Some details:
The temporary trigger is a pair of pliers ground to fit a marble in the pouch.
I had to a length just to full draw a pair of silver Thera Band rubbers.
I made the pulleys out of static caster wheels held and spinning against a bench grinder wheel.
A triangle that flips down to hold the right angle is definitely needed.
Perhaps another automatic hold-back.
I may have to go to a multi-pulley system to draw this giant.
I added a few photos to show some details.
The pulley draw really helps and I can tie it off to prevent swing up.
