andygif Posted August 7, 2013 Share Posted August 7, 2013 I cant believe that neither GF or Dapol have even mooted doing a rail crane. I'd be up for a pair of 75 C&S cranes, wallet willing of course. Might even buy the kirov just for a laugh and paint it yellow, ok its out of my era, but i'm applying rule 1. Beside i've already got most of the other N Gauge cranes already. Tried to get whiteboar fell in another tread interested in trying his R&R 45 toner in N, dont think they were very interested the OO version looks great tho.

bmthtrains - David Posted August 7, 2013 Author Share Posted August 7, 2013 I would be careful with the side tipping MRA as Dapol already do it in 00 so may have it in their plans to produce it in N. Otherwise all of the other models look like a good idea. Especially the Cowen Sheldon 75 ton crane. Would like to buy one of those when it is done! Just waiting for there to be a Kirow crane sized hole in my credit card and I will be buying the wagon and crane set! Alistair Thanks Aistair, The joy of 3D printing though means that the risk of doing a design that might end up in RTR form is quite low - the only costs I incur are my own time and any prototype prints, so if someone then brings out a RTR offering of one of the models, although it kills future sales, Im not left with unsold stock etc. Interestingly, although I've invested around £2000 this year in developing the models, the economics really only stack up as a cottage industry 'on the side' - If I added in a cost for my time, at say £10 an hour, I would probably be adding on something horrific like £6000 to the total, so I would never break even if I included that.

bmthtrains - David Posted August 7, 2013 Author Share Posted August 7, 2013 A spare bit of time today, and I've started playing with an idea for another wagon design. Not very far on yet, but can anyone guess what it is? David Link to post Share on other sites More sharing options...
bridgiesimon Posted August 7, 2013 Share Posted August 7, 2013 Tis the large nuclear flask wagon used down to Devonport isn't it? If so, I am VERY interested!!! http://www.tauntontrains.co.uk/images/2010-SEPT/37059-10-09-10-6Z71-CREWE-DEVONPORT-40STEPS-SY.jpg Most excellent start by the way!!!!

Wild Boar Fell Posted August 7, 2013 Share Posted August 7, 2013 Hello David, The future plans sound good, is the 75t Crane the telescopic one? If so I think the new Peter Tatlow book will be invaluable to you. The IQA is looking good too, you have made my common mistake though, and put the product name as the render file name which makes it easier to guess. Keep up the good work, Regards, Wild Boar Fell Link to post Share on other sites More sharing options...
Etched Pixels Posted August 7, 2013 Share Posted August 7, 2013 (edited) Devonport flask would be very interesting to me too ;-) especially as it seems Bachmann are issuing the Mark 2 squaddie coach that goes with it.

bmthtrains - David Posted August 7, 2013 Author Share Posted August 7, 2013 D'oh! Anyway, here's how its looking 2 hours later! David 3 Link to post Share on other sites More sharing options...
bmthtrains - David Posted August 7, 2013 Author Share Posted August 7, 2013 There seem to be 2 similar wagons, the IQA (which is what I am modelling) that comes from France, and the KVA (which Simon's link points to). As with all nuclear wagons, there is scant information available on them, and I've not been able to find any photographs from the top, so the ridged surface is purely my invention, no idea what it looks like from above! As the aforementioned DRS Mk2 coaches are going on sale this month, I was going to get a pair anyway, so decided I'd like a nice wagon to go with them...

bmthtrains - David Posted August 8, 2013 Author Share Posted August 8, 2013 Hi Andy, The second link is to the KUA wagon which is quite different. Thanks for the first though! David Link to post Share on other sites More sharing options...
andygif Posted August 8, 2013 Share Posted August 8, 2013 I put the second one up for the others to see the difference really.... but glad you liked the first. I've got the 00 MJJ wagon kit to "shrink" for N, as the 12 wheeler version, in my todo pile. Struck trying to get the standalone flask done first. (small children and broken laptops are not helping!)

bmthtrains - David Posted August 8, 2013 Author Share Posted August 8, 2013 While waiting for the TRT to soak, I've done some more to the IQA wagon - this will be a treat to myself for surviving (I hope) the INGS! David 3 Link to post Share on other sites More sharing options...
alibuchan Posted August 8, 2013 Share Posted August 8, 2013 This wasn't on the list Might need a pair of these now. Alistair Link to post Share on other sites More sharing options...
bmthtrains - David Posted August 8, 2013 Author Share Posted August 8, 2013 Back to the TRT, and here are the two sets of wagons together. Given you realistically need 2 sets of the sleeper wagons, that adds another 6 wagons to the length. I'm going to need a bigger layout... David This wasn't on the list Might need a pair of these now. Alistair Ah but that's the problem with a list - I get a few spare hours and something else appears! David 5 Link to post Share on other sites More sharing options...
bmthtrains - David Posted August 8, 2013 Author Share Posted August 8, 2013 I've sprayed the wagon with primer now, just need to sand down a few rough areas and tomorrow I can spray the base yellow colour. With the primer on, the detail is really coming out well. David 6 Link to post Share on other sites More sharing options...
bmthtrains - David Posted August 8, 2013 Author Share Posted August 8, 2013 Priming is now done and the correct bogies are now in place. I'm quite relieved this has come out okay without needing any modifications to the designs as its a tad expensive one to make mistakes on!

shanks522 Posted August 8, 2013 Share Posted August 8, 2013 Yet more excellent work David, will the TRT negotiate curves? Graham. Link to post Share on other sites More sharing options...
bmthtrains - David Posted August 8, 2013 Author Share Posted August 8, 2013 Thanks Graham, Should go round 11inch curves maybe tighter, will test on Cross Street but I can't see any issues cropping up, each section has a very wide arc of movement, and the only limitation is the long wheelbase on the main 'action' wagon.

porkie Posted August 8, 2013 Share Posted August 8, 2013 Oooh David, This has to be the best thread on here, love the Work you have done so far. Deffo put me down for the nuclear wagon. Will you be doing a QKA pocket wagon in the future as these seem to like hens teeth in our scale? Link to post Share on other sites More sharing options...
Wild Boar Fell Posted August 8, 2013 Share Posted August 8, 2013 Hello David, Good work with the rest of the TRT, it is looking superb as does the flask wagon. I remembered that I had found this image a while back so I thought it may be of use to you. http://www.bdca.org.uk/gallery/index.php/Miscellaneous-Images/Basic-Data-and-Dimensions-for-75-tonne-tele-jib-cranes/CARKND-CODEJZIB Regards, Wild Boar Fell Link to post Share on other sites More sharing options...
RMweb Gold Revolution Ben Posted August 8, 2013 RMweb Gold Share Posted August 8, 2013 Hi David Great work on the TRT - looks fantastic and it's sheer size emphasis one of the benefits of N. As for the flask wagon, it looks great but I can't quite make out how you have pivoted the two end chassis (with the bogie pivots on) from the main body of the wagon. The clearance - especially toward the centre of the wagon - looks very tight! cheers Ben A. Link to post Share on other sites More sharing options...
bmthtrains - David Posted August 8, 2013 Author Share Posted August 8, 2013 Hi Ben, At the moment they're aren't pivoted - it's just two bogies next to each other as per the real wagon (from what I can judge in photos). I'll need to test what this means in terms of going round model curves and then work out the best way to give them free movement. David Link to post Share on other sites More sharing options...
Etched Pixels Posted August 8, 2013 Share Posted August 8, 2013 First thought would be that if you mount the second bogie on a piece of thin metal strip pivoted off the bogie at the join (ie off the same mount and the bar able to rotate separately ditto the second bogie) then it ought to go around anything. Might look a bit odd on a 9" curve but it ought to traverse it fine. Link to post Share on other sites More sharing options...
bmthtrains - David Posted August 8, 2013 Author Share Posted August 8, 2013 (edited) Forgive the crude drawing, but I think you are describing the second option here Alan? Having not experimented much with this kind of set up, is there any benefit to either version? Does one give better movement than the other?
