i am working on a vandercook 4 serial nr. 15900 that i bought a couple of weeks ago. when inspectiong the press i realized that there is a strange thing inside the cylinder on the operator side. see pictures. the other other thing was next to rust a broken pin on the foot pedal activator fro the gripper bar. i could take care of this and now i took the handle off and the collar and unscrewed the bolt inside the cylinder. the shaft is connected just by friction with 3 big fender washers to the cylinder. i know this press tipped on the side in his long life. how does the original connection handle shaft to the cylinder look like. i think there should be a square key or a woodruff key.
thanks for your help
