Squares

Squares are essential layout and checking tools used in woodworking to mark and verify angles, especially 90° (right angles) and 45° angles. They help ensure accuracy in joinery, assembly, and cutting.


Common Types

  • Try Square Fixed 90° tool with a blade and stock. Used for marking and checking right angles.
  • Combination Square Adjustable head on a ruler. Commonly used for 90° and 45° marking, depth measurements, and layout work.
  • Engineer’s Square All-metal precision square for high-accuracy checking.
  • Speed / Rafter Square A triangular, multi-purpose square used for quick marking of 90° and 45° angles, as well as for measuring and laying out common angles in framing work.
  • Framing Square Large L-shaped square for layout of bigger workpieces and construction tasks

Uses

  • Marking 90° and 45° lines
  • Checking squareness of edges and joints
  • Guiding saw cuts
  • Laying out joinery

Sliding Bevel (Bevel Gauge)


A sliding bevel is an adjustable tool used to transfer and mark angles that are not fixed (unlike squares).

  • Consists of a handle and a movable blade locked with a screw
  • Can copy angles from a workpiece or drawing
  • Commonly used for miters, dovetails, and irregular angles
  • Does not measure angles directly, but transfers them accurately

Care

  • Avoid dropping or bending
  • Check accuracy periodically
  • Keep clean and dry to prevent rust
