I along with many others on this sight am a big fan of this handle when working well and could easily chuck it when its not. I have replaced the failing bush on both of mine despite being very careful to keep it clean and not to over tighten.
I've spent more than enough time pondering a solution, something which seemingly Drennan have not. The male thread is M10 and I decided to cut down the top (inside) end of the bush down, araldite on a suitably sized M10 nut onto the bush on the metal thread to metal thread is better principle. It was difficult to find the nut but once found I then ground off the corners of the square nut so it fitted inside the handle once fitted to the thread.
Unfortunately the araldite struggled to firmly bond the two together and at the first attempt they came apart, hadn't expected that. I was pondering my next move and offering the parts together when I had the EUREKA moment.
Having ground down the top of the nylon busy to allow for the thickness of the nut I had obviously reduced the internal thread length of the nylon bush.This effectively allowed the tapered male thread to insert further into said bush increasing the diameter of the flared section of the bush beyond the width of the external tube. By refitting the internal tube from the top, minus the bush, I then removed the cap from the bottom pushed the internal tube a couple of inches out of the bottom and screwed the now shortened bush onto the male thread. Obviously it now does not travel as far up the male thread before expanding. I screwed it in until it was a tight fit the worked the inner section back into the handle, now a tighter fit and hey presto perfect, it is a little stiffer to open to extend the handle but once quarter turned locks beautifully.I would estimate I removed between one and two millimetres from the top of the bush.
A bit long winded but hope this helps someone out there.

is not to over-tighten it when new. But if you do, order a new expanding collet from Drennan (FOC) and do no to over-tighten it. But if you do..........
