http://thegeekgroup.org/ - Woodturning rockstar Ralph Lindholm walks us through the process of turning a log into a bowl -- it is so much more than just grabbing a log and putting it into a lathe. Different angles and parts of the tree yield significantly different results. Grain direction and pattern can also come into play. Even just choosing what part of the log to turn from can have a significant impact on the final product. Turns out, there can be a lot of math involved too!
