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.

The frame in RAL 3002


A 2K polyurethane paint is used for the second coat. 
With the aid of measure spoons (borrowed from my wife) it is mixed in 3:1 





I tried to spray  with the Badger airbrush and although this worked for the small corners, it was to small for the bigger parts.  The book "How (not) to paint a locomotive" by Christopher Vine gave the answer and I started using a normal spray gun. 



I bought an 0.8 nozzle for my AirGunsa AZ5 and the paint thinned a bit more than 10%  (almost 25%), it went a lot better. 



Before painting the steam cylinders, the were assembled and fitted with sealant (Loctite 5926, is an automotive sealant which I used before with success for my 5" 14xx class loco)
Make sure you clean very well afterwards with cleaning paper you throw away directly afterwards. Otherwise silicone contamination could occur and this does not mix with the paint job.



The smokebox in the final primer coat. Before applying this coat, all the in between spaces were sealed first with Loctite 542 Hydraulic sealant, before assembly. This is a quick and effective way to prevent rust developing between the contact surfaces.




A cake decorating turntable was used to revolve the parts during the spraying.



The first assembly steps.

Coupling and connecting rods make a nice contrast with the red frame and wheels
