A muzzle brake which may be integrally formed on the end of a gun barrel or it may be an adapter which is threadably attached to substantially the end of any gun barrel of choice. The muzzle is integrally formed and includes a first interior bore which is attachable to a gun barrel and a second interior bore which is of a size and shape to slidably receive a bullet therethrough, with the muzzle brake having multiple vent ports which are so designed as to direct exiting propellant gasses in a manner that will urge the brake and gun in a forward direction, so as to reduce recoil and also simutaneously urges the brake and the gun downward, so as to reduce vertical lift.

An apparatus for forming serrated edges in wooden panels for interengagement with abutting panels in a wooden I-beam assembly comprises opposed sets of broaches operable for cutting a toothed serration pattern cleanly and accurately in opposed edges of a stack of up to 40 such panels simultaneously. The panels are loaded in infeed means of the apparatus which transports the stack into position for broaching. The stack of panels is aligned laterally by lateral stack alignment means upon placement of the panels in the infeed means. Longitudinal stack alignment means aligns the stack longitudinally when it is transported by the infeed means to a position for broaching. During broaching the stack is supported on opposed anvils in a manner for forming the serrations symmetrically with respect to each end of the stack, hold down means clamps the stack on the anvils, and actuation means drives the broaches downwardly.
