The red and white is nice - it'll really stand out on the layout

Not my finest work, but twill do! A 3rd brakevan for myself

Going to take my first stab at 3D printing a loco shell. 
The loco is Cork, Bandon and south coast railway no.7, later Great Southern Railways No. 478.

The history of this locomotive is messy, not unique for the CBSCR with shared numbers, weird rebuilds and so fourth. this was the only steam locomotive built in Cork city. Done at Rocksavage works for the CB&SCR. Some parts were salvaged from the original No.7 (an 0-4-0ST). The boiler likely came a spare Londonderry and Lough swilly railway the CBSCR had purchased at auction. However it’s entirely clear how much of the locomotive was built from spares. 
 

The locomotives main duties appear to have been Cork City Railway working (for which it had a bell attached) and the Kinsale Branchline. The locomotive was withdrawn in 1935. during its life, the loco wore 3 Liveries

Lined CBSCR green

Unlined CBSCR livery of some description

GSR Grey

 
no.7 in a very attractive CBSCR lined Green 

 

No.7 in an unlined livery. Note the bell and CBSC spec boxes towards the front.

Wow! Superb project. What chassis will you use?

The unlined CBSCR livery was also the same olive green, I believe.

Interesting to see that in one of the photos you show there, the engine has a CBSCR crest on the side; but not in the other.

Look closely at the first picture. You can see the very intricate lining on the side tanks, coal bunker and cab. 
 

the other photo is a much simpler livery. One which I presume it wore for most of its life. I’m tempted to give the Lined livery a go though 

 

the matter of chassis is looking like a UK 0-4-4 type or making my own static chassis.

I think a British M7 0.4.4T chassis might well be a good fit.

The 3D print big has certainly bitten! And well done you.

Just comparing the photos with your CAD and:

• Are the side tanks on your drawing a bit too low? Or should the boiler be a bit higher pitched?
• Is the chimney a bit slender and maybe the wrong tapering?
• Sandboxed too big?

 Whatever, hats off for doing such an interesting prototype and definitely a project to follow.

It’s really my fault regarding the sandboxes and chimney. As I was following a GSR spec photo for many of the front details. It seems the smokebox (or maybe the whole boiler) was changed at one point, at another stage later on the chimney was changed. Litterally every single photo has different sandboxes. I was hours messing with the height of the cab. Perhaps it’s the side tanks that should be lower. 
 

I’m not looking for kind of perfect model here. Just something roughly right!

Excellent job!

It’ll look well either way it appeared.

[David Holman]

 Not surprised and continually amazed at how things could change, but as JB says, still looks good!

Sorry to drift the topic a little.

The second photo of No7 (unlined), the cattle truck lurking behind the smokebox, the large, freshly painted "M" seems to be in the wrong place for C&MDR?

Or was it just lettered C (door)  M  or C& (door) MD?

Can't think of another company that would have the "M" there?

 

Edit:- It looks very similar to the C&MDR Cattle and Goods Van I posted in the "Resources" section which you guys still can't see 'cos it's not been approved by the mods yet.

Yes this would be a CMDR Van, which means this taken during the very slim time that the Macroom line connected to Albert quay or its early GSR Times and that’s a midland van (unlikely!) 

[Westcorkrailway]

Works stalled for the time being. But here is how it looks so far. Really 

 

 

 

What I needs now is a bit more work around the safety valves, adding a proper coupling hook.

 

I’ll probably buy buffers and vacuumed pipes rather than printing them. Handrails never print right in 00 gauge, even with this superb printer I have access too so I’ll have to see about getting those in too

in terms of a doner chassis, it looks rough, a bit like the Bandon tank, there is issues with motor height and wheel scale. 478 had very 2 differently designed driving wheels. The leading driver being very distinct indeed!. They were 5 foot while the leading bogey had 2’6 wheels. Thanks to Locomotives of the GSR I know it had 4' 11" + 6' 6" (or 6' 2" + 6'7¾) wheelbase. 

The M7 as suggested has too big Drivers, the SECR H class also has far too big drivers. the Bachman 1p likely wouldn’t fit but it is closer.overall ids say I’ll be looking at simply 3D printing a rolling chassis and no more. 

what I would love though, is too apply something close to this livery on it. Bandon livery is somewhat forgotten to time. Very few alive today could even claim to having seen it. although recently it came to my attention that a coat of arms cut from the side of a coach has survived in the NRM collection. Those who I contacted at the NRM agreed with my hypothesis. I’ve already had one trip to to canned by a missed flight to get a good idea for the green itself. 
 

but to be fair, i suspect it won’t be accurate after years of fade and weathering, but it’s the best I have and besides, nobody is going to prove me wrong! Anyhow this dark green -olive colour was complimented with yellow on black lining

Only certain locos got the coat of arms in the side tanks. The 4-4-2Ts and No.7 are the only examples I found to carry a similar layout. Bandon tanks, J24s, American yolks all wore a simpler livery. 

[Rob R]

How about a Kernow Models(?) LSWR 02?

4ft 10in drivers and much smaller overall than the M7 or  H.

Dunno about chassis availbility though.

Might be worth looking at 060 tanks (panniers?) and doing a bit of butchery, I know the wheels are usually about 4ft 7in but moght just be an option.

[David Holman]

As far as crests are concerned, I wouldn't worry about accuracy. A general shape and colour is all that is needed, so have a look on Fox Transfers website.

 The chassis will need thought though. Gibson or Markits will do a 5' driver, but whether there will be the right number of spokes may be a problem, though the curious balance weights should be easy enough with 10thou plasticard over lay.

 If it is going to be a static model, why not have a go at printing a chassis and bogie, or make them from plastic sheet? A working chassis need not be too difficult - four coupled wheels are a lot easier to do than six. Keep an eye on Tullygrainy's latest build for a 4-4-0, which will point the way.

[Mayner]

Definitely worth considering building the West Cork 4-4-0T with a functioning chassis.

Several years ago Richard Ellis produced a Shapeways GNR(i) 2-4-2T with a 3 D printed chassis and pony trucks, I dont know if Markits have resumed production but Scalelink https://www.scalelink.co.uk/acatalog/Locomotive_Driving_Wheels_.html appear to produce a range of driving wheels which may be suitable and straightforward to use. Coupling rods could be fabricate using Alan Gibson "universal" coupling rod set or even laser cut in nickle silver or even steel, PPD in Scotland offer custom etching and laser cutting services https://ppdltd.com/laser-service.html.

Axle and bearing holes best reamed out and fitted with top hat brushes 1/8" driving axle, 2mm bogie carrying wheels, High Level and Branchlines (Advertises in UK modelling magaxines) supply suitable motors and gearboxes. Parrallel reamers (1/8" and 2mm) for opening up brushes/bearing holes for axles and set of Tapered Broaches for opening up holes in 3d printed chassis, and etched gearbox parts for bearings and holes in coupling rods. In full size practice castings/bearings/motion parts require machining to function.

It might be worth considering printing the loco using a Far Eastern 3D Printing Service such as https://facfox.com/service/sla-dlp-3d-printing-service/ (my preferred supplier) rather than a desktop or home printer. The majority of my wagons were printed in a SLA resin with ABS properties to overcome the problem with brittleness inherent with the majority of SLA resins compitable with desktop printers overcoming problems with printing fine detail parts like brake gear and buffer heads.

Facfox also  has the capability to print parts in aluminium, a NZR 9mm scale modeller (NZR 3'6' gauge on O gauge track) had loco mechanisms (gearboxes, gears, chassis) printed in aluminium for diesel locos.

Lower production/ printing ting costs largely off set the cost of shipping an item (by courier) from China. The shipping of a small order such as the parts for a loco or several wagons about €25.

Customer service excellent (support staff understand my English!) we had some initial problems with parts damaged in transit, only recommendation would be to ask for individual parts to be wrapped individually in bubblewrap.
