just wondering if anyone had any tips on how to un-stick the telescopic ends on a boom
cheers 
Depends what's sticking it, if it's salt, it may come good with a good long soak. Sand is another ball game.
If you can undo either end, than you can twist each arm. If not all that's left is brute force, with a bit of vibration.
Bang it in bang it out, not with a steel hammer though, hard rubber or soft wood preferably.
I was given a boom that was stuck..someone sprayed it with WD40 & waited & bashed ,pulled etc and it came good eventually..been ok ever since
My method: put one end over a street sign lamp post etc. tie the other end to the tow ball of your car, apply accelerator hey presto its apart.
Do it with 2 cars going in opposite directions could be even more fun. Gotta keep it fun thats what its all about.
clamp two masts onto it and twist? Oh hang on that is two booms for a stuck mast 
hey, congrats on the first ever stuck boom thread as opposed to the 20 stuck mast threads we've had in the last year!
seriously....
stand it up on the front end, apply WD40 or RP7 around the tubes and allow to soak in.
Then use the car method - carefully
make sure you degrease inside afterwards to remove the WD40 otherwise it will dribble out with the water after a sail and make everything icky
EDIT: notice sboardcrazy beat me to it....
..
I'm impressed that you lot managed 8 posts without making the connection between the boom being stuck and the location of the pain.
well done for taking it all so seriously
i think before useing the car method mabey try hooking the clew end around ya towball of sign post and yank it or use block of soft wood and hammer
