Hi All and thanks for reading.

When I luffed-over my 6 year old V160HD for it's annual maintenance check, it struck me just how sloppy all the various jointed sections have become. It's not that the securing bolts have become loose, they're still firm and tight.

As owners will know, there are two doughnut shaped shims per section joint to adjust for the difference in tube sizes and it's the play between these and the tube ends that's the problem. I don't remember there being between a half to one mm gaps around the circumference in the past?

I don't know whether new shims would fix it but Titanex no longer answer emails and I wouldn't know where to start trying to find an outsource willing to make me a few new ones to the required tolerances.
Adding any more guys than the set I have at 12m is also a no go.
The only thing I think may help, is to try increasing the tube overlap at each joint from the present nominal 5 inch to say 10 inch or more?
Possibly adding an additional bolt at each joint also?

I wonder if any other Titanex owners have had this problem and have any advice to share please?

Many thanks in advance.
