Mini Projectile Launcher

This simple but precise launcher projects 16 mm steel balls at ranges suitable for use on the bench top or from the bench to the floor. A protractor and plumb line make it easy to set any required launch angle from 45° downwards to straight up. Three different spring tensions give three repeatable launch speeds (ranges of 1m, 1.5m and 2m) and a magnetic piston ensures that the ball does not touch the side of the barrel and launches straight every time. A cable release gives a smooth triggering to prevent jerking. The unit can stand on its own or be fixed to the bench with a clamp.
