RosiesBoss Posted September 6, 2019 Share Posted September 6, 2019 Introduction I’m an “old-school” modeller, having been involved in the hobby since the 1950s. I’ve been working in plastics, balsa, card, brass, etc for many years. Some of my projects may be found at the references listed below. When 3D printing appeared a few years ago, I looked at it – in particular at a machine owned by a chap in my Bible Study group – and decided that it looked to complex a task to learn a new set of designing skills. A couple of months ago, my generous son gave me a surprise 70th birthday present – an Ender-3 3D printer and three 1kg rolls of black PLA filament. It took a few days to put it together and adjust it until I could produce a successful test print, but then I looked around for a couple of simple modelling projects. On Thingiverse, I found a freelance Manning Wardle styled 0-6-0T body (Ref.1), which could be mounted on the surplus Hornby Terrier chassis I had in my spares box. This was generally similar to “Matthew Murray” on the Middleton Railway (Ref.2). Plenty of images abound for this loco, so I printed the file and started to assemble the model. Construction 1st print: After cleaning up: The surface finish was still too rough, so it was rubbed back with abrasive papers and nail buffs and then roughly primed and painted. The plastic internal spigots were replaced by 8BA threaded rods, which located perfectly into the Hornby chassis. Test fitted to the chassis it looked like this: The finish was still too coarse, so further rubbing back was done. The body sat too high on the chassis, so clearances for the leading wheels were cut out. The motor was painted blue. It was obvious that it needed a firebox/backhead, so a very basic one was designed and printed: New handrails, buffers and a smokebox dart were then added: Just before painting, I realised that the safety valve vent pipe above the firebox was missing, so one was made from a piece of brass tube and fitted. Finishing The body was painted blue using Games Workshop “Citadel” Caledor Sky acrylic. Other colours were Humbrol enamels. Suitable transfers for a name and builder’s plate were added, together with Dapol crew and “coal”. She was ready to work: Reflections The model is still pretty basic, but it does work. It has been an interesting introduction to the joys(?) of 3D printing and made a nice change from other techniques and materials. I am grateful for the free availability of the files for the downloaded body.

RMweb Premium JimFin Posted September 6, 2019 RMweb Premium Share Posted September 6, 2019 Lovely job and great to see 3d printing used in conjunction with other materials where they are more appropriate and new skills being learnt. Link to post Share on other sites More sharing options...
RMweb Gold JCL Posted September 6, 2019 RMweb Gold Share Posted September 6, 2019 It's always good to learn something new and keep the cells buzzing. Now that you've finished your model, what do you think of 3D printing? Is it for you? Link to post Share on other sites More sharing options...
RosiesBoss Posted September 6, 2019 Author Share Posted September 6, 2019 G'day, all, Thanks for the comments. It's early days yet, but I think I will continue to use 3D to make bits and pieces I can't make easily by other means. I'm currently making a 4mm scale model of GWR 2195 "Cwm Mawr", mainly from brass and copper, but using a saddle tank/smokebox from a Hornby "Smokey Joe". Its chimney/safety valve/dome fittings will be made from brass on my lathe, but I'm currently designing a set of injectors to be made by 3D. Let's see how this works out. Regards, Rob 5 1 Link to post Share on other sites More sharing options...
Vanguard 5374 Posted October 6, 2019 Share Posted October 6, 2019 As the designer of this model, you have done a great job. I wasn't happy with how it looked, but this is a great improvement. Really happy to see it used to make a decent model. 1 1 Link to post Share on other sites More sharing options...
