The green cutting mat is a give-away - the wheelset is not 12":1' modelling. I suspect some of you will have spotted the allen screw in the centre of the axle which marks these wheels as being Slater's - what a shame that AGH wheels are no longer available.

Can you guess the prototype?

"Easy-peasy..." (not sure)

I wish I could work as well as the Guv'nor says it can be done. Tiffin and Earl Grey anyone?

That's right Guv'nor, 'septin you use the axle to line it all up, then cut it up, after it is pinned and soft soldered. And in my case, no tea, just a pink Gin and a splash of tonic.

Oh yes, the webs were cut out on my Taylor Hobson profile miller.

Life gets back to normal after the festivities... although "Locomodels" did question my use of "normal" in a recent email exchange.

Peter is progressing the JLTRT tank wagon and the kit looks like being another NQLTRT version of reality. We have the air-braked underframe with the extended walkway on both sides of the tank barrel and, as suggested by Richard Carr in an earlier post, this combination of details is very good at avoiding the camera. If we can find a photo of a prototype wagon with the full-length walkway then either the wagon is for bitumen (and hence has extra details at the end of the barrel... not in the kit) or the underframe of the prototype is different to the underframe of the model (V-hangers outside /inside solebars for example). Prototype wagons with an underframe as per the kit (V-hangers inside the solebars) and for class A fluids or lubricating oils (no flame tubes or valves on the end of the tank) all seem to have either a short walkway or a long walkway on only one side of the tank barrel.

One might almost think that the kit as supplied is what a committee could have produced on Friday afternoon just for the fun of using whatever was available from stores!

Any one any ideas as to a prototype for this kit?

regards, Graham

Hi Iploffy,
This is for you, and any other member who might be interested enough.

Rather than the slightly facetious reply I gave earlier, I will give a full description of the way that I build a crank axle. However, rather than take over Grahams thread with my ramblings, I will start one just for this. It will be entitled "The GER crank axle workshop". Catchy little title isn't it. This will have to wait until the weekend however as work continues at the watermill.

See you there.

Whilst probably not what you want to hear, I don't think there is one for the variant you have that will be correct in every detail. Full length walkways seem to be a feature of the earlier wagons (with the exception of the bitumen tanks) and the kit has a later chassis, so at a very minimum the suspension mounts will be different, and most likely other details as well. Incidentally, the kit chassis seems to be of the same prototype as the Bachmann 4mm model.

All I can recommend is looking through Paul Bartlett's site until you find something close and if you don't find anything there, have a look here:

And here we have the conundrum faced by many modellers: Build it the best you can and be pleased with it.
THEN put it on a website and wait for the criticisms.

I have one long walkway TTA, I have to agree with you that I have not been able to find an exact match to the wagon, but there are lots of photos on Paul Bartletts site that I still haven't checked. All my others are short walkways.

Hi Richard,
I have gone through all of Paul Bartlett's photos which are available on line... reading Tourett (revised) there does seem to be a number of SMBP tank series which do not feature in that photo stream, this is a pity as the photos in Tourett suggest that some of those missing SMBP / SUKO numbers could be good for the kit.

Pugsley has provided a new reference source, see post no.#159 above, and there are a couple of possible wagons in that collection. Please do not be fooled by some of the photos which look suitable only to find that the non-ladder end has take-offs for kerosene...:mad: or that the walkway is only on one side of the barrel :confused: . And then the most annoying detail of all - a long walkway, on both sides of the barrel, no plumbing on the non-ladder end of the barrel... and V-hangers which are outside of the solebar and brake gear which bears minimal similarity to the kit :headbang: .

Pretty close to a "Not Like The Real Thing" kit.

regards, Graham

So look for SUKO 67955, Esso 66316 and BPO 60778... :) :cool: :thumbs: .

The plumbing is pretty easy to add, if you wanted to (it's for steam BTW, to help the more viscous products flow).

Realistically, I think BPO60778 is going to be the closest that you're going to find.

There are many different permutations on these 45ton tanks - each of the companies had a noticeably different 'take' on how to arrange the brake rigging see http://paulbartlett.zenfolio.com/essopickeringa as I think the photo looks like the Pickering example - but see the similar collections http://paulbartlett.zenfolio.com/essochasrobertsa http://paulbartlett.zenfolio.com/essopowellduffryna and of course Met Camm had its own.

There are certainly some SMBP Class A examples with full length footboards. Whether the end ladders are straight or curved is another question! Are there decent photos of the model from the right hand end (unlike the one on JLTRL site?

Unfortunately, sales of photos of tank wagons imply there is bugger all interest in them and I have scanned very few of what I have.

I'm building my third (JLTRT TTA) at the moment, its a really nice kit, the only points I would make are as follows :-

The distance between the W irons is very tight for scale 7 you will probably find you need to give the W irons a little push outwards to get the wheels to rotate freely.

With Richard's warning ringing in my ears I set to with the measuring stick whilst Peter went about the onerous task of preparing castings. As supplied the wheels do "bind" and inspection suggested that the problem lay in end loading applied to the pin-points of the journals (we are using Slater's products and the design has pin-points to the axle ends and in the corresponding bearings). I measured the length of the bearing and the depth of the bearing hole in the w/m axlebox cxastings... depth of hole sufficient to take the full length of the bearing. Getting the bearings out of the castings was quite difficult as the bearing appeared to be tight in the hole. Lateral thinking to the fore and I reveresed one of the top-hat bearings - light switched on, the flange of the bearing was binding inside the axlebox casting and thereby preventing the bearing from "going home". A sharp knife blade removed a thou or two from the inside of the axlebox casting and the brass bearing then went home about 1.5mm further than before.

Now the wheels and bearings fit nicely... and the wheels rotate without binding.

regards, Graham
