For today's TMS activity under the cartridge test stand, I clamped the PenRe (the mass most vulnerable to bumping, yet also the most robust), plut the face shields on the ERM and ETMy, then bagged the suspension.  The main chain is theoretically* hanging free (* the clamping of the PenRe could have pushed a reaction mass into a main mass).  This is how the suspension will remain until further notice, due to TMS installation.
