RMweb Gold The Fatadder Posted November 20, 2012 RMweb Gold Share Posted November 20, 2012 A quick request for assistance. I am trying to replicate the pipe work between the footplate and the tanks on a 57xx pannier, The aim being a first attempt working with brass tube / brass rod and soldered construction. With the backup being an attempt to model it in Solidworks for 3d printing. The more I look at the model, the more I cant live with the half depth pipe (with the associated misplaced pipe linking to the top feed and the flat pipe going across the footplate) I havent managed to find any detail photos, I need a side on close up view showing the pipework and the bracket to the side of it. Does anyone have anything suitable? Ideally I'd have liked to get to a preserved railway and take some dimensions, however I cant see an opportunity this side of Christmas... Thanks for the help Link to post Share on other sites More sharing options...
Penrhos1920 Posted November 20, 2012 Share Posted November 20, 2012 It's mainly the injectors which are probably available from the likes of Alan Gibson or 247 Developments. Wasn't there an MRJ with lots of good side photos? MRJ 61 & 62 You could also try MRJ 70. Also A Pictorial Record of GWR engines Pt2, p.171 Link to post Share on other sites More sharing options...
RMweb Gold The Fatadder Posted November 20, 2012 Author RMweb Gold Share Posted November 20, 2012 Interesting, shame Gibson dont show photos of their parts (would be interested to see what is included on the Gibson injector so I can work out which bit will match the 57xx Can anyone point me in the right direction? As for magazine photos / Russell, I've had a good look, but as usual with printed photos everything is a lot smaller than a decent digital image!

Coombe Barton Posted November 20, 2012 Share Posted November 20, 2012 From the Dean Forest - any good? And the reason I took this is that I couldn't get a decent image from other sources. I'm looking at the same problem. Link to post Share on other sites More sharing options...
RMweb Gold The Fatadder Posted November 20, 2012 Author RMweb Gold Share Posted November 20, 2012 Interesting, very different to the design on the severn valley's 57xx (in that the right hand pipe goes into a long horizontal pipe rather than a vertical). However it certainly answers my other question in showing the location of the support bracket in relation to the firebox. Link to post Share on other sites More sharing options...
buffalo Posted November 20, 2012 Share Posted November 20, 2012 Fortunately, that's one of the GWR's most standard pieces of pipework. The photo below shows the ones in the Gibson Buffalo kit which I believe to be their standard cast component. Nick Link to post Share on other sites More sharing options...
RMweb Gold The Fatadder Posted November 20, 2012 Author RMweb Gold Share Posted November 20, 2012 Fantastic, Should have guessed that there would be something available. I assume this is part 4M717 GWR tank locomotive injectors (x2) Need to get some wheels ordered after the exams finish, will tag a set of these on the same order! Then its time to get back to working on the model. Link to post Share on other sites More sharing options...
auld_boot Posted November 20, 2012 Share Posted November 20, 2012 Also from Dean Forest, you'll have to model 9681 now. I never noticed the slight cut out in the footplate above the steps until now. To complete the RHS of footplate: Link to post Share on other sites More sharing options...
RMweb Gold The Fatadder Posted November 20, 2012 Author RMweb Gold Share Posted November 20, 2012 Perfect thanks, good view of the sandbox linkage as well! Looking at that cab step shows me another job to do! Link to post Share on other sites More sharing options...
RMweb Premium Blandford1969 Posted November 21, 2012 RMweb Premium Share Posted November 21, 2012 Interesting, very different to the design on the severn valley's 57xx (in that the right hand pipe goes into a long horizontal pipe rather than a vertical). However it certainly answers my other question in showing the location of the support bracket in relation to the firebox. Remember that the SVR has three boilers, one with backhead clacks and two with top feed clacks, hence why there are differences. kind regards Duncan Link to post Share on other sites More sharing options...
RMweb Gold The Stationmaster Posted November 21, 2012 RMweb Gold Share Posted November 21, 2012 Pipework varied and you ideally need pics of the engine you intend to model - if you can find any pics of it of course. Link to post Share on other sites More sharing options...
Coach bogie Posted November 22, 2012 Share Posted November 22, 2012 Pipework varied and you ideally need pics of the engine you intend to model - if you can find any pics of it of course. I agree with Mike. Dated photos are the only way to be sure. The prototype views are all post 1945 condition topfeed fitted locos. If you are modelling a 1930's version the pic of the Gibson arangement is appropriate. Succesive manufacturers of 57xx, including Dapol's latest all have topfeeds yet are available with GREAT WESTERN on the side, a version that never existed. The recent Pannier Papers series unfortunately concentrates on BR images with only a few early views. Cabside handrails, firemans side bunker footsteps and roof handrails are other differences to look out for. Mike Wiltshire Link to post Share on other sites More sharing options...
RMweb Gold The Fatadder Posted November 22, 2012 Author RMweb Gold Share Posted November 22, 2012 Thanks I will have another trawl of the Internet but other than the photo in one of the cheddar books I've yet to find another showing 7723. Other than Russell my loco reference book collection is somewhat lacking Link to post Share on other sites More sharing options...
buffalo Posted November 22, 2012 Share Posted November 22, 2012 Yes, there is variations and I agree about dated photos of the specific loco. However, the general arrangement is remarkably constant from the 1890s onwards. The main variations that I've noticed are: 1. The water input from the tanks. Most early examples have the very direct U shaped feed as seen in my photo of the Gibson part above. This was also common on panniers through to the forties. See, for example, figs 455, 459 and 466 in Russell v2, as well as photos of several other pannier classes. This form often appears to have a valve of some form at the tank exit, operated by a rod that goes back through the cab front. The pipe coming from somewhere further forward as on 9681 and 6752 (fig 452 in Russell, dated 1947) appears to be a late modification that I've only noticed with topfeed versions. However, many topfeed examples do not have it. The valve and rod is not present on this type (though may be somewhere at the other end of the pipe?) 2. The water feed to the boiler (upper rear of the injector) either goes through a couple of sharp bends to the topfeed pipe over the tank, or straight back through the cab front to the backhead clacks (on non-topfeed types). 3. The exhaust/drain. Early examples go straight down through the runningplate. Many of these were changed when saddles were converted to panniers so that the pipe turns outwards over the running plate and then back and down behind the steps. When they were kept, the earlier type were usually extended at some time to exit behind the steps. Many 57XX/8750 have the later form though there are many exceptions where the pipe goes through the running plate (e.g. Russell figs 452, 454, 464/5/6).

RMweb Gold The Fatadder Posted November 22, 2012 Author RMweb Gold Share Posted November 22, 2012 Thanks again, looks like the combination of that photo in 1960 and the late 40s photo in the Cheddar book show the loco with the U shaped pipe as per the Gibson casting. While I am asking questions, which size backhead is going to be needed for it? Always get a bit confused, and the descriptions in the catalogue havent helped (other than making me think that I need a small?) Link to post Share on other sites More sharing options...

London cambrian Posted December 9, 2012 Share Posted December 9, 2012 If your still looking, i did photo surveys of two panniers including all pipework etc for a 5 inch gauge model, so i basically got all the details. i have about 70 odd photos of panniers from all angles i could le you have if you drop me a pm Link to post Share on other sites More sharing options...
