Today I began work on a very small walnut chest of drawers with sides that taper toward the top. "How does one make sides that taper toward the top?" You ask.
It is simple, as shown in the photo above. A block of wood attached with double stick carpet tape under one end allows the wood to pass unevenly through the planer, taking off more at one end than the other. It takes several passes through the planer to get this result.
