> HPS room,
> 1.  Install 3 screens into each of 2 HPSes.
> 2.  Insure new pilot check valve is installed, if it isn't, get it

> 3.  Remove orifice from 3rd main return valve.
> 4.  Use correct color brown paint on commoning tube between HPS 1 and
> 2.
> Vertical Actuators
> 1.  Install new LVDT rods.
> 2.  Replace Z1 and Z2 swivels, return old swivels to MTS America.
> 3.  Remove paint and counterbore for all swivels, top and bottom.

> 1.  Move accelerometers.
> 2.  Install new wings, insure all paint off of mating surfaces.

> 1.  Update table.dat for new accelerometer location.
> 2.  Retune bare table.
> 3.  Do additional training.

> 50 Hertz also but at the smaller specified g level.
> 5.  Redo Ito's diagonstic tests, i.e. measure transfer function, from
> Z to mid point on Horizontal actuator and to table wing.  Hopefully
