What is green woodworking, and why do it?

Green woodworking is the method of taking a freshly cut tree, and splitting it along its grain to make furniture and other products. Typically a log of between 10cm - 25cm is used, and timbers such as ash, sweet chestnut, cherry, beech and oak are used. Many other timbers can be worked this way, with the notable exceptions of elm, Hornbeam, London plane and other trees whose grain is too interlocked to split successfully. Large diameter logs can also be split with enough helpers, some hefty mallets (or “beetles”) and a good quantity of oak wedges (or gluts).

There are any number of reasons for making furniture the way I do, but principal for me are the aesthetics of green wood furniture and the environmental and health benefits. There is something natural and honest about a piece of wood that has been cleaved from a round pole, and shaved by hand with sharp tools. The nuances of each piece - the undulations of grain, medullary rays on the radial faces, the sweep of the grain around a knot, or the beautiful ripples that develop under the tensile and compressive forces that build up on curves. With practice and a little luck these can be read in the log before it is split.

The main advantage of green wood is that it can be split.  When green wood is wet the lignin in it is soft, and allows the wood to split easily.  Dry wood is brittle when wet, and splitting it often results in cracking, rather than a controlled split.  This means you can retain the natural shape of the tree.  The saw is no respecter of grain, and just slices across it where it is told to.  Cleaved wood is stronger than sawn wood, as there is always a continuous line of grain running through the piece.  This means components can be made smaller in diameter, and consequently lighter. 

Green wood is usually bought from small, local woodsmen.  Using small diameter trees means it easier to transport, and energy costs are kept down further by converting it into component parts by hand.

Working wood green is a healthy, physically rewarding activity that can be carried out in the woods, workshop, or front room! There is no dust generated from cleaving and shaving, and the shavings can be put to use lighting fires, or providing mulch for the garden. I am experimenting with using mine as an environmental packaging material.

Green wood usually comes from coppice. Coppicing is a traditional form of woodland management which works harmoniously and sustainably with the natural environment. Young trees are felled, opening up the canopy and maintaining the root system of the tree. This allows dormant seeds on the woodland floor to germinate, creating habitat and food for a wide range of native species. New shoots soon sprout from the stump of the tree, and grow strongly, fed by the established root system. Coppicing is vastly superior in terms of bio-diversity to un-managed woodland. By parcelling up land into plots, the landowner can develop a sustainable business, whilst simultaneously providing a rich environment for native flora and fauna. I hand pick my stems from a well-managed local wood whose owner is always delighted his “wonky bits” are put to good use.

I love that I can be working outdoors, gaining fresh air and healthy exercise through my work. This is so different from working in a dusty, noisy machine shop. Making a living like this is not easy, but it can be done, with ingenuity, perseverence and a little luck.
