Kit built brass loco H3/A6


Recommended Posts

Hi all, I've built this loco for a client.

Built from a brass etch kit from the Swedish manufacturer SMJ/Dekaler & Etsat.

Its a class H3/A6 built to late forties specs in HO scale (sorry.... no OO... ) :-)

It has a fully compensated driveline and it works very nice indeed.

The loco will get some running in later..... :-)

Not the best pics, but I will take some more before I paint it tomorrow.

It can turn out good I think. :-)

Thanks!

The Swedish locos are a bit more brutish than the British..... :-)

 

As I promised, some better pics:

Just the final cleaning left to do in the pics, but I have already primed it.

I will get back with the progress.

Thanks.

Yes, the motor (and decoder) is placed in the tender.

No lights fitted though, as the type only got a top light in the 50's..... and the small lights at the buffer beams were more of marker lights....

It has inside cylinders - yes? Presuming so, is that valve gear that is being driven by the leading axle?

 

My advice, given that there is a fair degree of tarnish to the brass, is to grit blast the surface before you paint and also use an etch primer - there is a good one here (and thanks ot OzzyO for that clue): http://www.ebay.co.uk/itm/290604433582?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649. You really will find that these two stages of preparation make a world of difference to the durability of the paint finish in any circumstance but especially for tarnished brass.

I used a mix of vinegar, oxal acid (reduced rhubarbs), alcohol and soap before priming it.

That turned the metal almost totally clean!

I then rinsed it in warm water mixed with some baking soda and then dipped it in alcohol to remove the water.....

I use Prymol for priming brass, which I find very adhering.....

The Phoenix primer is what I would prefer, but they don't ship to Sweden.....

What a difference some paint makes......:-)

I have painted it black now, and will paint the details and lining tomorrow.

I use cellulose paints for their extraordinary adherence.

A small update.... :-)

This is how it looked before I started weathering it:

The end result will be somewhere in between those pics, as it is too matte right now....

One drawback with pure black is that all details hides in the shadows.....

 

A couple of pics to show how it stands right now..... :-)

It can look good eventually.. [:D]

What a superb finish; a stunning model all round. And I do like those red wheel rims.

One question, I understand its inside cylindered, so what is the function of the rod driven by the leading axle? Is it part of the valvegear?

 

Many thanks,

Dave.T

Thanks! :-)

Yes, the crank is for the valve gear.

I guess it was easier to add it on the outside, the first locomotives in the class had all gear between the frames, but the later had these on the outside.

Thanks! I have tried to replicate a loco that has been in traffic for a good while but still shows signs of maintenance.....

This is probably how they looked in the late forties in Sweden.

Here is my blog with lots more from my layout:

Very handsome machine, has some visual likeness to the UK's B12 and B16 types. The model really really comes to life with the 'in service' weathering, sure the client will be pleased.

 

Ferreting around to find out about this class turned up this layout review thread. Given up trying to stop my jaw dropping.

Yes, my good friend Rikards layout... :-)

It's spectacular!

I got some problem with the decoder install.... it had to be on top of the motor that is in the tender, and it was to tall to be hidden by a coal load.

Fortunately these locos had sometimes a wooden addition to increase the load capacity.

This worked and now a coal load is hiding the decoder!
