I will go and check my things maybe tomorrow but is it a flat rectangular white metal casting, with a large rectangular hole in the middle? If so I am pretty sure I soldered it to the inside of the tender back. The steps protrude through the etched back of the tender and into the big hole, and can be soldered from the inside. One thing I would say about the DJH Coronation tender is it weighs about as much as I do. So I hope you have a big motor in the loco! Iain

Thanks Brian. No problem, none of those tracks are fixed yet, and they will be cut 6-7 mm short of the edge on the appropriate angle, so that the backscene board will fit neatly. Iain

Down slow is wired and tested. I will complete the same with the down fast and then a celebratory video will be released! I might need to get a few bits of stock back from Shap temporarily to make up a few more trains (delighted as ever to continue and repeat the loan into the future, Graham). Getting somewhere close with the goods yard approaches too: This section (including the bit of the North London line through Primrose Hill station) is laid on some very thin cork sheet. It will be painted in situ, then lifted, pva applied, the track relaid using the paint shadow as a guide, and ash ballast applied. Then the excess ash ballast is vacuumed off. It is leftover thin sleeper C&L from the old layout, so it works well to ballast it that way. I don’t need to be quite so paranoid about the running as I am on the rest of it, mainlines in particular. There, making sure it runs smoothly and reliably before all the scenic work is crucial. The goods yard will be largely a static scenic backdrop, with just a small amount of possible movement at really slow speed of goods stock. The trackwork is simple enough with some B8s on a very shallow curve. The track immediately outside the goods shed is inlaid with setts. I have to sort some wagon turntables (no they won’t be working ones!) and probably I should try to pick Jason T’s brains to see whether I can copy what he did with The Mill. Iain

Yes for sure use the Comet deflectors. The DJH ones are undersized and therefore the handrail pillars are too low on the boiler and smokebox. The handholds are also better on the Comet ones. They are a bit fiddly the first couple of sets you do, but they get easier. I used Gibson pillars. Iain

Ian, Terry, yes I forgot the type 3 and 4 tender cut out differences. Good point. If I build any of the three DJH Coronations I have in the drawer, I will also use Comet deflectors and reposition the boiler handrail because the DJH versions are too small and the handrail too low. It really changes the face of the loco. I understand and applaud both the fun and the challenge of making something into something else, as you can see from my own thread! So best of luck with it Ian and do show us how you get on. Iain

Hi Ian, I admire your willingness to have a go à this, although I also think that altering the Ivatt Coronation to a Stanier version is a quite challenging task, to be honest. The Comet Stanier cab etch is for an 8F cab I think, so the wrong size for a Coronation. The way the DJH cab folds up means that joining different or additional sides even of the correct size isn’t easy. The trailing truck and rear frames are completely different as you know, but I’m not sure how easily you can convert one to the other. You could use a Comet spare etch for the rear frame extensions and a separate Comet LMS Pacific trailing truck, but quite a bit of head scratching may be needed. Not sure what plans you have for the tender but the part-welded tank was used on (I think?) 46253-5 as well as 46256/7. For the latter two, the roller bearing axleboxes on the DJH tender frames are not separate, they are cast in one piece with the frames, so altering them will be a massive job. You could remove them completely and replace with Comet plain axleboxes The DJH cab roof is the wrong size and shape (although I don’t think it’s any more or less wrong for each of the Ivatt and Stanier versions). Anyway, just a ramble through my thoughts. Intrigued to see how you go about this. best wishes, Iain

Hi Ian, I’ve not tried to rechassis a Wrenn or HD tender, but the Comet ones are pretty accurate and go together well. The only thing I would say is that using the correct 4’3” wheels will mean you have to remove some material from the baseplate, and the brake shoes need filing back a fair bit. Now whether the Comet tender might then draw closer attention to the less detailed loco body, I’m not sure. Matching the Comet frames to a Wrenn or HD loco body, I’m not sure about. I am fairly sure they were designed for the Hornby body. But I would suggest to make the adjustments to the frames before you start assembling, or at least before you get very far. Iain

Yes, that is exactly how I read it, Corbs. Iain

Thank you Lez, very kind. I should have added for anyone who didn’t know and wants to, that this is all OO-SF transitioning to 16.5mm on the final 3 timbers to join the C&L plain track at the end of each formation. With thanks to Martin Wynne for explaining so clearly why OO-SF works so well, and for the brilliance of Templot to plan it out. I’m dedicating at least this section of the layout to my friend Gordon Stolliday, who set me on my way with both Templot and trackwork construction, and to whom a huge gathering said an emotional farewell on Wednesday. Rest in peace my friend. Iain

Overall view from the south end Shows the change in pairing better I think. Iain

With the construction of two long crossovers and the scissors off the down fast, we now have the down lines completed: Excuse the mess. You know how these things are. I simplified the track plan at the south end by removing the formation which started with a trailing left hand turnout off the up slow, single slip on the down slow and then joining the up fast. I couldn’t see (a) what movement it served and more importantly (b) how I was ever going to build a single slip to work reliably. I had to get the mainlines to function impeccably (without having Norman Solomon to build them) or I could never have Tony to visit. Part of the reason for going to all this trouble was the effect of long shallow crossing turnouts - C10 to D12 - on a gentle curve. You can hopefully see the change in track pairing from 1-2-1 at the north end to 2-2 at the south. The stock runs through these smoothly and once wired, I hope testing will be as successful on the down as it was on the up. In the yard area I am almost certain to try to use some of the new British Finetrax kits as there are few B7s there. I ran out of slide chairs so I have a few to add as can be seen, but overall I’m pleased with how this turned out - especially the scissors which took some time, just doing it bit by bit and trying to make sure I got it right. Yes my tie bar arrangement is less than perfect, but with such long switch blades there is minimal stress. I tried the C&L ones and almost lost my mind. Iain

I’m fairly sure they are on the chassis spacers, Ian. The cylindrical screw-in spacers have a nut soldered to them and you fix the bogie and trailing truck through the spacer into the soldered nut with a bolt. The instructions say to fix the bolt through the spacer and then screw on a nut from underneath but as per TW I do the opposite. I always use a Comet bogie mounting rather than the swinging arm provided. There are a few photos in this thread somewhere I think. Motor and gearbox for a Coronation - I have used Mashima 1628 and 1626 with Comet GB3. I still have a bit of a stockpile of Mashimas. I don’t know enough to say that this is a better combo than anything else but it works well enough. Iain

A little research trip: now that my son lives a few minutes from Camden this sort of trip becomes a lot more straightforward. I snapped a good number of useful photos, principally of architectural details etc. I won’t flood the thread with all of them, but a couple bear posting I think. This one is of the Dumpton Place wall after the render has been removed, referred to by Peter above. I think it possibly shows that the doorway was once where the Pilates ad is hanging now. I’m not certain but this part of the wall looks as if it was perhaps completely rebuilt rather than patched up or filled in. Anyway, I will try to copy the photo in the post above when I finally get round to it. More currently, there was a discussion about wall mounted derricks a few posts ago and I have searched extensively and in vain for information. Then what do I find on the E wall of the Roundhouse? I am leaning towards assuming that those on the Goods Shed wall were at least similar, and it gives me a plausible way to construct them. Any views welcome. A somewhat more momentous update to follow soon. Iain

I can’t remember Dennis, sorry. I know the large and small air tanks are on each side of the footplate, but I don’t recall adding a battery box to any of my Black Fives Iain

I’m glad it wasn’t just me who thought that! I ended up effectively making new mountings using wire and drilled holes as I would have done had it been a Comet chassis. I can see that might be useful although how the two baseplates could be joined and attached while still enabling pickups to be fitted may be beyond my skills! More likely to be helpful if building 46220- 46225 (or was it only up to 46224 I can’t remember….) which had single brake shoes. The rest had twin shoes. The Hornby shoes are single only, even on the new model I think. I’m not sure whether the Gibson items are suitable, sorry. I would recommend (from a baseline of far lower experience and competence than many contributors on this thread) that fashioning something out of metal and therefore maintaining single medium construction, is preferable. Iain

27mm 6’9” wheels will fit, but then the brake hangers won’t. You will need to make some adjustments perhaps but not necessarily like I did: (Scroll down the attached post) Iain

Yes, Pete is correct. just brushed on John. 1/2” flat brush. Iain

Thanks, Tim. I was wondering whether the original doorway was to the right, aligned with the wider steps and bricked over, and the one in this photo was put in later. Any thoughts welcome. And I feel privileged that you have visited this Camden Shed thread: my admiration for Copenhagen Fields is huge. Iain

Thank you Peter. I only have one view of the gate in Dumpton Place, from this G. Freeman Allen book: I have taken a snap of it here: not sure whether I am allowed to, and will remove it if I ought to. Iain

@Ben Alder I’m somewhat late in reading this thread and replying but I have really enjoyed seeing those builds. It’s not easy to marry all those components together! I did a Caprotti Crosti Standard 5 and I have a 6P7F 2-8-2 proposed by Powell still proceeding glacially towards completion, which could get changed into the planned Riddles Standard 2-8-2 if I have a change of heart. I will share in due course. Probably about 2037 at this rate. Thank you for sharing Iain

Thanks again dggar I think the tank I need to model and the one by the new Euston box on your photo are at least close to identical. I can try to scale off some estimated measurements and fabricate something. The base should be ok. The tank itself should be straightforward enough as a cylinder, and I can add rivets and various fittings. The tapered column on which it stands is a different matter - I’m not sure how to go about this yet. Possibly I might need to ask someone to make a 3D print of it. Iain

Many thanks indeed, Jol. I had found reference to parachute tanks somewhere although I can’t remember where. These are tight crops of some of the better photos I have - just my photos of photos so hardly the best method. They are all from similar angles. Different details on top of the tanks in each photo. A sheet? Tarp? Iain

Yes it’s exactly that one. Thanks. I have that photo anyway, and a couple of others too, but not a huge amount of detail. I have only a little info on other examples so hard to compare at the moment. I don’t know whether it was a standard LMS or LNWR item, or something more individual. I would imagine that they used standard items. I can make some sort of fist of its dimensions at least to help locate the track for the goods yard approaches, but it doesn’t need to be completed until later. Interesting, thanks. I took the railed off arc as being there to keep people away from the swing of the derrick and it’s mechanism. But I could be wrong. Either way I am probably no definitely not modelling the basement! Really this is about a plausible backdrop, but me being me, I tend to build something from the info I have and then on finishing, immediately find a contradictory photo. See about 124 posts on my other thread concerning Black 5s…. Iain

Not an appalling gaffe at all - I’ve made dozens worse than that. Thanks for that one, which I have seen somewhere before but will never tire of it. The rat hole is interesting. Thanks. I have done a bit more on the goods shed, yard and approaches, while waiting for supplies to complete the mainlines, which hopefully explains the bizarre construction sequence. Loosely placed to represent the approaches: Inlaid track for close to the shed. I’ve done this in copper clad with some leftover scraps as it will all be covered over, and ornamental. It works though. I have jibbed out on the scissors with tandem right outside the shed. Life’s too short. Need to get some turntables from PH Designs or similar. Another view of a derrick: showing a bit more wall detailing as well. Still slightly unsure how to build these, although I could bodge something. Near Camden no.2 box seen in the first pic above, I have left a gap as on the OS map from the era between the up fast and the goods yard approach as there is a cylindrical water tower/tank something like this: only not necessarily the same. I do have a couple of blurred photos. My go-to reference books like LMS Engine Sheds vol 1 don’t have a definite drawing. Any wisdom greatly appreciated. I also need a supply of code 60 fb rail for the 3rd/4th rail. Or similar I guess. Haven’t found a source yet, except for very expensive 24” Peco lengths. Given I need maybe 100’ of it. Any ideas? Iain

Oh yes. They certainly will! Iain
