09082011(instruction about table saw & grinder & oil stone by Christopher)

Lance brought a special plane that make drip groove(weather groove), which is given by his grandfather. He said his grandfather was also a boat builder. Christopher brifly explained to us about it. The surface of joint(glueing area; faying surface) increases by making rebate whereas butt joint tends to slip or split up. We did not do any practicing today. The class tomorrow is going to be with laptop.
