is Rivened Wood?
Plainly speaking, rivened wood is wood that is hand split from
the log with an axe and froe, rather than cut with a mechanical
saw.
Hand riving causes the wood to split along its grain rather
than cutting through the grain as a blade would. It is the
strongest wood available, yet because it is rived, is the most
supple and flexible.
Cutting wood with a saw blade
exposes end grain along the lengths of the wood. When a piece of
wood is bent, such as the arm and bow of a sackback for example,
the end grain lifts and splits the wood rendering the piece
useless. In the interests of time, production and other
shortcuts detrimental to the structure of the chair, a chair
factory today laminates thin strips of wood together in the
shape needed. Commonly known as veneering, no one is usually the
wiser until the glue begins to fail, causing delamination of the
piece resulting in a very loose, or in a worst case, broken
chair.
Conversely, rivened wood is
an absolute straight-grained wood that readily bends once
steamed and because it is not glued, does not delaminate. This
is the method that original 18th century chairmakers
have use as far back as 1740. It is the same method that as a
trained master Windsor chairmaker, I still use today to make my
Windsor chairs.
Spindles shaped with a
drawknife and spokeshave from a rivened oak blank will bend and
flex with the stresses placed upon it. Spindles turned on a
lathe using a sawn blank, which factories use, will snap rather
than give.
I use nothing else but
rivened wood in all of my spindles arms, bows and crests.
