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

Hi Eddie

Thanks for the kind words

I wasn't aware of the tread plate issue, I had tried to find something that matched photo's of other Gresley loco's A1,3,and 4's, if you or anyone else have a picture for a Doncaster tread pattern I'd be most grateful and will update my model, I like the idea of rows of rivets, easy to do too. Safety links? not sure I know what your referring too but very willing to include them on the model, as I said I have a long way to go yet, I also have no vac pipes yet, lots of detail to add to the front bulkhead, still have the locking plates and nuts to fit below the dampers, the list goes on. The tender does indeed have it's well tank and the feeds for the two injectors are taken from there which of course means the water valves are fully working, as is the water gauge. She has fully working vacuum brakes which also includes the vac connection for the train behind, along with it's resevoir tested too over 100psi. Naturally the handbrake is incorporated within the braking system and she has fully functional oil trays fitted into her axleboxes. The water scoop is not included for no other reason than safety, this loco will be capable of pulling more than 20 people and it's not worth the risk of a derailment especially if on a raised track at the time.
I'm probably being a little unfair expecting someone to notice where I'm using modellers licence as you'd have to know 4472 very well, Flying Scotsman didn't have this type of tender during her career , well yes it was similar but not for some of the fine details that I have included. My model represents her during the late 30's when she had a Streamlined high sided tender which means the tender didn't have any beading, I wanted the beading as it matches the cab and looks a lot better, also the side sheets curving in at the front again to match the cab. Other than that the tender is correct, well except now for the tread plate..:)

I should have said I'm building 4470 as she was in December 45, as I mentioned this was a part built model that i acquired and so I have to fit in with the work already done, which included part of the cab, this too has a long way to go for completion.

I'd love to have more info Eddie for which I'm most grateful.. I'll send a PM, probably in the morning now as SWMBO has just pointed out the time to me...lol

cheers

steam test done and very good it was too...next week it's time for a few laps around the +1/2 mile track.. should be fun especially as she ran today for 30 minutes without any problems and was very easy to keep pressure at between 70-80PSI.. all in all a good day:)

Very nice! :)
Are you going to be adding the large deflectors too?

Hi Tom

Thanks....Yes.. I have already made them but left them over length until the nameplates arrive from guiplates... on the prototype the nameplates only just fitted lengthwise to the smoke deflectors , this is why I have left them off and over size until the nameplates arrive, once I have those I'll cut them to size and fit them.

hi mana

there is a link in that post of 4470 steaming https://www.dropbox.com/sc/carjz351a94w78v/HzaTWPCvc_ ... regarding moving it.. yes you need two strong guys to lift it into the car... once at the club track we have a hydraulic lift to unload from car to steaming bay.. btw my other build is 4472 in 5" gauge..( still got about 5-10 years of work to complete).. she is very big.. will make 4470 look very small. also in comparison 4470 is a toy when compared to 4472... she will be built very close to the prototype.. full working vac brakes.. working sandboxes, ash pan etc etc.... built from a design by a guy who worked in Doncaster's drawing office and who was intimate with the class
4470 will allow me some playing time while 4472 is being built which is the reason why I took her on....:)

Thanks for the gen, sounds like 4472 will keep you off the streets for a while.

Re: washout plug dimensions for 4470..now changed to 4470 st

Post by greenglade »

Evening guys

Well 4470 is just about finished so I thought I'd post this picture showing the last parts fitted.. smoke deflectors, name and builders plates plus steam pipe covers. The name plates IMHO are a little large but since this is has been built as a practical club hauler I'm not overly concerned about small details, my 5" gauge model of 4472 will be a different project altogether, she will be highly detailed, nothing left out. Meanwhile 4470 has done a few laps at my club track ( each lap is 2600 feet).. I have a few last maintenance jobs to do before signing her fit for mainline service. When I can I'll get some video to show her in action to finish this thread with.

Hi guys

To conclude this thread here's a short video of 4470 on the track this afternoon... still a few small issues which after today I now know what needs doing for a good steaming loco...nothing more than an hour or two of machining in the workshop and she'll be running like a true thoroughbred...:)

hope you like the video https://www.dropbox.com/sc/wyblphv7wcdxuke/vHIYY8SVjb
