2.  Measurement started with items common to man such as a hand length, an arms length, the length of a foot or many other common items. These proved to be inadequate.

3.  Is a metal ruler  Used for accurate measurements  Can be used as guides for laying out lines  Rigid steel rules can be used when cutting straight lines.

4.  A straight edge ruler and a beam or stock piece that are joined together at a 90˚ angle  Used for layout lines perpendicular to an edge/side Check that a board is square Check a board’s flatness  If a try square is dropped it may become inaccurate (not square.

5.  Consists of: Blade – steel rule Square head Center head Protractor head  Used like a try square  Layout angles  Find the center of round stock (center head)  Measure the depth of a hole

6.  Used to measure boards Testing corners Laying out various angles  2 measuring blades are set at 90˚  This tool can be inaccurate if dropped…but can be reset.

7.  The blade on the T- Bevel is movable  It can be set at any angle between 0˚ and 180˚  The locking screw secures the blade in place.  You can use various other tools to set the angle and then test your pieces to see if the angle matches.

8.  Accurately measure and mark long distances  Transfer arcs and circles

9.  Tools used to draw arcs and circles  One point stays stationary (point), while the other end draws the arc (pencil)

10.  Used to smooth arcs or making the transition from an arc to a straight line  Layout curves and other designs

11.  A flexible form of a ruler (metal strip)  Self-retracting coiled measuring tool  Tip moves slightly to allow for accurate inside or outside measurements

12.  Allows you to draw a straight line over a long distance.  String and chalk is contained in the body of the tool  You pull the line tight and snap it. The result is a chalk line.

13.  Find an uncommon tool used in the woodworking shop.  Create 2 posters for the tool: 1. Create a fake name and use for the tool 2. Indicate the real name and use for the tool.
