Abstract The solutions of the Einstein field equations, previously used in deriving the self-energy of a point charge, are shown to be nonsingular in a canonical frame, except at the position of the particle. A distribution of "dust" of finite extension was examined as the model whose limit is the point particle. The standard "proper rest-mass density" was related to the bare rest- mass density. The lack of singularity of the initial metric g/sub i/sub i was in contrast to the Schwarzschild type singularity of standard coordinate systems. Solutions for the extended source were nonstatic in general, corresponding to the fact that a changed dust is not generally in equilibrium. However, the solutions became static in the point limit for all values of the bare-source parameters. Similarly, the self-stresses vanished for the point particle. Thus, a classical point electron is stable, the gravitational intersetion cancelling the electrostatic self-force, without the need for any extraneous "cohesive" forces. (auth)
