A temporary hammer

Fig. 1

One tool which you will need in making almost all the other tools mentioned in the following pages is a hammer. If you can borrow one or a suitable substitute for a day or so, you can move on to the next section. If not, you can make a temporary hammer quickly.

You will need the following materials:

One large nut and bolt to the dimensions shown

One piece of wood, such as a thick branch of a tree Length: Not less than 35 cm (cm = centimeter) Circumference: Between 21 cm and 23 cm

One nail, 7/½ cm long
Three nails, 5 cm long

Fig. 2

To measure the circumference of the wood, wrap a piece of string around the wood as shown and mark the string. The measure the distance between the marks. This distance should be between 21 cm and 23 cm.

Fig. 3

With a large knife, slice the piece of wood down the middle to a distance of 16 centimeters. Force the bolt into the slit and down four centimeters from the top. Place the nut on the bolt.

To keep the bolt in place and the wood from splitting further, you will need to hammer a few nails as shown in the diagram. A heavy stone can be used to drive in the nails.
