_____________________________________________________________________________________________________
Observation
  1. State two methods of bending wood.
  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:

(a)       S          -           aris edge side/face/edge
            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%

 

(d)       -           staple gun
            -           scissors

            -           pair of compasses
            -           pair of dividers
            -           rule
            -           pencil
            -           trysquare
            -           parting tool
            -           round nose chisel
            -           spear point chisel
