Today I received the new BR01 housing and chassis made of brass.
Both new parts are precision casting products.
The quality is excellent and is very sure the root of a small series.

With his update I show the development history of my BR01 locomotive

At first I milled a gearbox for testing gears and wheels. Followed by
printed brass samples for motor integration, I used printed plastic samples
to optimise space and to integrate cylinder and slider housing.
In the finished brass chassis the digital decoder takes also place.
As perfection a professional did the last and best precision casting chassis.

Here you can see the quality comparison of printed plastic housing and precision casting brass housing.

Notice: the BR01 housing is NOT made of plastic and painted gold, it is made of BRASS ;)

First test of my German BR01 with new steam wheel current collectors.

Slow approach is the big challenge of micromechanics and will be improved again by special contact springs on steam wheel back side

pls, join the test video https://youtu.be/QkSpo0t-ow8

Great work on your locomotive! Love the round house.

Please tell us more about how you are doing your steam wheel current collectors.

Joe.

Looks as if you have a bit of testing to do.....

How are you going to mount the shim onto the metal chassis without it making electrical contact?

Update:

the isolation is very simple by using plastic chassis with glued current collectors

and so I willl run next tests with the new chassis.
