Rocker Box Plans $ 3.00
The Detailed Plans for Building a Rocker
The first part of this chapter discusses the operation and some of the uses of a rocker as well as a sketch of a rocker and some simple plans. It is conceivable, however, that some of our readers may want a more detailed plan of a rocker and the exact directions on how to go about building one. Although there are various sizes of rockers and a few slight variations in types, the one on which the plans and directions are given on the next two pages is a standard type rocker box. The average individual should, without too much difficulty, be able to build a reliable rocker from the diagrams and directions in this pdf file.
