Etched Pixels Posted April 22, 2013 Author Share Posted April 22, 2013 WIA have a delivery from Shapeways.. seems to fit together ok. Need to add some test bogies and take it for a trundle. Link to post Share on other sites More sharing options...
Paul tpxguard Posted April 24, 2013 Share Posted April 24, 2013 Have you tried doing them yourself on a home 3d printer they are fairly smooth and basic shape wise Link to post Share on other sites More sharing options...
Etched Pixels Posted April 24, 2013 Author Share Posted April 24, 2013 The support would be fairly messy that way and I'd then have to polish them myself which is tedious ! I think you are right however - you could print them on a Mendel or similar. Link to post Share on other sites More sharing options...
Paul tpxguard Posted April 24, 2013 Share Posted April 24, 2013 Acetone vapour bath would be best If you split the under frame from the body and put honeycomb infill it would make them flat and strong would you consider selling the file to do this on my printer more fun and it would be more satisfying then paying shapeways Link to post Share on other sites More sharing options...
Etched Pixels Posted April 24, 2013 Author Share Posted April 24, 2013 You'd also have to redesign the articulation if you fill the interiors in at all so its not quite that trivial. Would be fun to play with but not something I have time to do right now and I'd really have to clean up and comment the OpenSCAD file somewhat for it to be useful to anyone else on the planet 8) Alan Link to post Share on other sites More sharing options...

Etched Pixels Posted July 13, 2013 Author Share Posted July 13, 2013 Quick update.. done the end overlay etches, buffers and bits. Still need to make the bogies but now have the wheels for them. Link to post Share on other sites More sharing options...
RMweb Gold roundhouse Posted July 13, 2013 RMweb Gold Share Posted July 13, 2013 Looking good and no doubt a lot cheaper to do a rake of these compared to the other option. Ian Link to post Share on other sites More sharing options...
Etched Pixels Posted July 13, 2013 Author Share Posted July 13, 2013 Ignoring the bogies I think it comes out closer to 50 quid a set if you want two, although you'll still need to make some decals and buy a can of blue paint and some rail grey. It's quite odd but they cost about the same to print two as one. I think it must push it into the cheaper WSF rate or something. Not sure what the bogies will cost yet. Still trying to get some better photos to plan the best way to make them. Link to post Share on other sites More sharing options...
grahame Posted July 13, 2013 Share Posted July 13, 2013 It's coming along nicely. It's difficult to tell because the pics aren't square on but you might want to consider slimming down the thickness of the end frames as the proportion looks a little out; G.

Etched Pixels Posted July 13, 2013 Author Share Posted July 13, 2013 Glad you posted that - I'd been feeling the same. Also the edges are subtly more complicated that the 3D print - if you look at the sides where the pale grey bit is. I shall have a look at adjusting that at some point but I want to get my sets finished first. Link to post Share on other sites More sharing options...
Steadfast Posted July 13, 2013 Share Posted July 13, 2013 Great to see an update Alan, lovely stuff. With regards to the ends, to me it looks more like he etched doors are too small. The angle of the grey looks right, as does the overall shape, so that to me leaves the doors being too small, with too much 'frame' Any other ideas? jo Link to post Share on other sites More sharing options...
bluemattersoda Posted July 14, 2013 Share Posted July 14, 2013 Thanks for posting this Alan! I've been researching articulation for a method to connect my EMU carriages using a gangway rather than couplers. By the way, what do these wagons carry (not many of them in australia)?

Etched Pixels Posted September 16, 2013 Author Share Posted September 16, 2013 Just a quick update. I fixed the ends up but have been busy with other things. The bogies are going for Shapeways test this week (and its a standard mount so various other bogies could be used if it doesn't work out). Given Shapeways is having a 20% off week I've set the WIA set and the buffers to be orderable in case anyone wants one while the price is a bit lower, as they are a fair amount of materials.

RMweb Gold Revolution Mike Posted September 16, 2013 RMweb Gold Share Posted September 16, 2013 Hi Alan They look nice - would they work with WSF polished? (Not that WSF looks too shabby there). Cheers, Mike Link to post Share on other sites More sharing options...

RMweb Gold Revolution Ben Posted September 16, 2013 RMweb Gold Share Posted September 16, 2013 Hi Alan, Nice job! I don't know how accurate you want to be but if the printed bogies don't work out then Bernard Taylor's sprinter bogies, hacked a little, are a pretty good match in terms of basic shape for the WIA ones which, AFAIK, are unique to these wagons (though may be out of sight on some intermodal flats) Cheers Ben A.

As far as I can discover they are unique. The tables I check for european wagons only list the Arbels as using them. Hopefully the fallback wont be needed. Paul: I'll have some resized ones shortly - for my own I plan to just use decals but I will make some for people who want them. I'm trying to keep the parts simply so its cheap - hence the polished WSF shells, and separate FUD buffer pack. Alan Link to post Share on other sites More sharing options...
Paul tpxguard Posted September 16, 2013 Share Posted September 16, 2013 For the buffers I'm gonna use my existing supply of n gauge soc ones how wrong would the atm/society bogies be for height etc Link to post Share on other sites More sharing options...
Etched Pixels Posted September 16, 2013 Author Share Posted September 16, 2013 society bogies on 5.1mm wheels shouldn't be too far out on height. Put it against a class 67 and fettle till they line up 8) Link to post Share on other sites More sharing options...
Etched Pixels Posted October 8, 2013 Author Share Posted October 8, 2013 We has bogies and correct size scale wheels. The bogies work nicely, the pins fit properly. Need to print some small pins for the end bogies. One problem remains - if I put the coupler mounts (eg a NEM mount) on the end bogies it either has to be 1mm too low, or it won't clear the underside of the wagon. Not sure there is space to move the pocket back and up without fouling the body. (the pin visible in the middle of the bogie resting on the floor is just because its not yet fixed into place as I'm not yet ready for a final assembly.

RMweb Gold Revolution Ben Posted October 8, 2013 RMweb Gold Share Posted October 8, 2013 Hi Alan, The bogie looks pretty good. I'd be interested in your assessment of how well it works, and how durable it is, in time. There are a few oddball bogies that are never likely to be feasible for injection moulding and this may be a way forward. On the ATM Arbels we used a body mounted Fleischmann close coupler unit (cat 9574) and fabricated modified couplers with a swan neck arrangement to lift the head up as the shaft does emerge too low. Cheers Ben A. Link to post Share on other sites More sharing options...
RMweb Gold roundhouse Posted October 8, 2013 RMweb Gold Share Posted October 8, 2013 Could the couplers be body mounted as the individual vehicle isn't that long o require truck mounting I would have thought. I could be wrong but it's just an idea to consider if you haven't already Ian Link to post Share on other sites More sharing options...
