Graham Phantom ceramic armwand 'twisted'?

Hi folks,

I've searched around for an answer to this but haven't found one, but apologies if it has been answered elsewhere.

A couple of years ago I acquired a secondhand Graham Phantom but have only just got round to mounting it on my Avid Acutus (SME mount).

I was using Feickert's Adjust+ to adjust the azimuth, and having difficulty getting the measurements to 'converge'. The best, but still suboptimal, position seemed to be with the azimuth adjustment turned all the way to the bottom, so that the arm pillar is leaning in decidedly.

On closer inspection, it looks like there could be a 'twist' in the armwand. Is this possible, and have there been any other reports of it? I have read about ceramic armwands breaking if they are dropped, but not twisting.

I have contacted Graham by email a number of times but with no reply. (I am in Finland so calling is not easy.) I see there is a very small Allen-headed grub screw on the underside of the armwand and I wonder whether I might be able to loosen that and turn the armwand to counter the twist, but this seems a bit haphazard.

Any thoughts, experiences and advice much appreciated.

Cheers,

Rich
