A sliding bevel is a tool used typically in woodworking to replicate or transfer existing angles onto wood that are not 90 degrees. The device can also be useful for checking angles. Some other ways a sliding bevel may be utilized are for marking angles onto roof rafters, laying out a dovetail and finding the angles of corners where two walls meet.
A sliding bevel consists of a blade, tightening screw/nut mechanism and a stock. The stock is made of wood, while the blade is steel metal. The blade can be set to any angle measurement from 0 to 180 degrees.
To use this woodworking tool, the stock is placed against the edge of a wood piece and the blade should be across this piece. The tightening screw should be loosened to set the desired angle. This angle is locked into position by retightening the screw. Once this angle is set, a marking tool is used to draw a line and mark this angle on the wood. The wood piece is then cut at this marked angle with a cutting tool.
A sliding bevel can have different names, such as an angle bevel or sliding T bevel. The blade on this device is always longer than the stock. Although the stock is usually made of wood, it can be also plastic or metal.
