  1. Congratulations We could start a thread about Trophies
  2. It wasn't a warping problem it was the soft board used as an underlay for the cork This that I am referring to takes us back to 1990's not present day, the board that was used is hygroscopic, expands when wet, on one occassion we had stock falling of the track when going through one of the main turnouts of the layout, what had happened was during storage the area under the common crossing had got wet resulting in that area rising so that the common crossing was higher than the stock rails Their is still a board on the market that is referred to as soft board use for insulation and sound proofing Geoff
  3. When I say soft board I am not referring to Sundeala, Sundeala is a different animal compared to what I was referring too and is a lot better quality and more expensive, and comes in at least two different grades I can't remember any other name for it than soft board it is brown and soft unlike Sundeala which is grey and dense Geoff
  4. Looks like Mark has an itch that needs scratching
  5. Two off them opposing, could be one either end, just be wary of point motor fitment
  6. A large flat area of ply will not stop the boards from twisting, you can only stop twisting by adding diagonal bracing. Before fitting diagonal bracing which will hold it all square and stop twist you need to ensure that it is square and not twisted when you fit the bracing, otherwise the twist will be always their and you would need to remove it and try again
  7. I think you may have forgotten about the construction of New Haden, the initial deck that the track is laid on is large panels of 3/8" plywood covering all the baseboard area, these large panels initially forming the contours of the layout, where the track was to be laid the ply was first covered in 1/2" notice board material ( brown sh1t soft board ) then covered with cork. It was the 1/2" notice board material that caused any undulations in the track bed,caused by being held down with large weights when fitted and the layout later being stored in a damp wet atmosphere causing the notice board material to expand when it got wet, the large weights causing depressions, the depressions being leveled before I laid any track having removed the previous track work, Levelling the track bed out is something that I have had to do on another layout recently
  8. Chuntering Cobalt now changed, the supply voltage had to be as low as 6v before it would stop chuntering

      I run mine on around 9v, had a few swap outs...

      Are tortoises any better? I'm at a point where I'm looking at point motors & I keep hearing things about cobalt clunking. Is there any benefits over tortoises using dc power ?

      The tortoise although bigger is a better buy and definately more reliable than the Cobalt

  9. If the middle doesn't make a bid for freedom by going up it will be the ends Geoff
  10. Your trainset you can make as many executive decisions as you want too Why have a flat boarded area at all.
  11. The version with the dials posh one is £95 Whichever version you use if you are doing a lot of rivetting you will need to mod the handle to make it more comfortable to use (feedback from other users) Geoff
  12. I suspect that the 2000 lumens of one set and 270 lumens of the other set are being compared incorrectly The one that specifies 2000 lumens is for the full 5M lenght and the one that states 270 lumens is per metre Geoff
  13. The lights on Black Country Blues are not Blue and give no blue effects with photographs, yet the colour temperature listed on the bulbs is 6700K, seems confusing Geoff
  14. No website available, it's G W Models 11 Croshaw close Lancing West Sussex BN15 9LE 01903 767231 Advertised in MRJ Geoff
  15. Need to change a troublesome cobalt point motor on BCB so we can have less chuntering

      Can I suggest a small accidental fire????

      Bought a multipack from a well known box shifter, 3 didn't work on DCC. Sent them back and all 3 replaced no quibble. One returned motor still a problem. Sent it back and got a new Classic Sigma in return. Now happy :)

  16. I won the best layout award @ Expo EM North

      Are you really P4 as you look quite normal.

      I'm told you can get quite a lot of trackwork on the average bloke's back, providing he lies down and keeps perfectly still.

  17. Having a tow bar on a boy racer car wouldn't do anything for your street cred
  18. Is that the height gauge which is used to set the height and centre line of the coupling, which is 10mm above the rail head which is the same as the ones I made for the EM AJ couplings but to a different track gauge Geoff
  19. All your sage advise did, was to get me to do more posts in a day than I usually do in a month. and the man that falls asleep on the stool on his stand thought that your advise was useful, which part I wonder
  20. It will put unwanted stress on the servo if the twich is driving the servo hard against the limit of travel (the rail )
  21. Shielding the magnetic field won't stop the problem it is the back emf voltage from the coil in the wiring you also need mu metal to shield a magnetic field. if you were to wrap some metal around the coil you would be creating a secondary winding for the coil which is a shorted secondary winding which would burn out the coil
  22. When you operate the coils you create the magnetic field' which then collapses when you release the button, this collapsing of the magnetic field creates back emf voltage, the voltage it creates is what is causing the interference, adding a diode short circuits the back emf,
