A sliding bevel, also called a T-bevel, is used to lay out and transfer angles. Its movable blade adjusts relative to the handle.
Parts and controls
- A sliding bevel has a handle, a blade and a locking adjustment. Designs may use a thumbscrew or wing nut; check access to the lock on the chosen tool.
Copying an angle
- A generic sliding bevel allows the blade and handle to be set against an existing angle and locked for transfer to another surface. The tool preserves the chosen setting while locked.
Angle values
- A protractor can be used to set a sliding bevel to a specified angle. Copying an angle and reading its numerical value are different tasks.
Scope and limits
- Choose a fixed square for a fixed right-angle reference and a sliding bevel for adjustable angle transfer. This overview does not establish the accuracy of an individual tool.
