Making terrain

Hello Ladies and Gentlemen, Hobos and Tramps, Bug-eyed mosquitos and bow-legged Ants.

Today we will talk about how to build scenery from the ground up.  This works for all types of scenery: be it a forest or buildings.  I'll go over the different types of materials and what is best.  So lets get to it.


    MDF
Medium-density fiberboard (MDF) is an engineered wood product formed by breaking down hardwood or softwood residuals into wood fibers, combining it with wax and a resin binder, and forming panels by applying high temperature and pressure.  MDF is denser than plywood.
MDF does not have wood grain, making it more uniform than natural woods which makes it relatively easy to cut.  This is probably the best material to use since it is very durable, easy to cut, does not warp when wet (except when saturated), and is relatively inexpensive.  I use a 1/8” thick board for all my terrain bases.  A 3’ X 6’ sheet usually runs about $5.
Pros:  Hardly warps, easy to shape with a razor blade.  Accepts wood/white glue.
Cons:  Power tools to cut (bandsaw, jigsaw; you could cut it with a sharp carpet knife but it takes a long time to cut through.)

Chipwood


Pros:  Hardly warps (if at all).
Cons:  Crumbles and splinters when cut.  Need saw or power tools to cut.  If the edges become wet, they will swell like a sponge.

Plywood

 Plywood is a common building material used in houses to furniture.  It is made from intersecting layers of tin wooden sheets. 
Pros:  Good for baseboards.  More solid than MDF.
Cons:  Expensive.  Need power tools to cut.  Warps if not braced. 

Hardboard

Hardboard is similar to chipboard, only much tougher.  
Pros:  Thinner sheets can be cut with a sharp knife.  Similar to MDF.
Cons:  Warps if not braced.  Edges act like chipboard.  Not as durable.

Softwood

Soft Wood is used more for bracing baseboards to stop them from warping.  Alone, it is not very durable and usually costs more than plywood.

Pros:  Easy to work with.
Cons:  Only useful for bracing baseboards.
Cardboard
Cardboard comes in either corrugated or a single piece.  Some use this as a baseboard, don’t use it this way!  Your scenery will look like crap!  It is not durable as a base, warps easily, and is easily damaged if not protected.  Only use cardboard for building up the base or to represent materials such as corrugated iron.

CD's
CD Bases can be inexpensive or even free.  AOL sends them out for free.  They are very durable and will last a lifetime when used as a base.  The only drawback is their size.  Since they cannot be modified, you are stuck with one size.
Pros:  Easy to procure.  Bonds with most materials.
Cons:  Limited by size.

So there you have.  I personally use 1/8” MDF for all of my terrain.  I’ve only had one piece warp on me and that’s because I left it out in the rain.  Having built terrain for GW stores, I can tell you from experience that MDF and CD bases have the longest play life of all the materials.  Only use plywood if your scenery is bigger than 4’X4’ (yes I have built terrain that big) as you need its strength, just be aware of the weight factor.
Chipboard is similar to plywood but is made out of tiny chips of wood, compressed together in sheets.  The wood is sold in various thicknesses and usually come in full 4’x8’ sheets; almost the same price of plywood.
