[QUOTE="dreambox1959, post: 1145557, member: 314801"] on most polar mounts the elevation cylinder replaces the original threaded rod, but it is placed in such a way that the stroke is very short. If you can create your mount, you must increase the distance between anchor points for more precision. in your example of a travel of 5cm or 2 inches, the cylinder screw will make 2x8 turns or 16 turns with perhaps 48 pulses per inch, it is really very little!! the 36V motor can be run at 18V so that it moves slowly. I spent a lot of time adjusting my polar axis and declination as well as the South direction on my polar mount and I never touch the elevation. [/QUOTE]
