What do the heavy balls do for getting a feel for the work?

The balls just store the energy you apply to the handle when

around and that energy is released when the tooling strikes the
It's normal to keep a hold of the handle so you feel the interaction
between the tool and work, not always required but it's nice for
things. The balls and fly presses come in different sizes depending
the job requirement. The ram runs in precision guides so location is
consistent which is useful for thing such as punches and dies which
have a decent selection of, once the bolster has been located to
the die the punches and dies can be swapped quickly and easily which
really useful for the likes of punching holes in sheet metal.

They still make the things new in the UK .

After putting my pea sized brain to it..I can see some processes
they would be handy indeed.

I have a Dumont 5 ton broaching arbor press and a 60 ton hydraulic a handful of small arbor presses....and of course a
couple sets of Greenlee hydraulic hole punch dies and hand pumped
power sources. Is there any reason for me to find one of those
presses as you discussed? If so..I will most certainly start hunting
for one;


I'd rather dedicate the shop space to one of these:
