Using A Marking Gauge

Used for scribing accurate lines in wood, the stock of the marking gauge must be firmly held against the datum face. Control of the depth of cut depends on tilting the stock so that the forward corner of the stem rests on the surface of the job, a deeper scribe should fallow a light cut. The marking gauge should be held with the thumb as near to the point as possible, the index finger over the curve of the stock and lateral pressure applied by the middle finger.

While holding in the proper fashion, first set the gauge then make final adjustments by tapping one end or the other on the bench top. When the stock is too tight to jump it makes a dull thud, whereas when set just right, it makes a clicking sound. Start the stroke with the lower end of the work resting on a firm surface. Tilt the subject so that the stock can clear the end, the gauge might catch on the working surface otherwise. Try to make one fluid stroke for the best results. To limit the length of a gauged line, scribe the points where the line should end and you will be able to feel when the gauge drops into the mark.
