This time, I am thinking - remove one of the two sections of track, and

the chair could be dropped onto the track anywhere, then just have some
sort of bottom retaining clamp fitted.

I have spoken to Stannah, who are not very helpful, quoting Elphin
safety/ the world will stop spinning etc., they will remove for a fee
and reinstall for a fee etc...

Anyone know for sure the process please?

I did a minivator one... that involved manually winding the chair off the end
of the track.

Yes, it is all pointing towards doing that - thanks, if I it does in
fact have to be taken all the way out.

I have several times looked on Youtube for a video for the Stannah
process for my model and found nothing yet.

However - The carpet guy has just been to look and what he is saying
they usually are able to do is...

Wind the chair to the top, undo all but the top bracket, lift the track
plus chair to do the bottom, then chair to bottom to release top
bracket for the top carpet laying.
