The tesla coil needs a base that can support the electronics and the coils itself. We built ours out of 2x4 and 1/2" plywood. The base also has 2" castors in each corner of the base for movability. Here is a photo of the sanded, unpainted base:

Here is a photo of the castors on the bottom:

Finally, the base was given a coat black spray paint, and yellow accents for the corner. Here is a photo of it being painted:

4 2x4's are cut to size to provide the vertical supports, and the top plywood is cut to 29 1/2" to provide adiqute space for the primary coil.
