Weshty Posted February 10, 2014 Share Posted February 10, 2014 I've finally got around to modelling some limestone "coursed ashlar" abutement and wing wall elements for a proposed girder bridge. The main thing I wanted to achieve is the random aspect of the construction. The real ones take randomness to an art form! I also wanted to try and capture the rustication (the undressed front face of the stonework). Once the clay has dried I will paint and weather them.

scahalane Posted February 10, 2014 Share Posted February 10, 2014 Nice job Des, I've being doing the exact same thing of late, Das modelling clay is the business. Quote Link to comment Share on other sites More sharing options...

BosKonay Posted February 11, 2014 Share Posted February 11, 2014 Looks cracking! Did you scribe it all out? Very neat job! Does the DAS then dry completely rock solid? Quote Link to comment Share on other sites More sharing options...
Weshty Posted February 11, 2014 Author Share Posted February 11, 2014 Thanks Boskonay. General process is: roll the clay to a suitable thickness prod it with a modelling fork to get the rustication effect Lay it on a lined paper template and use some brass sheet to line the horizontal courses The vertical lines are then marked out using some brass cut-off to size Cut in some smaller horizontal lining on some of the bricks Repeat the lining vertically and horizontally until satisfied. As stated already, I intend to redo it to get the more prototypical random ashlar effect. The clay air dries and sets rock hard in 24-48 hours. 'tis great stuff. I propose to provide a kit of resin abutements with wing walls and a brass girder bridge at some stage in the future. Quote Link to comment Share on other sites More sharing options...
Broithe Posted February 11, 2014 Share Posted February 11, 2014 Looks cracking! Let's hope not - not after all that excellent work... Quote Link to comment Share on other sites More sharing options...
BosKonay Posted February 11, 2014 Share Posted February 11, 2014 Very very nice! I wonder how the DAS might work as a track infill for concreted areas, etc? (or cobbles over tracks....) interesting! Quote Link to comment Share on other sites More sharing options...
Weshty Posted February 11, 2014 Author Share Posted February 11, 2014 (edited) A predesigned rubber roller or template would be great. Dieseldo on RMweb has the right idea Or you could do this... http://nevardmedia.blogspot.ie/2012/11/quick-cobbles.html Edited February 11, 2014 by Weshty Quote Link to comment Share on other sites More sharing options...

Weshty Posted February 11, 2014 Author Share Posted February 11, 2014 .. bit of a ledg is Chris From the few pictures I've seen this morning, I completely concur. And I've a few new tips for styrene work. All good, all good. Quote Link to comment Share on other sites More sharing options...
Glenderg Posted February 11, 2014 Share Posted February 11, 2014 (edited) Des, One method I've seen is where you roll the DAS clay out on crumpled up clingfilm or tin foil, and you use a piece of dental floss or fine fishing line to make the horizontal coursing. You could strap several to two pieces of timber to make an "egg slicer" effect if you wanted to speed things up? The vertical joints can be sorted with a blade of some sort, maybe cut down to match the course height? This the sort of look you're going for? R.

scahalane Posted February 11, 2014 Share Posted February 11, 2014 Hi Des, this is the template I made out of 0.3mm plastic. The edges were lined up on both sides to create a seamless tile. The stone coursing was based on the bridge on the Lower Glanmire Rd, Cork. The raised stone was done after with lumps of Das, now I have to get around to painting it proper.

Glenderg Posted February 11, 2014 Share Posted February 11, 2014 Superb stuff Sean, am sure it took a while to do, but worth it no doubt. R Quote Link to comment Share on other sites More sharing options...
scahalane Posted February 11, 2014 Share Posted February 11, 2014 Yip, nearly broke my heart but the Wills card was not quiet the right size so I think it was worth it in the end. Quote Link to comment Share on other sites More sharing options...
