Dia 51 Test Build – Part 2: Nearly There

I no longer affix roofs firmly to the body of my coaches as makes both the building and the painting much easier.  The downside of this is that there is the challenge of keeping the roof on tight without there being any visible joint between the two as this looks terrible.  The solution I now use is to clamp this to the floor with 10BA bolts by way of brackets as can be seen in the photograph below.

As built, these coaches had full length step boards but they lost most of these through their life.  They were electric fitted from the outset.  The chassis below is close to finished except I have run out of vacuum cylinders so these will need to be added, along with the vacuum pipes.

The bogies are also a key part of the proposed kit and are something that I have been working on with Justin Newitt of Rumney Models – the idea being to combine the sprung bogie design that he has prepared with cosmetic etches for the sides and then the castings from Lochgorm Models or perhaps our own in due course.  The bogie is quite sophisticated with both primary and secondary springing – the latter is on the bolster and is as below.

The primary springing is on the axleboxes and has bearing carriers, much like the Bill Bedford sprung W-irons.  There are still some wrinkles to iron out so it is not there yet but they do make up into some pretty neat bogies; don’t you think?

The only area of the first test build that truly did not work was the corridor connections and it is going to be a case of back to the drawing board for these but other than the final few bits to be completed, the build is finished and I think the vehicle is handsome.

So, off to the paint shops soon, but there is a bit of a holiday to squeeze in first!

Dia 51 Full Brake – Test Build Part 1

Following the last delivery from the etchers, it was time to get on and do the first test builds.  First up was the dia 51 Full Brake.  This vehicle was one of the later coaches from the Highland Railway and was of similar design to the cove roof corridor coaches that have been available from Lochgorm Models for some time.  They were also amongst some of the last highland coaches to service as tool vans etc.  This is what one looked like late on in its career after its corridor connections had been removed.

As with my efforts for the scrap tank, I am seeking to try and be a bit smarter with some of the kit design to draw together ideas of assembly of my own and also those of others.  So starting with the ends, these will be made with a double skin to both provide the footsteps and, less commonly, some tabs to allow the sides to be secured to them.

I have always found that too many etched coaches have flimsey sides that become distorted as they are made (or when ham-fisted me does anyway).  Therefore,  I have designed this such that the head and base of the side have significantly sized stiffening pieces, as can be seen below.  These are designed to interlock with the tabs at the ends such that most of the locating of the parts is largely defined by the kits components.

Once the basics of the shell are together, this is what it looks like.

The roof proved to be one of the most challenging parts of the build.  I had originally designed this with an inner to form the shape of the roof and then a thinly etched outer layer to go over this to provide the rainstrips and other detail.  It proved too difficult to get the two to laminate well or even be rolled to a similar curve.

Instead, therefore, I ditched the outer layer and relied only on the inner.  This had been half etched on the underside to assist its rolling to the curved profile.  I found that it was still difficult to roll the roof due to the tightness of the curves at the extremity of the roof but by simply using bending bars it was quite easy to put the curves in with a limited amount of faceting.  Faceting is where short straight sections with bends to the next short section that gives the impression of a curve.  Once this was then filed on the outside to smooth out the facets, a smooth curve became pretty good.  Thereafter, it was necessary to form the rainstrips with wire and file them back to square sections and as you can see, the effect is pretty convincing.

The underframe and bogies are to follow, in part 2.

Transfer Update

Back in November 2013, I hinted that I was trying to crack transfers for the Highland’s locos in LMS days; something that is not realistically available via other sources and there does not seem to be much prospect of anyone else doing them.

Anyway, hopefully, I have cracked all I need to with regard to these and the final artwork is complete.  This is what it looks like – hopefully it has covered all the locos you might fancy!

Highland Names

Also on the sheet are one or two other things; but I am less certain that these will work so I’ll keep these as a secret until I find out.

The intention is that these will be available in 4mm & 7mm scales; pricing to be confirmed but I am afraid they will be fairly expensive as the production run is not big and you 7mm chaps in particular eat the page with the size of the prints!

Once they come in, I decide whether they are viable.
