Permanent hammer with wood handle

If bamboo is not available in your area, you can make a permanent hammer using a thick branch from a tree.

You will need the following materials:

One piece of wood, 30 cm long and 12 to 16 cm around one large nut and bolt

Chisel

Temporary hammer

Heavy knife

Making the Hammer

With a heavy knife, such as a panga or machete, shape the lower part of the branch so that it has the form shown in the following diagram.

Fig. 28

Mark off the area at the thick end of the handle where the bolt will go. With a chisel and a hammer, cut through the wood inside the pencil mark until you have made a hole completely through the thickness of the wood. Remember to cut away small pieces at a time. When you think the hole looks big enough, try forcing the bolt through. If it does not fit, keep cutting with the chisel until it does. Try to cut the hole so that the bolt will fit tightly. Finally, push ii the bolt through, and place the nut tightly on the end of the bolt. A nail remover can also be added to this type of hammer (See Section F).
