The creation of this model started as a challenge to me to create a 3D printed chassis as well as an engine body. I picked the Beyer Peacock 2-4-0T as it worked well with the motor, gears, and wheels I had selected for the job. Over time and several versions of the model it evolved and I got one to work with a Halling motor bogie as a temporary chassis. This was taken to a meeting at the Oldham 009 group in November 2021 where it ran on Paul Titmuss’ 00n3 layout Wood Brook.

It was suggested that it would be a good idea to work up a copy of the Castlederg and Victoria Bridge Tramway Beyer Peacock 2-4-0T but with motion covers and frames on both sides to allow the use of the Halling chassis. With a lot of help from Paul and the 00n3 group, a 3D model was drafted based on the original and confirmed as looking correct. The idea behind this model is to offer to modellers a tempting introduction to the 00n3 gauge.
This also turned into a challenge for a friend who runs a small 3D printing business Thingymaker to see if he could produce a print to compete with Shapeways. This is a challenge that has for several years eluded him. I had a pair of prints produced by Thingymaker and Shapeways. These were both in acrylic resin but using two different processes, so they are not exactly alike, but the level of detail is good and sharp on both prints. Both do take a bit of preparation to make ready for finishing in different ways.

The Shapeways print in Fine Detailed Plastic, as usual, needs the wax support residue removed and a fair bit of surface residue removed from some of the print faces before priming and adding details. But this is as we expect form this material. The Thingymaker print is supported on sprues and they are tightly packed inside the print, so a bit of careful removing is needed to avoid breaking anything off the model. There is also some work to do on the internal surfaces of the print to remove some areas where the resin domes as it finishes printing, a bit like surface tension on a liquid surface. This is a little bit fiddly on some of the smaller parts but not insurmountable

To create the bogie pivot a 12BA cheese head machine screw was used with a couple of washers, one under and one over the bogie frame. The thread was screwed straight into a tight hole drilled in the bodywork where a pilot whole marks the location to drill. The wheel set on the bogie was from a Tralee and Dingle Railway van by Dundas Models. The axles were slightly shortened with a file, turned down in an electric drill to give a clearance fit in the V pockets of the bogie frame, and retained by some 0.45mm wire slotted in holes under the axle in the frame. A small amount of sheet lead was added to the top of the bogie frame to give it a bit of weight, and help it to run better. Lead sheet was also added to the tank sides above the motion cover frames on each side of the body, which seemed to add enough weight to give the model reasonable traction.

A pair of white metal vacuum hoses were carefully reshaped to work on the front and rear of the model. The front one is flat and sitting on top of the buffer beam, the hose retained to the right side viewed from the front. The rear one sits to the left side of the buffer beam viewed from the rear, with the pipe bent towards the coupling hook then under the beam. These can also be done with armature wire of about 1mm diameter.

When painting the model, I gave it a few coats of grey spray primer. Most of the parts are painted separately and added to the model when dry.
The crimson lake I worked with is a mixed colour using Humbrol gloss 20 maroon and a bright matt red Revel M36, the same one I used for the buffer beams. This is toned down on a second coat with the addition of a Revel red-brown matt 37M to the mix which takes most of the shine away but leaves a matt to a satin finish.
I have then dry brushed on some Revel 9M charcoal black to highlight the rivets and shadows on the model. The 9M charcoal black is also used on the foot pate, motion frames, roof, bogie, and smokebox areas. Some parts are highlighted using a mix of the black and silver (gunmetal). Areas like the bogie axles boxes, cab steps, smokebox door handles and hinges, Westinghouse pump, pipework, and handrails all benefit from this.

M.E.W. Island Lighthouse
© 2021 David Hurst All Rights Reserved |
A lighthouse may seem a relatively easy building to make but to get the cone shape right is deceptively tricky since the proportions of the column have to look correct.
Also, forming a glazed housing for the lamp lens with a suitably shaped roof and balcony around it can be a difficult task to pull together. To this end, I had the idea of fashioning a set of parts that could be used to make many different shapes and sizes of the lighthouse.
For my prototype samples, I made a short cone and medium sized cone-shaped tower with which we all associate a lighthouse. I also did a building-style lighthouse with a cylinder shaped tower structure attached, as a comparison to the others. The main materials used in the construction of these buildings was 2mm, foam board, for the base, straight walls and flat shaped formers where required, thin flexible cardboard for anything that needed to be curved, and 50mm wide brown gum paper tape to reinforce the structure (not the reinforced packing type but the smooth art and framing tape). The glazing was a combination of recycled clear acetate and 30mm diameter clear acrylic tubing. I tried both on the lamp lens housing and found the acrylic tubing the best. Doors and windows I obtained from a set of Wills building accessory parts.

The glazing bars can be made in many different ways. For my prototype models, I used 8 vertical bars 1mm x 1mm white plasticard bonded with super glue. It just needs an overlay fitting to the upper part of the outer clear acrylic cylinder which will give the impression of glazing bars. This could be as I have done vertical glazing bars or diamond pattern bars, offset glazing bars were also used in some lighthouses to allow for flat glazing panels.
To guide the installation of these glazing bars, I made a small cylinder of paper to fit inside the acrylic tube and marked the 8 vertical lines equally spaced on this.
I also used a paper ring to form the inner finish of the lower lens housing which is much easier than painting the inside of the tube and gives a nice crisp line at the top.

Doors and windows
I used doors from a Wills set of parts, and also windows and outer frames on the lighthouse building prototype. The openings in towers are formed with just a cutout and some acetate sheet bonded straight to the inner wall surface. The cutouts in the paper for both doors and windows have the edges sealed with PVA before painting.
The printed parts are a roof, balcony, and base ring.
The roof is an eight segment metal clad dome with a ball finial cap. The cap itself has a pilot hole for the addition of a weather vane or lighting conductor to be added. Under the roof, a rim is formed to accept a 30mm diameter clear acrylic tube which forms the lamp housing.
A balcony with railings around the outer edge has a trough formed in the top surface to take the bottom of the 30mm diameter clear acrylic tube. It also has a slot to take the cone formed at the base, with corbels on the outside of the cone for supports to the balcony.
The base ring is designed to allow the cone to sit within a rim in the top surface, and the bottom has a rebate around the outer edge to locate it onto the separate plinth. This plinth is useful to allow the removal of the structure when in place on a layout or diorama making it easier for the permanent fitting of an LED lighthouse lamp fitting.

Painting and finishing sprayed the printed parts and paper parts with a grey primer and then applied the render or paint finishes.
To achieve a render finish on the main tower I have come up with a mix of one part acrylic white paint, one part white powder filler and one part PVA glue, with a spot of washing up liquid to break the surface tension of the PVA. When mixed together a small amount of water is needed to create a smooth paste like texture, this is then stippled in place with a stiff brush. Once dry it can be over-coated with acrylic paints and then weathered.
Weathering was achieved with a mix of acrylic colours yellow ocher, sap green, Payne’s grey, and white. These were applied in thin washes and by dry brushing There is also a rust wash and staining in areas around the railings and balcony, which was done with enamels thinned and dry-brushed.

Lighting unit
The lighthouse simulated rotating lamp effect unit by Mini Lights can be purchased in several different versions and they give a very realistic flash to a static light source. My first sample unit was mounted on a plinth that raised it up into the core of the cone to just under the lens tube. I found it focused the light better by adding a small upstand around the lamp. It is much easier to have the base for the lighthouse separate, so this can be added to the landscape and wired in without risking damage to the lighthouse model itself.
The power for my unit was from a 9V battery. I mounted this in a switched battery box, these are quite freely available on the internet. The units are rated to run on a 7- 13 volts regulated DC power supply or 9 volts battery. To further aid the changing of the battery I added a pair of low voltage plug connectors between the light unit and the battery box.

0-16.5 Engines
© 2020 David Hurst All Rights Reserved |
It was at the Halifax 2019 model railway show that I was tempted by an old Hornby “Smoky Joe” style 0-4-0 engine sitting in one of the second-hand boxes. I had seen some ideas on YouTube about add simple cylinders and coupling rods to these which looked convincing when completed. Little did I think it would lead me into an interest in a new scale of 7mm.
It was some weeks later when I came round to see what I could do with the old Hornby chassis, my first thoughts were the type of engine I could build from the existing bodywork. I found a very good source of inspiration at the Smallbrook Studios web site. They do resin body conversions for the 00 chassis in a 7mm scale, there is also a good catalog of rolling stock and detailed parts.
I found one saddle tank conversion from a Hornby “Thomas The Tank Engine” Bill Loco just what I liked. I look on eBay and was lucky enough to find a body for the Bachmman version of the Bill engine. My plan was to scratch build a new cab and smokebox door, then buy a cast resin dome and water tank lid. Other details I could get from various other sources.
My next thoughts were on the cylinder conversion, I looked up the You Tube video I had seen previously. The parts used on that were spares form a Hornby Class 28XX 2-8-0 Loco Valve gear, I got a set of these from Peters Spares. Only the crossheads and slide bars would be needed for this job so the other bits would be saved for something in the future. To attach the crossheads and the coupling rods I required some very small 14BA machine screws nuts and washers, and eBay came up with a suitable supplier of these.
I would need to build some simple cylinders to fit onto the existing chassis, and remove the existing moulded ones. To do this I laminated together a couple of Placticard blocks and a bridge between them to form a cylinder arrangement. Holes were drilled to give a clearance fit to the crossheads and a tight fit for the slid bars. The chassis was cut to allow the cylinders to sit in the correct place.
The next job was to alter the coupling rods, these needed to be cut in front of the dummy cross heads, and a clearance hole made in the centre of the rod for the 14BA screws. Once done the screws can be passed through from the back of the coupling rods, a washer placed between them and the crosshead, then a couple of nuts used on the outside of the crossheads will lock them in place. It all needs to be a loose fit to work. Once all is fitted together a quick test run will let you know if any adjustments are required for smooth running.
Once the chassis was running, I started thinking, could I 3D print a version of the cylinders and crossheads. So off I went to the computer and came up with a version that used 0.7mm brass wire for the slide rods and cylinder rod. I used White Versatile Plastic to create the prototype print and after a couple of attempts, I got them working. So I added these to the loco I was building.

There came a point when I had to add the Bachmman body to the Hornby chassis, This was not a straight forward fit, but with a little cutting and a bit of Milliput Putty, it went together. By removing some plastic from the bottom of the footplate around the front and rear couplings and infilling a small section to the front of the footplate, where an 8 BA nut could be bonded to the underside. The chassis in turn needed a slot cutting at the back to allow it to fit the rear bodywork. A hole was drilled through the front of the chassis in the centre of the cylinder bridge to allow an 8 BA screw to pass through, this is to hold the chassis and body together. NEM Coupling pockets were fitted in place encased in Milliput putty at both ends of the chassis,
Once I had completed the scratch-built body the natural progression was to see if I could produce a 3D printed version of a body. The only thing to decide what engine to have a go with. In the end, I worked on two types the Skylark style and Peckett style engines which I had already done in 009. These were scaled up and reworked around the new chassis. The idea being, to create a body shell with the cylinders already attached. These could be used as simple conversion to the Hornby chassis by removing the cylinders and couplings from the Hornby chassis, then the chassis would simply push into place under the new body.

If you wanted to go further you removed the cylinders from the printed body also and add the additional printed cylinder block and crossheads to the chassis to create a more detailed version of the engine. They would also have pockets in the buffer beams to accommodate NEM coupling pockets at the correct height. Well, it all seemed like a good idea.

I had two prototype prints done in White Versatile Plastic to try these out, they both fitted the chassis as expected and work well as simple conversions.
I have also done a third body now, this one is a quarry Hunslet style with a cap that can be built in three versions, one open, one with no back, and a fully enclosed version. I just could not make my mind up which I liked best.
I Have now added a Sharp Stewart Tattoo Saddel tank to the ranks of the 0 gauge fleet of small engines. It is printed with some alternative parts such as funnels. This one is designed to run on the 0-6-0 Electrotren chassis with the rear wheels swaped for a 10mm solid disk type to form a pony wheel.

009 Atlas Tram and Coach Conversion
![]() |
© 2021 David Hurst All Rights Reserved |
There is a really nicely modelled Atlas Editions Bern steam tram and coach out on sale at the minute, which with a little careful conversion makes a very detailed steam tram engine and coach set for 009 modellers. The main additions are a Kato 11-110 chassis to motorise the steam tram engine and a set of Peco G-106 bogies. There are also a set of Peco GR-103 NEM pockets and some 1mm Plasticard to form some new interface parts to put it all together. The good thing about this is, if done carefully no intricate painting would be needed to get a really detailed pair of models.
The main difficulty with this conversion is the dismantling of the two models. I found that some parts were glued together more affectivity than others. This can cause some breakages as the plastic used is quite delicate. I found that the worst areas were the railings on both the tram and coach, which broke in several places.

I will start with the coach as that is the simplest and a good starting point to get a feel of the conversion. I removed the wheels, dummy bogies and couplings. The metal used to form the floor of the coach is quite soft and can be cut with a razor saw. The couplings are held on two small metal tabs under the end beams. These need to be cut off in line with the underside of the floor.

To fit the bogies, I created a new subfloor in 1mm plasticard which fitted between the steps and the break gear in the centre of the coach. I left the original threaded lugs used to fix the coach to the display base in place and drilled two holes in the new base to allow for these. The other two lugs to fix the dummy bogies in place I had to remove. This was done by drilling, using progressively larger drills. Once at the bottom face of the floor I formed a countersink to allow clearance for the free moment of the new bogies.
To mount the Peco G-106 bogies all that is needed is a hole of the correct size, and they will just clip in place. These were formed by drilling a clearance hole larger than the bogies require in the subfloor. A packer is then made to sit below this which has a smaller hole suited to the bogie's clips. This needs to be fairly small and inbound of the wheels which need to swing freely. I glued this in place under the hole in the subfloor, lining it up the two holes, which formed a small rebate above the hole in the packer.
The bogies were adapted to suit the steps, by using a set of the Peco GR-103 NEM coupling pockets and cutting these and refitting them to form a long bar type mount instead of the moulded L shaped arrangement. I then glued this to the opposite end of the bogie to the existing NEM pocket. By doing this it had a long enough reach to work with the steps. It was then just a case of fitting my preferred coupling in place.

With this arrangement the coach should be able to negotiate track curves around 200 to 230mm (8 to 9”) and it is a really nicely detailed coach.
The steam tram takes a little more work to dismantle it. The boiler, funnel and pipework are all glued in place then fitted to the base which has to be removed at the bottom, and the side railings are very awkward to get off without breakage. In the end, I removed the roof and windows above the waistline. This allowed me much better access to the bits, but I still had to carefully break the funnel off the boiler. I carefully saved all the bits for re-assembly later, then using the existing base as a template I marked a piece of 1mm plasticard with its shape. I then marked some centre lines on the new base and added a template of the Kato 11-110 cut out.

Once this is cut out and fits in place OK, some stops to position it is needed on the front and back of the cab. It sits 1mm below the original base and there are a couple of ridges on the ends of the bodywork which gives you a good guide to position the stops. A new floor needs adding above the chassis to make it easier to fit the boiler and pipework back in place. This needs to be a fraction smaller than the original base and is supported on a couple of strips fitted to each side, which are about 5mm wide so the whole floor will be raised up by 6mm. The boiler will need to be reduced by this 6mm also. This is just about level with the existing body sides so does not look much different from the original arrangement.

The
one item I could nor repair was the side railings, they were just too
brittle small and fiddly to work with.
A new pair of
railings were made from brass wire soldered together. To make these
easier
to assemble I formed notches in the 1.5mm poles to allow the 0.7mm
handrails to sit in, which
were all held
in place by Blue tack on a cutting mat, then soldered in place.

Removing the roof first makes the fitting of the internal pieces much easier. I assembled it dry then painted the floor and fitted everything back in place before putting it in the body. The railings I had reformed in brass wire and painted silver before adding to the body. This meant that there were four poles to locate in the holes on the underside of the roof and the funnel to glue back in place with the cab ends.
The couplings are a bit tricky to fit, I decided to add NEM coupling pockets. These need a hole making in the correct place, so I sat the body on the chassis and lined up the coach bogie with the skirts to mark the hole position, drilled a hole and filed it out to suit. The pockets can then be pushed in from the back and glued in place.

The body is a little lightweight with the original base removed, so a couple of strips of lead were added to the new floor and also a bit in the boiler for good measure, which seemed to make a difference.

It makes a really nicely detailed set, and the steam tram goes well with other bits of rolling stock.
