The "pyramid style" base cabinet is manufactured from ultra-durable and tough 13-ply Baltic Mahogany plywood.
Inside the box is visible the Quad CM-600 Power Inverter and Power Supply.
Sitting on top of the special micarta cradle (we'll talk about this later) are the various "cuts" of Polycarbonate (Lexan) material that will be used for building and assembling the high voltage parts of the coil. These pieces were precision cut on a water jet table to insure accurate assembly.
Note the "tombstones" on the right of the pile. These will support the actual weight and stress of the secondary and accessories. These "tombstones" (so named after their shape) are a very critical key component to the structural integrity of the bipolar coil.
Polycarbonate was used throughout as the material of choice due to it's superior strength compared to ordinary Acrylic. This is important when you consider that you might have to actually move the coil safely across the floor!
A closer look at one of the tombstones attached to the drilled and tapped micarta cradle.
2 x 4 inch phenolic resin plywood (micarta) was used for the cradle assembly. Cutting the grooves in the micarta required use of a milling machine. This material is physically very strong, made for very high voltage withstand and resists weight related warpage far better than anything else we could find. Besides; it's got a "cool wood grain" to boot.
Here's a look at the coil winding jig and the finished secondary coil winding
