15082011(chiselling)

We made handles by using bench saw on the 2nd floor on the last Wednesday. That was the only practical job that we have done. In the morning class, we learned the mechanical system inside the thicknesser, because someone adjusted the height of the rollers inside it. They have to be the same height of the bottom surface.
A student who was contaminated by epoxy two weeks ago popped by in the class for doing something, and Chris told us about human mechanism showing pre-sign by our immune system when someone is contaminated of something and he told that skin is our biggest organ, which sounds like true(it is true and the second one is a liver weighing 1.5kg while the former one is 3kg).
- do not measure at the end of timbers or planks especially after using thicknesser, because sometimes they are stepped.
- flat band sander
- dust is explosive, definetely saw dust as well.
- do not feed in the planks twice into the thicknesser, unless it is adjusted twice.
- microswitch on the flat band sander to measuer the exact thickness of woods
- emergency stop button
- vacuum system with the rubber conveyor belt on the flat band sander helps thinner timbers make flat when we feed them in as well as it extracts the saw dust from them.
- chiselling

The biggest part of what I experienced today was the afternoon class. We learned how to use chisels. It has two surfaces one of which is flat and another one has a steep angle. The former helps the chisel go straightly down to the surface, the latter tends to push against the materials like woods we use.
- the slower I chisel, the better result I will get.

Our tutor was matthew in the afternoon. He is way younger than the other tutors.
