  1. I once knew someone who managed this in P4. He used strips from a plastic milk bottle to make the spring leaves.
  2. Like this? Found in the detritus on my bench, other sizes may be available.
  3. Or maybe, because they have decided to replace the head spans, they've realised they can't do it one line at a time.
  4. ...and the one behind is a B12/3 - another Gresley Thompson re-boilering of a Great easter Railway design. That's better...
  5. Do you reckon the coal would still be there by the time they started dredging?
  6. That is one thing that has not happened, maybe because it needs proficiency in CAD that is difficult to obtain quickly. Companies are working on machines based on the techniques used in offset litho printers, which might be the way forward.
  7. Are you not including curve radius in your calculations?
  8. Not difficult, you just need a pair of these: https://www.cousinsuk.com/product/half-round-flat-nose-pliers
  9. There are not enough customers to make taking wagon kits to shows worthwhile. Or at least too many potential customers have bought themselves Leeds trousers. You know the ones where the pockets are too tight to get their wallet out.
  10. I believe that Colin Seymore is now the only manufacturer of steel buffers, so you will have to wait until he finds his round tuit.
  11. The one thing that will change this is the ability to print with a coloured surface layer, allowing liveried models to be produced. It is possible to do this now, but the material used is not particularly robust. It's fine for static models but has problems with models that are likely to be handled.
  12. Ah, so. The feminisation of society has caught up with model railways?
  13. Here's a clue: The ratio of the actual to expected dimensions is 1:0.57, almost the same as 7:4. So the error appears to be in the CAD.
  14. Stl files are undimensioned. So your problem may have to do with what your CAD software is outputting.
  15. If it's being modelled after nationalisation it is likely to have had disc wheels.
  16. You can find them on the new website: https://prototypecouplers.com
  17. These are grease axleboxes. The brass bearing are coloured yellow in the sections of both drawings.
  18. Yep, you're right. I checked with the sketches of axleboxes in Midland Wagons and the 10A is 3/4in higher than the 8A from the axle centre to the top of the casting.
  19. Except Gorton seems to have provided Gloucester with components for these horseboxes, i.e. the unique axleboxes and possibly other ironwork. I don't suppose we will know unless someone looks into the relationship between George Edwards and the GCR.
