to build; the Mousa Models one was built as designed and no adjustments were found to be necessary.  I only fitted springing to the Cambrian one and got rid of the rather too thick W irons in the process.  Again the bulk of the painting is complete, but some dirtying work is definitely still required.

_DSC0204compress

Apologies for the slightly squiffy photos; I left it a bit late in the day to take them and the light was poor.  I have made a lot of progress painting the NER hoppers, but the photos of these really did not make it and need to be repeated.  Something to post tomorrow I suspect!

More on my casting and etching

We haven’t had an update on the etching and mastering that I have been doing for the signals for a while.

Well, I have had both the rapid-prototype  masters and etching in.  Using the former, I have also had my first set of lost wax casting done – in this case for the lamps and finials.  This is what they look like – which I think is pretty good and a lot better than the white metal ones from MSE.

_DSC0569compress

and the etching looks like this – brackets, arms, ladders and a few other bits and pieces.

_DSC0551compress

So it was time to make a signal – in this case a fairly simple single arm Highland signal.  So using a post from Lochgorm and then my parts for the arms, spectacle plates, windlass, balance levers, ladders, finials and lamp, this is what it has come out like:

_DSC0004compress       _DSC0578compress

and the castings close up looked like this.

_DSC0577compress   _DSC0574compress

So all in all, I am pretty chuffed!

It does mean that I think there is some more signal building to come on these pages……….

Diagram 39 Brake Van

The latest completion off the workbench is a goods brake van.

This is a diagram 39 version; which was the Highland’s last brake van design (and there is some speculation that they were not delivered until after the start of the LMS era but if someone has a photograph in HR days, we would be all eyes!).  These were quite modern by the Highland’s standards and were the first ones for several decades to do away with the lookout on the top of the roof which was likely to be a retrograde step given all the twists and turns of the Highland’s lines.

100_2092compress.

It was built from a Lochgorm Models kit; constructed mostly as intended. However, I elected to insert some sprung suspension using Bill Bedford sprung W irons, rather than the designers intention of compensation. I also found that the sides were a little tall, so these needed to be cut down a tad. Other than this, it is was pretty easy. Having bought some of the NBR Models etched builder’s places, this became the first model of mine to be fitted with one – so a small first!
