Penrhos1920

Is the sound chip located above the wheels? I'm wondering if it will get in the way of EM or P4 wheels? Thanks

Your first photo is of a K15, but it’s one of the last 16 built without Dean bogies, no’s. 231 - 246. The second isn’t a K15 as it doesn’t have a gangway, that makes it a K14.

The outside

Isn’t there a preserved on at the Liverpool museum? As the worlds smallest scale model railway layout which has the whole of the LOR in 10m or so. My phone photo from August this year with Lion / Titfield Thunderbolt in front.

The National Wales museum photo of 118 shows the bar frames much better than most photos and just how much light you can see where traditional British frames would normally be. Have you looked at PTR 21 or other American locos to help make sense of it all? Is this drawing with the original boiler or the Barry boiler? I’m away from home so I can’t tell you the difference. I don’t think it was much. I’m surprised that the GWR bothered to reboiler these locos. The Barry boilers weren’t that old. The real problem with these locos was somewhere in the cylinders and valve gear. In later Barry days above the footplate they were identical to the B1 class. B1s could make it to Trehafod without topping up the tanks yet the Ks couldn’t.

Apart from print size, what do you perceive the advantages of a Shapeways style polyjet over a Mars or Photon?

@Miss Prism I agree. @Mikkel‘s images show just how bad they are. I can’t understand how door and engine compartment windows are so short and don’t line up with the toplights.

I’ve got the ANDR (just across the valley from the Taff Vale) borrowing one as theirs is having a prolonged overhaul.

Yes I’m an active modeller. Extending a P4 layout (Origami Quarry) in my garage with a few friends and lots of wagons for a future EM layout (Penrhos Junction’s) of my own. Penrhos did have 5 baseboards built with some track in P4 before I decided to give up P4 and first change to OO-SF then EM when RTR EM points became available.

I presume they are set by the gauge you have selected for the template. Martin, does templot allow you to specify gauge widening for use in creating the 3D dxf file? Maybe different for different curve radii?

Dont branchlines supply custom rolled roofs? I’m sure a friend bought one.

Do you have any idea when Thomas Ness started in Caerphilly? A quick google has revealed that one of their tank wagons is preserved on the NLR and it was bought by TN in 1939.

Ah but a couple of R2s were converted to composites just before the turn of the century, diagram U14. The conversion probably involved changing the end compartments to 2nd class, later 3rds. U14 running numbers were 52, 60, 199, 208, 209, 217, 625, 626 before 1907. Add 6000 after 1907. The GWR started getting rid of 2nd class around 1908 when it realised that most people who wanted better than 3rd class could afford 1st class.

It has years of usefulness left in it when you put it in your favourite loco as a smoke generator.

It’s all in the compartment sizes. U9 had a pair of 6’6 compartments and a pair of 7’ compartments, give or take a fraction of an inch. The R2 was 1’ longer with four 7’ compartments. R2s can easily be distinguished as the 3 panels between compartments are the same size. http://penrhos.me.uk/Rdiags.shtml#R2 http://penrhos.me.uk/Udiags.shtml#U9 The later R2s had turn-under ends which makes soldering the butt joints even harder!

And the first one

At the moment I keep getting offers of maximum £3 selling fee. This time last year it was only £1 so I sold £2000 of mainly model railway stuff that I didn’t realise I wouldn’t be using. The selling link is still in the same place on my iPad app.

Does anyone know a uk supplier/distributor for InterMountain? I need some of their semi scale wagon wheels. Thanks

Okay I’ve read the whole of this topic and I can’t find the answer. Was there any physical differences between the South Wales and Ravenscraig wagons? After all they were given different diagrams PT003A-C and PT004D-E. Or were the only differences the livery? Has anyone renumbered theirs to a Llanwern set as running in the early 1980s? Or should I hope and wait that A/S will produce them?

I’ve never invested in a tool for folding brass. That is until today when I bought this.It’s actually for working with leather. The jaws are about 35mm wide which is great for folding up the end platforms, especially the awkward two folds in between the extensions down to the well. (See my post of 7th June.)

Next up is a C4 Crocodile C. This wagon is similar to the C11 Crocodile B, the key difference is that the end platforms and bogies are a little longer, much like most of the later crocodiles except the mega K & L designs. The kit design is basically the same and it goes together really quickly. The C4s were built in 2 batches. Numbers 41917 & 41918 and 41929 to 41932. And what a surprise! There were differences. Those I've been able to identify are: buffers, size of the girder to end gussett, different rivet pattern on the top near adjacent to the well. The first couple of photos pickup the build part way through and show how the end platform and side girder are joined together. Note a piece of packing is used under the girder to the left of the clamp. Having completed all for corners the well is slid in place. It is centred by aligning the central groove between the planks (marked with a highlighter so that I didn't loose it!) and the hole in the middle of the girder. It is easier to align one side, put a solder tack underneath and then align the other side. Once the well is in the correct place the girders need to be soldered to the well. The girders have a tendencey to splay out so I put several tacks along the well length, clamping the sides together to ensure that they sit tight to the edges of the floor. The end platform top overlay is in 4 pieces because thats how the GWR built them over 100 years ago. The pieces for 41917/8 are etched in order: When soldered in place there is slight differences along the joints just like the real thing.

The last bit of soldering is for 6 small handrail knobs. These represent the load tie-down points that are on the sides of the wagon. There is one on the side of each end platform and another in the middle of the well. To get the end ones straight I used a long piece of wire to hole them in position before soldering. That more or less completes the C11 wagon. Only the 3d printed buffer housings and axlesboxes need to be glued on.

Whilst you're enjoying the challenges of this kit there's more folding fun. No one makes the correct buffers for this wagon. Several kit manufacturers have made the Churchward coach buffer, and some have even made versions that can be sprung. But this wagon has a shorter version of the Churchward coach buffer. Here I've made a 3d printed buffer housing and etched ram. The Ram is a single piece folded in 4. There is a small hole which needs opening up for a piece of spring wire. The head is a 3 piece laminate which has a rectangular holw for the ram. A bit of extra solder is required on the head to make the correct dome shape.

Now comes the fun bit....making the brackets that the loads are tied down to. This is the starting point. This little piece of brass is folded up first backwards along the vertical centre-line. Then forwards along the two lines that join the little triangles. Then the triangles are filed off to leave this. Then a shackle is taken and folded almost in 2. A pin (0.53mm x 26mm brass lace pin) is threaded through both holes of the shackle and another pin threaded through the resultant hole. Using a pair of smooth faced parallel pliers the shackle is folded tight Both pins are removed and then something a little counter-intuitive is done. The shackle is opened up a little This allows the mounting bracket to be put in place and a pin threaded through the holes. The shackle is re-clamped, the pin cut off and then crimped to stop it falling out. After 20 minutes 3 of the 8 are made. There are 12 load securing brackets in the well and depending upon how the load was held in place not all need shackles fitted..... Relief..
