Bachmann/Hornby Rat Sandwich

Looking at the last pics you posted it looks like you've replaced the radiator  grill and added a bit of 3D. Could you show some pics of this area please.

Here are some photos I took at the time I detailed the Bachmann body, including the large grill.

Added roof details (before I made the hole in the exhaust)

This shows an extra thickness of styrene sheet use to lift the roof vent a little higher (upper left)

The large side grills were removed, an extra lip of black styrene inserted and the diagonal strut fitted. The new mesh is a part of a very finely etched, thin stainless steel sheet I bought many years ago.

The finished result before painting. Here you can also see the extra hinges, which only seem to have been fitted to this side of the 25s in later years

Lamp brackets bent up from scrap etch, drilled for a soldered on wire mounting pin

Buffer beam detailing which, together with the cab interiors, are then fixed to the body

I presume the hinged grilles were fitted when loco's were dual braked as air tanks were added down this side of the power unit so bodyside filters would have to be changed from the outside

It’s time to replace the Bachmann 'Class 24' side grills. Anticipating that I would be doing this job on the Hornby model, I had already had some etched by PPD on a sheet with a whole load of other bits and pieces. After choosing to use the Bachmann middle part I decided to use them anyway to see if they make an improvement. At the moment they look a little bit 'stuck on' but I'm hoping that everything will look more homogenous when the body is painted. We will see ...

First off, a picture showing my method of fixing the grills. I was glueing them with CA so I had to get the positioning right at the first attempt. I achieved that with the help of a strip of masking tape to hold the grill while was lowered onto a puddle of CA.

The hinged side grills have slots filed in them and the hinges are represented by small chunks of 0.5mm square Evergreen strip

Now it's on with making the flush glazing so don't hold your breath waiting for an update.  :lazy:

Are you going to market these?

That's unlikely, unless I get absolutely deluged with requests.

 

Actually, I've just been drawing some revised artwork for the grills because I'm still not quite happy with the shape of them. They are just a little bit too rounded, which is the fault of following a published drawing and not a photo. You'd think I would have learned by now.  :fool:

Lovely bit of modelling Kyle. I like your approach to the side grilles, I was planning to detail a Hornby shell to go on a modified Bachmann chassis but the grilles always put me off. In the end the chassis went under the 25/3 which appears in this month's header photo so the project died.

Once you're happy with them, I'd be interested in 3 sets for 25/1s.

I would see if people do want your etches as they do look quite nice.

From small acorns etc....

 

At this stage I won't make any promises, but if people with a firm interest in having Class 25 small side grill etches would PM me, stating whether with hinge cut-outs or without, I might get back to you in the new year.

 

The ones I have used here are etched from 0,25mm (10 thou.) nickel silver but I also want to try an etch in 0.2mm (8 thou.) NS, which would obviously be thinner but might not have enough relief. I'll keep you posted.

Excellent work, however the hinges are on the left hand of the grills, the bit on the right is a securing strap and locating pin with another pin which goes through it to keep the grill shut.

Al,

 

Thanks for the info. It's always good to get the terminology right!

The grill etches look very nice but you have drawn 17 slats compared to 26 on the real thing. If you are looking to redraw them is there any chance you could try and squeeze a few more in to try and get as close to the right number as possible? I'd be interested in three or four sets if you can have a look into this.

 

And saying as you are obviously keen on 25s have you considered drawing up the cab side windows for an etch? The Hornby body has this as a recess that is too far forward and the wrong size. If you've read Karl Crowther's article on doing a 25/3 in a recent MRJ you'll know what I'm talking about. One of the compromises you make with using the Bachmann cab doors is that they are too wide and make putting in a correctly sized cab side window a bit of a squeeze.

 

Cheers

You know, I'd completely forgotten about the MRJ article! Whether consciously or unconsciously I seem to have done most of the same things as Karl so far. Now that you've pointed out the cab side windows, I suppose I'll have to do something with them too. A window frame etch might well be a good idea.

 

As for the small grills, one is a bit limited by what's possible as a half-etch. PPD is a little bit conservative with their recommendations, which I followed for my very first etch (the results of which you see above). For the next attempt I will push the number of slats up to 21, which is still a compromise to ensure that they etch to a decent depth. It will be more than Bachmann managed despite the fact that Hornby had long ago achieved a much finer grill on their '25.

I too had completely forgotten about the MRJ article. Probably because I thought of the 25/3 as a mid 1960's rarity in the North East but photos now seem to give evidence to Tees and Tyne yards trying and hang on to them when they visited. They probably made a good alternative to the Claytons on the local pick ups? 

So with that in mind and a with a bit of inspiration from this thread I went off and dug this out of its tin. Started some 25 (maybe 30) years ago I suppose it's time I moved it on a bit. The last time it was powered, was probably about 15 years ago and I had to stop that session as I was worried about the health of those who witnessed it running. I kid yee not.

I think it'll need to be a thick etch for the cab side window surround. I think I might have used 0.020" or 0.030" just to get the surround to stand prototypically proud. Pretty amazing that Hornby managed the correct number of slats in the grills in 1977, yet Bachmann & the new kid on the block goofed it years later.

You could put me down for a couple of grill etches. Side windies too. I suppose I could always start it all over again.

Anything has to be better than my Mk 1 attempt.

Ps. Just to prove to Waveydavey I do diesels, a Class 24 yesterday.

Nice work Porcy. I think I've said above that the Hornby side window is slightly too far forward which is very obvious when you paint on a full yellow end. I think the best option with an etch would be to just do the cab side frame and dividing bar and leave the filling of the Hornby trench and window size adjustment to the modeller. 24s and 25/0s had a different cab side window from the later 25s due to the former having a drop window and the latter having slide windows. An etch for both types would be wonderful.

 

I have measured quite a few bits of 25 lately so I'll post a few of my detail photos here to illustrate what I've been babbling on about when I have a little more spare time.

Luckily this is just a restoration project & it will be in green. I thought about moving the window back before putting in the insert. Then I thought nah. Maybe the next one? This pic illustrates the error quite well

Have you got the width of the front connecting doors on a 24?

Thanks for pointing to a useful photo.

 

It's strange how the two front locos are standing at different heights though.  :scratchhead:

 I've always had the impression that was quite common. More so on rolling stock. Dipped rail joints and all sorts of things like that caused differences in ride height. Probably if the locos had been photographed just a couple of feet either side of the position the were in; the effect could have been reversed.

Although it's a kettle, this phot. should illustrate what I mean.

This pic by Robert Peach recently popped up in a fb group and shows a subtly different finish where the yellow meets the side window, not noticed this on any other 24/25 and it is possibly only this window on 25241... The other end looks normal on other contemporaneous photos.

Do an image search for 'Three to the Sea' railtour.

The Railfreight livered 20 rode 2-3 inches higher than the green pair.

I'm sorry but I disagree with what I think you are inferring as the 25 263 is consistently lower suggesting that smaller diameter axles have been fitted, with larger diameter axles probably fitted to aid traction (gearing).

 

I have never been able to figure out what people are going on about the 25's as far as I can see if it walks like a duck, quacks like a duck and looks like a duck, it's a duck.

Erm... it's not a duck, it's a Rat! And there are a myriad of differences between the Rats of classes 25/0, 25/1, 25/2 and 25/3 and at different times in their careers. Though personally, I prefer the earlier Sulzer Type 2 'Yogis' - classes 24/0 and 24/1.
