7mm The Old Man's Workbench - tales of a rivet side

Mr. Finney produces specific kits for specific prototype variants of the 8 wheel tenders. The details are at the end of the 7mm page on his website. In summary...

[1] GNR style with coal rails;
[2] LNER corridor tender 1928 pattern;
[3] LNER streamlined, non-corridor, circa 1935 pattern.

What is not available from Mr. Finney is the 1935 pattern of streamlined, corridor, tender. Gnashing of teeth because that is the type of tender which ran with Merlin for most of that engine's existence. So we have gone with the streamlined, non-corridor, variant which was coupled to Merlin for just six weeks (June to July 1948).

Hmm yes I see now, rearrange, wood trees the for! I'm just now wresting through all the tenders, fitments, types and numbers, there must all ready be a list but its not in the dozen or so books I already have!

Now given that my main modelling interest is GW&GC Jt 1910 plus whatever Peter is doing... with the addition of keeping up with the World of Basilica Fields.... I an cautious about offering advice on matters LNER. As you have kind of asked then I shall offer some thoughts. You could try RCTS Green Bible... plus Yeadon's LNER Locos Appendix Two... or maybe LNER A4 in Detail.

For a thorough and readable explanation of LNER 8 wheel tenders then go to (I think) the Gresley Society web site where there is a multi-part thesis on the subject. With that information to hand, identifying tenders from photos or allocation details in the Yeadon A4 part becomes much easier.

Have you done any work on the resin part of the kit yet?
Yes - I have got the footplate substructure in what I think is the correct place... and added the half-etch top surface. This is another area of the model where I have struggled to convince myself that our assembly is correct - in particular there is no positive location, either left/right or front/back for the footplate sub-structure.

When I get round to completing the cab I may just post some photos and comments on the 3D puzzle of the footplate under the cab. For now, grab yourself a broadside photo of an A4 and then try to decide on a suitable datum line for the footplate and for the cab.... the thing is all curves and gradients apart from the last couple of feet at the rear of the cab, not an easy task to provide supports to achieve a horizontal cab floor.

Graham,

Yes, just found the Gresley society pages, now printing off for a bed time read, should cover everything I need regarding tender numbers and allocations :), it does not seem to cover those tenders with chrome strips at their base, A3 originals or new builds, photos will resolve that.

Book wise.
RCTS 2A, yes
Yeadons, no
LNER A4 in detail, no
Power of the A4s, yes
Profile of the A4s, yes
The book of the A4s, in the post
Photo accompaniments to above vol 1 to 3, yes
Modelling LNER pacifics, in the post
Line side camera ECML Pacifics, yes
Colour of Steam LNER Pacifics, yes
LNER Pacifics in colour, yes
and about 3 dozen BRILL magazines that cover A4s either in detail or as batches of photos, Vol12 #5 Feb 2003 highly recommended.

Is the Yeadon A4 part different from the Locos Appendix Two? or are these the same volume.

The final puzzle is whether the A4 non corridor is the same as the following A2 and A1 in all but minutia.

Yeadon volume for the A4s is a different part of the series to the Appendix Two... the appendix is about tenders, tenders and more tenders.

About the best I can find after a quick scan

Thank you Mick, the photo of '9' shows a shadow under the edge of the roof in just the manner that I would expect.

BTW - look at the vertical handrails... that on the tender is of a different length to that on the engine - the Gresley pages will explain all.

If y'all talking about the cab front sheet then there is no overhang, there is an overhang on the side sheets bit not the front, what I suspect you are seeing is the join between the two, the best I can come up with before scooting out to work is this.

A crop from 60008 at Grantham.

You can also see that the front to side angle has a distinct but small overlap as well, more than the roof in this shot, not something you would achieve with a half etch if the sides were part of the front on the same piece.

I'll see if I can dig out some better shots later

Graham, looking at the construction of the cab from an engineering view point, there may well be locos where the cab roof internal supports are not in the same location, or the fit not as good and the roof front edge may not line up with the cab face exactly, but I'd guess no more than the thickness of the roof material, say 1/8", whether thats an issue in 7mm I wouldn't know, or even visible? I will continue the search as I go through the reference material I have.

Mick, the photos from you and Richard are substantial in helping me decide what to do. Please do not expend any more effort on this matter. Thank you, Graham.

LOL, on the contrary, I need to know this information as well as it will show up in 1:32 and especially in 2.5" gauge and higher.

Looks great Graham, certainly easier than bending up the brass rod that came with the kit.

I can only concur with this comment after fighting the same on my DJH offering - although the equally difficult bit was getting a photo/drawing to work out where they actually went......

Um, you could have asked... there are at least three of us here who have built Finney kits of the LNER 8-wheel tender and hence would have the instructions plus scale drawings. And then there is Andy Beaton who might have been persuaded to offer some official material....
