Post Are Bent Trees of any Value ?

The modern concept preached by Forestry Gurus is that we should aim to produce tall straight timber presumably for turning into beams and planks however this could be somewhat misguided in that bent trees can sometimes outperform straight trees when it comes to producing a woodcraft work of art.

The lower hall roof of the citadel tower at Hikone castle in Japan makes good use of bent and wavy timber in a way that defies present day understanding of just how the selection and use of "sub standard" timber could have been envisaged and then put into practice.

Maybe we should take more care of our bent trees.

Does anyone have any good photo examples of trees with character growing in their woodland ?

That is a beautiful bit of craftsmanship!
I love this kind of work, modern buildings can be so soulless, with all its straight lines.

Didn't bent trees used to be used for sailing ships hulls?

Hi Secretary,

Yes once upon a time the navy employed timber cruisers to search the land for trees with approriate shape and size for use in shipbuilding. Trees were marked by them and these were then reserved for use by the navy becoming commonly known as "ship's timber". Many cottages are known to contain "ship's timbers" but very few of these timbers have ever been to sea with the designation really being more like a British Standard kite mark or these days a CE mark.

Nearly all of the timber leaving a woodland today is either destined for a saw or pulpmill with both of these users demanding straight timbers that will go through a fence to be fed into the sawmill or grinder. Maybe we should try to encourage carpenters and builders to visit our woodland to let them discover and wonder at the wide variety of shapes, sizes and species of timber that can be found such that they might get some inspiration to create modern buildings and structures that are also works of art.

The timber-framed roof pictured below was repaired by Steve Roberts with many of the replacement timbers being curved and used to best advantage to create a spectacular roof form.

The felling of larch logs for use in the OWG cruck timber-framed building project demonstrates some of the typical shapes of larch logs growing in a South Oxfordshire woodland.

Image

These are a mixture of straight, single plane curved, single plane double curve (ogee) and irregular stems.

Image

Laying the logs out together aids the selection, marking and cutting to length of each of the stems for use as specific building components.

Image

The lowest or butt section of a log contains the highest quality timber with little or no knots evident and only pin or small knots contained within the log arising from early growth suppressed branches. Logs cut from higher up the tree will contain a mixture of both dead and larger live knots which will limit their usefullness as primary structural components however these might be perfectly useable in a lower grade service like wall studs and rafters.
