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.

Bier-Kühlwagen, first steps in painting (9)

The first steps in painting; nothing to do with painting landscapes or portraits, but painting the wagon. 

The superstructure is mainly made of wood, which has to have a good protection against dirt (oil, steam and coal dust) and moisture and water. I don't think the wagon will be doing well in direct rain (for a model steam locomotive this is less of a problem), but some contact with water can not be prevented.

That is why I used the painting advise and materials that are normally used for painting wooden window frames and doors. An undercoat, and several layers of top coats will be applied.


All parts made; ready for painting.

A undercoat was use for all wooden parts. This is necessary for a good bonding of further coats of paint.
It was applied by brush.

Because most of the construction is only glued together, every corner had to be touched, so that moisture or water is kept away.

Every panel, inside and outside was treated. Two coats were used. 



For all metal parts the Sigma Cover 280 marine primer was used. I also used this for painting the locomotive. 

Even for aluminium this is a suitable primer.

The foldable foot steps; on a piece of wire hanging on the drying line above the heater. 

The first two coats of colour. Bentheimer yellow is used as colour for the outside, the inside is white. 
The wagon will be used as 'toolbox on wheels' and a white inside will hopefully makes is easier to find stuff in the wagon. 

We had, even in February, a few days with nice weather, so I could paint spray outside the workshop. 
(and with face mask, still full Corona proof 😀 )



The roof is on the real wagon covered with roofing felt. To imitate this, I did some experiments with fine sand sprinkled into a wet grey paint coat. I used a roof of one of my gauge 1 wagons. This wasn't really satisfying. 

But I still had lying around an unused sand blasting gun. It came complete with grit  (fine blast furnace slag).


After some practising, this worked fine. With a very low air pressure and some distance to the roof, I was able to get an evenly layer of grit in the wet grey paint.  

This worked fine. 


Because I wanted to simulate the separate bands of roofing felt, it was applied per bands/strips.  

But this didn't worked that well. The difference between the second and first strips was to big. This was due to the fact that the first layer had already dried, and had different colour than the wet paint of the second set of strips. Therefore it was hard to see how much grit should be applied.  
By sanding down the lot afterwards, I could get an more evenly colour, but it still didn't looked OK.  


So a second coat of grey paint was brushed (with a big brush) over the complete roof, and now the complete roof was 'blasted' (sprayed) with the grit. 





By putting the roof upright against the wall, the surplus of grit (that did not set in the wet paint), fell down. This way I could see how evenly the grit layer was.  By moving the spray gun faster or slower, it was possible tho get an live like appearance of the 'roofing felt'.
If this is fully dried, a coat of  transparent varnish will be applied, for extra securing the grit grains. 

The bottom is painted black.

The body, now in the living room for a few days, to get a thorough drying of the paint coats.
After a light sanding down, the final coat can than be applied.   

Painting (or rather drying) is taking a lot of time. 😏



As original, with a grey roof and the coat of arms of Wüttemberg and Hohenzollern on the doors.
These I will order as water slides. 
Other club members have good experience with the Decal store:  https://www.decalwinkel.nl/index.php/geprint-decalpapier-laser.  So I'll give them a try.
