Alternative Coupling Analysis

Regular readers of the blog will be familiar with my use of MicroTrains couplers on my O9 locomotives and rolling stock and how this choice was decided upon more than 20 years ago when I wanted to have a single bogie/coupler arrangement for miniature railway outline carriages. I have often wondered how I might cope with an alternative, with the Greenwich couplers I have used on some of my 009 stock in mind. There are even some half-started experiments tucked away somewhere...

Looking around for something to occupy me over the last week, I started another experiment, this time using a familiar wagon in the shape of a Black Dog Mining style open wagon. Previously fitted with MicroTrains couplers I filled in the 5 x 2.5mm openings in the buffer beams with Evergreen styrene and made good the joins. Opting to fit the Greenwich couplers at the standard 009 height a small recess was removed to accommodate the 5.5mm mounting height. A tiny screw from a batch I bought on eBay holds the coupler in place.

The angle of the photo above doesn't really do it justice, but overall the look of the coupler doesn't look too bad. I did additionally try an angled shaft for the coupler to meet the alternative height of 8mm for the face plate but this looked a little more clumsy. I had ruled out directly mounting the coupler higher as it would require a larger cut-out in the buffer beam or a difficult to cut slot.

Underneath there is another change...

As a further experiment 7mm diameter Matheson wheelsets have been fitted, requiring only a little cut-away in the adhesive lead strip underneath to accommodate the flanges. These wheelsets fit nicely and really improve the appearance of the wagon, this is something I will certainly be looking at changing for other wagons using this chassis.

I have to confess that the coupler used here (and the one I bent the shank on) were "borrowed" from an 009 wagon and just fiddling with an alternative loop with a longer dropper reminded me of the one thing I am not 100% sure of with these couplers, assembling them! Yes, there are jigs available now but I find that they are as fiddly as the MicroTrains ones but in a different way. 

So will anything come of this? We shall see, it may just prompt some other wagon tinkering, again regular readers will understand the significance of that statement...

Someone Somewhere (In Summertime)

No apologies for borrowing Simple Mind's song title, I heard it on the radio for the first time in a while on Bank Holiday Monday whilst proving to myself that painting models was preferrable to painting rooms (especially woodwork...). With the end of August now upon us it does perhaps feel that the summer is reaching the end.

Alas there is no modelling progress to report and not a great deal of railway activity to report on at all, our holiday destination of Flamborough being a narrow gauge/miniature railway desert (we "did" Scarborough last year). There is the amusement of the model village at Sewerby and land trains that operate in a railway-like fashion with platforms, passing and turning loops, from there to Bridlington.  

Sitting looking out to sea I could quite imagine something Groudle-Glen style around the headland from the lighthouse to Thornwick Bay...

Not enough to inspire any layout ideas at this stage, I'm still stuck between concepts and spaces, having concluded that Mosslanda shelves are maybe too restrictive, and having taken down a couple of floating shelves recently they do not appeal to me as the basis for anything portable. 

Maybe a trip to the Whistlestop Valley/Kirklees Light Railway gala over the weekend of 6th/7th September might provide a boost, I'm looking forward to the chance to ride behind Bure Valley no.9 'Mark Timothy' having missed out on previous trips to Norfolk.  

Also visiting is the partnership of 'Spirit of Adventure' and 'Mr Hallworth' from the Perrygrove Railway. I think I last saw 'Sprit' at Cleethorpes 30 years ago in 1995 (I had to check that calculation twice...) and I have not yet seen the newer locomotive.

Incidentally, 'Spirit' forms the basis of a new O9 resin print from Gubbin Box Models (Facebook) which allows you to add an Exmoor tank locomotive to your fleet without any of the trouble I had scratch-building 'St Edwin'!

A Black Cat Crossed My Path...

Sadly after 18 years Mr Sooty has now crossed the rainbow bridge. Often found lurking on the bed or windowsill whilst I was working or modelling and he would even give the workshop an inspection from time to time. In December 2008 he was keen to observe the test runs of the Knightwing-based diesel...

But perhaps too keen to inspect the sand dunes!

'Avalon' - Finishing Touches

'Avalon', my subtle reworking of a completed and pre-painted Avalon Line loco is now completed. Having realised that the model was lacking an exhaust I produced one from a length of brass tube, sitting in an appropriately sized hole drilled in the bonnet top.

As an added refinement I added a support on the cab front using a recycled split pin - without realising that one side had no pin from a previous use! It is not noticeable in practice. Both the tube and split pin were blackened using Birchwood Casey gun blue prior to fixing in place. Vallejo gunmetal was used as the basis of the final colour with additional weathering.

I have also added wire loops to the industrial couplers in a 'U' shape, with the top of the side through the coupler also representing the pin of the coupler. These loops were also blackened with gun blue and the bit that was not meant to be there painted with matt black and the pin weathered with gunmetal.

The position of these loops was set in such a way that a MicroTrains coupler can be manually coupled, seen here with my tool wagon. Whilst automatic uncoupling is not possible, for use on a layout such as 'Odsock Corner' that is not going to be an issue!

 

With the completion of 'Avalon' my workbench is looking rather empty and we are getting to that part of the year when modelling slows down considerably and at the moment I don't really have the inclination or motivation to start anything else... So having made a promise to myself just over a year ago to update the blog weekly on a Saturday, and having pretty much stuck to that, I think we are probably now heading for a hiatus...

'Avalon' - a midweek extra

These photos were meant to be pretty much the final ones of 'Avalon' with it's new LRS/Narrow Planet plates in place, but I realised that despite my diligent work, there was something missing...

There is no provision on the model for an exhaust! - so along with adding a wire to the couplers to meet a MicroTrains equipped wagon, I am now adding a suitable pipe from brass tube in front of the cab.

A quick look underneath reveals that I actually primed the chassis frame despite it being invisible in any normal circumstances. It somehow felt more complete that way...

More soon.

Parking up the Mini

Perusing Phil Parker's blog I spotted that he had recently completed a 7mm scale Mini from the Airfix/Heller kit. It is a later model than my Mk1 but interesting to see an alternative approach to modelling one. It did prompt me to carry out one more job on my model, to secure it in place on 'Odsock Corner. But before that I did a little extra painting and scenic work to add a moss effect to the top of the wall, having realised it still looked far too clean! 

So last weekend Saturday morning started with the Mini on it's roof with 1mm brass wire poking out of two of it's tyres... Before going any further, you may notice that I have added some body colour paint to the chassis piece under the front and rear bumpers. This was a result of a review of some more prototype photos and by Phil's model. It looks a different shade here under the light but in place on the layout it is not noticeably different.

I had been wondering for some time how to fix the Mini in place without actually sticking it down. For the Vauxhall Astra on 'Shifting Sands' I used the screw hole that previously held it into the packaging and a suitable bolt through the baseboard. No such luck here... and my original idea to use long 12 BA bolts into the tyres failed when I realised I had nothing long enough. I calculated the thickness of the baseboard and other layers to be getting for 20mm! Using a template I drilled into the tyres and fixed the rod with epoxy resin. It is seen below checking all is well prior to the next stage.

The template was then used to locate and drill the holes in the layout, initially at 1mm but then to 1.5mm to allow a little leeway and for the differences in materials (the wires tended to get stuck having gone on a wander through the foamcore layer over the main ply baseboard top). Here I have held the template using a cocktail stick in the first hole and I am drilling the second hole.

With the holes drilled I positioned the car and then undertook one of those jobs that needs three hands... I held the board on it's side, pushed the car down to the road surface and underneath, slid the inside of a small chocolate block connector over the wire and screwed it on tightly. Did I say three hands? make that four... This actually the system used on 'Shifting Sands' to hold the lamp-posts in place and allows for the Mini to be removed if required at a later date.

Whilst carrying out this work I decided that at some point soon I'll paint up my two remaining Pigeon castings to add to the wall ready to take aim at the car having no doubt added more mess to the wall!

Avalon Loco Progress

Work is progressing well on the reworking of the pre-built Avalon Line loco.  Although I want to keep as much of the original paint finish as possible, I felt that the all-encompassing grey finish needed something to both break it up and add some colour. The obvious and realistic thing to add was an area of red to the buffer beams and/or the coupler blocks. In the end the latter were carefully masked off, only to find that I had no red oxide primer to hand...

After a trip to the local motor factors Hycote primer was applied and then two coats of red acrylic paint.  At first this looked rather stark but with matt varnish and weathering applied they have blended in rather well. The tool box in the cab also benefitted from a touch of colour, a metallic blue and one of the in-cab levers gained a red handle.

Meanwhile I had to source a suitable driver figure. I suppose Although I have some 3D printed seated figures none are in a driving pose but I also have a small stockpile of whitemetal and plastic figures to use...  I seem to recall that this figure was likely bought in Burton Town Hall, but at one of the DEMU shows rather than the 7mm NGA convention where I would have seen Howard and Steve and not bought models like this! 

You may notice that he's had a little surgery (and was a pain to photograph)..

The cap pulled over the eyes to the nose really struck me as not great for any driver, it was only after trying to pose the arms that I realised that maybe the manufacturer meant a road vehicle driver rather than a locomotive driver, and that was his chauffer's cap!  The new head, secured with a short length of 0.5mm wire, was sourced from my oddments of plastic figures and is of Preiser origin. 

What was originally supposed to be a jacket and trousers has become a boiler suit. Painting was my usual primer/dark wash/almost dry brush of colours and to ring the changes the main colour is green, contributing to the splash of colour methodology. His hands are rather big (maybe he's wearing driving gloves) but I don't think is too noticeable once he's in the cab. He looks like he's in control of the loco even if he hasn't got a full grip on the controls.

More soon, as that final picture reveals, things have progressed well...
