Re: Pivot arm or telescoping-pivot arm?
I would say that without some other form of extension you will only be able to receive tubes from the slot, it is possible using a very well designed grasping apparatus to score on all three levels with a simple pivot. The problem only come if you happen to drop a tube... Thats my input.
I would also do some quick math to figure out if your design allows you to score on both the upper, lower, and middle parts of the rack.
