I was curious if you had picked up one of the SLW models.   I think of you every time I see an ad.

Gosh, thankyou! Yes I've had it a few months now, the detail on it is mind boggling, yet it doesn't hold my enthusiasm in the way doing a cheap older loco project does. I can hear the shouts of "each to their own" now!:laugh:

Hi Martyn,

 

That is because you cannot make it your own without detracting from where it started, unlike eBay specials that were tooled up forty odd years ago !

Another one of those "idle moment" thoughts while I was applying filler to the bodyside footholds, having also removed the adjacent small bodyside hatches which the 24 & 25/0 didn't have......

20210726_003509.jpg.56a4f17904e6de76d63cc2b42868461d.jpg

As far as I can tell, from new the 25/0s were not fitted with train heating boilers or associated water tanks, but being based on the 24 body design, still had the cantrail cut-outs for the water tank filler hatches (as seen in the photo). Presumably they had no hatch and were just plated over the opening? They appear to have had the bodyside foot holds, albeit plated over at an early stage. Seems odd!

 

Chance of finding a 25/0 photo clearly showing this? Slim I would say....

Hi Martyn,

 

Having worked in fabrication shops I can tell you that most of the chaps have no idea quite what they are making at times, some don't even seem to be all that interested. The only real concern is that what is made is made to the drawing and fits within any tolerances given.

 

With regard water filler hatches, the chaps in the fab shop would not have any way of knowing if the locomotive would be boiler fitted or not and just build the body shell to the drawing as it was presented to them. Only if there are amendments or deletions would such details be left off a fabrication.

 

These two seem to shew hatches reasonably:

Thanks Gibbo, most useful, we live and learn! Presumably there was still some consideration being given that the locos may yet have boilers fitted, so the plans were followed as you say, yet the no.2 end roof panels are different to those on the boiler fitted locos.

 

Thanks,

Martyn.

I decided against cut 'n shutting the cab fronts and went with plasticard to reduce the window size by about 1.5mm and increase the gangway height by 1mm. 20210727_224950.jpg.aa50ba2842f959e49005c440b5e668a2.jpg

The gangway doors on these locos should be flush with the outer skin of the cab. Realistically the only way to accurately reproduce this would be to sand the centre section flush with the panels either side and scribe fine lines around the gangway edge which I doubt I could achieve neatly enough, so after sanding I will cut out very thin plasticard doors and fit these over the gangway. I need to cement plasticard slightly curved lower cab front extensions in place first though.

 

Cab skirting masters have also been fabricated from plasticard:

20210727_225910.jpg.7ae3dce9dddbcd5bb7c4d54a45e81c5b.jpg

 

Drop in cab-side flush doors need to be tackled next.

Front ends sanded and new gangway doors cut and fitted.

20210728_213339.jpg.401e79a38dfbdf23d31348182ee55009.jpg

The lower cab fairing has been added using black plasticard (barely visible here), this needs further shaping under the doors and sanding yet and the marker lights are yet to be tackled.

 

The roof over (what would be) the boiler area has had the central raised "panel" removed as the 25/0s didn't have them - this, along with lack of water tanks on the underframe, being the main visual difference compared to the boiler fitted 24/1. The former square exhaust panel (with the filled round exhaust) ideally needs paring back in the same way now, a combination of careful scalpel work and sanding.20210728_213204.jpg.f25ab431868ea87cfaa37305896c7ef3.jpg

 

Looking ahead to identity, this was going to become 5152 in blue, but that loco retained some bits of the solebar valencing into 1973, which I didn't particularly want to tackle so 5153 in plain green with full yellow ends is now looking more likely as this was still green in 1973, having moved to Scotland in '72.

 

This is another of those projects where you do an alteration and find 2 more that need doing!

Hi Martyn,

 

Don't forget the rain strip around the water filler.

Sometimes fortune intervenes at the right time! Further to my comment that 5153 was reportedly still green FYE when it went to Scotland in 1972, with the Derby Sulzers site giving a sighting still green FYE in 1973, I chanced upon the 5th photo here:

https://www.rcts.org.uk/features/archive/search.htm?company=&subtype=1&class=25&location=&srch=&page=1

Which clearly shows it in blue at Guide Bridge in June 72, prior to moving to Haymarket. So it looks like blue is back on the table after all.

 

Meanwhile roof work continues:

20210730_142631.jpg.87c05e6dd946dfa3595d863336c1f0fe.jpg

 

New cab side window dividing bars have been fitted and the moulded cab door handrails shaved off...

20210730_142618.jpg.4b6b2a0205d728eb81587861d0a9a704.jpg

 

....to allow a set of flush doors to be fitted (and again, I hope to use these to cast resin ones as they were a pita to make, but they are only 20thou thick so I will have to see how they turn out):

After making the mould, 3 test batches of parts have been made, which turned out better than I hoped given how thin some parts are. The better parts were given a ghosting of grey primer to check for visual flaws:20210803_154814.jpg.839beb31a5fdb2f32df0393e63d19081.jpg

 

This should provide most parts for 2 locos, though the exhaust panel at the top of the image is u/s due to sagging, possibly caused by removal from the mould too soon, or during applying the internal silicon mould that gives it the concave curved profile; it's not worth wasting time filling it for the sake of a tiny amount of resin.

The Shawplan 3 piece roof fan grille was soldered together and fixed into place. Small roof vents above the cabside doors have been added from small leftover pieces of square etched brass mesh simply fixed with Mek Pak and pressed well into place. Small strips of plasticard were then glued inside the sloping cabside window front edges so that the cab front to cab side transition could be sanded to a more rounded profile:

20210807_163727.jpg.dc336b17b031c36b47b277df95af85df.jpg

 

A light blow over with dark grey primer followed to highlight any blemishes, there are a few as usual; 20210807_181034.jpg.79701fe897261007c783066e6dfef354.jpg

 

With Lanarkshire buffers fitted, the chassis had a coat of black applied too.

20210807_181140.jpg.c113dedbc8ed6682f8cbfb5d42acd0b6.jpg

 

And a comparison with a standard Hornby 25; the height difference and other alterations show quite plainly:

20210807_181629.jpg.32c950764d85723ebff689bb7561477a.jpg

 

At this point I'm glad the locos which are to remain as 25/1s & 2s will need a lot less work!

 

Still got the handrails and lamp irons to add of course.

 

A visit to my local car accessory shop today, armed with the RAL code saw some (hopefully!) BR blue paint computer mixed into aerosol form, all very clever. It looks a good match from the bit sprayed into the cap and I'm looking forward to seeing how it turns out on this loco.

Hi Martyn,

 

Its all looking good and the scribe mark for the triangular panel does make the difference. I have found the shade of RAL 5020 to be so close to BR Blue that you will only be able to tell because you were the one that painted the locomotive. You will have to finish with a matt of semi matt varnish though or it will be rather shiny and also with any amount of weathering the shade difference will be even less noticeable.

Hi Gibbo,

Yes I wanted a gloss finish as I intend to use water slide transfers, with a matt varnish applied after. The quick drying time is an added bonus compared to enamels too. Thanks to your info on RAL numbering a while back, it made ordering the right colour much easier! 

 

Cheers, 

Martyn.

Watching with interest on the 5020 RAL, iv got an order lined up for when I get something to painting stage.

Top work as ever Matyn, proper modelling.

All the best

Hi James,

Thankyou, most kind! I hope you are keeping well. The bit of paint sprayed in the cap looks a very, very good match for BR Rail Blue I have to say, so I'm hopeful it will do the trick. To have it available locally and on demand is a real boon!

Yeah not bad thanks Martyn, just suffering from a lack of modelling time, hopefully I'll be getting stuck into a few projects again soon.

 

I'll echo that sentiment on the paint, got a pile of old mk1s I picked up recently ready for a chopping around so I'm thinking I'll try it on them with a RAL grey, iv got a note of it somewhere.

 

Looking forward to seeing the 25s move on and into the paintshops

All the best

Cheers James, hoping to do a bit of 25/2 related work today, hopefully I can get an underframe master made up ready for moulding, or at least started! And hopefully get the 25/0 flaws that have been filled, sanded and touched up with primer.

Autopaints of Huddersfield do bs 381c 114 rail blue acrylic aerosols on eBay. £13 including delivery. Can be had as Matt or gloss.

 

Ps-what is the ral code for coach grey?

Hi Dave,

 

The RAL equivalent for Rail Grey is 7038. I have got a RAL chart and I may post some colours when I have a comparison session.

The 25/0 has had a few flaws touched up with undercoat so should be ready for a trial coat of blue tomorrow.

 

The 25/2 fuel tank / battery box undergubbins master has been knocked up from plasticard and strip (bar the small details) and is being evaluated.20210809_205041.jpg.a1db8aeec2ad9aff136ebda7eb9ff942.jpg

20210809_205312.jpg.a7f22f9e3fdb1cd0969e7f7d6e8de870.jpg

 

This one has the top surface shaped to fit in the hole left in the Hornby chassis when the undergubbins are removed, to aid centring.
