Need to clean the secondary on my ES 12" dob. (1)To remove it do you just hold on to the secondary on the sides and unscrew the 3 knobs? (2)Anything else fall out when you do this like springs I assume?.. (3)Also putting back I any measurement I need to take to get it back close to the original position?
(2)yes, so watch where the springs go and make sure they don't get lost.
(3)measure the gap between the plate attached to the secondary and the plate pinching the spider blades. When you put it back, start there.
This technique works fine:
