The set that I always thought was interesting are the sink hole maps. As a function of how our hobby works we take our game tables and add terrain on top of it. This works well and we get to have a pretty wide range of terrain types, but what about if the terrain fell away. The idea of moving down into the table seems like a challenge and I'm going to work on bringing the sink hole maps to my table with 3D terrain. Of course, this is primarily for BattleTech, but I'm sure I will be able to use these boards for other games.
To start with I pulled out my collection of map sheets and found the sink hole sheets. As far as I can see the lowest terrain is sublevel 3. So my plan for now is to only go that deep with my design. I however, want to be able to cover a 4' x 6' table so I need to expand the maps a little.
I sketched out some ideas on graph paper and game up with this.
This involves making 6 2' x 2' terrain tiles. The benefit of 2' x 2' tiles is that I will be able to move these around and turn them in different directions and I will be able to make lots of variations. They will also be easier to transport than larger sections.
I'm not sure you can see it in the picture, but I have marked the sketch with depths for a rough guide as I start to construct these. This is of course just a guide and I can tweak the design as I start cutting if things don't look quite right as I progress.
I plan to construct these out of 1" pink foam insulation. I picked up 3 sheets of foam at my local building supply store. My next step will be to start cutting these.
Stay tuned to hear more as this project progresses.
