Building & Using a Tracking Mount for Astrophotography
Further Tips For Construction
Another key feature of this mount is that the distance between the center of the hinge pin and the points where the curved drive rod penetrates the two plates must be exactly 7.14 inches. This is necessary so that when the nut (attached to the large gear) is turned at 1 revolution per minute on the 10-32 drive rod, it will rotate the upper plate and camera at exactly the correct rate to match the sky's rotation.
The image above shows the drive rod penetrating the upper & lower mount plates at a 7.14-inch distance from hinge pin.
