While this is not about model building per se', it is about interesting machinery and may be of interest to other board members. One of my local customers manufactures industrial heating elements. Last year I designed a series of cooling conveyors to cool the elements after annealing them, and used a pneumatic gripper and a pneumatic guided cylinder to pull the tail end of the heating element clear of the annealing furnace. I used 3 pneumatic cylinders to rotate a shaft thru a partial arc to move what I called my "Pin-ball flippers" thru an arc to side discharge the heating elements onto a cooling conveyor. I had to go and see that customer in regards to designing another machine today, and while I was there I made a video of this simple pneumatic automation working, for my own records. The "element" is the 5/8" round rod, the annealing furnace is blue, the outrun conveyor is a series of non driven rollers, and the cooling conveyors (which can only partially be seen) are a series of powered roller chains which move very slowly and let the elements air cool. Hope you find it interesting.----Brian
