Of course.

Why not? What is going to limit how much torque you can apply, you just get
a machine with a beefier tool and press attached.

That's probably just because you can't get a good grip of the twig to apply
enough torque, sandwich it between two huge steel plates, both with a step
in them, then apply 10 tons of force and I think you will see that the twig
can bend :-)

Some guy sitting at a computerised milling machine I would imagine.
And yes, how do you make that, etc etc I think at the beginning someone had
to make something with their bare hands :-)
