Tips for gathering evidence to demonstrate your skills

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!

Level, tension and back-gauge saw blade

  1. Assess and match ridges or lumps across and along saw on both sides of blade.
  2. Use gauges and straight edges in both directions to test blade accuracy.
  3. Remove ridges or lumps progressively through levelling and use stretcher or levelling rolls to flatten.
  4. Localise stresses using controlled levelling or rolling patterns to avoid spring-back and re-occurrence of defects.
  5. Check saw blade against required curvature using a gauge to identify tensioning requirements.
  6. Obtain tension curvature across and along saw blade.
  7. Check alignment of saw back against tolerances using a gauge; roll non-conforming areas to obtain required tolerance.
