some timber has a crack at the end of them or somewhere, which means that they did not grow perpendicularly. In rain forest, some trees want to avoid tree shadow on them so they grow askew or curved, so those ones have tension themselves that appears as a crack when they are made into timbers and dehydrated.

There were some problems with machines. Table saw was not at a right angle because saw dust in the machine block the saw angle adjustment gear. Too much oil on the oilstones were problem as well. We can use overflown oil on the oil stone boxes. Chris is getting further when we use machine, he still gives us heaps of comments though. Every guy seems to be getting used to use chisel and also the other hand tools or machines. Mahogany is beautiful but is quite hard to handle it. I realised that the grain direction does not run constantly, so I had to change my position when I was chiselling and plaining. There was a small accident and we heard about physical information such as blood pressure and the mechanism of human healing system. I do not remember that a cutting hand tool which can cut nails.

After I come back home, I have done internet things like Autocad WS, screenr, etc. Those are connected each other in a complicated way, I am still confusing and not good at using them. Screenr was a good software, but it takes quite a long time to upload videos. Openproj is good as well, but I do not know how I can share the file. Picasa and Youtube are powerfull tools. I started using blogpost.

This picture is in my picasa web album. There are so many resources, softwares and programs on the cloud, it is hard not to be drown. We have to swim well~
