Mine isn?t woking anyway so I want to remove it. I think it broke somehow when it was a little tightend some years ago.
When I turn the knob now, I can see the nut in the other end turning - but nothing happens with the friction plate..
Have tried to hold the nut and unscrew it with the knob , but it?s stuck- REALLY HARD.

Any advises ?

And if I get it loose, do the parts come loose easily ? what comes loose ? only the rod or the friction plate to ?
