  1. Nice work. The oxford jubilee wagons are a good base for an inexpensive wagon which can be knocked into shape relatively easily. The D22 looks good, you can never have too many of those.
  2. Well, the CR ones all had wood jibs. A bit of history. The wood parts of that derrick are mahogany, It is the same timber that forms my front room floor, "recovered" from a building that was being demolished about 25 years ago. I think it would have been laid about 1860, so it's actually very old. Probably started growing a century before that. The main advantage of it is that it just needs a wash of dilute white paint and it really does look like wood.
  3. Thanks, 40 lpi might be ok, I'll get some and play about. The difficulty is that the jib is very light and any drag means that it doesn't drop. Worth a try though.
  4. Well, that is excellent in 2mm, close up pics are harsh. Observations suggest the jib was usually on a chain and the hook on a rope. That must be a very fine chain. I have another crane I have been messing with which does use chain. The problem is that it doesn't scale well in a dynamic situation though like yours it looks good in a static situation. I think to be on scale I need a chain that is about 50 link/inch. hmm.....
  5. Good idea. I had the same issue with electromagnets and much prefer the moving magnet method.
  6. Very nice , great to see some more TLM kits being built. For couplings I use the smiths ones and file them down a bit. I had a go at the big 50 ton one a long time back.
  7. Hmm, I went for ready made d type for all the control stuff and Click 4 pole lighting connectors wired with 1.5 4 core flex for the 2 dc power busses https://www.ebay.com/p/Famous-Original-Male-to-Female-25-Pin-Parallel-Db25-Printer-Cable-2-7m-M5g4/1070134147?iid=252471965711&rt=nc

    Hello

    Very nice scenic work.
  9. I suppose someone could do an etch for the parts, the rest is just stock sections of tube. All those coach bolts on mine are just ordinary pins, drill through the wood and solder them to the brass. I looked at a lot of pics at the time, what struck me was that they were all similar but slightly different. In construction use they were regularly taken down and moved from site to site so if it looks like it would work it is probably right. Jib lengths varied, somewhere I have a pic of one with what must be a 60 foot jib. Back when trees grew that high......
  10. They look very sharp as a set of prints. I will watch the build, my concern would be mass, but I may be proved wrong. Interesting modelling anyway.
  11. Well, the layout is wired to be operated by several people if they are about Mikkel. Long term some sort of operating schedule will help this idea. Getting there slowly.
  12. Well, its a rather rough thing. The gearmotors are I think for model boats, the rest is bits box. It must be about 20 years old, I might have a go at a new one with some of these good gearmotors from china. The hollow pivot shaft of the derrick is the bit of brass just protruding from the black gear.
  13. Right, back to some modelling. I have said painting is not my forte, add full size painting to that too. Anyway, a scotch derrick. I made this a long time ago for the previous layout, but I haven’t got round to fitting it since its a bit vulnerable as it is towards the front of the layout. Scotch derricks are a simple crane, they were used in large numbers throughout the railways and industry in general. Drawings of the size preferred by the CR were published in “The true line “ and mine is scaled closely to those. It’s a basic model, the wood bits are mahogany, the iron bits are brass. The gears are from all sorts of stuff, anything with likely usable bits never gets thrown away without salvaging the gubbins. Well that looks ok to me. But, why not make it all work. Er, a controller ….. A bit of video of it in action. I have rebuilt the top end which had gummed up over the years, the drive system needed tidying up, but I’m fairly happy with that. Somewhere I have some lacing cord to replace that hairy cotton. The ball on the hook is a bit overscale too, but anything smaller lacks the mass to make the hook go down.
  14. Magnets. Really I have a layout held together by magnets. Nudge stuff it moves. Nudge it back, no damage.
  15. Well, if you want enough 7/02 to last a lifetime buy a drum of 8 core alarm cable. less than 20 quid for 100 m drums, as an electrical contractor I get it for half that. I'd also agree with junctionmad . its easy to solder discreetly to the bottom of the rail. spot the droppers ........
  16. Yes but they whistle three times in every sentence Nearholmer. This is due to having learned English by listening the the world service on short wave wirelesses.
  17. Just a thought Ruston, how about a bit of 3 mm acrylic mirror ? Only a few pounds for an A4 sized bit and you can cut it to a curve with a fine blade coping saw .
  18. Hmm, some interesting pics . Now, I am looking at the pic posted by Killian keane. So why would there be an intermediate lamp left on the end of what seems to be a brake coach ? Now, it may be a very localised shunting move that does not pass a signal box, but even so I'm a bit confused. Even if it was something done on the nod in that location why would the crew not have taken it off for a photo? And yes , I must get the damn decorating done and get back to modelling before I get far too pedantic for my own good.....
  19. Well, The SECR crane tank was the basis for this one. I do have my daft moments....
  20. I had a play with the nelevation one at the scottish model railway exhibition a couple of years back. A nice solution if you can afford one. If you do decide to motorise it all give me a shout, I'll blog the circuit diagrams for the one I built.
  21. Ah, fond memories. Those historic series airfix kits were part of my youth. From memory the motorising kit was separate and drove a small wheel with a rubber band for friction onto the main wheel. It was the same motorising kit for the beam engine and the petrol engine. Mine didn't go round very well either........
  22. I knew nothing about the Southlands Wooden Railway and the involvement of so many ex-pat Scots in its construction, but the above pic led me to find out about it. https://the-lothians.blogspot.com/2013/06/the-saga-of-southlands-wooden-railway.html An interesting read, I particularly liked the quote ' " The old loco carried a lot of copper and brass fittings and ornaments, and these were at that time valuable scrap, so along with the cast iron cylinders, they were sold to an Invercargill foundry in exchange for a turnip ridger worth £28." Anyway , an interesting diversion from decorating.
  23. I'd always have a resistor for each LED. The 560 ohm ones will protect the LED from damage, but they will be very bright. I purchased a couple of dozen cheap pwm motor controls. https://www.ebay.co.uk/i/332412126587?chn=ps Built in switch and they are excellent for dimming LEDS and mini incandescent lamps. Thing is you want LEDS to be a bit brighter if you are lighting the layout strongly for a photo , but dimmer for normal viewing. These sort the problem for not much more than the price of a switch on its own.
  24. Runs as requireds post a page back has a railway connection. Andy MacMillan's father worked for the Caledonian railway. I knew Andy and one time I was chatting to him the subject of my interest in railways and particularly the Caledonian came up. Andy went to his extensive bookshelves and dug out a volume and handed it to me, " You can have this then, more use to you than it is to me" . That is how I came by my copy of the CR 1919 rulebook.
