Pocket hole jigs allow the user to drill a hole at an accurate angle to get a good joint. Using a pocket hole jig also makes for a cleaner and neater appearance as opposed to creating a pocket hole without the help of a jig. [ 2 ]
Concealed hinge drilling jig with embedded Forstner bit. A concealed hinge drilling jig is a type of support jig, designed for drilling 3 cm holes to fit concealed hinges into modern wardrobe doors. As many of the complementary tools used in woodworking, it uses an electric hand-drill for its operation, making a Forstner bit to turn.
An example of a jig is when a key is duplicated; the original is used as a jig so the new key can have the same path as the old one. Since the advent of automation and computer numerical controlled (CNC) machines, jigs are often not required because the tool path is digitally programmed and stored in memory. Jigs may be made for reforming plastics.
The jig borer was a logical extension of manual machine tool technology that began to incorporate some then-novel concepts that would become routine with NC and CNC control, such as: coordinate dimensioning (dimensioning of all locations on the part from a single reference point);
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 ...
A fish-jighead hook. The weighted "head" of a jig, or jighead, can consist of many different shapes and colors along with different features. [2] The simplest and most common is a round head, but others include fish head-shaped, coned-shaped, cylinder-shaped and hybrid varieties that resemble spoons or spinnerbaits.
Ancient Egyptian woodworking. There is significant evidence of advanced woodworking in ancient Egypt. [1] Woodworking is depicted in many extant ancient Egyptian drawings, and a considerable amount of ancient Egyptian furniture (such as stools, chairs, tables, beds, chests) have been preserved.
Jig concentrators are devices used mainly in the mining industry for mineral processing, to separate particles within the ore body, based on their specific gravity (relative density). [1] The particles would usually be of a similar size, often crushed and screened prior to being fed over the jig bed. There are many variations in design; however ...
