[Curtis A. Meyer]

Hi Tim -

      The small part that we received from Meyer (10 days ago) does not 
need to be reamed.
It is in spec on the hole sizes and the pins fit through without 
pressure. We also note that
our 0.4370 pin gauge slides through on its own.

     This was not true for the CFIB endplate when we checked it at CMU. 
However, after we
have finished reaming the CFIB endplate, we believe that it will be the 
same. This job
is over 50% completed now.

       Based on the original plastic samples for the feed-throughs that 
we got from you at the
collaboration meeting, those will fit fine as long as the endplate holes 
are reamed out to
the spec of 0.4375. Thus we are quite happy with that solution.

       We will be carrying out our glue check fairly soon on the with 
the small parts that we
got from Meyer tool about 10 days ago using the plastic parts we got 
from you at the
collaboration meeting.

   cheers -  Curtis
