good day all
I did try searching for this info but it's either not there or I'm useless at using search engines... I suspect the latter..
I'm at the closing stages of building a 3 1/2" gauge model of 4470 'Great Northern' and have reached the fitting of the cleading which is now ready for painting except I need to fit the washout plugs before doing so. Can anyone help with actual sizes for these items, I'm assuming that there are two types, round and oval. BTW I'm building 4470 as she was shortly after Thompson rebuilt her in 1945.
Kind regards
Pete

all help is most welcome Mick, it could also help me with the correct positions, if anyone does have the full sizes I'd also like those too please as drawings ( other than works) can be incorrect when scaled down. The more info I have the better, even from other scaled drawings as they help to validate others.
btw here's a photo of work so far, the loco has recently gained it's steam certificate and has now been dismantled to finish.
Regards

Thanks Mike
In regards to the tender it's a freelance design, I bought this model 75% complete as it was being sold for a very low price. I'm currently building a larger model of 4472 but since this will be at least another 5 years in building, probably a lot more, when this loco came up I saw it as an opportunity to have something running while continuing my build of 4472. The tender was already built and yes it's horrible, but it works and will do for now. Later once I've finished 4472 I may build a new tender for 4470 to the same standard and accuracy of my 5" gauge 1:11.33 scale model which is about 95% complete.

I have used modellers license on one detail for this tender.. I wonder if anyone picks it up?
regards...

From what I've researched they are on both with metal hoops that fit over both doors to lock into position, admittedly some types even look as if they are concertinaed and indeed fitted to the cab only but I don't have any proof of this other than some bad quality pictures that i have seen. I have close up photo's of both Gresley corridor and non corridor tenders with their own doors fitted, In fact Mallard has separate tender and loco doors and you can see how they interlock using the handles/hoops.
here's an early non corridor photo, I still have all of the small details to add especially in regards to the scoop operating apparatus , I already have all of the works plates awaiting fitting.

Hi third-rail
Floor does need changing... photo's taken of FS today.. well a few years back showed her with the planks running as I have made them, this is incorrect for the period that I am building, that is as an A1 during the 30's so these do need re-doing, however this is not the 'modellers license that i was referring too...

Yes Mick.. just as I said... note the metal hoops or handles whatever they are called which fit over both doors locking them together, simple but effective.
Pete
edit:.. just re-read what i wrote in the earlier post... sorry Mick I always meant to state that Mallard had separate doors as I am doing on 4472 and not the concertinaed type if they do actually exist.

btw great picture Mick, do you by chance have a close up of the water scoop apparatus, especially the arm that seems to fit into a slot and on some tenders is marked 'in' and 'out', it's the one just in front of the water scoop handle as seen from the angle of your photo.

greenglade,
I've sat and studied the picture of your 5" tender and have really struggled to find your modellers license, but apart from the fact it isn't finished and some details are yet to be added, my only criticism is that you have used Durbar type plate for the footsteps. Doncaster certainly didn't use this material and put in neat rows of small rivets I think or spots of weld to provide grip on footsteps and some areas of the footplate of the locos, notably by the cabside on the A4s. Nor have you made provision for safety links, but that has to come into the category of nit picking! Have you put in the tender well tank and the water pick-up gear? The doors are spot on by the way.
It's very easy to find fault if you look hard enough, but I have to say your workmanship looks to be of a high order and your interpretation of the details of the LNER tender is excellent.
For Great Northern, you say you are building it as first re-built, but you have put on the full depth cab sides. The engine was put into traffic in September 1945 with the cab mounted on the boiler and it had short sides. It proved unpopular with the crews, so when it was returned to works in December for the smoke deflectors to be fitted the cab was altered to the familiar frame mounting, so your model will have to have the blinkers to be right.
If you PM me I can give you an extract from the boiler drawing that will locate the firebox top hand holes and some other information extracted from original works drawings which I cannot post here.
