Tape Measures

• Used for
  • Measuring
  • Divisions

Try Square

• Three purposes
  • Layout lines across grain of wood.
  • Test edge or end for squareness.
  • Test work for uniform width or thickness.

This is not a hammer!

Combination Square

• Used for
  • Measuring
  • Measuring and marking 90 and 45 degree angles.
  • Marking gage.
  • Level.

Speed Square

• Layout lines across grain

of wood.

• Measuring
• Laying out rafter angles.
• Laying out angles.

Sliding T-Bevel Square

• Main Use
  • Transferring angles to radial arm saw, compound miter saw, other tools, or from one board to another.

Folding Rule or Zig Zag Rule

• Use for
  • Measuring
  • Can be used to measure spans over head.
  • Not the most accurate tool.
