Ron Heggs Posted May 11, 2011 Author Share Posted May 11, 2011 I hoped there was some detail in the background of some of the other shots, but obviously not which is a shame. Perhaps access might be better if/when the works near Potato Wharf have finished; although my work trips to Manchester have now finished. Hi, Richard Not to worry, thank you for your photos which will come in handy, and your interest in my modelling I have had two offers of help so far so not all is lost Cheers Ron Link to comment Share on other sites More sharing options...
RMweb Premium jamie92208 Posted May 11, 2011 RMweb Premium Share Posted May 11, 2011 Hi Ron, I have some original engineering drawings of the bridge over the Lune at Lancaster that the Midland built in 1911. This gives details of platework, rivets and the jack arches that supported the deck with the ballast on. If you think this is of any use I might be able to get them to you. I got them from the , now retired, Lancashire County Council Bridge engineer as the Council have built a road on the top of the railway bridge. You might be able to get similar plans from metrolink who will have got them from BR when they took the structure over. I've used mine to produce the etching artwork that;s on my Lancaster green Ayre thread. Jamie Link to comment Share on other sites More sharing options...

RMweb Premium jamie92208 Posted May 12, 2011 RMweb Premium Share Posted May 12, 2011 I'm certain that when the viaduct was transferred the original construction drawings would have been supplied. The ones that i got had all been microfilmed by the County Council. Jamie Link to comment Share on other sites More sharing options...
richard_t Posted May 13, 2011 Share Posted May 13, 2011 GMCRO have a diagram for the MSJ&AR viaduct (drawing A/MSJA/1/7), but nothing for the others. But like a lot of their stuff that I've seen to do with Manchester Central (and close area), it's not in very good condition. Link to comment Share on other sites More sharing options...
Horsetan Posted May 13, 2011 Share Posted May 13, 2011 ....I will take up your suggestion of contacting Metrolink.... Might also be an idea to show them photos of your work so far. That might make them even more willing to help.... Link to comment Share on other sites More sharing options...
Ron Heggs Posted May 15, 2011 Author Share Posted May 15, 2011 Hi, Jamie, Richard and Horsetan Thanks for your suggestions Have written to GMPTE, and enclosed a few pictures of my models. Will now wait for a response Cheers Ron Link to comment Share on other sites More sharing options...
Ron Heggs Posted May 15, 2011 Author Share Posted May 15, 2011 Will be away for the rest of the week, so will leave you with the some pictures, etc. of the modelling of the first pier XX, which is a single pier located on the south side and at the eastern end of the viaduct - A few photos provided by 65179 View of Piers BB Closer View of Piers BB View of upper part Piers AA to the left View of under bridge detail at Piers AA to the left © Copyright of the above photographs remains with 65179 Revised and updated drawing showing location of Piers - Whilst waiting for the bulk plastic delivery, I have started the build with the first of the piers, the single pier XX This will be used to establish a construction process for all the remaining piers The cutting list - 40mm OD PVC pipe 140mm long 20thou plasticard 127.5mm x 17mm 20thou plasticard 130.3mm x 17mm 20thou plasticard 142mm x 5mm 40thou plasticard 137mm x 6mm 40thou plasticard 55.5mm OD/40.5mm ID annulus First fixing the 20thou plasticard 127.5mm x 17mm strip .. then the 20thou plasticard 130.3mm x 17mm strip .. and the 20thou plasticard 142mm x 5mm strip and the 40thou plasticard 137mm x 6mm strip and finally the 40thou plasticard 55.5mm OD/40.5mm ID annulus The size of the common uPVC waste pipe is spot on at 40mm dia for a 10 foot dia pier, and the 3mm thickness makes it a substantial support and the weight enables a low centre of gravity for the structure To enable better adhesion of the styrene to the PVC, the pipe is treated with MEK (Butonone) to prime the surface by removing the PVC surface skin The first two 20thou strips are used to produce a 40thou lamination (easier to curve). One end is tacked to the pipe, and allowed to go off, and then the strip is brushed with Plastic Weld little by little as it is wound round the pipe, and finally the end held closed against the pipe with the back of the knife blade. To ensure the strip is firmly stuck a light wipe with PW around the top and bottom edges finishes the job The second strip is easier to fix following the same process, but with the joint slightly offset from the first The narrower 40thou strip ends are gentle pre-curved, and fixed using the same procedure as previously, with the joint offset again. When firmly fixed and dry any slight joint peaks which are apparent can be filed smooth The next step is to fill the area below the annulus with moulding clay and produce a concave fillet The modelling clay is similar to plasticene - 500g for £1.50 The grey discolouration is from the moulding tool (an old aluminium scalpel holder) The surface will by cleaned up after the clay has hardened Now for the second level of pier decoration - A 20thou x 7mm wide plasticard strip is fixed 16mm below the top of the pipe/pier then a 40thou plasticard square 51mm x 51mm with a 40.5 mm dia hole is fixed on top of the previous strip View of underside A fillet of modelling clay is moulded into position, and left to harden A template is made to enable the marking-off of the flutes, which pass vertically through each side of this upper level Using a fine saw blade (31 tpi) cutting from the plasticard face, the 3 flutes are produced Cleaning up the edges and faces with a narrow bladed craft knife The flutes on the three other faces will be cut in the same way Final cleaning up will be carried out before painting ... to be continued >>>>> 3 Link to comment Share on other sites More sharing options...
Ron Heggs Posted May 15, 2011 Author Share Posted May 15, 2011 Two more photos showing the completed cut flutes ... and now for the arched fluted flat faced vertical top pieces (sounds worse than it really is) ... to be continued >>>>> 3 Link to comment Share on other sites More sharing options...

RMweb Gold Enterprisingwestern Posted May 16, 2011 RMweb Gold Share Posted May 16, 2011 Just digging a hole in the floor for my jaw to go into! As an aside, I assume you measured the OD of the pipe, as 40mm is the nominal ID of plastic pipe. Link to comment Share on other sites More sharing options...
bob hughes60 Posted May 16, 2011 Share Posted May 16, 2011 I really like the way you break the task down and give very useful stepped explanations The modelling clay you used could solve a problem for me with cornicing on station buildings I will be modelling Is there a trade name to ask for or supplier ?- I am only familiar with with DAS? Looking forward to the next bits! Many thanks Bob Hughes Link to comment Share on other sites More sharing options...
coachmann Posted May 16, 2011 Share Posted May 16, 2011 Your dedication to small detail is amazing. I'm sure I saw similar architecture on the Liverpool & Manchester from the window on an ambulance when I was being brought home the long way around from Liverpool to N.Wales.

Gallows Close Posted May 17, 2011 Share Posted May 17, 2011 Why not share the hole I dug earlier? It's full. My jaw is already in there. Link to comment Share on other sites More sharing options...
ColinW Posted May 17, 2011 Share Posted May 17, 2011 It's full. My jaw is already in there. Wouldn't it be simpler to join all these holes together and make it into a trench Colin Link to comment Share on other sites More sharing options...
Mike J Posted May 17, 2011 Share Posted May 17, 2011 Wouldn't it be simpler to join all these holes together and make it into a trench Colin I haven't got a big bottom jaw, but there was a very loud thud just now. Just need to make another space in the trench. Outstanding! Link to comment Share on other sites More sharing options...

artizen Posted May 18, 2011 Share Posted May 18, 2011 If we all drop our jaws into the same trench - does it become trenchant? Wikipedia - 1. (obsolete) Fitted to trench or cut; gutting; sharp. (figuratively) Keen; biting; vigorously effective and articulate; severe; as, trenchant wit. I particularly like the vigorously effective bit. Of course Ron has keenly articulated the real thing using very small pieces of plastic into a work of art. Link to comment Share on other sites More sharing options...

Shadow Posted May 18, 2011 Share Posted May 18, 2011 Can you all please find you own holes. By the time my jaw has dropped it's already full off someone elses. The problem is with Ron, is that he makes it all sound so simple Dave Link to comment Share on other sites More sharing options...
Ron Heggs Posted May 20, 2011 Author Share Posted May 20, 2011 Hi, All Just back from my walking jaunt to Wet Southern Spain, will commence the modelling tomorrow once my feet have learnt to stop moving through the mud Thanks for all your jaw-dropping comments, very much appreciate the thoughts behind them all , I thought I was slugging through a continuous muddy trench Cheers Link to comment Share on other sites More sharing options...

I'm sure I saw similar architecture on the Liverpool & Manchester from the window on an ambulance when I was being brought home the long way around from Liverpool to N.Wales. Hi, Larry Thanks for your comments There are a number of similarly designed bridge structures still around, The Midland Railway appear to have standardised around 1860-1900, on this particular type of structure The Irlam Deviation Viaduct, 1893 over the Manchester Ship Canal was one which springs to mind. The bridge was a single span of approx 365 metres, and tested using 10 MS&LR locomotives weighing a total of some 750 tons Not all the bridges have been recorded on photographs in accessible archives Cheers Ron Link to comment Share on other sites More sharing options...
