                                       All VEX parts (except
                                        the joystick) use two
                                            sizes of hex keys
                                                (3/32 & 5/64).
                                          Each robot kit has
                                             two hex keys.
                                       These hex wrenches
                                                are better.

           Hex
         Wrenches

• Ball-end hex drivers can be used to at an angle.
• T-handle hex wrenches give you more torque.

          Competition Switch




• Use for scrimmages in the classroom.
• Up to 4 robots can be enabled/disabled and set
  to autonomous operation or driver control.

                  Pliers




                          needle-nose

             Use pliers to grasp, hold, and bend.
             Using pliers to turn nuts or screws will scratch nuts and
             damage the threads on screws.
             Remove stripped screws by grasping their heads and
             turning with a pair of pliers.

                                     Vise

  • Use to bend or hold
    metal.
  • Jaws can crush things.
  • Clamp to a heavy table
    or bench.
  • Do not clamp to a
    student desk!


The vise won’t fit in the toolbox.          J.M. Gabrielse
         Ball-Peen Hammer




Put metal in the vise and hit with
the hammer to bend it.

          Safety Glasses




• You must wear safety glasses when
  working with metal.
• So must everyone else nearby.

                 Bending Metal
• Mark (with a marker) where you want the metal
  to bend
• Secure in a vise so the jaw closes just below the
  bend-mark.
• Tap with the hammer until the metal bends at
  the desired angle.

               Hacksaw

• Measure (count holes or use a ruler)
• Mark (use markers on metal)
• Remeasure: “measure twice, cut once”
• Secure in a vise
• Place hacksaw on mark and pull
  backwards several times to start a groove
• Pull back & forth to cut
