I am intrigued how you painted the discs which appear to be white on the reverse too. Are they detachable?

I painted the backs too! Very much hard soldered - it's the only robust way to keep them on.

Cheers,
Alan

Zs now painted.



These are looking really good, apart from those ugly coupling hooks. It may be that your customer wants these but did you look into whether NEM pockets would work on those chassis?

Cheers

There's minimal space. It's also in the worst possible location - near a securing bolt, and in the area where the keeper plate separates, which I would want retained for future ease of maintenance. While folks love the NEM pocket, it's actually pretty inelegant, and way larger than it probably needs to be in some interpretations of its implementation.

Plus, my experience of coupling pockets glued on is that they always end up falling off eventually.

These could be substituted for a fixed rapido, though whether this looks any better is debatable.

Cheers,
Alan

I reckon those couplings, once blackened, will look OK - better than the chunky Rapidos at any rate! And the locos look tremendous!

Meanwhile, on the North Eastern, 62746 has emerged from the lining shop.

Clearly the official photographer missed it, meaning only this shot was taken.



Up in bonnie Scotland (that being the one before NS was perpetually rabbiting), the Caly tank has rolled back into the workshops to progress its build. The front chassis mounting point has been formed up to allow the loco to sit correctly. The tank fillers and safety valves have been added and the cab backhead fitted to conceal the rear of the motor - and the bent safety valve in the pic has been now straightened!





This loco has been a difficult build - my soldering iron is stretched for this kind of high temperature work, and realistically I need a better one to do large brass areas. Given the starting point, I was always aware this one will be anything but perfect, but hopefully ok, and if nothing else the weight should help that M7 chassis behave.

Cheers,
Alan

I managed to fracture one on one of my Zs. I replaced it with a wire one a la the one suggested for the NGS Shark Brake kit. Once painted it is hardly noticeable.

Zs have all now gained their identities.









Just some minor touchups now and a clean up before they get final varnish coat.

Cheers,
Alan

Lovely work as usual Al, but what about the safety valves?

Removed for painting, will be refitted at the end.

On the NE, the D49 is near complete. The top of the boiler needs another dust of satin varnish, and coal needs added, but otherwise it's all there. Going first for mechanical testing.







Cheers,
Alan

That's a very good-looking engine, Alan.

The nameplates are especially nice.

Best wishes.

Fox Transfers etched plates - they are lovely and highly recommended.
