A very old locomotive

[trammayo]

My favourite bit is the posters and line maps, but I'm easily pleased

Well that makes at least two of us then (I do things like that).

Looks a very sturdy coach too - I hadn't realised just how strong they will be when put together.

But I'm looking forward to more on your loco

'the tolerances involved were so fine that one was barely able to pass a farthing between the piston and the cylinder wall' or something along those lines.
Yes, but I think it was the ever popular James Watt describing Mathew Boulton's "new boring machine that could machine cylinders (these were about 1200mm dia) that did not err by more than the thickness of a worn shilling".
The of course the firm of Boulton and Watt was formed and the industrial age was up on us......

Thanks Mick, it's really is very solid would recommend the. To anyone.

That's probably more like it Trev, just one of those I read ages ago and got stuck in my head and jumbled with the rest of the stuff and fluff up there

Have made progress on some of the parts I have been putting off for a while now, namely the motion linkage. As can be seen on the picture of the prototype the loco requires two beams to transmit the cylinder movement to the wheels. I decided the best method to achieve this was to follow the prototype and make four beams sandwiched together to make two; this however did require the manufacture of four identical parts cut from plasticard. I think i just about pulled it off, or atleast the individual sides match and all the holes are in the right place

The saddle for the beam rest and the supporting arms have both been made from plasticard and 3mm steel axle. The coupling rods for the wheels are made be heating up a piece of photo-display-thing wire and pressing it into the plasticard to make a nice solid join. I have also made the front if the boiler, not quite the full dome of the the original but with a bit more work I hope it will look to that effect.

On a final note, I finished one of the trucks I planned to sit behind this loco and other N.L.L.R stock when I get around to building it, and it has allowed me to get a little glimpse of how it all might look running together when finished. The tender is perhaps a little too narrow but I'm not too worried. I might rebuild it in the future at some point, but for now it will do fine

I really like that Ricky, something really different. Great job.

..... but this is starting to look very good. Could start an entire new stream for model railways? Perhaps a rerun of the Rainhill Trials?

A very old topic now too...

So a little over two years after I started, I have finally finished this project of mine, pretty pleased with my first planned, and thought out attempt at scratch building. still much to learn and I suppose I could always get a bit quicker too.

So here it is, the Narborough and Littlethorpe Light Railway`s number 1, Henry Davis Pochin, named after one the brothers that co-founded the large (real) granite quarry my fictional line serves.

It does run but unfortunately had to ditch four wheel drive due to issues with the bolts tightening on the connecting rods and jamming up the gearing. Will probably be more of a shelf queen, especially seeing as I currently don`t have a railway to run on but seems capable with the two wagons I have built so far.

 

[trammayo]

It's great to see it finished - nice work. As regards bolts tightening, have you sleeved them? It acts as a bush/bearing and can give the clearance needed to prevent jamming. I hope you post further on your modelling it looks very good and well finished off.

Neat Model

I like small funky engines like this but find the drives almost impossible to use due to their small model size and the lack of adequate available drives, so instead I built two "pusher" cars that conceal a drive brick under their freight car shells, now I can model small engines without the burden of figuring out how to fix a motor/gearbox inside it. Its an option.

 

[spoz]

Very nice indeed; and I wouldn't have thought that the prototype of such an engine would pull a particularly large train.

 

[musket the dog]

Thanks for the replies. I did consider possibly relocating the drive to the tender if I could find a unit small enough. Like the idea of a pushed car but I feel I would need a more reliable method of coupling the loco and the wagons, just using a buffer and chain at the moment.

 

[musket the dog]

Thought I'd put this in here too. Took a lot of fettleing but eventually got the motion to a point where I would trust it to run without pulling itself to pieces. Have a few more of the tubs built up too.

Got a lot of confidence through this build. Planning my next now, a Manning Wardle inspired 2-4-2.

 

[casey jones snr]

Very nice indeed.

Brilliant effort, well done, like to see more early engines.
