  1. I’m curious to know if you built your own chassis or used an RTR one? I’m guessing from the colour of the bogie frames that you at least crafted those?
  2. Perhaps it was reluctance? Or at least that is what I'd like to think.
  3. I have somehow managed to solder the compensating b frame in at an angle, it's only ever so slight but it's enough that I can foresee problems that I don't want. Coupled with the fatality to my adjustable heat soldering iron I put the project aside until I decided on the solution and CSB is coming back to me more and more but I'm not sure if it's easier just to stick with the compensation beam, as the rear axle is already fixed.
  4. Well I never thought I would be described as a guru! To be fair this still needs to be finished up, I've been trying to work out a problem with my compensated chassis.
  5. I like this. The tender in particular is impressive but the whole thing has a nice feel about it. It looks like the sort of thing you might find on India or Ceylon.
  6. Indeed it would, albeit whenever improving reliability crops up, it's usually followed by standardisation to achieve efficiency so it's likely that there would have been some new builds.
  7. That’s quite an interesting point that I’d not considered.
  8. It is partly my fault that this thread became a bit technical, but for the above reasons. I like to look at what is feasible, possible, plausible and technically acheivable, as well as something with a use. That said, I'm thinking of coming up with a GWR-esqe 4-6-0 with 4'7.5" driving wheels, so I mostly want to be able to bat off any criticism when I do. There has been a suggestion that we look at a Gresley lead LMS, or a Stanier lead LNER on several occasions on this thread, and I know there is another thread for imaginary railway companies but this and/or freelancing are what make this thread what it is. Doesn't have to be one or the other. There's not just those two to consider either. If we are talking about the grouping era, why not think of John Clayton having a greater impact on LMS designs after the S&DJR 7F's. How about Harry Holcroft not going to the Southern, he could have followed Stanier, or perhaps if the LNER had put Robinson in charge to start with, he may have gone there and Gresley may have absconded to the LMS. Bulleid may never have played the crucial part he did and somebody else would have got the job on the Southern. Perhaps that would have been Stanier, Collett, Thompson, Ivatt or Riddles?
  9. Is this where rotary valve gear benefits?
  10. So is the speed of a steam locomotive all to do with piston speed as opposed to wheel size? Or is it that the larger wheel sizes slow the piston speeds sufficiently to kept within tolerances, therefore allowing higher speeds to be achieved over smaller wheels?
  11. I guess Paget was the only one who tried this? so essentially the better balancing allows higher speed, so that could effectively be done with any reasonably sized wheel, so an early suggestion that the Raven A2’s could have used the B16 as a starting point with 5’8” drivers is not unrealistic?
  12. What is it about locomotives with 3 cylinders that allows the use of smaller wheels at higher speeds? Is this a general rule? Does the same apply to 4 cylinder locos? If so, why where there not any small wheeled Pacific’s?
  13. I purchased a Lima class 47 with replacement buhler motor bogie but the motor didn’t seem powerful enough and had a horrible whine so I exchanged it.
  14. This looks really good, and very plausible. It’s a shame this proposal never came to reality, nor the Bulleid and Fowler 2-8-2’s b
  15. Looks like that 4th driving axle is almost in the tender. Would. Lord Nelson boiler not be more appropriate?
