I recently finished some new Wild West Exodus-themed terrain. Here's a look at the pieces in progress. You can see more detail shots of the finished terrain in my Wild West Exodus terrain gallery.
Old West Church
The construction uses a foam core frame, with basswood siding and framework.
The doors are my own resin-cast assets, and the windows are Grandt Line plastic accessories.
All the wiring is made from heavy gauge floral wire, with resin cast tech accessories.
The roof is covered with plastic card "sheet metal" and lifts off for access to the interior.
This water tower is constructed from basswood planks.
The water spout is made from plastic tubing, with more resin tech parts. One of the best things to happen as a result of the Steam Punk craze is all the costume accessories now available at craft stores. Things like these little gears and clock faces are great for terrain.
I made the roof of the water tower with plastic strips for the support structure and wood chits, scored with a wood grain for the shingles.
