A cylinder block fixture for securing a workpiece is disclosed. The cylinder block fixture includes a base and clamping members. The clamping members are positioned apart at a distance facing each other on the base. Each of the clamping members includes a support plate at one end and a hand wheel at another end. Each of the support plates comprises a shaft, support bars, and support rods facing the opposite clamping member. The support rods extend from the support bars. The shafts at the support plates receive a camshaft housing of a workpiece. The workpiece includes a cylinder block. The support rods secure the workpiece. The hand wheel rotates and causes the workpiece to rotate. The workpiece rotates to align and take reference from a main bore or a pan rail surface of the workpiece to perform machining operations on the workpiece.

Present invention teaches a two-in-one angle clamp where individual angle clamps can be moved and locked to a desired angle on a base plate to work with work pieces set at an desired angle to each other, with supporting magnet rest pieces to provide horizontal support at a height that's either matching the thickness of the base plate or the combined thickness of the base plate and the clamping head.

The system includes a forward clamping assembly, steady rests and compression assembly upon which the fuselage of a rocket is secured. The forward clamping assembly secures the forward fuselage of the rocket and the steady rests secure the middle fuselage of the rocket. The compression assembly includes a fluted nozzle rotator which engages the flutes of the nozzle of the rocket. Rotation of the nozzle rotator results in torque being applied to the joint connecting the rocket nozzle with the motor casing of the rocket so as to allow insertion or removal of an Ortman key that secures the motor casing and nozzle.

Vise jaws are provided with base plates having bolt receiving holes or slots passing therethrough near top edges thereof. Soft jaws formed of a readily machinable material are provided with threaded bores which can receive bolts passing through the holes or slots in the base plates, the bolts also pass into the threaded bores to hold the soft jaws to the base plates. The soft jaws can be provided with a modified contour to match a geometry of a workpiece to be held. A locating pin can cooperate with alignment holes and alignment bores in the base plates and soft jaws for precise alignment of the base plates and soft jaws together. Adapters are also provided which can attach to surfaces of base plates and be rotated to present edges at a variety of different angles for supporting of workpieces in various angled orientations.
