Inside a Tapered Lamination
Lured by the dramatic look and technical challenges of curves, Enrico König (see the back cover) nearly always incorporates a deep bend in his furniture. The trick to pulling it off without sacrificing strength is to use laminations: The strength comes from the many layers and the rigid gluelines (urea resin glue or epoxy) between them. To avoid the arc looking clunky, he tapers it, and to do that without cutting through the plies, he tapers each one before laminating. König uses a tapering sled he saw in FWW #14 (Tapered Lamination by Jere Osgood; available at FineWoodworking.com/extras), putting solid-wood plies through a planer and bending plywood through a drum sander.
Simple sled. König uses a shopmade sled and a drum sander to taper the layers of bending ply.
