Quarter sawing

The video below showcases how logs are quartersawn today. Long ago there was another method known as true quarter sawing. This term was taught to me by old timey sawyers. True quarter sawing is a very labor intensive and rarely is it cut today. True quarter  sawing involves every board to first be angled and a wedge cut. The wedge varies in thickness but often it can taper from zero at the center of the tree to 1/4 of an inch thick on the bark side. This method of cutting allows the maximum medullary rays to appear.  This form of quartering especially in oak is known as tiger oak. I was lucky enough to cut a log using this method and I must say it is by far the best method.
