As we were handed a drawing yesterday about a tool box yesterday, we kept talking about the tool box. Christopher Lovegrove, who has shaggy beard with low tone voice, was a tutor today until the next day. He told us about features of timbers such as brittle(more likely to crash than to bend), end grain, sanded, mill, planks, westerned red cedar, slow growing, specific gravity weight(S.G.), the metric system, flat sawn, quarter sawn. Also three different type of drawing was told, which is profile(buttock line), bodyplan(station line), half breadth(water line), also diagonal line, table of offsets as well.
I should have brought a camera with me...because of many machines that cannot be explained in several words. Anyhow, there are quite a lot of machines like band saw, drop saw, circular saw, buzzer(surface planer), spider saw, thicknesser, router, spindle sander, a couple of grinders, etc in the building.
The thing that annoys me about the class is the terms some of which I cannot remember at the moment but probably have heard in Korean before. RS(rough sawn), D1S(Dressed 1 side), D2S, D3S, D4S. In the morning, prior to choose the best timber we caculated how many planks are going to be needed, which is called making cutting list. Items are arranged in rows and length, weight, thickness are arranged in colomns respectively.
He told us hand tools with demonstrating and explaining, such as combination square, sliding bevel(bevel square) for copying and pasting a certain angle, back saw, folding rules, chisels, spokeshare, electric saber saw, rasps, files, oilstone, clamps, c-clamps.
And he gave some tips.
- when using spider saw, make sure do not let the gap between timber and the shelf of it by pushing the timber down.
- when choosing timbers, check nails of bullets stucking in the timber, if so get rid of it.
- cut the end of the timber as it is usually dirty and rubbish.
- do mind your fingers where they go and always concentrate on your finger when machining, do not look around ever.
- before machining, turn on the extracting switch.
- if someone is machining, the others have to look after his or her back
- make your clothes of accesories neat
- do not put your hand at the end of the timber
- do not put timbers in a wrong(opposite) way -- critical
- when using buzzer or thicknesser, make the timber as thick as possible(mind the margin)

here are some other terms
- right angle grain
- tangential crack
- cupping
- flat(something special symbol marking on the surface of timbers)
- etc

I think one thing that should be prepared 1st is language. I suppose It was about 30% that I clearly understood my tutor's speaking. Not only was he talking about the theory or instruction but also he was joking many times. Then everybody laughed except me, which is a sad story....so I think the more practicing or preparing language, the more information you obviously get.
