Hey all you smart guys.  Why can't the apex groves just be welded up and a=
 new groove cut?  Welds are supposed to be as strong
as the base metal or stronger.  It is not a "new" technology.  EDM machining=
 has been recommended to cut the grooves to 3 mm so
what am I missing?  Is there a better way to do it?  Cheaper alternative?   =
 Cast our own rotors?  Tell me more.  Talent and ideas are
not in short supply on this list.
