Design calculations are extremely simple, given the geometry of the
core. Look in any decent electrical engineering handbook. For that
matter, look at the reference material in the Amidon web page
for material on calculating flux density from turns, frequency, and
voltage. Most of their examples are for ferrite materials, which have a
relatively low saturation flux density (in the vicinity of 4000
gauss)./ Transformer steels can easily be used up to at least 15,000
gauss. Calculations of flux density are easy, and if you have wire
tables you can easily calculate what the windings will look like with
different wire sizes.
