Hi Alan;

Actually technology similar to this is used for a number of things. I
do remember one company turning pistons just slightly out of round so
that they would expand evenly when heated up. Not really up on the
details. Things like cutting optical toruses are at times done this
way. Of course things like this are often patented so you don't hear
alot about it.

It certainly is not usefull in a world where you strive to get round
features but there are places where roundness isn't correctness.
