Traditional oak framing is still more craft than engineering for the simple reason that no beam is quite straight or square. Each joint is marked individually taking into account the peculiarity of the beams to be joined.
Cutting the joints will always be done by hand since with this marking method, each joint will be slightly different and joints cannot be cut one after another by machine. The result is a tight union between the two unique beams. We get a very high quality frame without having lost any of the individuality of the timber.
Using this 'gentler and less wasteful method' rather than having expensive machinery to plane timbers straight and square, means that our hand-made frames are really very inexpensive. Technology has come full circle!
