Undulation how to construc

Recommended Posts

On a shelf 1.2m 7ft long by 500mm deep i want to provide some undulations not severe as i will not have enough flat for

helicopters & aircraft.

 

Say 25mm high. How would you construct.  I will have grass over the areas. Represents the Falklands conflict at 1/48 scale

approx 15 pieces in the diormama from Chinook to Landrover.

Many railway modelllers are using building insulation sheets upon which to build  scenery. It's basically expanded polystyrene, denser than that used for packing, extruded into boards of various thicknesses,  10 & 25 mm being common sizes, and readily shaped using houshold tools.

 

A downside is that it is readily attacked by solvent based glues & paints. This can be overcome by coating with PVA glue as a barrier.

 

This is the type of thing  https://www.diy.com/departments/jablite-insulation-board-1200mm-450mm-25mm/26817_BQ.prd

(other DIY shops are available)

 

have a look here to see what can be achieved

OP, try Celotex insulation board (or similar), its denser than expanded polystyrene.

Thanks for your info. Much appreciated.
