Bevel Gauge
The bevel gauge is a measuring tool that
has an adjustable sliding blade. The blade is adjusted to
the dimensions of a desired angle and then it is locked
in so that the exact measurement of the angle is able to
be marked on a separate piece. The bevel gauge is also referred
to as an angle bevel, sliding bevel, bevel square, sliding
T-bevel, or adjustable try square.
The bevel gauge consists of a tongue (blade)
that fits into a groove cut into the head of the stock (handle).
Tongues vary in size, usually from seven inches to eighteen
inches or more. The stock is always shorter than the length
of the blade. The head of the stock contains a groove which
fits the tongue of the bevel gauge. Most models allow for
adjustments on the position of the tongue and the stock.
When using a bevel gauge, you want to make
sure that the tongue is stretched against the piece you
are working with and that the stock is held up against an
edge. The tongue is then adjusted to the desired angle,
anywhere between 0 and 180 degrees. Once the angle is selected,
you will want to lock the angle in position by tightening
the bolt and wing nut or lever device. Due to this locking
device, the bevel gauge is great for matching existing angles.
