Making a Marking gauge

摘要

Marking gauges are familiar items to woodworkers and they are used to scribe lines parallel to the edge of the work piece. Typically, they are used to mark out tenons. Similar gauges are not so common for marking metal. Metal workers tend to use |enny callipers (also known as odd leg callipers) or a scribing block to mark lines parallel to the edge of a piece being worked on.
