Is it possible to do something like a cam mate but without a closed contour? Kinda like a stylus following the grooves in a record or the pins in a lock following the profile of a key??
I'm working on a push-pull knob assembly that's got a ball-type frictioning device in it and I need the ball bearing to follow an extruded cut on the knob's shaft as the shaft moves in and out of the housing.
Thx!
