  1. John, A small change but a big improvement. Dave.
  2. No idea what it is or what it does, but looks suitably complicated. Dave.
  3. David. The layered static grass looks very effective. The shots of the layout are wonderful and you are certainly capturing the atmosphere and look of a country railway. Does look like a bit of vacuuming of the track might be required. Dave.
  4. I built a High Level chassis (in EM for Pendon, body by Guy Williams) for a pannier and can say it went together very well indeed. Dave.
  5. David. I see you managed to pick this model up at a very good price, but I suspect it was originally much more expensive. Bearing that in mind, the Bachmann locos stand up pretty well in comparison. Dave.
  6. David, Those are pretty cruel enlargements and, to my eyes at least, it looks a very fine model. I was very impressed by how well your re-wheeled Jubilee ran on Barrow Road - better than my Brassmasters based version, much to my dismay. It goes to show that provided the track is well made and laid, simple conversions to P4 can work reliably and smoothly. Dave.
  7. All looking very impressive, indeed. I had been wondering if the walls had a plinth, seeing the stone work finish short of the bottom of the door openings. Looking forward to seeing further progress, Dave.
  8. Can't be a WD - the eccentric rod has a roller bearing at the return crank. The expansion link support is wrong for an 8F. Something Eastern, perhaps? Dave.
  9. Very nice, Robin. I didn't know those brackets are called holderbats. Never too late to learn something new. Dave.
  10. Dave. Yes, you're right. The twin beams rest on top of the axle-boxes when they are in their mid position. I would reduce the parts of the beams which rest on the boxes to slightly less width than the axle box and radius the bearing faces so that the beams do not try to tilt the axle-boxes in their horn guides when the beams tilt. You may need to put a slight set in the beams so that they just clear the inside face of the horn guides and do not rub on them. Use a spacer tube to hold the beams apart and close to the frames. You need a very small amount of clearance to minimise friction, but not so much slop that the ends of the beams can come off the top of the axle-boxes. I hope this doesn't sound too complicated because you'll find it fairly straight forward in practice. Dave.
  11. Dave. I have two 2-6-4 tanks - a Fairburn (DJH) and a Stanier (Gibson) in P4. The Fairburn, one of my first locos has a fixed, driven (Portescap) front axle and a single compound rocking beam arrangement for the rear two coupled axles and the centre of the rear bogie. The Stanier has a better, and in my view, simpler arrangement of twin beams for the front and centre (driven (Portescap)) axle and a single beam for the rear coupled axle and the bogie centre. In both locos, the front truck is sprung. If I were to make another 2-6-4, I would definitely use the same arrangement as the Stanier tank although, to be fair, they both hold the track as well as each other. The fixed axle on the Fairburn does make it lurch on bad rail joints, whereas the fully floating Stanier glides over. Hope this helps. Dave.
  12. David, Your trial post and signal assembly look very good. Being able to print the lamp and bracket integral with the post must be a great advantage of this method of production. Signals are yet another aspect of railway infrastructure that helps place a layout, both geographically and in time, even when no stock is present. Mind you, it wouldn't help me place your layout as I have no knowledge of railways of that area. Looking forward to seeing further examples as they come along. Dave.
  13. David. It's all looking very nice indeed. Regarding the facing lock mechanism, if you want the lock to be visible, Ambis do a very nice etched version. Otherwise, you can hide it all under a ramp type cover. On mechanical rodding FPL's, there was usually a detector bar on the inside of one of the rails to prevent unlocking if any stock was standing too close to the point switch. Hope you don't mind, but here a some photos of how I represented this on my Holt layout. It was ex-LNWR so the arrangements might not be quite right for your location, but the principles probably apply. Overall arrangement with FPL to the left and the fouling bar drive to the right. The bar is inside the lower rail. FPL with drive and representation of point blade and lock detector rods. In this case, the FPL was actually moved by a connection from the detector bar, rather than direct from the signal box. Thus, if the bar was broken or became disconnected, the FPL could not be moved and the signals not pulled off. Fouling bar moved from the far end so that a broken bar does not give false indication. Spring device took the weight of the bar to reduce the effort needed to operate. The bar itself, was made from brass angle with the Ambis cranks soldered on using a simple card jig. To plant the bar, pegs were attached to push into holes in the cork underlay. I had to cut off the bottom of the cranks to get the bar to sit at the right height, so as not to catch on wheel flanges. Unlike the prototype, my bar is not attached to the rail. Hope that gives you some useful ideas. Dave.
  14. John, Good point about the level of detail versus location on the layout, but it does seem a lot of effort. I'm particularly impressed with the pipe flanges and clips and the super-fine sanding operating rods/linkage. Dave.
  15. David. Point rodding makes such a difference to the overall presentation, in my view, so it's looking good so far. Have you included representation of the compensators - none visible in the photos? Dave.
