Apparatus and methods for impact tool testing

A torque testing device includes a body defining an interior volume that is defined by an interior wall having a non-circular cross-section. A moveable portion is within the interior volume and is selectively movable from a first orientation within the interior volume to a second orientation within the interior volume. The moveable portion includes a core defining an aperture and a piston. A portion of the piston cooperates with the aperture of the core. When the moveable portion is in the first orientation, the piston is located at a first distance from the core. When the moveable portion is in the second orientation, the piston is located at a second distance from the core, the second distance being less than the first distance.
