I do go through and throw shit away periodically.  This particular motor
will be used on a Hurco CNC mill if its good and I can figure it out.  (The
motor not the mill)  I already manufacture some parts on smaller CNC mills.
Mills that I have gotten way more work out of than they were ever intended
to produce.  One of the first things this mill will get used for is to make
parts for some intermediate size specialty machines.  Well... if I ever get
it retrofit to a modern control system, working and tested.  Actually, the
first thing it will probably get used for is to make servo motor mounts for
my lathe to convert it to CNC.  It would sure be nice to be able to turn
threads in hard material without standing over the lathe constantly.

None of this has to do with alarms, but I figured somebody here was a motor
wizard.
