Model Forum / General / Railroads / January 2010GRP scenery
Has anyone tried using GRP as a scenery base? I want a large hill that can be removed for track cleaning and maintenance (behind the backscene), I was thinking of using GRP on an exmet armature.

A gentleman in California has been pushing what he calls geodesic scenery since the mid 1990s. His web site doesd't just push his products but describes the techniques. You should be able to find equivalent stuff in the UK http://www.bragdonent.com/ >Guy >>Has anyone tried using GRP as a scenery base?

Bit like any other scenery really, but sits on MDF thats on pillars (of wood) instead of directly on baseboard. I have a tunnel like that.

Done grass on it but otherwise its a shelf awaiting more scenicing.

Don't do layups indoors, the styrene vapours are not pleasant and will hang around for a long time. You would need a solid mould underneath, same shape as your mountain and prep it with a release agent to remove your shell. The weight would be about 6 oz./ sq ft.,if you use 1.5 oz. chopped strand mat. You would be better off to get a foam shop to sray you a poly iso urethane " muffin " and carve it to shape, outdoors. |
