You want to talk to Andrew Worsley aka HQT about harmonics. He wrote Harmonic quintessence and the derivation of the charge and mass of the electron and the proton and quark masses. That's in Physics Essays Jun 2011, Vol. 24, No. 2 pp. 240-253. See this web page. He’s applying "spherical harmonics", usually applied to electron orbitals, to the particles themselves. Look at this depiction of a spindle-sphere torus and imagine an "equatorial" rotation going round at c and another orthogonal "polar" rotation at ½c:

This rotation is reminiscent of a moebius strip, which you can "inflate" to give the Williaamson / van der Mark electron, which you can "inflate" further to the spindle-sphere torus. IMHO this fits what we know about the electron. It has a spherically symmetric electromagnetic field, and is a spin ½ particle where 720 degrees are required to return to the original state. Andrew gives the electron Compton wavelength as λ = 4π / n c^1½ metres, where n is a dimensionality conversion factor with a value of 1. Here's the numbers:

4π = 12.566370

c = 299792458

c^½ = 17314.5158177

4π / c^1½ = 12.566370 / (299792458 * 17314.5158177)

λ = 2.420910 x 10ˉ¹² m

Actual = 2.426310 x 10ˉ¹² m

There's a binding energy adjustment, but it's small.
