I need to load a series of tubes onto the track rod (mount is to be developed). The track rod is a tapered helix. At any given moment, I need 30 instances of tubes to be 'staring' dead center to the orb (sphere, ball, etc). The spacing between the tubes should be equal. The lead in and lead out of the tube can be oriented in any direction. The contest is to make the tube axis to always be looking at the center of the ball.
Many thanks in advance
