[QUOTE="archive10, post: 990682"] Having examined the scans you so graciously have uploaded, it seems that the strut mounting in the upper plate of the mount at either D1 or D2 seems to do with the motor being left- or right-hand mounted (when seen from the back). Left in the UK, right east of the UK (presumably left in half of France - that's got to be in the maps you omitted). From the text, it seems there is not mechanical difference between the two. However, scrutinizing the actuator configuration, I can't quite see what the difference is. But I am sure there is one, otherwise they probably wouldn't have gone to all the trouble of making two separate mounting holes at the top. Is there an aligment difference? Hard to tell... The bottom mounting point for the strut is different though. If I understand your messsage correctly, you have now mounted the strut in the edge hole, not the central one. Well, mine's attached to the central one. [ATTACH=full]99300[/ATTACH] Do you think it should be attached to the edge one? It is clear that there will be a slight difference in the angle between the upper and lower plate of the polar mount depending on whether the central or edge hole i used, and a resulting declination difference. But which set of holes is the right one?? It seems to me, that since we need to adjust the declination anyway for non-SMW dishes, the main thing is the alignment of the lower and upper halves in the vertical axis. This clearly will be affected by using either the central or the edge hole. A better balanced mount will give smoother action across the arc, I assume. Empirical evidence will eventually prevail, I am sure. [/QUOTE]
