Definition: A jig is a specialized tool used to hold, support, or guide materials in a precise position during production, assembly, or fabrication processes. In picture framing, jigs are commonly used to ensure accurate cuts, consistent joinery, and repeatable placement of hardware or components.

Characteristics

Precision Alignment: Keeps components in the correct orientation and alignment during cutting, drilling, or assembly.
Repeatability: Allows for consistent results across multiple frame pieces or joints.
Versatility: Can be used for mitre cuts, drilling holes for hardware, or guiding specialized joinery techniques like dovetail keys or spline joints.
Material Support: Provides stable support for workpieces, reducing the risk of movement or errors.

Uses

Miter Cutting: Guides saws or cutting tools to create accurate 45� or 90� cuts for frame rails.
Hardware Placement: Assists in drilling pilot holes or positioning screws, D-rings, and other mounting hardware precisely.
Joinery: Ensures proper alignment when using techniques like finger joints, lap joints, or dovetail key joinery.
Production Efficiency: Speeds up repetitive assembly tasks while maintaining accuracy, critical in professional framing shops.

Best Practices

Choose the Right Jig: Use a jig specifically designed for the task to avoid misalignment or damage to frame components.
Secure Workpieces: Clamp or fasten materials properly to prevent slippage during cutting or drilling.
Inspect Regularly: Check jigs for wear or damage to ensure continued accuracy and safety.
Maintain Clean Surfaces: Remove sawdust, adhesive residue, or debris to avoid interference with precise alignment.
