LCI requires the Revision 0 design.  This design was submitted to, and accepted by, LCI.  The blade plate does not need to be machined.  Nor does the hinge plate.  Mill a slot in the hinge plate for bolting to the blade plate.  Tack weld the hinge plate to the blade plate and tack weld the bolt in the hinge plate to the blade plate.  Mill finish on the blade plate is acceptable.  If unable to provide this rotor design, please let us know as soon as able so LCI can make other arrangements.
Thanks, Brad
