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 live steam model locomotives. The blog contains the description of a model Würrtembergische T3 on 7¼" gauge (built between 2006 and 2017), the wagons for this loco (built between 2018 and 2022)  and a 5" gauge model of a Great Eastern Railway Y14 class loco (started in 2020)

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.

Klappdeckelwagen (lidded wagon) (6)

Details on the lids, the steps, handrails, and bearing blocks are the parts that were made during the last month. Most of these parts are directly made from the works drawings of the wagon. These drawings show the parts with dimensions and with almost all the details. This makes making the Solidworks drawing also a lot easier. 




The first things to make were the angle profiles on the lower top of the lids. I had no small profiles at hand, so they are built up from two strips of 1 mm sheet metal. 


With the CNC mill, this small die was made, for forming the ends of a profile. 

In the vice of the shaper, the 1 mm strips are formed.


A second strip is soft soldered to the bent strip

The surplus is cut and filed away...

Scribing the curve...

....to make the corners of the profile.


I don't know if these top profiles are used to stiffen the lids, or if they are designed to give support to the feet of the people who have to climb on the lids to pull them open. I can imagine that this way operators could walk on the lids, without the risk to slide away and fall off the wagon.  




Hand grips

Hand grips on lids, wagon corners, and doors. 

With a simple homemade bending tool the grips are made of 2 mm steel wire (welding rods)


With this tool is easier to make all the 12 grips of the same size and shape

The ends, by which they will be riveted on the lids, are flattened (squeezed) in the vice, between some hardened blocks

The hand grips used to open the lids are ready for drilling and riveting.

Profiles (footrests?) and hand grips riveted on the lids

With the Gressel profile bender, small shackles are bent.  





The shackles and hooks, that are used to connect the opened lids, if both sides had to be open simultaneous. 

The hooks on the real wagon. 

The same bending tools are used to make the side and door grips. These are made of 2,5 mm wire.




Steps


On one side the wagon has steps, to climb on top of the wagon. They are made of 1 mm steel plate.  

The curved handrails were also bent with the Gressel bender. A bit of trial and error was needed to make two mirrored parts with identical shapes and dimensions.


Most of the details were made. 


Bearing blocks

The bearing blocks (horn blocks) are an exact copy of the ones used on the Omk open wagon and Beer wagon. 

The shaper comes to use for making the back plate of the bearing blocks. 

Milling them to shape

and boring out the 37,5 mm hole. 


The body of the bearing block is turned from 40 mm stock material


The bearing blocks (horn blocks) are almost completed. 

Next are the leave springs and the turning of the wheel castings.
