Solved - Novice EQ1 question. re RA motor.

[Starslayer]

I have added a simple RA motor drive to my EQ1 for some simple planetary  'work'.  Should I be clamping down the thumb screw whilst the motor is running? It does seem to turn regardless of whether this is clamped down hard or not. ie I can see the other end of the spindle with the fine adjust wheel attached actually turning slowly.  Thank you

Edit - ok I may have answered my own question. It seems like the worm drives the lower half of the axis 'disk' only. The thumb screw is to lock the top half. With it loosened off I still cannot turn on ra with the motor turned off.  

I cannot delete the thread so shown it 'Solved'. 😉
