  1. I had thought of that as well, I assume they are double pole switches so contact is made which ever way the turnout is switched.
  2. We have a conundrum - the layout is already built and track laid with a mixture of electrofrog and insulfrog turnouts. The operation of the turnouts is completely manual (BHS) and therefore is relying on physical contact between blade and stock rails to provide electrical continuity. We know this is not ideal but is was built many years ago with little technical knowledge. The turnouts are quite old and therefore do not have the wires that can be cut to separate the blade rails from the frog rails so bonding blade to stock will not be possible. Given the existing situation, what ca
  3. My Amazon package just arrived and included the brass wire cleaner. It has a flux past reservoir at the bottom, how is this used, do I need to heat it and melt the past or.......?
  4. Interesting, I tin the hole by putting thin solder in and quickly heating, tin the wire and then heat the pin again and push in. The problem seems to be I am not using a hot enough tip and therefore holding it in contact for too long. I'll give your version a try next time, thanks
  5. Bit difficult washing control panels & track under the tap So rosin it is for me
  6. Thanks again, order in with Amazon (UK) for all the flux, brass wire and tinning compound.
  7. Thanks for this, but raised a couple more questions. Is the rosin flux no-clean and what did you mean by "tinning compound" for the tip cleaning?
  8. I have done quite a bit of soldering in the past but I've never been really happy with the results. The last layout I worked on I was using some RS 5-core 22swg 60/40 lead solder and Fluxite paste; both of these date from the 1980's when I used to build computers. I have a Duratool variable temperature soldering station with various bits. My main problems always seem to centre around the temperature which is either too high and melts the plastic in DB-25 multi-pin connectors or not high enough so I tend to leave iron on the work too long. I'd like to address these issues with a l
  9. Thanks for all that, I'll look at the ESU servo pilots although I have used Arduino before for signals. The DCC Concepts guys were absolutely adamant that twisting the bus wires would solve the Cobalt lost addresses problems - it's on their forum. But I'd never seen it anywhere else hence my raising it here
  10. There was a long discussion on the Cobalt forum about the point motors losing their dcc addressing as a result of spurious signals and the twisting of the power bus was recommended plus having other wires cross the power bus at 90 degrees. Hence my questions above.
  11. I was told the twisting helped eliminate spurious signals, nothing to do with shorting. I was concerned that if the bus wires are twisted, soldering droppers could get difficult. And I have looked at the MERG boards and I do like the idea of an 'analog' panel controlling dcc signals and points.
  12. I'm planning a layout 4mm scale about 16 feet long, 2 feet wide, single branch line into a terminus and goods yard, fiddle yard at the other end. It has 8 turnouts and a couple of signals for which I am thinking servos/Arduino or Cobalt for the turnouts. 1) Do I need both a power bus and accessory bus, or will one bus do? 2) I have read the bus wires should be twisted or separated by a wide margin - if twisted how tight and if separate how far apart? Does this apply to both busses (if I have two)? 3) If the bus wires are twisted, how best to attach droppers? 4) I
  13. Thanks for that piece of insight - I'll source a transformer and a DC controller. Easy enough to switch between systems with a DPDT switch. Cheers
  14. The NCE Power Cab starter system, it seems to claim it can control DC-only locos. Is this true? I need to test both DC & DCC fitted locos on my test track and it would save me buying and wiring a separate DC controller/transformer. Thank in advance David
  15. Hi again, starting to get settled here and now looking to at least socialize with fellow enthusiasts. Colin, if you are about text me or call on 0761265011 David
  16. I will miss this one, we don't arrive in France until Wednesday and then it's all hands to the pumps with bank appoinments, notaires, CPAM etc. I will be in touch later though Thanks David
  17. Thank you all for the input, most useful. Although where I'll find time for modelling with a house to do up I don't know ;-)
  18. Thank you Colin, and good to know the line is being restored. We'll be there in September I think, maybe a meet up? David
  19. Thanks everyone for the input - research begins
  20. I'm about to move to France, Chabanais 16150, and being an active modeller I'm looking for any clubs etc within a reasonable distance. Limoges and Angouleme are about equidistant at 1 hour driving and that would be fine. Any help or pointers would be much appreciated Thanks David
  21. Thank you Nigel, that is all very helpful
  22. Good idea but that doesn't fit the operational model - unless it was an Auto-train
  23. DCC is not an option with this layout, it's wired with a 4-CAB DC system. How small? Joueff P10 tank loco is one of the bigger ones ! Believe me I have looked at adding chips and/or capacitors; about the only way would be with a permanently attached coach or wagon and that is not operationally an option. Trackside detectors and a control circuit is probably the way to go and something I will need to look into in detail. I'm familiar with Arduino programming as I use them for the semaphore signals and for point control on another layout. Integrating this into the existing controls f
