     Rev.  11-December-2017


     This work is for Wade Fisher on account:  RC104022


     Please make  24  more of the  Filler Blocks  for
     the Hub FPGA heat sinks.


     You made an initial run of these parts in April or
     May of 2017.


     There is  one  change in the design of this part
     since the batch that you made in the spring of 2017.

        This change is the addition of a 2 mm deep by
        17 mm long notch that is cut into one edge of
        this filler block.

        This new notch is show in a separate drawing.

        There are no other changes since the parts
        that you made last spring.


     Material Supplied:

       - An example part from the initial batch
         with the new notch added to it.

       - 1/4" x 2" aluminum bar stock


     Please let me know of any other material that
     you need for these parts and I will order it.


     Delivery by February 1st next year is fine.


     Please email or call if there are any questions and
     I can run right down to your shop to discuss things.


     Thank you for making these parts,

                Dan Edmunds
