Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Function and type of striking mechanism includes one (1) or more of the following:

motive force (mainspring or weight driven)

gear train (transmits power)

ways of producing striking sound (metal gongs, chime rods, bells or air bellows)

count wheel striking movements (European or American manufacture)

rack striking movements (European or American manufacture)

Record and document repair process includes one (1) or more of the following:

date and extent of repair

cost of replacement parts

time spent on procedure

Operation of strike mechanism includes one (1) or more of the following:

hour struck corresponds with hands

release mechanism synchronised with hands

warning set-up correctly

function of release mechanism

sound generation (gongs, rods or hammer engagement)

Striking mechanism components include one (1) or more of the following:

release mechanism

gathering pallet

detents

counting mechanism (snail or count wheel)

rack

gongs, chime rods and bells

hammers

Faults in striking mechanismcomponents include one (1) or more of the following:

incorrect striking

continuous striking

striking mechanism stops clock or impacts on timekeeping

warning set-up

gong security

pin security

gathering pallet engagement with rack teeth, tightness and positioning

rack tail engagement position with snail

hammer inserts (condition - worn or aged)

security of gongs, rods and attachment to case

Correct set-up includes one (1) or more of the following:

synchronised strike release with hands

amount of warning

correct sequence

sound of strike

Lubricants to striking mechanismcomponents include the following:

correct lubricants for cams and detents

techniques for lubricating

Hand and bench tools and equipmentincludes one (1) or more of the following:

clock repairers' hand tools:

tweezers

screwdrivers

eyeglasses

universal shifter, sockets and spanners

pliers, end cutters and files

stakes for supporting removal or replacement of gathering pallet and cannon pinions

oilers and oil pots and greases

cleaning brushes, peg wood, solutions, rinses and solvents

Appropriate working environment includes the following:

clean bench and working area

adequate lighting and ventilation

tools and equipment organised and in good condition

ergonomic seating, including bench height

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
