I've seen someone press skillet pans cold with a 20 ton fly press, so I was curious if using one of those bottle jack h frame presses would work the same? Of course its wouldn't be a permanent solution, but you think it would work? What are the advantages of a fly press compared to one of those hand cranked presses, given they are the same tonnage?

 

Thanks

Speed is your friend when stamping metal parts.

One thing with a screw/fly press is that there is a spike in pressure as the ram bottoms out and reverses.  Why they are good for coining.  The rate the pressure increases makes a difference when forming metal.
