i've searched the archives but can't find the answer. I have a "duel sail system" telescoping tiller ext. its 7/8" in diameter and ranges from 66-125". I had a pretty good wreck 2 days ago and since then it won't engage the extension lock mechanism. i've tried all sorts of things to take it apart but can't unlock the puzzle. the grip end is 5/8". when i look in from the bottom i see a plastic "disk" blocking the way to the extending tube. i suspect this has dislodged from the inside tube. i can get it to move with a dowel but it won't "snap" back into place. I've tried knocking it out the bottom by hitting it from the top with a dowel. no luck. the inside tube won't come out the end and the "disk" is keeping it from coming out the bottom. is there anyone with some experience taking this one apart????

thanks
