bmthtrains - David Posted February 25, 2013 Author Share Posted February 25, 2013 The shell is designed around a 15m tomix chassis, however any motor bogie with a corresponding dummy would fit too. I will post an underside shot for anyone wanting to use a different chassis David Link to comment Share on other sites More sharing options...
RMweb Gold Revolution Ben Posted February 25, 2013 RMweb Gold Share Posted February 25, 2013 (edited) Hello David That looks fabulous. Great work - well done. I am sorry if it's been mentioned before but are both cars powered or is there a "dummy" chassis? Actually, thinking about it, you might want to do a "summary" posting with all the bits shown and with information about where to get them. I bet quite a few will be in the market for one of these pairs seeing your model but won't necessarily have been following the thread all the way through. cheers Ben A.

bmthtrains - David Posted February 25, 2013 Author Share Posted February 25, 2013 Thanks Ben, Both units are powered, simply because the powered chassis were only £16 each, and it would probably cost that or more to print a comparable dummy. Good idea about the summary post, will get collecting the info! David Link to comment Share on other sites More sharing options...
bmthtrains - David Posted February 25, 2013 Author Share Posted February 25, 2013 Summary Information for building the Harsco Rail Grinder Shopping List: 2x 3D Printed bodies from my Shapeways shop (Bmthtrains) 2x Tomytec TM 04 15m chassis (purchased from the ever excellent PlazaJapan ebay shop) Set of decals and OHP transparency window sheets (I can supply these if needed, PM for details) Handrails - I used N gauge fencing bought from BH Enterprises, but any similar would do, cut to shape Horns - bought from BH Enterprises Buffer beam details - spares from Farish/Dapol locos Steps - spares from laser cut scaffolding kit, brass items available from BH Enterprises Construction: 1. Thoroughly clean and prime FUD bodyshells 2. Cut the sides away from the Tomytec chassis as shown below, to line up with the walkthrough on the bodyshell 3. Cut the curved nose of the chassis away to fit into the bodyshell, and add coupling to the inner end only 4. Use the square bogie sides (chassis comes with 4 different types) 5. Paint and apply decals 6. Add buffer details, horns etc I think that covers the basics, and Im sure other people will make a better job of the painting than I have if they want to build one themselves!

RMweb Gold RedgateModels Posted February 26, 2013 RMweb Gold Share Posted February 26, 2013 Thanks guys! The units modelled are the pair 296 and 273 - hopefully both still with us! David hmmm, not wishing to sound like a know-it-all, however our griders are in pairs with numbers like this: DR7926(X), DR7927(X) where X is the set number, generally referred to as UK(X). So UK3 set has numbers DR79263 and DR79273. The cars with the DR7926(X) numbers are designated car1 and the 7's are car 2. This gets complcated when you get to #6 and #7. #6 set is our owned set designated EU1 (currently working in Milan) and #7 is the forthcoming UK7 (built to the same spec as EU1) Hope that helps Link to comment Share on other sites More sharing options...
bmthtrains - David Posted February 26, 2013 Author Share Posted February 26, 2013 Thats just me typing it wrong, it is set 263 and 273. Out of interest, the earlier sets seem to have a much more flaired roof top vent - is that the only difference? David Link to comment Share on other sites More sharing options...
RMweb Gold RedgateModels Posted February 26, 2013 RMweb Gold Share Posted February 26, 2013 The UK grinders had higher intakes when they were first delivered, all have the same lower ones now Link to comment Share on other sites More sharing options...
bmthtrains - David Posted March 3, 2013 Author Share Posted March 3, 2013 A quick update - the second bodyshell is full painted and detailed and is just waiting for its decals. Thankfully the paint took perfectly, I seem to have mastered how to properly clean the FUD ready for painting now, which should avoid any expensive mistakes in the future. Once decals are on this evening, I will get the layout of and give it a test run! David 11 Link to comment Share on other sites More sharing options...
RMweb Gold Revolution Ben Posted March 3, 2013 RMweb Gold Share Posted March 3, 2013 Hi David That looks really good. What method have you settled on for optimum cleaning of the components? cheers Ben A. Link to comment Share on other sites More sharing options...
bmthtrains - David Posted March 3, 2013 Author Share Posted March 3, 2013 Thanks Ben. Cleaning went as follows: soak and scrub with toothbrush in warm soapy water, dry, then scrub with the toothbrush dipped in white spirit, then soaked in water again, and repeated twice until the surface becomes slightly cloudy and no longer slippery to the touch. Was actually quite easy once I knew what I was doing. David Link to comment Share on other sites More sharing options...
Bumpkin Posted March 3, 2013 Share Posted March 3, 2013 How about some 3D printed modern buses in N seen as the nearest are routemasters made by Oxford? Link to comment Share on other sites More sharing options...
bmthtrains - David Posted March 3, 2013 Author Share Posted March 3, 2013 As a diversion while waiting for the decals to set, I've drawn up a modern pedestrian bridge - the type that might do over a motorway or railway tracks. I've designed it as a modular construction - the ramps are individual pieces, and the actual bridge clips together in 100mm sections. To allow for painting, the bridge bases are separate from the 'cages' on top. David 1 Link to comment Share on other sites More sharing options...
bmthtrains - David Posted March 3, 2013 Author Share Posted March 3, 2013 And here we go, the finished model! I'm really pleased with this, not only does it look great, but it's pushed my skills and understanding of the process forward a great deal. The level of detail possible using FUD is quite astonishing, and this really has opened up my mind to countless modelling possibilities. The finish is far higher than I ever thought I would be able to achieve, and only a year ago I never imagined I would be designing and building my own rolling stock. The grinder needs a test run next, then once pay day comes round again, it is the next, even more challenging project, the 09 tamper, which will hopefully look as good, if not better, than this has come out.

Pete Harvey Posted March 3, 2013 Share Posted March 3, 2013 Very Nice David But the steps on the sides should be in line with the doors. I'm sure that there is enough room in there for a sound decoder. Pete Link to comment Share on other sites More sharing options...
bmthtrains - David Posted March 3, 2013 Author Share Posted March 3, 2013 Thanks Pete, the steps had to move to allow clearance for the bogies to turn. Plenty of room for a speaker, but I will leave that enhancement to someone else to work on David Link to comment Share on other sites More sharing options...
shanks522 Posted March 3, 2013 Share Posted March 3, 2013 The Grinder looks excellent David, you should be very proud of what you've made, I'm very tempted to have a go myself although i may try something smaller first. Cheers Graham. Link to comment Share on other sites More sharing options...
backofanenvelope Posted March 4, 2013 Share Posted March 4, 2013 I'm very impressed with your work David and am pleased to see your rapid (sigh ) progression in this world. The grinders look ace, now if I could only find some time to get my fingers dabbling in sketchup! Regards Tom Link to comment Share on other sites More sharing options...
bmthtrains - David Posted March 7, 2013 Author Share Posted March 7, 2013 Thanks guys! I've made the final version of the design available on Shapeways now. Later today I will be giving the units a test run, so pics and videos to follow David Link to comment Share on other sites More sharing options...
RMweb Gold roundhouse Posted March 7, 2013 RMweb Gold Share Posted March 7, 2013 David I will be ordering one in the next few weeks as very impressed. Just got a few other projects on the go before I do. Whats next? Ian Link to comment Share on other sites More sharing options...
bmthtrains - David Posted March 7, 2013 Author Share Posted March 7, 2013 Some shots and video clips of the units being run in on Cross Street this afternoon: Later this month I will be ordering the prints for the 09 tamper, so hopefully over Easter I can make a start on that.

Jim Martin Posted March 7, 2013 Share Posted March 7, 2013 (edited) Congratulations! This is the best thing you've done so far. Even better than your first Pendolino. Since I'm in a gushing mood, I'll also say that both Ring Road and Cross Street are among the most successful layouts in terms of looking like real places in modern Britain.

Etched Pixels Posted March 7, 2013 Share Posted March 7, 2013 Fantastic model. I shall order one once enough pennies have appeared. Now I wonder if I can get the track cleaner in one end of it.... Link to comment Share on other sites More sharing options...
