  1. First reason: many many years ago (47 probably) I had a 2’ radius curve with IRJs (not that I knew what an IRJ was then!) and whilst they kept the rails in line they still had a sharp kink on which a Hornby (probably Tri-ang Hornby) plate wagon would derail. Second reason: to maximise standage in what will be the yard headshunt I wanted a measured clearance point so I had to wait until all was laid before cutting the rails. We live and learn and I have a plan! Paul.
  2. 1. To give it a try as others have used it. 2. Limited (largely) to non scenic area so ballasting won't make it solid to the board again (a bit sound quality, but as I have lots of separate boards and on each join the rail is soldered to a screw I'll still get noise). 3. Wickes have stopped doing the pre sealed cork and I was struggling to find some 3mm thick to match what I have on the (to be) reused boards. True, but not desperately helpful! Paul.
  3. OH DEAR (2) I've managed to strain my back - possibly the cumulative effect of a few things that have put extra stress on it. Any way, working on boards is Off for probably the next six weeks or so! I am getting caught up on other tasks, like posting here (!) and updating my inventory. I'll let you know when things improve and something photogenic happens. "I may be some time." Paul.
  4. OH DEAR (1) Having run beautifully when the Little People came, when I turned the board back over after doing the wiring 'properly' I saw this: I've laid and cut on curves before with no problems, but its been on cork not foam. I'm wondering if the flexibility of the foam has allowed sufficient movement for the glue to fail in shear. A quick bodge and I'm hoping this will be sufficient lateral restraint. I have another two section gaps on this board - screws will be applied as if it is crossing a board gap. If the bodge doesn't hold a bit of lifting to insert screws under the rail head will occur. Paul.
  5. Of course, sorry. Paul.
  6. Look on Little Muddle as Kevin has covered that before. You’ll need to do search as he has rather a lot of pages! Paul.
  7. Bin there done that! It’s a good solution. One word of warning, having cut the top rail off mine the side legs can splay out. I assume because the middle rails are not glued in place. So . . . add some glue if you go past the bottom rail, or try to pin with a crossed pins (though they don’t go far into the leg) or add your own rail from (say) 4mm ply. Paul
  8. Nice introduction, busy boy! And an excellent cameo piece from Mike. That the one thing in sound that often doesn’t feel right, the rev rise before any movement, falling as the governor kicks in and then rising as the train moves off. (It was especially characteristic of class 47.) Well done. Paul.
  9. Unfortunately, after the date of this layout. Paul.
  10. Would they be droppers though? Risers surely! Paul.
  11. Not had that problem myself, but your explanation makes sense. Paul.
  12. I think you could have tomato with your cheese. Paul.
  13. Another vote for curved points, and they do look good. I have seen ‘worried’ comments about curved points, but have never had any issues with mine (PECO code 100 electrofrog). Photos of the curved points are in the earlier part of my Heath Town thread. Paul.
  14. TERMINOLOGY WARNING !!!! I don’t think anyone is suggesting twisting cables from different systems round each other (I certainly hope not) as that will increase interference (cross talk) simply by making them closer together, exactly as you warn against. What I’m doing is twisting conductors together (sometimes by default in the mains cable I use). The way that reduces ‘transmitted’ interference is that the current goes out and comes back in much the same place so that one conductor generates the opposite field to the other. In effect, it’s to try to stop the single turn transformer effect. As far as I am aware, it doesn’t rely on differential inputs. Paul.
  15. On Trelothen, no! Distances are far too short to worry. Neat and tidy is the secondary reason why I twist droppers together - it makes it so much easier to see where they go. Paul.
  16. I was thinking about a temporary lash up (sky hooks, bamboo pole, etc.) just to see if the problem went away before committing to something time consuming. From reading the NCE page on cabling, it looks like your OK using 3rd party cables as long as it’s not the pro cab your using. In the UK, 6p4c RJ11 type cables are very cheap got from the right source. Paul.
  17. Had forgotten about that aspect, ‘cos I’ve done that religiously on my track bus. Digitrax have a thing about their loconet not being twisted because that alters the characteristics of the transmission line, I don’t know about power cab. So on Heath Town I’ve relied upon twisting the DCC bus to reduce the radiated interference. Interesting point in Mark Gurries page about not twisting after train detection: I haven’t had a problem with false detection even though I’ve twisted. Thus far my max distance is probably c.1.5m. Next stage has some track sections 9m long, be interesting to see what happens there. Paul.
  18. Something to try if the rod is rotating in the solenoid is to put some glue on to hold it in place. Others may be able to suggest something suitable, and care will be needed to make sure it doesn’t go too far and glue the solenoid solid. Paul.
  19. Yes please. Yes! I’m thinking of reporting you to the SPCS (Society for the Prevention of Cruelty to Signals.) :-) Paul.
  20. Agree about keeping the cab bus away from track and accessory bus. Less sure about ‘straight’, but would add cross at right angles. Not being NCE but extrapolating from Loconet, I assume that the cab bus has to go to all controllers and mini panels. As a possible test methodology, could you reroute the cab bus aerially so that it is nowhere near anything dirty. Think cab bus = signalling, track bus = traction. There is a reason why we want to keep away from your nasty dirty electrons! :-) Paul.
  21. Easy if it’s on a separate output. Most of mine are wired to the opposite end headlights so I will need to go in and mess with PCB tracks. Paul.
  22. A lot, yes, but quite a bit wasn’t and even more isn’t. Penzance was mostly colour light before the 80s, other bits have gone since. So, obviously, your bit is one that went early! Paul.
  23. It shows that the pan is in contact and not just for ‘show’. As far as ‘tensioned’ goes, it’s certainly a word I use. Paul.
  24. 1987/88 WTT 6M16 and 6E36 were a train of 10x73tonne insulated tanks conveying edible oil from Van den Berghs Purfleet site to Bromborough. The tanks had stainless steel heating tubes to prevent the oil from going solid! Paul
