Update

To make things a little easier, I’ve made some changes to the site including dedicated pages for the available models.

current models

Anyone who wishes to order should use the contact form and I’ll be in touch.

contact form

After a redesign and several test prints, the Ivatt N1 models are finally ready for order.

The model is available in saturated and superheated boiler versions with add-on parts to cover full or partial condensing equipment. I have also modelled the various pipework arrangements below the running plate so if you have a particular loco in mind, I can probably accommodate it as a special.

The rear of the bunker is modelled without detail but includes holes for most variations of lamp irons, builder’s plate and destination board brackets. This allows the printing supports to be easily filed/sanded off and the detail added afterwards.

This shows how the small parts fit. Note this model is only roughly sanded at the back and the parts temporarily fixed with liquid Pritt stick. The holes are preformed and designed with some clearance, but they’ll still need a little opening out.

Unused holes (for alternative lamp bracket arrangements) should be filled.

Note that since this test print I have shortened the top portion of the front sandbox on the superheated version (bottom image) in common with most as-built locos. The models will have a flat number plate (unless someone really wants a custom one I could add for a nominal cost).

As before, the model is a body only, designed to fit a modified Hornby N2 chassis.

This shows sprue 1 & 2.

Sprue 1 comprises these rear bunker details – lamp iron bases, destination board brackets & builder’s plate, as well as smokebox-mounted lubricators, whistle, & safety valves.

Sprue 2 comprises buffers.

Some of these parts are very small and fiddly, so the models come with spares in case of loss or damage.

Sprue 3 (not shown) comprises condenser equipment – vent pipes, U-bends, and forward pipe sections that plug in below the smokebox.

Price is £44.75 + £5.25 postage and packing for a standard model.

If anyone is interested, please PM me for ordering details.

L&YR Aspinall Class 27 Updated & Reintroduced

Following the demise of Shapeways, I’ve had several enquiries regarding the future availability of the OO-gauge AJModels 3d printed loco bodies. With this in mind, I recently purchased a 3d printer and I’ve been working in the background to modify and improve the models so that I can produce them myself.

After several test prints, I’m happy to announce that the first model for reintroduction is the L&YR Class 27 ‘A’ Class. As before, this is a body only, designed to fit the Bachmann ‘C’ Class chassis (with some minor modifications to the chassis). The tender comes with it’s own 3d printed chassis for fitting 3rd party bearings, axles and suitable wheels.

The model is made from an ABS-like resin which gives a degree of flexibility and handleability. Please note that in these images, the printing supports have only been roughly removed. A little further cleaning up is required.

The body includes chimney, dome, safety valves, reversing rod, steps & smokebox door as a single part.
The tender, loosely assembled.

There are several improvements:

Cab handrails and reversing rod are now part of the model.

Steps are now part of the body and fully modelled.

Redesigned tender chassis, bunker and fitting arrangement.

Remodelled smokebox, boiler, dome and chimney to remove some issues with stepped appearance.

Raised safety valve cover and safety valves now part of the model (previously you had to repurpose the ‘C’ class part).

Choice of buffers with round or square base. Obviously, these are non-sprung. Alternatively, the design allows for fitting Alan Gibson sprung-types.

Choice of BR or LMS smokebox doors.

Refined reverser screw.

Refined brake blocks for the loco.

The model fits the Bachmann ‘C’ Class chassis.
Separate detail parts for buffers, reverser screw, brake blocks & tender toolboxes

As before, the builder will require a Bachmann ‘C’ class chassis, handrail knobs, handrail wire, tender wheels bearings, axles and wheels.

The model is now available for £44.75 + £7.25 shipping (UK Mainland).

Payment by PayPal or Bank Transfer. Leadtime around 2 weeks.

I you are interested in this model please PM me here or on RMWEB for further information.

There is space in the tender for a DCC chip. The smokebox provides an alternative location.
The tender comes in three parts: body, chassis and bunker.

At some point I intend to create the Belpaire firebox version, but next up will be a reintroduction of the Ivatt N1 body.

NER diagram 196 Horsebox – complete

IMG_0931 - Copy

Modeled on an ex-NER diagram 196 horsebox, it’s been a long time in the making but the project is now finally finished. The project has been dogged with problems and as a result it’s been sat in a box over the winter. It has required several reprints and redesigns. Some of this was down to inadequate strength in the rather too intricate design of the underframe which has resulted in a number if compromises and some was down to poor printing. Most of the prints have had warping or drooping to the body part (but never in the same place). Even the final print has not been without problems with some warping of the end part.

I’m fairly happy with the underframe part now – it’s reasonably robust and has survived some manhandling. The roof also is good, being the only part unaltered from the original print. The problems are mainly with the body. As well as the warping the panel details have proved difficult to clean and sand adequately; a little too much paint has been applied to disguise this.

IMG_0932 - Copy

Detailing

Most of the holes are preformed and just required re-drilling in places to clear out the wax from printing. Holes were drilled in the communication cord tell-tale equipment and brass handrail wire inserted through here. The curved handrail itself was formed around a tin of modelling paint and fixed at the top with short proprietary handrail knobs. Steps on the end are by my usual method of transparent acetate sheet cut into strips and slid into the preformed slots. The vertical communication cord run was formed from some fibre optic cable I had – any thin metal wire would work equally well. I formed the door handles from thin brass strip but proprietary examples are available such as from Wizard models (Comet Models C6). Lamp mountings are staples cut to suit. Glazing is acetate sheet.

The roof handles are again brass wire and the vents are 3d printed as separate parts with the model. Sprued 3d parts are also provided for the buffers. These have printed very well but I’ve used 51L/Wizard models cast/turned metal ones for additional robustness (51L NERC028). The brakes are a 3d printed separate part (the early examples were part of the main print and kept breaking). These are glued in place with superglue. The wheels are Alan Gibson 14mm 10-spoked (4015) running in brass top-hat bearings. Additional weight has been added in the body compartment on top of the underframe with some lead sheet – plenty of space here. The model runs nice and smoothly.

IMG_0930 - Copy

As far as I’m aware there are no decals for this diagram so I’ve used Modelmaster’s 8085 decals for the Parkside PC83 LNER horsebox, modified to match a photograph of the prototype. Finally, the model is finished off with a groom – actually a ‘gentleman’ from the Dart Castings range.

I’d have to conclude that this has been a step too far for affordable 3d printing. The detail required has compromised strength and is very difficult to clean/sand satisfactorily. I still have the CADs so if another more suitable process/material comes along I can revisit this project for a better outcome. Therefore, for the time being, I will not be releasing this model on my Shapeways store. However, if you really, really do want this model please contact me here to discuss your requirements.

Hornby J50s for Bowling Street Goods – A Review

Hornby J50

I finally received my first Hornby J50s – a brace of J50/3s – last week and had the chance to have a good look at them last night. In due course they will be renumbered to Bradford Bowling shed locomotives for use on Bowling Street Goods (and beyond). I wouldn’t have minded a J50/4 but there’s no evidence these were used in Bradford or on the Queensbury Lines. There are plenty of reviews regarding the general build, robustness and slow speed running of these models so instead I’ll concentrate on the accuracy and faithfulness to the prototype.

Hornby J50

The overall shape is well captured and manages to convey the slightly brutal and heavy look of these tank locos. In terms of detail Hornby’s ‘design clever’ ethos of a few years ago seems to be well and truly a thing of the past (more on this later). All details are present and well represented including the blower rod, cocks on the smokebox front, reverser rod (hidden in the tank recess), raised tank filler caps, sand boxes with angled steps and undercab injectors (these are very fine, a long way from the old J94 for example). Just the rear lamp irons are moulded onto the body. Parts such as the coal rails and front steps are by necessity slightly chunkier for robustness but still look pretty fine. The guard irons are part of the cast chassis and as such are slightly on the chunky side. A rather nice feature is the wheel boss which is set further out than the wheel rim as on the prototype with the spokes curving outwards towards the centre.

Hornby J50 cabThe inside of the cab is also very well detailed with individually coloured parts. It’s well hidden but one of the best I’ve seen and includes the cupboard at the back above the bunker. As is usual a detail pack includes the brake rigging. Unusually it also includes tension lock couplings as these are not fitted to the model by default. This suits me just fine as I’m not using them but I would imagine there will be some who bemoan this ‘feature’!

Hornby J50 topI do have a few small criticisms and most of these would be applied to the top of the model. In fairness to Hornby there are not many photographs that actually show this detail but the picture of Bradford Bowling shed in the LNER engine sheds book illustrates this area very well (the picture shows mainly J50/1 and J50/2 but there are a couple of J50/3s). The curved plates that form the joint between the boiler and the tanks are a little undersized to my eyes and lack any edge detail or rivets in contrast to this and other photographs. Some locos also seem to have the blower rod recessed into the plate immediately before the cab rather than completely exposed as on the Hornby model (note that I’ve never seen this on a picture of a J50/4). Also there should be a distinct band front to back under the raised safety valve cover to the first boiler band. Finally the exposed fronts of the frames above the front buffers should have holes in for lifting. I imagine this would be an easy modification.

I’ve seen some criticisms of the number of lamp irons (modelled as built to GNR practice) but I personally think this is a case of Hornby being damned if they did or didn’t and trying to cover all eventualities. There’s plenty of photographic evidence to suggest that a number of the class kept the full compliment into the BR-era. If you do need to remove them for your chosen prototype/time period, the front ones are easy to remove, the bunker ones less so.

Hornby J50 R3324

No.635 (R3324) depicts one of the first batch of J50/3s and as such features GNR buffers. These are well done and hopefully Hornby will release them as spares as they’re better than the Alan Gibson ones in my opinion. The loco is depicted as built in 1926 with the safety valves straight on the firebox top and open coal rails. Likewise the livery matches this mid-late 1920s time period with the fine red lining and LNER letters and numbers particularly well applied and looks smart. The full compliment of lamp irons is correct for this particular loco (on the front at least) until at least 1950.

Hornby J50 R3324

Hornby J50 R3326

No. 68971 (R3326) depicts one of the second batch of J50/3s in the post 1956 BR-era towards the end of its life. This batch featured group standard LNER buffers. I’ve not checked to see if these are the same as ones used on any other Hornby models such as the B17. The safety valves correctly sit on the raised cover and the coal rails are plated. The small rear cab windows are also correct for this time period. However, the full set of lamp irons is incorrect for this particular loco at this time.

IMG_0218

Although there is little evidence of the ‘design clever’ ethos in the detail, there certainly is in the construction of the model. Essentially what we have here is a clip together kit of interchangeable parts. Whilst this causes some slight issues – the joint between the body and the cab sides is quite noticeable and would benefit from some filler – it means that Hornby (or indeed the end user, using multiple models) can easily swap, change or add parts do many of the variations associated with this class. One of the announced 2016 models is J50/3 68959 (R3407). This Bradford based loco featured quadrant rear spectacle plates in the BR-era so I will be interested to see if Hornby model this feature with an alternate cab back.

All in all I think Hornby have come up with a cracking model of the J50 capturing its quirky looks and details very well. It’s also a useful loco with a wide geographical range that should make it a good seller and whilst the early LNER liveried model may not be that useful to many modellers the smart livery will certainly attract casual purchasers and collectors.

Hornby J50 Decorated Samples Break Cover

Hornby’s Engine Shed News thread is now showing decorated samples of all three of the forthcoming J50 models. Due for December release they really do look superb models. I had assumed that the LNER version would be of a late-LNER livery but it’s shown here fully lined. I’d also assumed the BR J50/3 version would display the early BR crest, also not the case. So it will be out with the T-Cut and then a new set of transfers. As far as I’m aware the J50/4 type with the built-up bunker did not venture to Bradford or the Queensbury Lines (I’ve certainly never seen a photograph) but I’m tempted to get one anyway for completeness.

Bowling Street Goods – Ballasting

Painting of the track work and the top parts of the coal drops has begun. A task I really wasn’t looking forward to doing however, was ballasting. My previous attempts in the past had resulted in a mess. I’d tried the traditional brush ballast into place then soak with glue route as well as the brush on glue and sprinkle on ballast method. This was no exception – at least to start with.

My first mode of attack was the paint on glue (Copydex) and then sprinkle on method. I found it difficult to get the glue where it was needed and not where it wasn’t needed. Also it was tedious beyond compare. Fortunately, once dry the latex can easily be pulled up along with the ballast. This was duly done and back to square one.

I went back to the traditional method next. The scale depth Exactoscale sleepers helped here, allowing a good space for the grains to sit and not be brushed away too easily as seems to happen with the standard C&L sleepers. I’m going for a fairly compacted ash ballast effect here as it’s a goods yard and I’ve used a random mix of Woodland Scenics fine and medium Cinders. There is a tendency when brushing/tamping for the ballast to sit and build up beneath the rails which is something I wanted to avoid as I wanted to preserve the daylight beneath the bullhead rails. After some trial and error I found it best to work with small quantities, larger grains first, building up gradually over a few inches at a time and then adding the smaller grains last. This avoided the build up. So far so good (and I was actually finding it quite therapeutic). Now for the glue.

BSG_Stack5

I’d heard good report of folks using Klear (or other acrylic based floor polish/varnish equivalent) but I was concerned with the long term durability. With a little experimenting, a mix of Klear and PVA was chosen, about the consistency of milk. After spray misting the ballast with a water/IPA mix the Klear mixture was applied from a syringe working along the edges and then between the sleepers. At this consistency it dribbles out just with gravity and has practically no surface tension. A drop or two between each sleeper is sufficient and the mixture soaks through easily without dragging the ballast with it. I found the drying time to be quite quick and adjacent areas could be tackled safely and cleaning up of stray ballast could be undertaken after around an hour. I would imagine that complete drying would be a few hours so I would recommend leaving overnight to be fully dry. I found for larger areas, a second application of the Klear mix may be prudent. This should be applied only once the first application is fully dry.

BSG_Stack9

Also making an appearance here are the recently weathered ex-PO wagons. These have been finished off with powders to give some variation. Just couplings to do on these now. I think I’m going to go back to the Sprat & Winkle type for this and future projects – 3-link look great but are just too fiddly for my liking.

NER Horsebox – initial report

At the weekend I was able to clean up the print further and check out the fittings. After thorough cleaning an initial coat of primer was applied. This highlighted that one side of the model was crisper than the other. Sanding was rather difficult, as was to be expected due to the panelling. I found it best to work with short thin strips of sandpaper for these parts but inevitably the model is going to be a little rougher than I’d like (also the primer has not atomized very well which hasn’t helped).

A little filing was required to enable the roof, body and chassis to fit properly. The interior detail parts were removed and checked for size. I’m quite pleased with the roof vents. The model is designed so that alternatives can be used but I’ll be using the printed vents rather than the cast metal ones I have which are incorrect. The buffers have printed well also and the only real reason not to use them is robustness. I have some 51L NER buffers sourced from Wizard Models. The images below show both buffers used.

The brake shoe part is a complete failure however. It’s very flimsy and did not fit into the pre-designed slot without a lot of filing. Both sets were broken in the process. I’ve already considered a better solution for this part. Also several parts of the chassis were further victims of manhandling including another spring hanger, both brake lever guards, part of one of the door springs and one of the steps. All of these parts will need to be reinforced if possible. I’ve been asked if I can do a modular version for compensation/P4 by several parties but I’m afraid the answer has to be no as the parts are barely strong enough printed as a whole and some of the parts will be too small to print as sprued items.

So, back to the drawing board for the moment.

NER Diag 196 Horsebox – Printed Prototype

Back from Shapeways yesterday was the prototype horsebox model…

The roof arrived in a separate bag so I’m not sure if they’ve printed it like that or if they removed it or it became detached from the sprue during cleaning. It’s not a big deal and this is what it should look like after printing:

AJModels-04-5461a

AJModels-04-5464a

And with the parts separated and placed loosely together:

AJModels-04-5466a

AJModels-04-5467a

The small add-on parts are tucked away inside the body for safety during transit – the lamp/plug items need some modification:

AJModels-04-5465a

I’m very happy with how the detail has come out, especially the underframe. It is however, very delicate – I’ve already managed to snap off a couple of the spring hangers just by looking at them! I’ll be looking to try and beef these parts up a little. As usual, it’s a fine line between detail accuracy and robustness.

AJModels-04-5471a

Of some concern at the moment is how the parts fit. It’s too tight to fit the chassis on one side and the roof is a little warped at one end. This all may just require cleaning and a little filing so we’ll see how it goes. This was after the first cleaning session and already the fit is better:

NER Diag 196 Horsebox – 3d Model

Inspired by this photo at Wilsden on the GNR Queensbury Lines my next 3d printed model will be an ex-NER Diagram 196 horsebox.

E NER Horse Box Diag 196 behind N1 at Wilsden - Copy

The model is at an advanced CAD stage and will soon be sent for a test print. It will come in three main parts; chassis, body and roof with additional detail parts tucked inside for transit. These will be buffers, roof vents and brake shoes. The model will also allow for alternative metal buffers and roof vents supplied by Wizard Models.

NER Diag 196 1a

I’ve based the model on the Peter Tatlow vol.3 drawing. The roof detail is somewhat sketchy – I have only two images showing this directly and both are very low res. The Peter Tatlow drawing is based on the as-built design and the roof is definitely different in the LNER/BR-era. Also the tumble home is shown as quite curved on the drawing but photographs show it to be much more shallow (compare it with the coach behind in the above photograph).

The model will be available in Frosted Ultra Detail only and the price should be around £55 (inc. VAT) plus delivery at the current exchange rate.
