Special Techniques, (Cont'd)

FIG, A

Kerf bending is one of the three most common wood bending techniques, the others being steam bending, and laminate bending. Although kerf bent material does not have the tensile strength of either steam or laminate bent material, the kerf bending process is far less time consuming and complicated. Moreover, most hobby woodworkers simply do not have a steam box. Therefore, kerf bending is an alternative that many woodworkers will find especially useful.

By modifying the kerfing technique, kerf bending may be used to create elliptical or even spiral curves. A spiral curve can be produced by cutting the kerfs at an angle (Fig. 5).

Compound curves can be formed by alternately kerfing both sides of the wood. When bending severe or complicated curves, soak the wood in warm water to ease the bending process.

Kerfing is usually done across the grain, however, occasionally a piece of wood with a bend only at the end will be needed. By cutting the kerfs into the end grain, then gluing veneer strips into the kerfs (Fig. 6) the board can be easily bent into the desired shape. Clamp the piece while the glue sets, and the curve will become permanent.

Kerf bending is most often used to (continued on next page)
