  1. The 'adaptor' will amount to an IEC kettle lead, if my experience is still typical. The Nim.
  2. Slightly. To get an optimum traction and track-holding balance you start by considering the relative axle loads. Driving axles for instance provide best traction when equally loaded. The axle loads and their spacings mathematically determine where the centre of gravity will need to be in the completed loco. This may influence the driveline layout in order to provide the optimum placing of voids in which to locate ballast to achieve the desired centre of gravity. In a parallel analytical thread, the axle loads and their spacings, via the spreadsheet, determines where the spring anchors need to be. The technique has been around long enough now for various rules of thumb to have emerged regarding relationships between driving and carrying wheel axle loads, acceptable tweaks to anchor locations, wire diameters etc. The Nim.

    ...Except where Peter Townend was involved! The Nim.
  4. The Independent's summary https://www.independent.co.uk/news/uk/politics/grant-shapps-hs2-heathrow-transport-policy-voting-record-boris-johnson-a9020141.html aligns reasonably closely with what I've observed from Mr Shapps as my MP. The Nim.
  5. Except that it wasn't a passing aberration. The public announcement he made later showed he was, effectively, bearing a grudge. The Nim.
  6. Au contraire; the CL compo lavatory was as characteristically KX as were the Baby Deltics ! LNER vehicles were still in evidence in some numbers too, into 1963 according to my daily travels at the time. The Nim.
  7. Haven't bought any of theirs since it happened! US comic Rich Hall wasn't impressed either, I recall. The Nim.
  8. I note it's not particularly spanner-friendly. Is this design of fishplate 'fit and forget'? And presumably it's located where it is for electrical isolation requirements rather than mechanical? The Nim.
  9. I thought this topic must have been to flag a Peter Snow programme. Possibly fortunately, there'll be one of those along in a few days! I guess they're following his trainspotting format. The Nim.
  10. I wonder if that was related to any requirement to obtain Hitachi personnel to administer safety procedures on the train? The Nim.
  11. How much trial and error was needed to get a functional fit to the axle? The Nim.
  12. Where have the 'resting' 91s been tucked away? The Nim.
  13. BBC London TV News covered this in a brief segment. One of those they had a chat with was a transport museum director who'd come across from the USA to see what his London counterparts got up to. He seemed like a pig in muck! The Nim.
  14. That's a rather smart livery! (Says he from GN territory) The Nim.
  15. I had a Ringfield 8F do that from new. The theory myself and my Dad came up with was the motor shaft bearings chattering. We never did sort it completely, having tried balancing the armature. The Nim.
  16. I'm sceptical; to correct the problem would also require the underframes to be narrowed. The bogies were also over-width, presumably to match or compensate, so they would need modification or risk looking wrong. Putting them right would at last tempt me to buy some though! The Nim.
  17. It looks to me as though those verticals pass behind the bodyside framing diagonal. I'd say they're part of the radiator panel, or its ducting. The Nim.
  18. PU Resin cast from 3D-printed masters? The Nim.
  19. That's rather discouraging. I've been contemplating a 200-odd mile trek there to look for specific EE works drawings, which would require leafing through several bundles of drawings, as the cataloguing to date is pretty superficial. The Nim.
  20. There's also the behaviour of the exposure light in the Photon and similar. As it penetrates the resin, it is scattered and becomes de-focussed. Thus some resin outside the boundaries of the target voxel becomes part-cured. This problem will remain although the higher-resolution LCDs which are in the offing will reduce the pixellation rounding errors. The Nim.
  21. Where is that village? To my eyes it's Cotswolds/Oxfordshire stone. The Nim.
  22. More good news is that the missing innards of the motor bogie are common to the Brush Type 2 bogie, used under that plus the EE Type 3. Those are so plentiful that getting hold of those bits won't be too expensive. The Nim.
