  1. It's a back to back gauge that they are talking about, not track gauges I'm in the process of doing some but they not started yet, waiting for this xmas event to get over and done with Geoff
  2. Where's the disagree button Geoff PS the quotes work in Edge but not IE11
  3. If you suggest Y's and tandams you will need to convince him of doing other crossing angles than 1:8 Geoff
  4. Yes we did, and the track department was forever removing it from his clothes and getting cursed for walking it into the house Geoff
  5. Having held onto it, it's now Tackeroo's or Fryers Lanes job to hang onto it in 2016 Geoff
  6. Are you going to equalize the timber spacing and have all ends in line Geoff
  7. well if you study the photo's you will see that the prototype checkrail only spans 3 timbers, keep up Geoff
  8. Not trying to compete with Mark I have here a 1:8 turnout with a 10' switch specially done for the L&B by John Clutterbuck o14_master_pages_2015_12_01_2049_49.pdf Templot box file o14_master_2015_12_01_2000_41.box Enjoy, all you have to do now is build it Geoff
  9. The angle will be correct, but your photo of the switch and the jig shows what is wrong, the length of the 014 turnout needs to be shorter it's back to the drawing board. Did you read that article by John Clutterbuck that Mike sent you a link to in the other thread ? Geoff
  10. It will be the planing angle that is wrong, you need to check the planning angle of your jig and the planning angle of the Templot switch on the drawing They need to be the same eg is it A, B, C, D, etc switch
  11. Have to agree with Mark, you need to fit individual shims between the rail and the pcb But how are you going to maintain the gap is consistent so that the rail is level so you don't have wavy track, and adding weights to hold the rail in place just makes it worse Filling the gap with solder will put more heat into the rail and pcb which could lead to rail expansion or delamination of the pcb Geoff
  12. No, I think I was more interested in the road
  13. Short cuts, I'm still trying to figure out how we got there, I'm sure the van I was following didn't know either, seemed to take forever Geoff
  14. Post it up north then, to indomitable with some chilli
  15. You mean more annoying than before, where's the off switch
  16. Work! their plastic, will melt if you give them some work to do Geoff
  17. Following on from Wagonbashers post above here's some information about the coal hoppers on New Haden Collery, being that this is built for 4mm/ft you will need to increase it's size to handle material ( coal ) for your scale It uses a rotating disc at the mouth of the hopper with this you can Stop and start the flow by stopping and starting the disc Control the amount of flow by controlling the speed of the disc Control the volume by controlling the amount of time the disc is running How does it work? With the disc stationary and the hopper filled, the material will sit on top of the disc, with a small proportion going towards the edge; providing the disc is wide enough it is unable to get to the edge of the disc so nothing flows from the hopper, rotate the disc and centrifugal force will cause the material to be flung sideways from the disc allowing more material to flow from the hopper. The lower hopper catches the material flung from the disc and then directs it through two outlets so that it forms two cone shaped piles in the mineral wagon sitting below The power source is a combined motor gearbox initially designed to run from 16 volts but for this application is being run at 12 volts giving an output shaft speed of approximately 260/270 rpm, this then drives the disc using plastic V pulleys and rubber belt, the v pulleys and belt considered to being a better option than a drive shaft and gears, due to the grit content of the material possible getting inside the gears and causing the drive to stall. The drive motors are being controlled by a relay and 555-timer chip, the chip is wired in a monostable mode, with the start button initiating the motor and the motor then running for a predetermined time set by the 555 timer. The timer when activated runs for about 8 seconds, There are six filling roads on the layout, three underneath each building. The buildings contain one large hopper, which feeds the three roads; Couple of pdf files showing side and front view of the hoppers NHC Bunker front view with text.pdf NHC Bunker side view with text.pdf Main Hopper with two of the drive belts removed Hopper underside Underside of hopper without chutes The individual chutes Geoff
  18. Paul How do you ensure that the axle is square to the wheel, so the wheel doesn't develop a wobble Geoff
  19. How are the bottom doors going to work now !
