UPDATE - While this concept looks interesting, it appears the theory is lacking. The attached diagram presents rules of thumb that has been shown to work in a number of cases. However, there other constraints that are not understood. My version and one other, both of which met the criteria presented, proved to be unstable.
Dean Black put together this nice diagram describing the design of an induction stabilized rocket of constant diameter. As they say, a picture is worth a thousand words. It appears that I can shake the lead shot out of the Inductor's NC. Woohoo! E9, baby!
