The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Evidence:
|
Hammer, tension and back-gauge saw
|
|
Ridges or lumps across and along saw are assessed and matched on both sides of the blade Completed |
Evidence:
|

Evidence:
|
Ridges or lumps are progressively removed through hammering and the use of structure rolls or levelling rolls to achieve flatness Completed |
Evidence:
|
Hammering or rolling patterns are controlled to localise stresses to avoid spring-back and re-occurrence of defects Completed |
Evidence:
|
Saw is checked against required curvature using a gauge to identify tensioning requirements Completed |
Evidence:
|
Tension curvature is obtained across and along saw in line with required standard Completed |
Evidence:

Evidence:
|
Worn, broken or ground surface is prepared for metal build up or replacement by applying heat and pressure Completed |
Evidence:
|
Teeth are built up or replaced using compatible welding material and welding procedures that ensure specified metal penetration and density Completed |
Evidence:
|
Weld run-off tabs are used to limit stress and hollows at edges of the saw Completed |
Evidence:
|
Teeth are ground or filed to required shape, tolerance and pitch Completed |
Evidence:
