This week sees the conclusion of the tutorial on how to build a display board. Before we proceed let's look back to week two, where we started work on the chaos warp gate. In week two we went over how to start the foundation for the warp gate, now we'll continue where that post left off.
Before we get started we'll need these materials:
3. Box cutter
7. Dreadnought base sized hole cutting bit
8. Monster base sized hole cutting bit
9. Infantry base size hole cutting bit
10. Hydrocal plaster
From our previous work we have one layer of the warp gate complete, but we want it to have more depth, so we'll proceed by tracing two more complementary layers to attach to the base layer.
For the second layer I focused on building an interior to the gate's energies by cutting tendrils that reach towards the center. This will work to make the piece appear less linear.
The third layer will add dimension to one side of the gate. Don't worry about bridging the left and right sides with an arch, they will be attached independently to the gate on their respective sides.
With all three layers cut out place them and see what layering order looks best to you. This was my original order. I decided that the central layer would contain the gate's sole arch and use the other two layers to add depth to the piece.
To shape the foam, cut off the hard edges with an xacto knife. This will make smoothing the edges and making transitions form layer to layer much easier.
Use a fine grain sandpaper to sand the piece. Folding the paper to differing widths allows you to create broader and sharper grooves. I held the paper loosely and sanded recesses around the "tendrils" to give them prominence. After that, I folded the sandpaper tighter and created sharper detail grooves. This process emulates the undulations you might expect from something that is semi-liquid or energy based.
The initial shaping of the gate's levels shouldn't be 100% complete before assembly. Remove any unwanted hard edges and get the basic flow you would like to achieve first. More shaping for the gate's final appearance will happen after you assemble the layers.
