Title: RhB steam snow blower Xrot 9213 / R12
Post by: Design-HSB on September 19, 2017, 01:27:16 PM
Hello together, after I have been working mainly lately with the solution, the automation of my monastery model, it goes also with the Xrot.

It goes on the tender rolls and springs.

(http://www.buntbahn.de/fotos/data/7179/13XrotTender01.jpg)
The brackets for the suspension are brazed. The wheels are turned LGB spoke wheels with the wheels from the action. The soldered rocker, which once again lies on the wheel bearing, already consists of 3 parts and has only 3 mm diameter.

The wheels fit with the low sprockets much better and would be spring loaded otherwise touch the tender ground.

Details of suspension.

In order to make tests it was easy to connect an LGB locomotive. All test journeys were pushed and pulled, also ran smoothly in turnouts.

Holy cow! Stunning work!

The wheels are turned LGB spoke wheels with the wheels from the action.

Nice project!

I might be wrong, but it seems that you have encountered a very common problem when turning the wheels. The surface shows sign of chatter, and If I am right, I might have some suggestions for how to avoid it on future projects.

Thank you Hauk, I think there are only the lights of my workplace lighting. Yes with the good old light bulb, that would not have happened.

Meanwhile, a lot has happened. For the Toy Fair in Nuremberg LGB has announced the Xrot R13 as a ready-made model. After that, we decided to get out of the joint project and build the very similar Xrot R12. The R12 has no driven chassis but must be pushed, it is also green and not brown. We will then get a model, which is not to be confused with the industrial model.

Meanwhile, I have designed the bogies and made almost everything for it. For the sample, I put together a journal bearing, but it still lacks a clamping bracket.

The axle bearing, the hole for the lock has 1mm

Of course, the lid can be opened for greasing.

In the meantime, I was able to produce the missing clamps.
(http://www.design-hsb.de/R12Achslager04w.jpg)
What is still missing is the clamp holding the lid.
For this I have a 15 X 15 mm brass rod stretched on the milling table.

(http://www.design-hsb.de/R12Achslager05w.jpg)
After the 2 D construction for 3 sides I was able to work the staff from 3 sides.

(http://www.design-hsb.de/R12Achslager06w.jpg)
After that, I sawed off 8 mm slices of the rod and reworked, now the clamp is already visible.
So remained of 121.6 gr. Brass, 8 pieces clamping bracket, each with 0.2 gr.

(http://www.design-hsb.de/R12Achslager07w.jpg)
First of all, an M 0.6 thread was cut into the clamping yoke for the clamping screw. Once everything had been assembled for trial, the function of opening the axle box could be checked again.
After cleaning and blackening the axle bearing, ball bearings are used.

Thank you very much for your interest and recognition.

In the meantime, I have used the axle box for a trial in the bogie. The spring is thus compressed under full load. Of course, there are still missing the rockers on the spring pad.

Unfortunately I do not have pictures of the original at the moment, which I can show here for comparison. When I bought eyebolts, I simply ground the collar.

It continues with the bogies.

(http://www.design-hsb.de/R12Drehgestell01.jpg)
There are 2 different bogies and this is the back.
The front bogie is already finished.
Since the sling has a gigantic model weight, the bogies actually have no suspension but end stops. These end stops can be adjusted via the locknuts. Out of these end stops, the wheels can still spring out of the springs due to small compression springs.

Here the counter bearing of the bogie with an axial ball bearing as the model.

Beautiful work! The weathering on the metal looks good. How did you do it?


Title: Re: RhB steam snow blower Xrot 9213 / R12
Post by: Design-HSB on August 02, 2018, 02:26:14 PM
Bill, there's nothing aged yet, I just blasted the brass with alumina and browned.

Post by: Ray Dunakin on August 02, 2018, 05:49:56 PM
That looks amazing! The coloration makes it hard to imagine it's actually brass and not steel.

Some may have already noticed, originally this was supposed to be a RHB Xrot 9213. Only after the announcement of LGB to bring a r13 to the market and the fact that this colourful railway project unfortunately no longer had the original resonance, Wilhelm and I decided to make the R13 a R12 to be able to finish the project at least for us .

The R12 itself is currently in the processing and we are also following this with interest, more on this [url = http://www.dampfschleuder.ch/] here [/url]:

Today I used to deal with the tender, because it is identical to the same and also identical to the tender of the steam locomotive.

So I used yes for the suspension eye bolts:

(http://www.design-hsb.de/R12Achslager08w.jpg)

Much to me the picture of the water level sensor-probe from the tender and I had a solution.

Look here today I have built the water level sensor-valves.

(http://www.design-hsb.de/R12Tender20.jpg)

Such a faucet consists of the following parts.

An M1 eye bolt with waistband.
A 2 mm piece of 1 mm tube for the spout.
An angle of 1 mm brass wire with an M1 thread.
With a M1 nut held, the faucet is even still to be operated.

Only there is no water in the tender, therefore no water can come out.

I think the good looks of my burnished brass hangs with my way of processing together. I radiate the parts immediately before the brown with aluminum oxide, which cleans the brass and raut it quite finely. Through this processing, the blueing works much more intensively.

Looks great, Helmut!
Even though there is no water in the tender, you could pose a very convincing photo by having a worker near one of the valves and temporarily pushing the end of a clear fiberoptic rod lightly into the opening of the faucet and the other end poking into a clear resin puddle on the ground to model a stream of water squirting out.

Hi Bill,

Therefore, I was glad that after soldering, at least 2 of 3 taps still allowed to move.
