heavymetalwagons Posted November 9, 2021 Share Posted November 9, 2021 a couple of years ago i built a load of coil j's in 4mm and from at least two articles was informed the sides should be 6 to 6.5 mm high then i picked up this of ebay aaaaaaaaaaaa and as we see the drawing says the body should be 700mm high 27.5inches which would work out at 4mm scale at 9mm high !! . at first i panicked thinking i'd built them all wrong but after thinking a bit the coil j's and coil c's ran together and in the photo's look to be almost the same height (well not 200mm /8inch difference) plus again looking at paul's wagon photos the data panels seam to fit better on a 6mm high side and look wrong on a 9mm high side so i think the drawing wrong .have they measured the total height including the solebar which would still make the overall height still wrong !! anyone got any better ideas !! please help many thanks all Link to post Share on other sites More sharing options...
RMweb Gold ikcdab Posted November 9, 2021 RMweb Gold Share Posted November 9, 2021 Looking at Paul's pictures, certainly the proportions are nothing like your drawing, so your 6mm seems better. If you get a decent side-on view, you could use GIMP to test it against your pics and determine it definitely. Link to post Share on other sites More sharing options...
hmrspaul Posted November 9, 2021 Share Posted November 9, 2021 I wonder if the confusion is with the unique KJV https://PaulBartlett.zenfolio.com/brcoilj/e269b254a It is unlikely to have been an important measurement for BR. BR diagrams are not suitable for modelling. Paul 1 Link to post Share on other sites More sharing options...
Ruston Posted November 9, 2021 Share Posted November 9, 2021 I built some of these last year. I also found that diagram and dimension. I discounted it and scaled the height of the sides off known dimensions by downloading the full size version of one of Paul's photos from his website. I think I made mine to 7mm high. 2 Link to post Share on other sites More sharing options...

BR diagrams are not suitable for modelling. Paul Was also thinking if it was that wagon but the drawing says sjo and the experimental one is vacuum fitted. But if it was that wagon could still be of use as i liked the idea of building that one. Was hoping you'd reply paul as you're the wagon master and if anyone could figure it out it would be you Thanks Link to post Share on other sites More sharing options...

One of the reasons i built mine was quite a simple build. But the weathering versions was the thing that stood out for me Link to post Share on other sites More sharing options...
Mark Saunders Posted November 10, 2021 Share Posted November 10, 2021 This has again raised the difference between diagrams and drawings! Diagrams are for use of Railway Staff Drawings are for Railway Modellers! 1 Link to post Share on other sites More sharing options...
