Comment stsetch SNF 2005-03-12 19:05:00: Piece removed, machine ok

[ericp at snf.stanford.edu]

I removed the broken wafer piece, changed the lip
seal, and changed the chamber top o-ring.  The top 
o-ring was bad.  (Old lip seal may still be usable, 
I'm leaving it in the STS cart.).  Chamber cleaned and
wiped.  WILL NEED O2CLEAN and SEASONING 
before use.   Leakup is <1.5 mT/min (only shortly 
after vent and IPA wipe of ceramic).
