StuartM Posted July 13, 2012 Share Posted July 13, 2012 I built this transparent test truck as an aid to building my own 2mm track as being able to see what is happening at the rail to wheel interface is incredibly helpful for finding those annoying tight spots and other such problems associated with poor running. Its an idea that could be rescaled to any gauge and would even be helpful to people using rtr track This project is now complete! Link to post Share on other sites More sharing options...

34theletterbetweenB&D Posted July 16, 2012 Share Posted July 16, 2012 Good stuff. Now, was that a controlled amount of skew you built into the test rig as a 'worst case' stress, or is this an artefact of the photographic system or software, or just my screen's rendering? (I am wearing specs that compensate for my personal ocular system's astigmatism...) Either way it opens an interesting discussion. Never forget that anything built for this kind of inspection/testing purpose ideally should not introduce any problems of its own; and an order of magnitude more precise than what is being inspected is desireable. Or,assuming the transparent test truck to be 'all square' in actuality (I am sure it is), please note that 'the camera' - this of course nowadays including all the occurences in the digital domain between the input and output imaging stages - can and often does 'lie'...

StuartM Posted July 16, 2012 Author Share Posted July 16, 2012 Available now at a mailbox near you! http://www.micromark...heels,7895.html Nice!, However the truck in your link has a bo-bo wheel arrangement, whereas my truck has a "co" wheel arrangement or in old money 0-6-0 which I did on purpose because I wanted to see if my class 04 shunter would traverse the curves, frogs and check rails that I've made. I've found from experience that a 4 wheel truck will quite happily run through trackwork designed for a shunting layout but when you try and get the 6 wheel shunter to run through the same trackwork, quite simply.....it won't!. So I made this 6 wheel truck purposely to test my track for not only shunters but also for co-co locos eg: 31,37,47,50 etc. With regard to the post by 34theletterbetweenB&D, I'm afraid I have no Idea what your talking about, however should any manufacture take my idea on board I think it would be an excellent idea to make the plastic optical in such a way that it magnify s the wheel/railhead for easier viewing. Perhaps that is what 34theletterbetweenB&D was suggesting? Incidentally I got the idea while working on this http://www.rmweb.co....de-slip-in-2mm/ Link to post Share on other sites More sharing options...
StuartM Posted February 13, 2013 Author Share Posted February 13, 2013 A short video showing the merits of my Transparent Test Truck, You'll notice the shunter is more footsure than the truck but the truck tends run more smoothly with the weight of Gods hand pushing it through the track work, still the video gets the point over Link to post Share on other sites More sharing options...
RMweb Gold Oldddudders Posted February 13, 2013 RMweb Gold Share Posted February 13, 2013 Thinking back to shortly after the Ark scrunched up onto the shore - do I recall something in Railway Modeller called "Sharman's Scrutable"? Mike of that ilk obviously thought the idea had merit. Link to post Share on other sites More sharing options...
Armchair Modeller Posted February 13, 2013 Share Posted February 13, 2013 How do you find it when it falls on the floor? Seriously, seems like a good idea! Link to post Share on other sites More sharing options...

I built my 2mm track before I converted any locomotives and decided to use a bogie wagon to test with which worked perfectly. I also used a four wheel wagon and this ran as well even when tipping the board up so that it wasn't being guided by my hand. When I finally got my class 24 converted it wouldn't run through most of the points and I had to adjust them. I feel this would have saved me a lot of time.
