Another wood holder

Fig. 33

Four wood holders are usually needed to hold a piece of wood vertically for sawing. See Diagram B on page 25.

To make the wood holders you will need the following materials:

Four pieces of wood Length: more than 8 cm but less than 10 cm Circumference: If a string is put around the wood and marked, the marks on the string should be between 6 and 8 cm apart

Four nails, 5 cm long

Hammer

Saw

Drill

Bench Hook

Making a Wood Holder

Use a drill to make a hole in the center of a piece of wood. Choose a drill which will make a hole that is slightly smaller than the nail that will fit into it. Drill the hole almost through the other side of the wood. Diagram A shows the wood supported by a bench hook while being drilled. Then hammer the nail through the hole until the head of the nail reaches the wood. The best place to do this is on soft ground from which the nail, attached now to the wood, can easily be removed.

Diagram A

Four of these wood holders can be used to hold what you are sawing securely against a log or large piece of wood as shown.
