GERMAN Schnellzuglokomotive BR01 steam loco

[rail450]

Hello,

when I found the new steam wheels at tgauge.com I reanimated my dream of the steam loco BR01:

The N model at scale 1:160 was scanned via 3D scanner, downsized to 1:450 and printed

A hellow cylinder with diameter of 4mm was placed within the steam boiler and a servo motor was inserted.

Next steps will follow soon.

Hey cool! A steam wheel project! I am very curious how it goes on. The first images look very promising!

Oh yes, this looks fascinating. Keep an eye on this one. I'm intrigued by that thin motor with the worm screw. Never seen one of those before. Where does that come from?

Hi Rich,
this motor comes from Hobbyking Ultra-Micro Digital Servo HK-5330

I see; it's the motor out of the servo. Is that a motor and gearbox and did it have the worm already on it?

[rail450]

It is a motor without gearbox and the worm was pressed on by me

[Switcher102]

Gosh, a worm that small would come in handy for me. Where did you get it from? Can you get gears that small aswell from the same place? I'd love to be able to get the gears that make up a T gauge motor system separate rather than buy a system and take it apart.

pls, have a look at this side

More than 1 year ago I did some exercises in developing a steam wheel driven chassis:

Now I will do it again with the new steam wheels from Tgauge.com

Thanks very much for the link Siegfried. My browser won't show the photos, don't know why. I'm hoping to see some of this tiny gear stuff at a show shortly here in the UK called the Warley Show.

Very interesting what you are doing. I presume the Shicoh motor and gearbox is too awkward to alter to fit.

I just started the new chassis frame

The new gearing should work like this

To optimise speed reduction the best will be using Z=17 for all gears

To do first prototyping I just ordered this chassis

You are doing a great job on the design of your BR01 steam loco! I like your gear drive using the Z=17 gears. Looking forward to seeing your test results on this set up. Did you purchase all of the gears from the link you provided in an earlier post, and do you have a part number for them?

Joe.

[rail450]

Hi Joe,
I purchased all of the gears from the link I provided in an earlier post.
I do not have partnumbers - select a gear, select the parameters and put it in the shopping basket.

BR,

Siegfried

Awesome work, would love to do the same!
Have you considered the wheel spacing to suit the drive rods in the tgauge shop? I believe its 5.25mm centres.

How do you plan to pick up power? I was considering a permanently wired connection from standard eishindo bogies on the tender.
Love the work, look forward to seeing it progress.

[rail450]

I have to design and to produce my own Valve Gear by chemical etching because the BR01 wheel spacing is about 5,11mm

My plan is to pick up power from the front double bogie and from the rear single bogie or from the tender bogies.

The are some test to do!

BR,
Siegfried

I just received my firt chassis from shapeways as a raw brass printout.

> It fits into the BR01 corpus

> the motor is been held in the correct position

> all drill holes and slots have to bee reworked because they are undersized

Amazing! Fabulous Siegried, fabulous. Looking forward to seeing the finished loco.
