how to use basic tools
hammer & screwdriver

hammer
A medium weight (12-13 ounce) claw hammer is good for general purposes.

• Hold a hammer near the end of the handle for more hitting power.
  
  
• To start a nail, hold it in place & tap it gently a few times until it is firmly set. Hit it straight in (Fig. 1)
  
  
• To avoid hammer marks on the wood, use a nail set or another nail to drive a nail the last one-eighth inch into the wood (Fig. 2)
  
  
• To remove a nail use the claw end of the hammer. Place a small block of wood under the head of the hammer to avoid marking the wood (Fig. 3)

screwdriver

You need two types of screwdrivers for household repairs: Straight blade (Fig. 4) & Phillips (Fig. 5)

Both come in various sizes. The blade of the screwdriver should fit the slot in the screw (Fig. 6)

When using the screwdriver, push against the head of the screw as you turn it (Fig. 7)

It's easier to put a screw into wood if you make a hole first w/ a nail or drill (Fig. 8). Rub wax or soap on the screw threads to make it go in easier.
