We finished the occupational health and safety test this morning and that pretty much wraps up this block. It was all about fire safety, houskeeping on site and what to do if an injury happens at with with you or a work mate.

today we had another written test on calculation which everyone passed. We had to work out how much material we required to fix out a house by looking at the plan, and the cost of these items. This included skirting, architrave, nosings and scotia.Then we went through another booklet on health and safety for carpenters. it went through types of fire extinguishers, hazards and precautions that should be taken when on site.

Today we spent the morning revising notes on claddings and linings until smoko, then had the test before lunch. After lunch we did bookwork revising on the test tommorow on fixing out until the end of the day...

Today we spent the first half of the day on the computer doing assessment questions, working out how much cladding we would need by looking at a few house plans then totalling the cost. There is a methodical way to working this out that isnt hard if you follow the steps. then we had time to just get our blogs up to date.

In the second half of the day, we were down in the workshop while some people finished hanging doors. There wasnt really much i could could do so i just made a cutting -board using strips of jarrah and pine glued together,then ran through the thicknesser until it was smooth.
