[QUOTE="Vipersan, post: 741498, member: 325666"] Hi CH .. The pictures pre-disaster can be seen in this thread [url]http://www.satellites.co.uk/forums/threads/added-elevation-control-to-the-1-8m-dish.141456/[/url] post 7 I know its a bit crude ...and in an ideal world the pivot bolt should be fitted with bearings ...but if left untightened ..just enough to allow the small amount of movement neccssary it works quite well.. ie ..no binding at all .. My worst fear is wear between the pivot bolt and the mount itself .. ..but of course it doesn't get moved that often so movement is only occasional and minimal I examined the mentioned pivot point for wear when I dimantled the mount ...and didn't see anything of note.. also when I took the declination jack apart ..it was fairly obvious that water ingress was the culprit ..and that rust had seized the worm ....and that driving the motor against the rust had destroyed the bearing race.. rgds VS [/QUOTE]
