Ive made the dies and operated the presses, big and small.older than those. no real safty execpt for brains. I remember the 2.5mm thick, by 150mm wide brass in a 3 foot dia roll and just stamping away,,,what a noise.boom boom boom...the entire shop moves...not real good for the cnc mills running, but when doing aircraft stuff on the mills.the press was usualy not being used. I some time miss doing that stuff...especially when I need to make something and have to think read dro and use the hand wheels instead of programing and pussing a button.
