  1. I would change the last line to: "Something wicked, disappearing into the carpet, that way went!"
  2. So what if it does duplicate the 7mmNGA? As a member of S7, G0G and 7mmNGA, I have no problems incorporating elements of narrow gauge railways in standard gauge layouts and dioramas. How else might you model the two adjacent stations at Minffordd ?
  3. Yes is the short answer. The criteria is 7mm modelling - Track gauge whether Broad, Irish, Standard or Narrow is irrelevant.
  4. It is probably worth pointing out for the sake of clarity that the Gauge 0 Guild does NOT have any branches or affiliated clubs. It is simply an international organisation of individual 7mm modellers who receive a quarterly Gazette [i.e., magazine] and which organises three annual shows currently at Telford, Kettering and Doncaster for its members. There are 0gauge groups within many local model railway clubs nationwide and, individually, some of their members may also be members of the G0G. It is not unknown for the G0G to offer grants to some clubs towards items such as 7mm test tracks but these clubs are not part of the Guild. Organisations such as the Guildford Group and Bristol 0 Gauge Group are not part of the Guild though may well have received start up grants from the G0G for their trade shows in the past. That their shows thrive clearly suggest that 7mm modelling exists both within and without the Guild. Thus for correspondents in this thread to have said that G0G 'groups' have not made them welcome is a fundamental misrepresentation of reality as no such 'sponsored' groups exist. Indeed an invariable condition of the G0G giving a grant to a 7mm team inside a local MRC is that all are made welcome to use the facility [such as a test track]. If someone has been made to feel unwelcome at one of the three G0G organised shows, then that is quite a different matter and IMO unforgivable.
  5. Excellent model maker as well as past chairman of the Gauge 0 Guild technical committee. His G0G Gazette articles on basic chassis assembly, Slater's wheelset preparation and many other topics beginners were afraid to ask about , were models of clarity. More recently, I was involved in designing elements of his planned GT3 model - notwithstanding the dreadful chronic illness that he suffered from and which finally took him from us. RIP Bob.
  6. No Tony, it isn't. Resins like Fullcure 720 are derivatives of cyanoacrylates. If you take a spare piece and attack it with a piercing saw or Dremel slitting disc you can smell the "bitter almonds" aroma of cyanides. The polyurethane resins are the sort of resins that Crownline, JLTRT and Radley Models use in their kits and as you know they are cured in the same way as epoxies - by reaction between two components as opposed to UV light/laser in the case of the cyanoacrylates.
  7. Yes, the suspension units were designed by Acton works for BR(S) . They were essentially copies of the 1956TS boxes and suspension but for financial reasons, fitting wasn't completed until sometime in the early '60s. Full details are in John C Gillham's book on the W&C Railway (Oakwood Press, pp291 et seq)
  8. Perhaps not technically LT but certainly London underground rolling stock. Soon to be available from Radley Models will be a 4mm Class 487 Trailer Second car. This will be followed by a 4mm DMBSO in its post-1956 form i.e., with the LT-designed axle box fittings. BR olive green, a sort of electric blue and NSE livery are all possible for these cars. Coupled to a suitable match wagon, they would be appropriate vehicles parked in a siding anywhere between Waterloo and Eastleigh.
  9. Apropos nothing whatsoever, there is a precedent for an absolutely spotless long train of brand new 16T minerals. I have seen a published photograph of a [dirty] WD pulling a whole trainload out of the Pressed Steel plant [?in Renfrewshire] where they had been newly built. I can't recall where the photograph was now sadly.
  10. The problems with ultraviolet light cured 3D print resins are well known but, frequently IMO, ignored or denied. Of the half dozen or so methods of 3D printing, only three are readily used by home printers - Fused Deposition Moulding where a PLA or ABS thread is heated and molten mass deposited along a track and then the process repeated to build height. This tends to work well on slab-sided models but cures leaving stratification lines which are difficult to remove. However FDM models are pretty robust and do not decay and become brittle. Selectiive Laser Sintering [SLS] models are powder surfaces which are heated by a laser and fused in particular patterns. A fresh layer of powder then covers the fused area and the heating is done again and eventually a model is built up layer by layer with the unused/unheated powder finally being removed. These are quite rare now but were very popular in technical colleges 15 years ago. Because they are produced by laser light, they do slowly denature in white light. The third form, often called resin printers are technically called SLA [Stereolithography] or DLP [Diode Light Projection] printers. The only real difference is whether the light source that selectively solidifies the surface of a tank of liquid resin is a laser or an LED. These printers produce very smooth surface finishes and are used by many home users and industrial concerns. However, because the resins are light cured, the models continue to cure [whatever the manufacturers say] for some considerable time after printing. In practice, this means these models become brittle. Some protection may just possibly be obtained by painting the model so that the light doesn't get to it but that isn't [in my experience] to be relied upon. In my opinion, the bottom line is that If you want a 3D printed model to last for as long as an injection moulded model, then the 3D print should only be used as a master for polyester resin, [white-metal and/or lost wax] casting. Such polyester resin castings are generally pretty robust and do not denature in daylight.
  11. Soon to be available from Radley Models will be a major modification to a previous 7mm scale Radley kit. I've taken my previous Mk1 Ford Thames Trader cab and digitally cut and pasted it so that it is now a crewcab version. A new chassis, box body, rotating beacons, LT URGENT signage and new grille complete the model. Design work is complete and a few masters remain to be printed and then it's off to CMA to be cast in resin. The prototype was last seen at Castle Point Bus Museum at Canvey Island and I assume is still there. Attached is a picture of the 3D print of the bare cab and box body.
  12. London Transport breakdown crews used crewcab Mk2 Ford Thames Traders with either a box body or a half length canvas tilt. Some of the latter might also have had a CALM-type crane attached. Similarly LT also used workshop/crewcab bodies on Leyland PD3A bus chassis. I imagine that BR would have had similar crewcab vehicles. An example of the Mk2 TT is shown here - but in 7mm. Wheels/chassis etc., designed but not yet printed.
  13. As a committed [if not actually sectioned under the Mental Health Act] fan of matters LT, the idea of producing a 7mm version of the Met Rly's 0-6-4T rather appeals. hence my interest in what other railways used that wheel arrangement. Once I have finished Tony's Marsh C3, I might have a go at a J tank in 00/EM.
  14. Thank you all for your assistance Arun
  15. Greetings A friend in Brockenhurst contacted me this evening regarding a local footbridge which seemingly had lost its number plate. This is not the new footbridge and lifts at the station but the one indicated in the map segment below at Grid Ref SU 30051 01898. This forms part of a footpath and continues on the southern side of the railway and is the first footbridge passed heading South West from Brockenhurst to Sway. The question was really, whose responsibilities are these bridges? - Are they Network Rail's responsibility or the local council's?
