Mounted both  motors on CARME. Started 
with outside motor.

M6x160 screws proved slightly too long to 
fix bellows to rod and seal the vacuum. 
Had to be manually shortened by 1 cm 
roughly.

Mounted whole assembly but could not fix 
actuator rod to moving plate due to holes 
mis-alignment.

Mounted motor on CARME but could not align 
holes on flange and chamber without 
turning motor to the side... see attach 3 and 4

Got in contact with Peter over lunch and 
understood issue.

Mounted second motor with experience 
acquired. No issues. All screws go in. 
Motor box level. See attach 5

Will need to dismount / remount first 
motor box before pumping down. Currently 
secure on CARME thanks to adjustable 
support.

Note we forgot to buy DN 40 CF gaskets. ML 
supplied a few. Will buy more. Needed 
between bellows and rod.

Strain relief mentioned in previous ELOG 
entry was taken to workshop and hole re-
drilled. Workshop reports other hole is OK 
for M3 screw. Either screw used or hole 
were poorly machined. M3 screws should be 
correct. Re-machined part sent for 
cleaning.

Will try with clean parts again tomorrow 
unless we remount motors.

Activities for the day cut shorter due to 
SPARC meeting this week.
