GOALS FOR SUCCESSFUL COMPLETION
Theory:57
i)
Given drawings/photographs of
60 contemporary and traditional fasteners and associated tools used for making
timber connections, learners will identify the correct names and uses of each
within 30 minutes and score a minimum of 70%, or 42 correct answers. 58
ii)
Given a multiple choice test of
30 recall/recognition type questions about the properties, capacities and
applications of various timber fasteners, the learner will answer all questions
within 30 minutes and score a minimum of 70%, or 21 correct answers. 59
Practical:60
iii)
Learners will safely and
correctly select, layout, prepare, apply and remove a variety of fasteners to
timbers. These will include the following: 61

off-set 63
c.
Bolts and washers, to specified
torque 64
d.
Split Ring Connector 65
e.
Shear Plate Connector 66
iv)
Given clear drawings and
general specifications of 10 different timber connections, learners will
identify an appropriate fastener and determine the following: 67
a.
Correct method of application 68
b.
Appropriate application tools 69
c.
