This work, building upon T.N. Lockyer’s Vector Particle Physics (1992), presents a simplified geometric model for the proton and neutron, enabling the calculation of the proton-to-electron mass ratio (mp/me) with remarkable accuracy of seven significant digits (mp/me ≈ 1836.1521964, relative error −2.6 × 10−7) compared to the CODATA value of 1836.15267343. The neutron-to-electron mass ratio (mn/me ≈ 1838.68982960, error 3.35 × 10−6) yields six significant digits.
