A T-bevel, also referred to as a sliding T-bevel, is a useful tool for transferring angles for woodworking and metalworking. The tool consists of a handle, which is often made of wood, but may be plastic or metal, and a blade, which is typically medium gauge steel. The blade is loosely screwed to the handle; a locking lever or wingnut tightens the blade in place once it has been set to the desired angle. Some T-bevels employ a locking nut at the base of the handle.
Slide the blade of the T-bevel out to its furthest position, so the tool resembles an "L" rather than a "T".
Set the angle on the T-bevel. If using a protractor, place the handle against the base of the protractor, with the edge of the blade passing through both the origin and the desired angle on the protractor. If transferring an angle off an existing work piece, place the handle against one face of the piece, and the blade against the other. Lock the blade in place using the lever or wingnut.
Adjust the angle on the mitre saw. Lock the blade of the mitre saw in the down position. With the handle of the T-bevel against the mitre saw's fence, rotate the saw's table until the saw blade fully contacts the blade of the T-bevel. Lock the saw table in place.
- It is easy to knock the blade out of alignment when transferring an angle; always double-check your measurements.
- Wear eye protection when using power tools.
- For maximum safety, unplug the mitre saw before making any adjustments.
