The American Forge & Foundry 6" Heavy-Duty Automotive Swivel Vise (3948) is an essential tool for any workshop, providing exceptional stability and versatility for a wide array of tasks. Crafted from high-quality Class 30 iron castings, this vise boasts an impressive 30,000 lbs. of tensile strength, ensuring it can withstand rigorous use and provide a secure grip for demanding applications. Whether you are engaged in woodworking, sawing, drilling, or precision metalwork, the 3948 vise offers the robust foundation you need. Its thoughtful design incorporates features that enhance both functionality and longevity, including a fully enclosed spindle and permanently lubricated chamber to protect against contaminants. This vise is not just a clamping device; it’s a reliable partner for shaping, forming, and securing your projects with confidence.

KEY FEATURES AND BENEFITS:

• Exceptional Clamping Force: Built with Class 30 iron castings, providing 30,000 lbs. of tensile strength, ensuring a very strong and secure hold for heavy-duty workpieces.
• Versatile Positioning: The 360° swivel base, equipped with dual lock-down handles, allows users to precisely rotate and secure their workpiece from any desired angle, optimizing access and workflow.
• Long-Lasting Grip: Features precision-machined, hardened steel jaws that offer a superior, non-slip grip. These jaws are also replaceable, extending the lifespan and utility of the vise over many years of use.
• Integrated Metal Shaping Capability: Includes a large, machine-ground anvil work surface, ideal for cold forming, bending, and shaping various metal components directly on the vise.
• Secure Pipe Clamping: Built-in pipe jaws provide a dedicated and secure grip for round objects, accommodating pipes and rods up to 5 inches in diameter, adding to the vise's versatility.
• Protection Against Contaminants: The fully enclosed spindle, slide, and screw design prevents the ingress of dust, grit, and debris, significantly prolonging the lifespan of internal components.
• Maintenance-Free Operation: A permanently sealed and lubricated chamber ensures smooth operation for years without the need for additional lubrication, reducing maintenance requirements.

HOW TO USE:

• Mounting the Vise: Securely bolt the vise to a sturdy workbench using appropriate hardware. Ensure the mounting surface can support the weight of the vise and the forces applied during use. Position it to allow full 360-degree rotation if needed.
• Adjusting the Swivel Base: If rotation is required, loosen the dual lock-down handles on the swivel base. Rotate the vise to the desired angle. Once positioned, firmly tighten both lock-down handles to ensure the vise is securely anchored and will not shift during work.
• Clamping a Workpiece (Flat/Square): Turn the main handle counter-clockwise to open the vise jaws to an opening slightly wider than your workpiece. Place the workpiece between the hardened steel jaws. Turn the main handle clockwise to close the jaws and apply firm, even pressure until the workpiece is securely held without slipping.
• Clamping a Workpiece (Round/Pipe): For pipes or round stock, open the main jaws sufficiently to expose the built-in pipe jaws. Place the round object into the dedicated pipe jaws. Turn the main handle clockwise to tighten, ensuring the pipe jaws grip the object firmly and prevent rotation.
• Using the Anvil: For shaping or forming metal, place the material onto the machine-ground anvil surface. Use a hammer or other appropriate tools to strike and shape the material against the anvil, leveraging its flat, hardened surface for support.
• Releasing the Workpiece: After completing your task, turn the main handle counter-clockwise to open the jaws and carefully remove the workpiece. Ensure the vise jaws are clear before proceeding to the next task.
