PPM's are great if you have $4,000 for one...

Hi Jim -
In defense of the PPM's - Have you ever opened one up and seen how they're
built ? I would guess that any motor shop could rewind the "coils". The
bearings and brushes are obtainable. The gear box, if tended to, should last
forever, or at least have replacements available for longer than any of the
current rotators will be supported by their manufacturer or NEMA. They may
be an overkill for many of the jobs they're asked to do, but my guess is
that they will outlive most of us who are using them.
Gene / W2LU
