Re: Conundrum over scale width waggons.
Thanks all. Alan Jones also thinks there would be minimal variation between the timber wagons. Maybe an inch or two. If you have access to the dimensions, Pete, that would be a great help.? I don’t think I have Review 46. Before I discovered the magazine. (or maybe I still thought it full of industrial little diesels and therefore of little interest at the time) |

Paul,
Have you read David Smith's article in Review 46? Drawings by Dave Ashley, curated by Stuart Baker.

The correct answer is probably to sell all the iron wagons. Then draw up artwork for a new etch with scale width and get 30 odd etched.? I don’t actually know the size variability within the wooden waggons. They were certainly built without the use of a micrometer. Anyone in this forum in the Wagontracks gang?? |

Let me drop a brick into the mill pond ...
Why do you model in O14? I think if you can be sure of why you model O14 rather than 0-16.5 you ought to be able to answer your conundrum.
I shall now step briskly away from the splash zone.

I have recently been in discussions to look at having some 3D printed wooden FR slate waggons made. ?I cannot do 3D drawing/printing, so am looking forward to this little project. ?It does throw up a problem though. The ?7mm NGA 2T waggon has been stretched

Re: Conundrum over scale width waggons.
开云体育Thanks Paul, ? I agree that the iron wagons probably wouldn’t work as a 3d print.? I can’t remember the detail of the 7mm NGA etches but I wonder if a 3d printed chassis could be combined with the etched sides.? I think the sides would have to be cut away from the base but it might make construction a bit easier? ? Cheers, Robin ? _._,_._,_ |

Re: Conundrum over scale width waggons.
Hi Robin.? The overwide route is looking to be the preferred option. These will eventually run on the extended Dinas project, so will run in mixed takes of ‘up empties’ as a tail load and a ‘down gravity’. ?I have around a dozen iron 2T built and a few 3T. Plus half a dozen in flat pack form. I would like a couple of dozen in each rake, permanently coupled.? The prints are coming from Alan Jones of Coast Line Models, mostly 16mm stuff with a smattering of 009. I hope he will sell them as kits or scratch aids. No prices discussed yet. I’m not convinced that 3D printed iron wagons would work, but this route seems ideal for the wooden ones.? Cheers |

Re: Conundrum over scale width waggons.
开云体育An interesting conundrum!? I guess what you decide to do will depend on how you intend to use the wagons.? If they are to run with your existing (presumably over-wide) stock then I would extend the width by 3mm and accept the inaccuracy.? Aesthetically I think having the stock match would be preferable to having only a few wagons of accurate width.? However, if these are to be part of a future scheme of accurate stock then I would go with the current design and accept the width discrepancy if you use them with the wider stock. ? No help I afraid! ? I guess if these were ever to be issued as kits then you would almost certainly have to go with the wider compromise as even 014 modellers may prefer the extra width to match the 7mmNGA wagons and simplify the fitting of wheels. ? I would be interested in what you decide to do and the 3d print looks excellent. ? Cheers, Robin ? From: [email protected] [mailto:[email protected]]

Re: Lyn - pickups
开云体育Paul - thanks for the NGRM link, I’ll follow with interest! You mentioned your Slaters Lyn kit was missing the side tank weights. These ?as supplied in the L&B Models original kit weighed 54g each; I know David Nicholson went to some lengths to get the loco’s balance right, so this weight might be a useful guide.For the pickups on my Lyn I super-glued gapped pcb to the inwards sides of the forward and rear crossmembers, with phosphor-bronze wires soldered On 5 Jan 2022, at 10:05, Paul Holmes <heatonwood@...> wrote:

Lyn - pickups
Has anyone worked out a satisfactory arrangement for the electrical pickups on a Slaters “Lyn”? The spidery bar frames and cross-members mean that the usual pcb busbar between the wheels isn’t suitable, but space for anything else is very limited. I’ve managed to fit a rough-and-ready setup on the original David Nicholson kit, but I’m hoping someone has devised a more elegant solution!
