Etched Pixels Posted October 8, 2013 Author Share Posted October 8, 2013 Thats the other option I was considering, but having NEM mounts makes a lot of things easier. I can certainly just tap and screw a rapido coupler with a loop at the wagon end into the end itself. Makes it much more complicated to build though. Right now it's not entirely idiot proof but its fairly easy to assemble. Link to post Share on other sites More sharing options...
Etched Pixels Posted October 8, 2013 Author Share Posted October 8, 2013 I've had various WSF bogies running for a while with the pinpoints printed into them and the detail either etched overlays or in this case just printed but without fine detail. The big problem is axle length. I can get away with it for a few bogie types (got an LSWR Dreadnaught bogie on the go for example that'll work), and it only works for the WIA because I'm using much shorter US axles to get the tiny wheels needed. Even then with the wall thickness required (including between the pinpoint centre and surface edges) it's pretty tight. No sign of wear on the WSF bogies I've been running so far, and as its basically nylon I'm not sure I'd expect much wear anyway. Link to post Share on other sites More sharing options...
RMweb Gold Revolution Ben Posted October 8, 2013 RMweb Gold Share Posted October 8, 2013 Hi Alan, Yes, it's a shame Fleischmann don't do a version of their close coupling mount with a NEM socket. I'm not really sure why they don't! I am interested in the WSF bogie concept and as you say, if it's basically nylon then it should be relatively hardwearing - certainly enough for N. I do wonder about the long term stability of some of these materials both in terms of holding their shape and flexibility. It's all so new I guess all we can do is wait and see! cheers Ben A.

Right now it's not entirely idiot proof but its fairly easy to assemble. If there is space under the wagon for a Dapol converter NEM box then that will allow either a Rapido or a Easi Shunt coupler to be installed. I find that even rigid fixed Easi Shunt couplers have more give on tight curves than Rapido couplers. Ian Link to post Share on other sites More sharing options...
Etched Pixels Posted October 8, 2013 Author Share Posted October 8, 2013 roundhouse no - there is space for a coupling arm flat against the underside but not for the box. It's the extra thickness of the NEM box that is the killer. Alan Link to post Share on other sites More sharing options...
Paul tpxguard Posted October 11, 2013 Share Posted October 11, 2013 Will the bogies you've done work wiv ATM axles And will they be on shapeways 4 sale soon Link to post Share on other sites More sharing options...
Etched Pixels Posted October 13, 2013 Author Share Posted October 13, 2013 Tweaking the bogies a bit yet (need to fix the couplers) and then they will. They won't work with ATM wheels, the ATM wheels are a) too big a diameter and b) on axles that are too long. They use Fox Valley wheelsets. Link to post Share on other sites More sharing options...
RMweb Gold Revolution Mike Posted October 14, 2013 RMweb Gold Share Posted October 14, 2013 Hi Alan For the end of set couplers would the Bachman EZ mate couplers (Hattons have some now) work? They are knuckle couplers with a pivot loop and a couple of plastic "spring" wings to center the coupler. I've only seen them used in 4mm so far, but they might fit the bill as they can be pretty shallow to fit - a screw for the pivot through the loop and a couple of strips of plastic to limit the springs either side of the pivot point. Eg: http://www.ehattons.com/38153/Bachmann_USA_78501_Magnetically_Operated_E_Z_Mate_Mark_II_Couplers_Long_12Pr_Card_/StockDetail.aspx Cheers, Mike Link to post Share on other sites More sharing options...
Etched Pixels Posted October 14, 2013 Author Share Posted October 14, 2013 BHE do some loop couplers that if I go in the screw/loop fashion would I think do the trick quite nicely, or even the old Farish loop ones sold as spares by BR Lines. You could certain screw a coupler into the floor there without any real problem I can see. Link to post Share on other sites More sharing options...
Etched Pixels Posted November 30, 2013 Author Share Posted November 30, 2013 So a quick update. Having tried a few things I settled on cheating a bit. I re-printed the bogies with the NEM pockets angled upwards at about 10°. That seems to work nicely and if it offends the sensibilities you can bend the NEM coupling arms 10° at the join with the head quite easily. Unfortunately I screwed up the test resized etch end overlays so need to redo those a shade smaller next test etch I do. As British Rail used to like to say "We're getting there".

RMweb Gold Revolution Mike Posted December 5, 2013 RMweb Gold Share Posted December 5, 2013 Hi Alan A couple of quick questions - I ordered a the WIA set at the weekend and promptly forgot to add the bogies, but on looking at the bogie pack the text talks about enough bogies for one set (6) whereas the body pack was for 2 sets. To confuse things a bit more both the images on the bogie pack show enough bogies for 2 sets, so I need to order one or two sets? Secondly, any idea where to get some of the Fox Valley Models wheels without incurring insane postage charges? Thanks Mike Link to post Share on other sites More sharing options...
Etched Pixels Posted December 5, 2013 Author Share Posted December 5, 2013 The images should always be accurate - the Shapeways rendering is what you get. I'll correct the description right now Annoyingly I've not found a UK supplier of the FV wheels. (The sets are in pairs btw because the main Arbel body shells work out about the same price for two as one - Shapeways have a different pricing for higher volume/density and it nicely hits that) Alan Link to post Share on other sites More sharing options...
RMweb Gold Revolution Mike Posted December 5, 2013 RMweb Gold Share Posted December 5, 2013 Thanks Alan. If anyone wants some of the relevant wheelsets then please let me know as I have just bought rather a lot and will have lots of spares (it was cheaper to buy a bulk pack of 100 than to buy exactly what I needed). Cheers, Mike Link to post Share on other sites More sharing options...
RMweb Gold Revolution Mike Posted December 17, 2013 RMweb Gold Share Posted December 17, 2013 WIA body shells, bogies and (lots of) tiny wheels have all arrived within a day or two of each other so I just need to work out what paint colours to use to get on with building a couple of sets. The articulation looks like a great piece of design. Thanks very much for doing these Alan! Cheers, Mike Link to post Share on other sites More sharing options...
RMweb Gold roundhouse Posted December 17, 2013 RMweb Gold Share Posted December 17, 2013 Mike I will be interested in wheels for a couple of sets if you still have spares. Look forward to seeing your progress on these Arbels. Ian Link to post Share on other sites More sharing options...
RMweb Gold Revolution Mike Posted December 17, 2013 RMweb Gold Share Posted December 17, 2013 Hi Ian No problem on the spare wheels - I have many ;-) We can sort something out next time I see you out and about. Cheers, Mike Link to post Share on other sites More sharing options...

RMweb Gold roundhouse Posted January 4, 2014 RMweb Gold Share Posted January 4, 2014 Yesterday I ordered the Arbel prints from Shapeways. Alan - hows the etched overlays coming on? Regards Ian Link to post Share on other sites More sharing options...
Etched Pixels Posted January 5, 2014 Author Share Posted January 5, 2014 Been done for a while but waiting me having time to finish off the sheet and get it all off to be etched. Christmas/New year was taken up by relatives so I got a lot less done (and enjoyed myself a lot more ;-) ) than planned. I'll let people know once I've got some here and tested, but they *will* get done - I need some to start with ! Link to post Share on other sites More sharing options...
RMweb Gold roundhouse Posted January 15, 2014 RMweb Gold Share Posted January 15, 2014 The prints arrived today - UPS know which house to leave them at during the day these days. A Good job these neighbours happily take them in for us. Not had much time to do anything with them this evening but did put a couple of pieces together and they all appear to fit well. Thanks to Mike I now have the wheels, so one bogie has these in place. It is possible that a set will be running at the Pontefract show in just over a weeks time. Mike - have you settled on any particular paint colours? Regards Ian Link to post Share on other sites More sharing options...
RMweb Gold Revolution Mike Posted January 15, 2014 RMweb Gold Share Posted January 15, 2014 Hi Ian Glad you got the wheels OK - sorry I missed you, I was in the pub next door I've picked up a bottle of Vallejo's Model Color Pastel Blue (901 or 63 in their numbering) to try - I've only got primer on mine so far. I'm not convinced it is right, but we'll see. I just went into Ian Allan at Waterloo and tried to pick a reasonable shade for a reasonably dirty/slightly faded set. I'll look to use something metallic for the ends. Cheers, Mike Link to post Share on other sites More sharing options...
RMweb Gold roundhouse Posted January 16, 2014 RMweb Gold Share Posted January 16, 2014 Thanks Mike I heard that they were using Wetherspoons for lunches - a nice idea. Thats where I am p;ammomh to go to pick up some of those paints if I get chance today. Regards Ian Link to post Share on other sites More sharing options...
RMweb Gold roundhouse Posted January 17, 2014 RMweb Gold Share Posted January 17, 2014 Last night I managed to get a coat of primer on the bodies. This morning a set of five had the sides slightly rubbed down and a second coat. Hopefully today I will get chance to go to Ian Allen and get some suitable colour paints to get the finish coat on them on Sunday. Link to post Share on other sites More sharing options...
