Subject: Motors mounted - first attempt 
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.
