Thread: Cannon

Hi i have built a few and now have them running on a electronic dump valve and shuttle valve [ so just a push button fire ]
was first designed to rope a tree .. @ 70 psi it will lift 75m of 4mm para cord straight up including the pull slug ..
golf balls just go a shit more in height hahaa but when they return will bury themselves 2 inches below the ground level [hard to find like that ]
The latest design used a camlock to fit the barrel of which different sizes can be attached .. So you could call them a take down model ..
