RhB steam snow blower Xrot 9213 / R12

[Design-HSB]

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.


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.


The rollable tender on my facility.


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!

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 items


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


Of course, the lid can be opened for greasing.

As always, the quality of your highly precise work is mind-boggling!

In the meantime, I was able to produce the missing clamps.

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.


After the 2 D construction for 3 sides I was able to work the staff from 3 sides.


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.


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.

Helmut, your ability to machine exquisite detail exceeds my ability to praise it highly enough!

[Chuck Doan]

Just incredible fabricating!

I cannot believe this guy. -- Russ

Watching all the ways you solve every modeling challenge is endlessly fascinating!
