Jigs Devices that hold and move a work-piece in relation to a tool. Often they are designed as carriages that slide. Jigs act as a guide for the tools that cut and shape the wood, and they are ideal for repetitive tasks.
Fixtures Stationary devices that hold the wood in a set position in relation to a tool. Some of the more typical examples of fixtures are fences -- such as a ripping fence on the table saw.
