[PSUBS-MAILIST] Dive fail.

Mon Jul 6 09:49:38 EDT 2015

Thanks guys.

I have already fixed the problem.  Ive just stuck the widows in now with
sikaflex.  I didn't want to do that to start with as I wanted them to be
able to come off for maintenance.  But now they are stuck forever.....

I used a different method for filling the aft motor.  I have 2 tubes coming
from the potted original shaft that act as the fill and vent.  With the
talk recently of "zero bubble tolerance", I filled the motor as much as I
could, then filled an ice cream tub with oil and stuck the 2 pipes under.
I could then flush out the remaining few air bubbles and get the plugs in
all under the oil.  Zero bubble.  Also the vents I put in the side
thrusters allowed for proper filling.  I am confident I have no air at all
in any of the 3 motors.
