Joe the Camera will not stay there it is mounted on the polar shaft which in turn rotates at 1 revolution per/minute in accordance to the equation of the curved bolt tracking device.

This Machine was built with a curved ¼” threaded rod arrangement with a pitch of 24 to the inch, and set at exactly 242mm from the center of the main angled shaft supported through a bearing set-up, and one RPM small electric motor, I found this in an American Astronomy Magazine many years ago.


Radius = 1436.5 x ( n/2 pie t ) where n = 1 and t = 24
Radius = 1436.5 x ( 1/2 22/7 x 24 )
Radius = 1436.5 x ( 1/6.285714 x 24 )
Radius = 1436.5 x ( 1/150.85713 )
Radius = 1436.5 x ( 0.0066287 )
Radius = 9.52212 inches, (241.86184 mm)

Apparently this set up according to others works very well for reasonably long exposures.

Thanks for looking
