Welcome

Live steam model on 7¼" gauge of the Württembergische T3 no 924

Welcome to this blog. It will inform you about the progress of designing and building miniature live steam, coal fired locomotives for passenger hauling. Currently I'm working on a 7¼" gauge, scale 1:8, German T3 steam locomotive.

In 2006 I started this new project. This is a small 0-6-0 branch line locomotive of German (Königlich Württembergischen Staatseisenbahnen) origin with outside cylinders and Walschaerts valve gear. The loco is about 1.10 metre long and will weigh approx. 100 kg.

On the left you'll find the index where you can browse through the different articles and on the right you'll find all the extra's. On the top tabs you'll find a brief description of my other locos.

Starting the boiler fittings


 The handwheel in Solidworks according to the german standard. 


Turning from a solid brass rod the contours of the handwheels. Outer diameter, 22.5 mm.


With several lathe tools the handweel gets its shape. 


The CNC program is for the spokes is loaded and ready for milling with a 3mm end mill.
  

The controller software USB-CNC is running on an old laptop. 


 The progress of the milling cyclus (the cutter wasn't too sharp)


 Before and after the CNC milling operation which took about 20 minutes. 


After finishing with the lathe the first batch of wheels. The square hole is yet to be punched.


A week of CNC.
