Bograt,
Being a CLO and volunteering are two different things.
Being a CLO,   you usually don't work directly with the cadets but you are in charge of  « opening doors  » for the Cadet units, directing the CO's on the how and when and who of their request for support from you own Squadron (If a unit needs personnel, supplies or use of your building for example).   The reverse is also true : if your Squadron need the support of cadets for a certain activity, you would be in charge of contacting the Cadet units.      
The only tips I can give you are :
 - 
Be available.   Nothing more frustrating then not being able to contact the CLO then having to go directly to some other guy who will ask  « Why didn't you ask the CLO ?  »   
 - 
Be patient.   Not all CIC officers have a great understanding of the resources, capabilities and organisation of a Reg Force unit.   You might have some explaining to do.   On the other hand, they might have to do their own explaining because not all Reg Force officers have a great u understanding of the resources, capabilities and organisation of   a Cadet unit   
 - 
Good communication is also key.   Make sure everyone understand what you can and can't, do and ask the same of the CO's of the units you're supporting.   
Volunteering in a cadet unit on the other hand requires you to perform a certain function in a cadet unit depending on you available time and qualifications.   In that case, go to a local Cadet unit and volunteer directly to the CO.   You might get something "full time" or just give a day or weekend here and there to give a hand for something specific.
Hope this helps.
