I mentioned a couple of posts ago that in order to use the GW wheel press to quarter the wheels, I had to remove the Ultrascale crankpin bushes. Whilst they were off the locomotive, I realised that it was a good time to blacken them. That was preferable to try and do it in situ. First of all the pot...

Thanks for all the thoughts on tool boxes. There really does seem to have been a mixture of dates and practices. From the period (i.e. not in preservation and therefore potentially b*ggared about with) photographs that I've been using as reference for this project, I can see the following: RHS, cent...

Morning all, Having just gone over to the show to avoid the morning rush and the queue for bacon rolls, I'd like to thank all organisers and contributors to it. It is absolutely superb. I haven't started on the layout videos yet (not wanting to risk waking the better half who had her first Covid jab...

There are four just on the chip I fitted last night! [1]

[1] The updates of the 48xx blog are running a few days behind real life. <sigh> I have free time to model, or to post, but seemingly not both!

Why the builder put strips of metal, bent at the ends to link the brake blocks I'm not sure when there are perfectly good holes for brass rod to fit. Late last night I dropped my pin vice and snapped the drill bit. There is enough left to use but not safely store. Who sell bits No.s 61-64 and 73-77...

So with the work on the body out of the way for the meantime, and the painting of the chassis done, it was back to the engineering elements, and one of the critical stages, which I always fear I'm going to get wrong - fitting the wheels to the chassis. For this, as always, I use a GW Quartering tool...

I've downloaded that recently. Recommended. Just the right balance of plain language and technical explanation, for me at least.

I forgot to mention that whilst I had the paints out for the chassis, I also painted up the backhead and other cab details provided in the Mainly Trains detailing kit: 48xx backhead painted (1).JPG Whilst they are nicely detailed castings, I was intrigued to find that the layout of the backhead didn...

That really is rather lovely. The finish and lining may have taken time, but it's definitely, definitely worth it.

That's a lovely looking thing...

Are all those rivets half-etched or punched?

Basically yes, but the real anticipated problem was that the falling parts could, directly or indirectly (by damage to ground equipment), cause a derailment or create some other hazard to the safe working of the railway. On the GERS email list, there's a regular posting of any reports by the Rail A...

Ah, they speak a totally different form of french in Paris, full of near incomprehensible (and constantly changing) argot. ..... Good luck understanding the Quebecois then! Oddly enough, when I was in Montreal a couple of years ago, I found the French much easier to understand than during my monthl...

So, now the final run in to putting it all together... First came painting the chassis and the inside motion: IMG_7620.JPG The coupling rods are done in Humbrol metalcote gunmetal, ready for polishing and a little weathering later. See the colour of the prototype, photographed when it was the centre...

Actuality I suspect Pauls' (both G and W) methods as described are very little different from what I (DaveB or Tim) do, leaves proper clearance between rod the nuts so the don't bind and with the nut hard down on the bush as the glue is applies. The point at issue being, do you need the Glue? I jus...

I could say something about outside Walschaerts, perhaps another thread ...

Yes please! I'll have none of that horrible knitting anywhere near any locomotive that I'm building!

Hi all I'm stuck on a project until I can get hold of 4 High Level horn blocks (just the standard ones 1/8inch bearings). Given Chris' entirely understandable situation did anyone else ever stock them? or does anyone have some they could let me buy off them? thanks David I've got plenty of them Dav...

.....and I've mentioned before that if you have to stick your nuts on I reckon there's something wrong. It's in Ricey's chassis book, too. - in theory, I agree with you Dave. - in practice, why take the risk? It's an extra measure of security, is visually unobtrustive nay invisible, and if it stops...

You can deduce the errors in a chassis just by looking carefully at the lie of the coupling rods. With one side rods on front centre look for small differences in the crank angles and repeat on back centre. From the information about whether error is clockwise or counter-clock you can deduce which ...

I use nail varnish to fix gear axles ends in HL boxes. I find a fetching shade of Cherry Red to be the best with Rose Pink a close second................. ;) Easy to pick off if you need to dissassemble. I've mentioned it before, but I use clear nail varnish to secure crankpin nuts. Just the right ...

I always chemically blacken (with an etch marker pen for Ultrascale wheels, Super Blue for steel tyres) the front face of wheels. If the paint subsequently flakes off it's then not very obvious. I must admit, you must have the Magic Formula. I've tried each of these from time to time, and none of t...

So, onto the final preparations before assembling the running chassis begin. There is no fanciness with the wheels - just plain black, and no colour or lining. So I think that it was Jim S-W who pointed me in the direction of the Games Workshop Citadel black primer. Nattily entitled "Chaos Blac...

A few days without any updates, as I've put modelling and the Forum to one side whilst doing a major rearrangement in my study to accommodate the 3D printer. It now all works well, and I'm looking forward to resuming projects. There was one more slightly odd thing about putting the gearbox of the 48...

Croissants in the West Riding?

Things have certainly changed since I lived there... But with the prospect of such wonderful fare on offer, I'll spread the word in a couple of other places.

I mentioned earlier that there were a couple of "gotchas" with the gearbox assembly. Or at least with my construction of it. This is the first of them. It's a rather picture heavy post, as I want to illustrate the snags that I had, and how I got around them. The first one is due entirely t...

Thanks Guy - couple of really useful bits of information there.

I'm still waiting to set mine up. I'm mulling over plans on how to rearrange the study to accommodate all the bits and pieces that I want to have access to, without constantly unboxing and boxing them. Ho hum!

Cheers
