I'm sorry about the dark pictures.
Yellow and flash do not make a clear pic.
About this creation
WARNING: This is a high compacity rubberband pistol and should not be overloaded. The max. compacity recomended is 20 although it can go up to 30. Overloading it may cause serious damage to your pieces or be dangerous to you. I cannot be held responsible for your actions so build my guns at your own risk.
Now take about 20 rubberbands.
And put them onto the gear. You can put 3 on at a time.
To load more wind the star piece backwards.
Just as a warning after about 20 rubberbands or so are loaded, the barrel might bend back a little.
