This is a real cutaway, right? With a little stop motion videography work? Not an animation. If so, while it's not an extraordinarily complex tool, it's a great demo. Cutaway, plus the different colors, plus the upclose shot. Great teaching tool.
And you can see why a bottle jack is so slow...
Trick: Use the lowest ton jack for the application. A 20 ton jack takes twice the number of strokes to move the same distance as a 10 ton.
For my rocket press I used a 6 ton, all I needed and fast pumping.
I replaced the hand pumped 20 ton jack on my HF press with the air over hydraulic unit and a foot operated valve. Very fast now...
