Gauges are mainly used in designing and making to measure, mark or transfer distances.
Features and Applications
|Marking Gauge||Used to scribe lines parallel to the Face Edge or Face Side of timber or similar materials (i.e. used in much the same way that Oddlegs are used by metalworkers).|
|Cutting Gauge||The small cutting blade is used instead of the normal spur of a Marking Gauge when lines have to be scribed across the Grain (e.g. when marking out a shoulder for a Housing Joint)|
|Pencil Gauge||Sometimes scribing a line into the surface would be detrimental to the finished product and so, although less accurate, a pencil can be used instead of either a spur or a blade (e.g. when marking a bevel or chamfer)|
|Mortise Gauge (aka Mortice Gauge)||These are similar to a Marking Gauge but have two spurs which are set a distance apart equal to the Mortise Chisel to be used when marking out for a Mortise and Tenon Joint for example.|
|Bevel Gauge (aka Bevel Square or Sliding Bevel)||These are used to copy or mark angles other than the more common 90 degrees or 45 degrees.|
