Peter, that's me, would love to learn machining, but you are right, I can't
afford purchasing a large lathe (or small one).

Some more background, the wife reported grinding in the brakes.  Half of one
surface was scored but not deep.  I might have just installed new pads, or have
the rotor turned.  We had this one turned before because it was slightly
warped.  There was a little hint of warping before the grinding.  Turning would
have weakened the rotors.  The cost of a new rotor was $19 and turning service
was $15 (search could  have located a less expensive shop).  The $4 dollars was
worth not waiting.

After advice from this group, I will never have rotors turned again.  Thanks to

Peter Thomas
