[ATM] Ronchi images and a sphereical surface

["Russell Jocoy" <russjocoy@hotmail.com>]

Dave,

     Your photos tell ten thousand words.. Photo # 4 showed a nice 
sphereical image..
straight lines and no turned edge. If your goal was a sphere,.. you passed 
it by.
    It is much easier to go back to a sphere , than to figure to a 
paraboloid. The sphere is
the natural process of polishing with correct rotations, and correct 
strokes, and correct lap
contact...          You are close to being done my friend......  Russ Jocoy
