FSQ106 - Flex in focuser

Has anyone done any maintenance on the stock Tak focuser?

I have had quite a few issues using the STL11000 with the stock focuser. The Robofocus was not up to the task and would refuse to lift the camera on most occasions. I've ordered a Bellepheron which should be here any year now - its been ready to ship almost for weeks now.

Anyway, taking some images and manually focusing, I had a look at CCDIP - there is some serious tilt involved. Rotating the CAA, its clear that the tilt is a result of flex in the focuser drawtube.

I came across this article

which looks a bit full-on.

Has anyone else found they needed to resort to this?
