March 2

  • Today we made a start on our drawing boards that we made yesterday. Then we took our small tables to the Circular Saw which we got to use to cut the sides of our timber to the length or width size we wanted it to be. Before we used the circular saw we were taught and shown the safety rules on how to operate the machine: never stand directly behind the blade when cutting timber or else the timber will kick back and fly straight towards you, wear your ear muffs and safety glasses/goggles at all times when operating it or if in the same area its being operated in. While i was cutting my own timber i found it easy to operate it because we didn't need to focus on trying to cut a straight line because the machine has a bar on it were you can lean the timber against it and just push the bar keeping the timber stabled and producing a clean and straight cut.



  • Then after that we took our timber to the Thickness er machine which planed the surface of the wood leaving a clean and smooth surface. There were not that much safety tips but what i did learn was to always turn the dust extractor on before starting the machine and to wear your ear muffs at all times. Then i measured the size of the handle and used the Hand Drill to drill a hole in the handle i found it difficult as i drilled the first hole because we were told a certain way of drilling the hole and prevent chipping it on the other side but instead of asking i thought i could do it on my own so i did and ended up chipping it a little then i asked someone who knew and then tried it myself and felt proud to know that i did it the correct way without chipping it. i learnt some thing new and then used the Saber Saw and started sawing along the lines from the holes i drilled. But before i started using any of the machines/power tools i followed the safety procedures and wore my safety glasses/goggles and ear muffs and while i was using the saber saw i found it challenging to stay focus on cutting the line and not moving off it but i enjoyed it in the end. I was also taught to never put your fingers near the blade or when using the drill to NOT wear loose clothing and to always wait to the power tool or machine finishes operating before putting it down or before leaving it out of your sight.

  • Then i started sanding the edges and corners of the handle making it straight. After that i moved onto the Router machine which its purpose was to cut a long line just below the handle for pencils or pens to sit in. There were multiple pieces of wood clamped to the table to secure our drawing tables in place as we cut a straight line across the surface at a 3/4 depth. We operated the machine while using ear muffs and safety goggles/glasses and as we operated it we also put the wire over our shoulder to prevent the blade of the router cutting the wire off. In class we did some more maths and learnt how to calculated decimal points with percents and GST. eg.15%= 15 divided by 100= 0.15 
  • then add 15%(0.15) to 200
  • instead i wrote in the calculator 0.15 times 200=30. when its suppose to be 1.15 times 200
  • then the real answer would be 230
