The booklet from Lindsay Publications is  Metal Spinning by James E.
Reagan and Earl E. Smith.  The copyright date is 1936.  Frankly, it
doesn't look like a job for the rank amateur.

Ross Engineering - Campbell, CA 95008 (408) 377-4621, FAX (408) 377-5182
sells toroids and spheres as well as many other HV goodies.  Their
toroids range from 2.95" to 42" diameters.  I haven't seen their prices
but I guess they are not cheap.
