Yeah! A real pain, but I've already had it apart about 3 times (I won't go into why, it's just too painful to talk about), so I'm getting pretty good at it. I got a suggestion on another board to cut off just enough to not engage the lock ring but still engage the tube that it slides back and forth in. This sounds like a real good option, you know just in case it does provide stability to the rack.
