A. Symmetric Drawing Bow
large-diameter curves of a constant radius can be challenging, but drawing
more graceful elliptical curves can be downright daunting. Unless you
are an octopus, it is impossible to hold a thin strip of wood on edge,
bow it and hold it steady and to the desired curvature, while tracing
its shape onto your workpiece.
The Lee Valley Drawing Bow solves this problem. The bow itself is a strong,
but incredibly flexible, 1/8" x 1" x 4' long strip of glass-reinforced
plastic. The integral nylon strap has an easily adjusted buckle that can
be used to set the curvature you want and hold it. The torsional stiffness
of the bow resists deformation as you trace the shape. Made in the USA.
B. Asymmetric Drawing Bow
Unlike our regular drawing bow (above), this one lets you draw an asymmetric
arc a useful design element when making profiles for arm rests,
chair legs, and back rests. The bow tapers in thickness from 1/8"
to 1/16" over its length, so when bent it forms a curve of continually
changing radius. It works like a ship's curve. The 4' x 1" strip
of glass-reinforced plastic has an adjustable nylon strap and buckle so
the bow can be bent and held in the desired configuration.
Both are useful tools for furniture makers.
