Abstract
A spring hammer for rapping a surface, the spring hammer includes an anvil with an impact surface. The anvil can fastened to the surface to be rapped. A movable piston has a first end that is in operation moved towards the impact surface of the anvil. A guiding structure guides the piston to move in a defined direction with respect the anvil and a device for launching the piston to move the piston towards the impact surface of the anvil. The piston is a solid block in which the first end of the piston is machined to an integrated flexible spring geometry.
