After some horrible movements in the mount and some nice crunching sounds, I am FINALLY going to attack mine with a screwdriver today.
I am not bothering with pre-tune results, but
http://completelyserious.com/pics/mountts/IMG_4672.JPG should give you a rough idea of how bad the movements are. (This is a guided shot, while tracking the stars will occasionally jump around in the eyepiece).
Fingers crossed it doesn't go completely wrong..
