1. Calculate the percentage moisture content of a piece of timber which weighed 715 g when wet and 550 g when dry.

1. List four upholstery tools.
1. List two wood turning tools.

Most candidates were able to:

-           name the labelled parts;
-           state the methods of bending wood;
-           list the upholstery tools.

However, they were unable to list wood turning tools.

The expected response to question 4 is as given below:

T          -           haunch
U         -           tenon
V          -           shoulder

(b)       -           Kerfing, lamination

(c)        Percentage moisture content =

Wet weight – Dry weight  x 100
Dry weight                  1

-           Correct substitution
715 – 550 x 100 = 165 x 100
550            1      550     1

=          30%
