Nick G Posted September 21, 2019 Share Posted September 21, 2019 Evening all, I want to model a large mound of ballast. Just wondering what I could use as a 'core' to build the mound around, any tips? Thank you. Link to post Share on other sites More sharing options...
grahame Posted September 21, 2019 Share Posted September 21, 2019 Probably anything you have to hand that you can carve or shape like: balsa wood, plasticine, plaster, polystyrene, an old rubber, paper-mache, foam rubber, etc. Some may require sealing. 1 Link to post Share on other sites More sharing options...

Never mind modelling piles. i wish someone would tell me how to get rid of them (Apolpgies for introducing thread drift so early in a new topic but it's a subject very close to my heart at the moment, well actually a certain other part of my anatomy, but we won't go there). Oh dear, too much information!!! 3 Link to post Share on other sites More sharing options...
RMweb Gold Stubby47 Posted September 21, 2019 RMweb Gold Share Posted September 21, 2019 It was suggested to me to use part of an egg box to make a coal pile. 2 Link to post Share on other sites More sharing options...

PatB Posted September 22, 2019 Share Posted September 22, 2019 A tip for making more realistic piles of bulk material is to Google "static angle of repose" which should lead you to tables which will tell you the angle at which particular materials will pile up if left to their own devices. 1 Link to post Share on other sites More sharing options...
RMweb Gold Stubby47 Posted September 27, 2019 RMweb Gold Share Posted September 27, 2019 A better pic of the coal mounds. To be honest, I think the left one is too steep at the bottom and needs more flattening. 1 Link to post Share on other sites More sharing options...
Alcanman Posted September 27, 2019 Share Posted September 27, 2019 I had been thinking of using polystrene packaging material covered with plaster (for the 'core') for an aggregates terminal which will be my next small layout project. However, the egg box idea looks good. I think I'll give it a try. Link to post Share on other sites More sharing options...
RMweb Gold Rowsley17D Posted September 27, 2019 RMweb Gold Share Posted September 27, 2019 I use Das air-drying clay to make small mounds for ash and coal. I didn't take any "before" photos of the coal staithes. 2 Link to post Share on other sites More sharing options...
Alcanman Posted September 27, 2019 Share Posted September 27, 2019 Another great idea and I have some DAS air clay. I think it's time to experiment. Please keep the ideas coming. 1 Link to post Share on other sites More sharing options...
