Jake Posted February 17, 2019 Share Posted February 17, 2019 I've decided to have a go at a 3d printed ex NER Y7. It will be in industrial guise as I gather the two that were preserved both worked in NCB service. I have had some experience at kitbashing, but no successful experience at locomotive building - so I'm hoping this project will be relatively simple and therefore boost my confidence. I'm following the instructions put together by the chap who drew up the 3d print (here https://brackmodels.weebly.com/lner-y7-in-4mm-scale.html) Here's where I've got so far. I would appreciate any information on what livery the locos wore in industrial service, googling has produced few photos so far. Jake 6 Link to post Share on other sites More sharing options...
RMweb Gold Corbs Posted February 18, 2019 RMweb Gold Share Posted February 18, 2019 (edited) Have you seen this one of 1310 with a stubby chimney in NCB service? Edited February 18, 2019 by Corbs 4 1 Link to post Share on other sites More sharing options...
avonside1563 Posted February 18, 2019 Share Posted February 18, 2019 I don't think either of the locos in industrial service ran as originally built. They were both modified in some way, not least of which was the shorter chimney.

Jake Posted February 18, 2019 Author Share Posted February 18, 2019 Thanks. I had run across that first photo, but not the second. Not only is the chimney different, but the open back to the cab seems to have been filled. Link to post Share on other sites More sharing options...
RMweb Premium Dava Posted February 18, 2019 RMweb Premium Share Posted February 18, 2019 Twelve of the class of 18 Y7s were sold into industrial service. Yeadon's register Vol 32 has details including B&W photos of all of them and could be bought cheaply from Book Law quite recently. It has all the Y classes except the Sentinels Y1 & Y3. Lots of detail modifications but some ran without major changes such as cab and chimney heights. e.g. ord & Madison quarry near Middleton in Teesdale bought 898 out of service in 1929 and it ran as withdrawn but with the number on the tankside. I have an 0 Gauge one to build. Good luck with yours! 1 Link to post Share on other sites More sharing options...
Turin 60 Posted February 18, 2019 Share Posted February 18, 2019 You've got a superb finish on the body print, did you need to put a huge amount of work into it? John. 2 Link to post Share on other sites More sharing options...
Jake Posted February 19, 2019 Author Share Posted February 19, 2019 Thanks for the book reference, that's really helpful. The print did require quite a bit of sand, prime, repeat- to get rid of the grainy effect! Link to post Share on other sites More sharing options...
Ian Blenk Posted February 19, 2019 Share Posted February 19, 2019 There was one at Morcambe in the 50's, a picture I think in April '72 Modeller (Going by memory) IB Also useful book 'From Mainline to Industry'. Frank Jones Lightmoor Press Link to post Share on other sites More sharing options...

RMweb Gold Corbs Posted February 19, 2019 RMweb Gold Share Posted February 19, 2019 What an interesting picture. The safety valve cover, I wonder if it is polished or painted? It looks like it was once cared for, but has had a hard life - the green paint job looks rather shoddily applied over peeling layers on the cab, and those large sections of patched side tanks!

Jake Posted March 10, 2019 Author Share Posted March 10, 2019 Some photo's summarising progress. I have got hold of Yeadon's register which has been incredibly helpful. I now plan to base the loco on one of the two which worked for Ord and Maddison Ltd at their Middleton-in-Teesdale quarry. These loco's seem to have kept their LNER number and appear to have an interesting homemade back to the cab. On the model I have successfully had a 'dry run' of fitting the wheels and con rods. Just waiting to be able to paint them before more permanently assembling. As can be seen I have also begun with the detailing on the body- handrails, buffers etc. 5 1 Link to post Share on other sites More sharing options...
Jake Posted March 21, 2019 Author Share Posted March 21, 2019 Does anyone else ever feel like a modelling project is one long exercise in problem solving? A couple of days ago I managed a more permanent assembly of the chassis with loctite holding the wheels etc in place. I put it on the rolling road and it ran which caused much rejoicing! So I decided to run it for 5 mins in each direction just to ensure everything held together. 5mins later the motor worked itself loose and broke the mount (the mount was a part of the 3d print which I had previously broken and had to superglue back on) So, naturally I attempted to fix the motor in place more permanently and today I tested it and the same thing happened. Now, I have worked out that the problem is the bevel gear on the axle isn't quite straight (I had to ream it to the correct size to fit on the axle and obviously didn't do a great job). Hence it was causing the motor to move in order to compensate. So having thought the end was in sight- I've now removed that axle and the offending gear and now have another one on order. It's frustrating. But having had it actually working I feel like the end is in sight! In the meantime I've done most of the body detailing. 2 Link to post Share on other sites More sharing options...

I love the extended bunker modification! Your beast looks great, you have done some serious work there!! Are you going to put the chauldron waggon buffers on the locomotive? Looking forward to seeing the finished article. Chris. Link to post Share on other sites More sharing options...
Barclay Posted March 22, 2019 Share Posted March 22, 2019 I've ruined several of these gears trying to bore one reasonably straight with only hand tools. Mine are far from pefect but a fairly loose mesh seems to help. On my Garratt thread one of our friends has listed a source of bevel gears with a 3mm bore which should help. Looking good though. 1 Link to post Share on other sites More sharing options...

Which just goes to show what I have suspected about 3D printing all along - it's not suitable for locomotive frames. I don't know why the designers of these kits insist on making everything as a brittle plastic 3D print when they should be choosing methods and materials that suit the application. 5 1 Link to post Share on other sites More sharing options...
calvin Streeting Posted March 22, 2019 Share Posted March 22, 2019 (edited) I agree with that. but caveated slightly, pla is brittle abs is a bit more forgiving and can be bent without snaping, but it has a weekness along the layer lines, kind of like wood grain, and it aslo depends on how well the layers fused it can be strong if designed with the layers (grai) in the correct alignment for strength. thats where injection modling is better as it has no layers. i have been known to lamitante (ply wood style) 2 parts to make a strong fixing etc... basicaly understand your tools and materials Edited March 22, 2019 by calvin Streeting Link to post Share on other sites More sharing options...
Jake Posted April 17, 2019 Author Share Posted April 17, 2019 A little progress since my last post. Fixed the gear issue by replacing the gear and reaming it a little more carefully. Now it runs wonderfully, although if anything the gearing of the gearmotor is excessively low- but it will be used on a shunting layout anyway so the low top speed shouldn't be an issue. I've finished the detailing of the chassis as well as adding some weight inside the body. The wires sticking out at the moment are simply because I have yet to fit a decoder so I have been testing it on DC. Besides fitting a decoder, all that remains of the detailing are the additional things I am thinking of adding based on the prototype pictures- chaldron buffers and possibly the modifications made to the back of the cab. 8 Link to post Share on other sites More sharing options...
Jake Posted April 24, 2019 Author Share Posted April 24, 2019 Chaldron buffers made from styrene, and I've made a start on the cab modifications. Decoder installed too. Bought a loco crew at York show, so very nearly ready for painting and finishing! 5 Link to post Share on other sites More sharing options...

south_tyne Posted May 3, 2019 Share Posted May 3, 2019 That looks smashing Jake. I'm really impressed. There are quite a few photos kicking around of the loco at Middleton-in-Teesdale. They are tiny little engines mind aren't they! 1 1 Link to post Share on other sites More sharing options...
Jake Posted May 6, 2019 Author Share Posted May 6, 2019 Thanks for the compliment. I'd be interested to know where else you've seen pictures of the loco because the two in the Yeadons book are the only ones I have come across. I've done a little more work painting the brass work and the buffer beams. Now waiting for my transfers to arrive from hattons tomorrow! 7 Link to post Share on other sites More sharing options...
Jake Posted May 9, 2019 Author Share Posted May 9, 2019 Glazing and crew added. Cabsides prepared for transfers with satin-cote. Just transfers and a touch of weathering to go. 5 Link to post Share on other sites More sharing options...
