Hi Josh --

My sneaking suspicion is that someone may have inadvertently partly
unscrewed the segements and that the innermost ones are still inside the
vacuum chuck.  At least, this has happened before (several times.) That
little red plastic toolbox behind the wafersaw (which contains the
resinoid blade hubs) also contains a long metal screw thread.  This is
Elmer's solution -- just screw this into the vacuum pin slot and fish out
the pin segments.  Please let us know if this doesn't work.  Otherwise, I
would recomment taping (if you can) your small piece on a larger wafer.

GOod luck!
