It all looks fine to me. No glaring issues. The 4.7 inch diameter is
fine for the 10/48 NST. You probably will want to raise the toroid to
about a center line of about 51". Your secondary turns are dependent on
heavy build insulation of the magnet wire, so be sure that is what you
use. But cap size, coupling, ratios, and distances all look good to me.
Also, once the coil is wound, update the program with actual turns of
