I've been watching some carpentry videos on Youtube and found one featuring Larry Haun. Evidently, he is the crown prince of framing carpenters. He had it down to a science. He wrote books about it and everything. At 79, he and his brother could still frame an entire modest sized house in one day. He could drive 16 penny nails with one blow. It is a joy to watch them. When flying through a framing job, he was fond of saying " If your cut is not quite perfect, oh well, life goes on." I like that.
