The main idea was to create a proper forearm trainer, using the mechanical advantage of appling the weight out of the center of your hand makes it way harder, so you can reach failure with just 5-10kg by doing 12 reps.
I've done a few variations and this is the one I am the happiest about.
The steel cable should be 3mm in diameter, but its made to accept one a bit bigger. It should not be shorter that 60 cm in order to have a complete range of motion.
It has the hole for four 2.8mm in diameter screw, but in my testing they are supper optional. the length that I've use is 30mm.

I recommend also using 2 crimping loop sleeves.
