The biggest consideration when building a rotating gap is rotational speed. 
You need to calculate the forces that are trying to pull this disk apart. 
The electrodes are located on the Circumference of the disk. This creates a 
tremendous moment / force (Centerfugal force) which tries to pull the disk 
apart. Since most disk have an insulator at the center (Low strength) it is 
important to know what theses forces are so you do not over stress the disk. 
In addition to this a liner gap is much easier to construct and it will work 
fine at low power.
