Thanks, and totally agree about the look of it unpainted! Someone said the same thing on another forum too, where I put some pics. It's the black and brass thing, isn't it? I have to paint it though, otherwise it would always look unfinished to me.
I'll take great care not to use too thick a coat anywhere and obscure detail - those walkways on top of the tank, for instance: they'll be a challenge!

Happy New Year everyone - I hope everyone had a good break and plenty of whatever they wanted - turkey, telly, modelling...
My Airfix-Masokits Esso build is almost ready for final assembly now:
I say 'almost' because I'm not happy with the slightly off-centre positioning of the oval' Esso' transfers and I'm going to strip and re-do them, though they can be fixed on last of all, so I'll start of assembling the rest of the wagon.
I found all the transfers for this vehicle a little more problematic than usual: the tiny lettering for the solebars I had to make up from bits and pieces on a 3mm Methfix sheet and cutting and fixing individual letters in that scale and into a solebar recess was a little tricky, though I managed most of it in one go, with only a couple of sections needing re-doing.
The large 'Esso Petroleum' with symbols and running number was less troublesome than expected - as you can see though, I took the easier option of using the complete piece with '3300', rather than cutting off that number and using one of the other numbers provided, which would have made it a little more varied than other models but also involved more alignment issues!
The oval 'Esso' was the most troublesome of all, in term of getting it central on the oval 'shield' shape: I managed to tear one of the pieces, trying to move it round and although I hid the tear fairly well, neither transfer is really central. The transfers are slightly larger than the brass piece, so they need to be really properly central and then trimmed... but without being able to move them around from the front, it's difficult assessing placement from the rear.
I probably should have given the black painted ovals a few coats of Klear first, which might make the transfers easier to manoeuvre, but does anyone have any tips for positioning oval transfers like this?

At long last the Airfix-Masokits Esso tanker is finished:
Delayed by various things as usual, lastly through difficulties with those large oval Esso logos! got tyhere in the end though.
Here's a sequence showing tank fittings appearing on the body:
And here are a few more of the finished wagon:
Lastly, a quick question about spring maintenance: do people usually oil the springs and bearing carriers in sprung wagons? This is my first sprung build and I've always (sparingly) oiled all moving parts, so it seems natural to me, but I wondered whether particular rules apply in 4mm springing techniques...

Thanks Matt!

Thanks Adam; I haven't applied any yet, thought I'd wait and see what other do. I hadn't thought of graphite, interesting idea. What about the type of very light teflon grease sold for model gears, or would that gum it up? Part of the reason I'm considering it is fear of the steel spring pieces rusting over time...

In between build projects, I revisited my modified Triang EM2, firstly to add some small lead pieces to both bogies to help track adhesion:
As you can see in that picture, I had substituted a second metal Triang power bogie (from Ebay) for the plastic one that comes with the original Triang R351 kit, removing the motor armature and connecting both bogies' pickups. The wiring between the two bogies was way to heavy gauge however, and it was slightly inhibiting the bogies from swinging into curves easily, so I changed it for thinner wire (still rated at 1.5A at 12V):
Both bogies also have the Ultrascale EM2 replacement wheelsets:
The bodyshell has SEF flush glazing and a few bits and pieces, such as brake hoses, plus some careful touching in of paintwork:
The bogies connect together using a miniature plug, in the space in the middle of the body, which also necessitated a second upper spring and suitable spring pieces araldited inside the body's upper 'ceiling', mimicing arrangements for the powered bogie. The second upper spring is taped with electrical tape before the roof goes back on, to hold it in place:
Overall, I think it doesn't look too bad, especially for a commercial kit that's probably about 60 years old:
It runs very well, from a slow and even crawl to far above scale speed, and while it has the usual Triang growl it's by no means the noisiest I've heard. I also had the armature rewound by a small trader company that do it as a restoration service and if anyone has one they want rewound, I can look up the invoice and post details on here.
For my next actual build, after the Esso tanker having taking so long, I'm going for something considerably simpler, that'll be finished considerably faster:

Before starting on the Wills platelayers' hut kit, I did a spot of RTR 'detailing', adding lighting to a Roco BLS coach. I do love coach (and other) lighting and I'm always interested in trying different systems, so I was pleased to find an original Roco lighting kit. It uses their (to me) unusual system of metal contact rods, sitting on top of contact springs that connect with the wheels/axles and standing vertically inside the carriage compartment, making contact above with strips running the length of the coach:
The photo above shows the parts, and it also shows some 2mm waisted bearings: this is because I found that the rods weren't making very good contact with the upper strips, so I filed the pips off the rear of a couple of bearings and glued them upside-down into the holes in the plastic lighting rig through which the rods protrude, so that the rod tops sit inside the bearings - here's a pic to illustrate:
I'm not entirely sure I'm fitting the contact strips correctly (I couldn't find anything online to show this - but it works the way I've done it, so I'm happy! Here's how it looks from above with the plastic section sitting in place and the filed-down bearing ready to make solid contact with the brass contact strip:
And here's a shot through the upside-down carriage window, showing how the tops of contact rods sit inside the upturned bearings:
This provided a much more reliable contact - here's a quick test, with the plastic lighting strip perched in place:
I also borrowed a trick from my audio day-job, known as 'ruggedising' (or perhaps 'ruggedizing' if you speak American?) whereby parts that might move in transit are held in place using clear silicone. It peels off quite easily for repair/maintenance but it stops things moving about, in this case the upper contact strips and the bulbs:
It looks messy but it's invisible once the roof's on and it does the job:

Something quick and simple next, a Wills Platelayers' Hut (and by the way, I now know that you can't upload photos on here if they have an apostrophe in the title!), chosen because the Esso tanker too me so long and my other current build (a Sentinel railcar) is taking a long time too, so finishing something quickly will be very satisfying. It's also a chance to try out these magnetic clips from Smart Models:
One slightly puzzling thing straight away though: if you align the ends with the locating ridges inside the sides, the ends are in too far, leaving the sides sticking out:
To have the sides and ends form a neat, square corner, you have to position the ends a little away out from what are surely intended as locating ridges:
If I've missed or misunderstood something here please let me know, otherwise I intend fixing the corners as in the second pair of pictures, to form 'normal' or flush corners (and I've already checked that the roof pieces still fit correctly). I can't understand why they intend there to be the sides sticking out like that... I'll have a google though, in case that's how these its are usually done.
Edited to add: google has a couple of examples where the sides protrude a tiny amount, presumably to represent a side timber laid that way against the end, but nothing like the amount you get if you put the end up against the inner ridge, so not much clearer really!
