Early Pattern Lookouts for Dia 38 HR Goods Brake

I have been doing more with the Scrap Tank, but I haven’t managed to take any pictures due to needing flippers outside yesterday.  So instead, lets see something else that was on the test etch that I have recently had returned.

This is the early style lookout for the dia 12 Highland Goods Brake.  As originally built these lookouts formed by a single slot to the centre of the roof and were fully glazed to the front and back.  In use guards complained that they caught their heads on the lip of the roof as they climbed in.  To overcome this, many of the vans were rebuilt to include ramped approaches to the centre of the lookout were incorporated, to become what was arguably the signature feature of the Highland’s rolling stock.

Microrail produced a kit for this van 30+ years ago and this included the latter style of lookout.  I had a pair of these kits and ended up acquiring a third one and I felt I really could not have another one just like the first two!  So I had an inspiration and thought it would be fun to make the early pattern lookout.  The old man’s book came out and a scan of the drawing loaded up into the CAD machine.  From here it was a relatively simple exercise to draw up the difficult bits, the glazed screens, and the more simple roof.

The components went together easily and do give a very different feel to the Microrail kit as intended.   I also made a number of other adjustments, to the footboards and also the panelling, to make the model both different and authentic.  The latter, the beaded panelling, is a right pain in the whatsit and took much longer than any other element of the assembly – so don’t to it unless really want to!  And this is what it looks like next to the kit as originally intended, with the later style lookout.

I will be making these available via the Miscellany Models site shortly, when I have done enough of the other elements I am working on to do a production run.  In the meantime, I do have a pair of very slight seconds (there is a tiny bit of over etching – almost impossible to see, the pictures of my vehicle have the same problem).  These are available for the price of the metal; say £2.50, plus postage (which won’t be much).  Ordering is via here:  http://miscellanymodels.com

And the real thing looks like this:

Scrap Tank Test Build – Part 2; Continuing with the Body

The next stages of the test build were to do the footplate/tank sides/can exterior.

My initial design for the footplate is not particularly radical, but the test build has shown up that until the boiler is put in place (which comes some way into the build process) the front is somewhat delicate, irrespective of whether the footplate valences are fitted or not.  Thus, in addition to the temporary stiffener that can be seen to the front of the footplate in the picture below, stiffeners will be provided to the front half of the footplates.  The idea of these can be seen in the following view which shows the rear of the cab.  By folding these over at 90o during the build, they give strength to the more delicate parts of components.  Some will be incorporated into the finished article, others will simply be discarded when their job is done.

The two tanks, along with the sides to the cab/bunker, are conceived as a single piece (if you go back to my previous posting, you can see this in the flat in the etch).  The two halves are separated by temporary spacers to both assist in locating them but also to give strength to the assembly prior to the fitting of the boiler which is where it will get its strength from.  It was when I tackled this part, I reached the first disaster – the etchers had failed to half etch from behind so I was missing some fold lines.  This was pretty frustrating as it entirely negated the intended efficiency of the  design and even though I now have a corrected etch, I had to solder on by cutting the parts at the intended line of the half etch and soldering them together in the more traditional manner – exactly what my design was intended to avoid.  As a result of this, there are no neat photos of the tanks being folded up and secured in place, we have to jump on a bit to see this.

The cab fronts that were constructed earlier were no slid into place and I was pleased to find that it all fitted very snugly and in exactly the correct location.  I did find that I could put in a further pair of fold up tabs on the running plate that meant that it was essentially impossible to put this in the wrong location, so this is another little refinement that will make its way into the production batch.

The rear of the cab was a similar fold up unit to that to the front, which was pretty easy to build but did have one dimensional error at its base that needed cutting away – well that is the purpose of a test build!  All of this, has been created from one piece in maybe three minutes!

And this is what it looks like with the cab rear in place.  If you look carefully, a couple of 12 BA screws are just visible in the cut out to the rear of the cab – the purpose of these will become apparent in a future posting but it is another one of my little ideas to make this easier to build/better when built.

And this is what the cab bow looks like from above, after the addition of the splasher tops and backs.  One of the issues this illustrates is that this kit, as it stands, will only work for EM or P4 modellers.  There is insufficient room to get the narrower gauge/wider wheel treads into the splashers.

Next up will be the cab roof………….

 

 

Scrap Tank Test Build – Part 1; Getting Started

I took the weekend off the other week and attended the Spring Railway Modeller’s Weekend at Missenden.  It is great to spend two full days just modelling away from the distractions of life and amongst people who are all doing exactly the same.  I find it a form of therapy and it is well worth going if you have been thinking about it (and even if you haven’t!).

I took with me the etches that I have had delivered by PPD for the Scrap Tank; with a view to doing a test build using them.  The origins of this class are some of the earliest locomotives built for the line; the Raigmore class.  In an attempt to increase the life of these new enlarged boilers were fitted to them.  Unfortunately for the Highland Railway the boilers were too heavy for their frames and consequently these cracked.  This left the Highland with a number of new boilers, wheels and many fittings but no locomotives!   Ever the frugal, they recycled these parts into a series of three shunting locomotives which were designed by Peter Drummond and these inevitably quickly picked up the name of Scrap Tanks.

These were rather brutish looking locomotives for the time, characterised by surprisingly large wheels for a shunting locomotive – something compelled on the Highland due to them reusing these from the Raigmore class which were mainline passenger locomotives with 5′ 3″ wheels.  For those of you who don’t know what these looked like, this is what we are aiming at:

And this is what we are starting with:

Whilst this may (well has!) got me into some trouble, I have sought to design the kit to be easier to build than the average etched brass kit and certainly easier than the Falcon Brass kits that are the staple in 4mm for many of the Highland’s locomotives.  I have sought to do this in a number of ways and the first area tackled, the cab front/interior, illustrates one of these; the use of fold up assemblies to assist not only in creating the shapes but also the laminations.  Many of the modern etch designers are using these (especially the 2mm boys/girls) but I have sought to do rather more than most (which has made the preciseness of the design rather more challenging, more of which anon).

The bulk of this assembly starts as a single piece, that is folded up to form the cab floor, splasher sides and the bulk of the cab front.  To assist the lamination process, jigs either side of the cab front have been used.  Wire rods are slipped through the small holes in these to ensure that they are registered on top of each other properly.

The view below shows the laminations now sweated together and illustrates the square cut outs behind the cab front which are to enable glass/Perspex to be slotted in to represent the sceptical glazing.  The view also shows the boiler backhead which is made from three layers of etch (not with a folding jig – yet!).  I am pretty pleased with this as this is only 13 * 15mm in size, so the wheels on the backhead are only 2mm in diameter.

To be continued…………(soon too!).
