Thanks Gene,
Amazon says it will be here on Tuesday so doesn't look like it will be an 
issue.  

The bigger problem for me at the moment is I put a dial indicator on the 
harmonic drive output hub and used LCNC to spin the A axis.  I then radially 
measured 0.0015" deflection and same with the face which also had 0.0015" 
change over one rev. 

Maybe it's dirty inside or has been reassembled poorly.  But that's a lot of 
runout I would think.

John
