iankemp Posted March 7, 2011 Share Posted March 7, 2011 How do you go about making one of the top ones? I am going to have to build something for a bridge i am making to replace a cardboard/wood one that i did when making the first bridge. I have made the base part of it by using the wills girder kit and also wills brick kits. These models you have made (making) look so real (once painted and weathered) This is the bridge i was on about. Hope the pics are ok for you to see what i am wanting.

scanman Posted March 7, 2011 Share Posted March 7, 2011 Close-up showing maintenance walkway (handrailing to be added when finally installed on the layout) Will that not be a sight to see! The layout I mean... In absolute awe Ian Link to post Share on other sites More sharing options...
Horsetan Posted March 7, 2011 Share Posted March 7, 2011 The whole thing is just a genius of a work. It's this kind of modelling on the grand-scale (and especially when it's made to look so easy!) which can both inspire and humiliate. Link to post Share on other sites More sharing options...

RMweb Premium MrSimon Posted March 14, 2011 RMweb Premium Share Posted March 14, 2011 Hi, The completed side looks amazing - one question though: will the curve in the sides result in a curve on the deck? Sorry if its a daft question Simon Link to post Share on other sites More sharing options...

Sorry if its a daft question Simon Hi, Simon Thanks for your comments. Certainly not a daft question, but yes, as the deck is supported on beams running across between the top surfaces of the two lower span beams, it will be curved over its length Ron Link to post Share on other sites More sharing options...
'CHARD Posted March 14, 2011 Share Posted March 14, 2011 I totally agree, after seeing those last two posts, my Flabber is well and truly Gasted... Keep it up. What they said Blown. A-Way! Amazing dedication, patience, determination.... not sure quite what to say about this project. Except that in no way do I possess whatever attributes it takes to commit to that! Incredible.

Ron Heggs Posted March 16, 2011 Author Share Posted March 16, 2011 Cornbrook Viaduct - Bridge #2 - Support Structure A small break from the tedious fixing of lattice work, gave me the opportunity to start the decorative bridge supports Drawing of Decorative Bridge Supports Recent photos of existing bridge support and decorative bracing - the upper pillar decoration with a cross on each face is a recent modification © 65179 Drawing of decorative bracing Construction of bracing - 20thou plastic Part completed The rear face requires to be finished in a similar way A second bracing is required to complete the bracing assembly The build included finishing the detailing of the first cross bracing to the bridge support structure, and making the elliptical pillars 32mm uPVC pipe was found to have too thick a wall thickness to successfully form a suitable elliptical form, so decided to form the pillars from 20thou plasticard The circumference of a 32mm OD pipe is 100.5mm. I cut two pieces of plasticard 100.5mm x 220mm, rolled them carefully and placed them inside a piece of 28mm copper pipe. Placed the pipe in a container full of boiling water for 5 minutes. Removed the pipe, and the plastic roll from the pipe and immersed it in cold water. The resulting plastic roll was carefully butt jointed using the copper pipe as a support. A former was made from 60thou plasticard 36mm x 220mm and 27mm x 220mm cross-spliced to form the short and long diameters of the ellipse,. This was placed inside the plastic tube. The whole assembly was placed in boiling water for 2 minutes to relieve the stresses in the plastic tube, and smooth out the curvature of the elliptical tube The finished elliptical pillars with the detailed cross-bracing assembly The detailed cross-bracing Now to make one more cross-bracing, and assemble the bracings and pillars A couple of pictures of the completed lower section of the Bridge support structure - The support structure with the capitols added The holes in the insides of the capitol were used as a template for the visible crosses and slots, and subsequently used to vent the enclosed plastic capitols The upper part of the capitols will be provided with decorative tongues The bridge spans sit in the slots at the top of the capitols The lower portion of castellated section which will sit on the outer part of the capitols Produced in 20thou plasticard it is just 45mm long and 26mm high This item is sat on my glueing pad - 6mm plate glass - 200mm x 100mm with foam pads to prevent it moving across the cutting sheet Overhead view - showing internal construction Rear view The sloping faces and capping pieces are to be added next, then the rectangular decorative columns with the upper castellated sections will be built to finish the support structure Lower cappings added Sloping cappings added Side view Top cappings fitted Castellations added to lower support structure Close-up of detail One more to build and add, then upwards Still required, the top castellations to complete the build Close-up showing upper bracing Decoration on upper support faces Bridge span temporarily in place. ...... No, the far support structure is not part of the build Another view of the bridge span and support structure Close-up showing the detail of the upper bracing ... and this is one I made earlier , suitably weathered This a recent photo of the actual bridge support and adjacent spans © 65179 The upper castellations are complete and fitted The finishing touch to the support structure is the addition of the decorative ‘tongues’ below the upper and lower castellations These were made from 10thou & 20thou plastic card & strip A template for the decor was printed, and the basic outline cut from 20thou plastic card, and filed to a finished shape A second strip of 20thou plastic card was added, and filed to shape matching the main piece A strip of 20thou x 30thou was glued across the bottom of the second strip, and trimmed to suit A strip of 10thou x 2mm was the glued under the last strip, and trimmed to suit Similar decorative pieces were made, and then fixed into position around the capitols Now, it's back to constructing the remaining span beams ... to be continued >>>>> 17 Link to post Share on other sites More sharing options...
Red Devil Posted March 16, 2011 Share Posted March 16, 2011 Superb, I know the area pretty well and this is just unbelievably good, does make you feel like giving up though! Ron, all I can say is it just blows the socks off nearly everything else on here. Link to post Share on other sites More sharing options...
BernardTPM Posted March 17, 2011 Share Posted March 17, 2011 Less than a year ago I stood under that bridge and looked up at this huge, complex and awe-inspiring structure from ground level. You're capturing it to a 'T'. It's an amazing piece of model work. Link to post Share on other sites More sharing options...
sixoh8sixoh Posted March 17, 2011 Share Posted March 17, 2011 Absolutely brilliant! I've been putting off building similar bridge piers as I hadn't figured out how I could do them. My problem is I'm working off only one or two photos so would struggle to produce templates like yours. But thank you, that's inspiring! Link to post Share on other sites More sharing options...
artizen Posted March 17, 2011 Share Posted March 17, 2011 Really good eh!!! This is the sort of modelling that shows that you just need an observant eye and a steady hand to produce astonishing detail from flat bits of plastic. All in a miniature scale that I would struggle to even see clearly as well. Link to post Share on other sites More sharing options...
bennyboy Posted March 17, 2011 Share Posted March 17, 2011 I don't know what is more impressive, the quality of your work or the speed at which you seem to produce it! Have you kidnapped some of those Chinese ladies that work in the Kader factories and used them to build this for you so quickly? Link to post Share on other sites More sharing options...
