UFO conversion options

[Bernie Benz]

Peter,

The electrolite in the electroplating process is a solution having a finite
electrical resistance.  Therefore the metalic ions will tend to travel a
path of lowest resistance, the shortest distance to the cathode, and are
dispersed only by the mutual repulsion of like charges.  That's why, when an
extreemly uniform deposit is required, a shaped anode is used.  The bottom
of a semispherical indentation in a flat surface will recieve about 10% of
the flat surface deposit eminating from a parallel flat surface anode.

There are some limited nonelectrolitic plating processes that may be better
suited to the deep holes of the rotor cooling passages.  Research it.

If not careful, one can learn something new every day!
