A jig used in making jewelry, a specific type of jig, is a plate or open frame for holding work and helping to shape jewelry components made out of wire or small sheets of metal. A jig in the jewelry making application is used to help establish a pattern for use in shaping the wire or sheets of metal.
circumventing jigs altogether. Franklin D. Jones, in his textbook Machine Shop Training Course (5th ed), [4] noted: "In many cases, a jig borer is a 'jig eliminator.' In other words, such a machine may be used instead of a jig either when the quantity of work is not large enough to warrant making a jig or when there is insufficient time for jig ...
Jigsaws with sole plates that have a beveling function can cut angles typically up to 45 degrees relative to the normal vertical stroke to make miter joints. Portable jigsaws have historically been mains-powered, but are increasingly being displaced by battery-powered models.
A helping hand, also known as a third hand, soldering hand, or X-tra Hands, is a type of extremely adjustable jig used in soldering and craftwork to hold materials near each other so that the user can work on them.
A drill bushing, also known as a jig bushing, [1] is a tool used in metalworking jigs to guide cutting tools, most commonly drill bits. Other tools that are commonly used in a drill bushing include counterbores, countersinks, and reamers. They are designed to guide, position, and support the cutting tool. [2]
The jig borer popularized the ideas of coordinate dimensioning (dimensioning of all locations on the part from a single reference point); working routinely in "tenths" (ten-thousandths of an inch, 0.0001") as an everyday machine capability; and using the control to go straight from drawing to part, circumventing jig-making. In 1920 the new ...

A jig grinder is a machine tool used for grinding complex shapes and holes where the highest degrees of accuracy and finish are required. The jig grinder is very similar to a jig borer, in that the table positioning and spindles are very accurate (far more so than a manual milling machine or lathe). It is used almost exclusively by tool and die ...
