ShimPart

To make sure that tight-fitting parts, such as the rockers (E) between the rocker brackets (F), remove easily when disassembling a project, use masking tape for a shim to provide a small clearance between the parts during assembly. For example, when mounting the rocker brackets to the cradle bottom (D), apply a piece of tape to each face of the 1⁄2" spacer (used in place of the rocker for clamping ease), and then clamp the brackets to the spacer. The two pieces of tape provide a total clearance of approximately .010"—just enough so that the rockers are not loose but will slide out easily.
