'Recycled' by the RAF :-)
I think you'll find that was the sister ship. Tirpitz.
The Bismark was battered into a floating hulk by the Royal Navy and then scuttled by it's crew.

I'm with Michael. I use 12% phosphoric acid flux (London Road Models, usually) and find no need to pre-clean brass or nickel silver before soldering using multi-core, 179 (silver content soft solder), and 145 degree solders.
However, I have found it necessary to clean white metal parts in order to get low melt (70 degree) solder to flow and wet the surface. In this case, I used LRM 9% phosphoric flux.

Indeed. My layout is based on Delph. Not too flat round there, either.

Michael.
Thanks for explaining and illustrating your method. Even in its raw state, the carved terrain quite transforms the scene on the layout.
Might be spurred on to have a go myself on my, currently, flat earth layout!

Will, looks like a very interesting project you have started. I look forward to following progress.
I'm not sure if you are familiar with, or have access to the Scalefour Society web site, but in the layout section of the Forum, Tony Wilkins is describing his Brimsdown layout construction. It includes flat bottomed track and turnouts in P4, so might contain some useful information?

Keith, being pedantic, if there are gangways the buffers should not be touching of course.
Only if the stock has LNER or Pullman type gangways, having a central buffing block and retracted side buffers. Stock using normal, scissors or suspended type gangways should have the buffers touching, as should stock to loco.

Very neat construction, Mike. As always.

Thanks for the explanation, Mike. Making it, in effect, an 0-6-2 will also give it much better lateral stability than having a swinging truck/radial axleboxes at both ends. Good thinking by Arthur.
Enjoying your build, as always.

Mike,
With, presumably, twin beams over the two coupled axles, how are you providing the third support point with two trucks/radial boxes, one at each end?
Dave.
-
Are you going to introduce any camber to the roads, especially the one over the bridge? If so, I'd be interested to see how you do so.
Great to see the layout progressing again.
Dave.

Looking very neat indeed, John.

The boards are aligned using pattern makers dowels (circular items outboard of the wing nut headed bolts) and held together by separate bolts into captive nuts. In the view of the end board, the bolts have been temporarily screwed into the nuts. Normally, they would pass through plain holes in the end of the next board.

Looking very neat indeed, John.
Yes, remembering to add those bits that become hard to access later, is a key concern. I've been caught out a few times with not planning well enough.
Dave.

And very nice it is, too.
Here are a couple of shots of Peter's goods shed in position on the layout. It's surrounded by the cobbled yard roadway - embossed but not painted in these shots.
Might even get round to finishing the layout, eventually.

Lovely work, as usual, Peter. I'm following progress with the layout - mainly on Western Thunder - and your buildings will certainly enhance to scene.
Dave.

Hi Peter.
I'm not familiar with the prototype, but that does look to be a wonderful, evocative model. Nice to see you're maintaining standards in these weird times. Hope you're all keeping safe and well.
Might try to get some more Delph/Holt buildings done once we can travel again, if you're not too busy.
Dave.
-
Coming along nicely, John, and very neat workmanship.
Going back to the "handlebar" discussion, I checked the frames of 2807, at work today, and can confirm that they, and the various "goal post" brackets all have large, flat(ish), 4 feed oil pots mounted to their inner faces - presumably to lubricate the axles box and horn guides.

There's also white and blue - so i suspect the colours help avoid mixing up axleboxes/wheel sets, in due course. I'm sure John will explain the real purpose.
I'm intrigued by the little "ape-hanger" handlebars sticking up from the top edge of the frames - or, perhaps, stylised reindeer antlers?
Dave.
-
John,
That's the sort of forward planning I admire. Although I do try to do lats of planning, there have been occasions when I've rushed in and then regretted it - like chopping out the horn slots and then wishing I left them in to locate axle centres or, as you have, align the frames for drilling.
I commend your more organised approach.
Dave.

John,
On some recent models, I've tried oiling the paper barrier, as you describe - I use cigarette paper - but found the oil must have wicked into the joint and I just couldn't get the solder to take. As a result, I've reverted to using the paper dry but with the part not being soldered chemically blackened. So far, so good.
Dave.

I'm not sure why but the photos of the weathering on the tubular post make it look like it is badly pitted but, in reality, it is a smooth as the proverbial baby's bottom...
And there's me thinking what a wonderful, realistic effect you'd achieved!
Wonderful looking model.

What suspension arrangements have you got on this tender? The front and middle axle bearing are in slots but both sitting very near the top.
Regarding the coal-space strapping, now you've remarked on it, it will eat away at you, so you'll have to do something - even if it's just cover them with a full coal load!
Looking good, otherwise.
Dave.
-
Neat idea, there, John. It will look far better with the wheels closer to the frames.
I take it the plastic card sand boxes are fixed to the body rather than the chassis?
Dave.

John,
Looks very nice indeed - for a Western engine

Sorry to disappoint you, Blanford1969, but the part drawings I have only show side on view on C.L. and plan views. There are no end views or cross-sections showing the profile of the frame stretchers.
