Nice one Vic, where’s the wormy things? Like the shot on the curve showing the bogies, er I mean trucks, in operation.
Cheers,
Kim
Wow, Vic! What an awesome looking model! Building such beautiful beast is quite an undertaking as well. I especially liked the ‘construction log’. Thanks much for sharing the pictures and I’m really looking fwd to more!
I’m envious.
Nice work Vic.
WOW that thing is sweet
What a cool contraption!
Amazing what people have used for trains[:D]
vic
where is the jet engine??? when do they go into full production ,to sell. [tup][:)]

Now Vic, before you get HJ and TOC all frothing at the mouth; What scale is it in? L-gummi-b, 1:20.5, 1:32, 1:29, or it’s own?
Far better than I could do, I hereby include a tip o the hat!
Bob I built it mostly by eye but nominally used a 1/22.5 scale ruler for overall dimensions, heights etc. 1/22.5 seamed best for my layout, matches existing rolling stock, clearances, etc etc. Besides, the original operated on 3’-6" gauge rail, so 1/22.5 is technicaly correct. even at 1/22.5 its 24" long and very tall, it will be the biggest engine on my layout.
Vic;
From the pictorial essay, looks like you had some serious fun. Well done.
Vic,
That looks more proto on that R1 curve than a lot of LGB stuff we get to look at! And if it’s 1:22.5 it probably is more consistently 1:22.5 than a lot of that L-Gummi-B stuff we get to look at.
Of course this is just a sneaky suspicion I have. [;)][:D][;)][;)]
The obvious question is : “how did I know?”

Yep Ralph you and Fletch both nailed it immediatly…I didnt count on someone decifering the b&w pic on the bench, but afterwords I looked at it and sure enough, I realized I could easily tell it was the most famous pic of the Price.
Yours looks cool, what did you use for drive bricks? and what diameter curve is that? it looks like 3 feet!
It looks like your pivot point for the double bogie is closer to the middle of the double bogie chassis than mine. ( scratch that - I just noticed on your pic that your pivot bolt is in almost the same place as mine[;)]) I tried mounting the bolt in the middle but the overhang front and rear was too much for my layout ,so I used the double bogie chassis’s and a block of wood for the loco chassis mock up to test run around the layout and find the optimal pivot point to minimize overhang by running it at varius pivot points. It didnt take long to find the optimal spot for me. Using the front double bogie as a reference the pivot is about 1 inch behind the lead truck pivot mounting point, this limits the front and rear overhang while the overhang of the center of the car is more or less covered by the width of the car itself. One other advantage is that I could mount the couplers to the the double bogie mounting plate so that the coupler remains more or less centered over the rails through the R1 curves.
this pic kinda shows the coupler mount
You can see the pivot screw bolt here, the left is the front of the double bogie chassis, about 1 inch from the lead bogie mount.
The curve is 2 feet 6 inches radius.
I did not experiment with the pivot positions -but used mathematics!!!
The bogies are IP Engineering 'Budget Chassis" with the Italian SME pump motor fitted to them. The model is capable of a scale 4mph and has a tractive effort of 16N.
I love this locomotive with a passion -it is a real jaw dropper at Open Days watching it corner with all the bogies moving and the chains rising and falling is simply unreal. I remember when I first took it to the ‘O’ gauge Society meeting (it is a 16mm scale model after all…) they were less than delighted to have it on their tracks. However everyone there took at least one photo of it!!!
I hope you enjoy yours as much as I enjoy mine.

Vic, That’s great! very creative
Ron Watson’s can round a 2ft radius curve, 1:20.3 scale 3ft gauge (even through the prototype was 42", so Vic’s is closer to scale!!! Dont anyone ever say 22.5 or 1:24 is the wrong scale!!
Ron’s is powered much like the prototype via universals and gears via long drive shafts off the central gear box, which is then powered above via another shaft from the vertical Marine engine in the cab. in Ron’s case the drive shaft extends through the marine engine into the tender space, where the motor is houses. …basically from where the marine engine is, down to the wheels follows the prototype practice. It looks and works like the original! The only difference is that Ron used worms on axle gears for each wheel, rather than Shay-like Bevell gears. Its very slow moving and very noisy with the large motor and main drive line going nuts, while the drive wheels just slowly turn over…more here:

Fletch - for Ron Watson in Auz!
That is such a cool model!!! mine is a pale imitaion in comparison…[:p]
One of these days I’ll try doing a real driveshaft driven version. Need a small machine mill first!
edit, Never mind, I just re-read Fletchs link about the pivots and linkage, now I get it![:I]
Way Cool…I dig geared engines!!!
Wow, that Yarra Valley loco is stunning!
What I have found interesting looking at the three models on the same page is this: Each modeller has unconsiously taken the model and produced a ‘local version’ of it.
Mine has distinctly English looks to it, Vics has American -it can be said that only the Yarra engine is truest to life as that is Australian. The nearest yet. But to my eyes even that loco has an Australian feel to it.
Curious -when I look at mine I can see that I have automatically styled it in the English manner. I even have an English looking Shay…

Sorry Ralph, I dont agree.
Ron’s is about as close to the prototype as its possible to build, down to the exact details from the info that was available, we obtained some books dedicated to Price too. Even the large stack references the inservice photos of 2 of the 3 built as operated in NZ. The only thing he altered was to name the loco for his own RR…be that as it may…would it surprise you to know Ron maybe isn’t an Auzzie born?
Its hard to talk about British style or otherwise on your model which I consider more an ‘engineering’ or ‘working’ model, rather than a detailed model…but even so, you didn’t try to gear it per prototype, unline some of your other really exellent working models (which I really like a great deal and prefer over this one). Vic’s I agree has some added US features, but is mostly down the line also.
David.
David,
I do intend to return to this model and attempt to get it to work in the original manner. But that is going to require finding a source of the correct (or modifiable) gear parts. It was the fourth of the 13 models that I have made and I am still very happy with it as an early example of Kitchen Sink Engineering ltd.
I am not happy with the Shay…
However the last completed model off the production line, the Hagans -works in the true original manner. However despite the germanic plumbing and sandboxes and oval windows et al… I can still see that it should have an oval plate marked Vulcan Engineering Newton-le-Willows on it -rather than Locomitivfabrik Hagans Erfurt on it!!!
The Klose, currently under construction, although as germanic as I can make it -still looks like something off the drawing boards from Avonside(?)
I do not consider myself to be English -although I spent most of my formative years around English and German built locomotives in the Bulawayo shops before we came to England. But as to style -then David -we have to agree to disagree. But as my father always said “Let us agree on the right to disagree!!![:D]”
Thank you again for the information that you have sent me.
regards
