A comprehensive how-to manual of Polyface Farm's signature designs--with tips, tricks, and a half century of lessons learned through trial and error Have you wondered how to build the Polyface broiler shelter, or the dolly to move it, or an Eggmobile, Gobbledygo or Shademobile? For folks getting started, folks adding enterprises, or folks wanting a cheaper bootstrap way to build portable livestock infrastructure, Polyface Designs has all the diagrams and do-it-yourself building specifications. Joel Salatin wrote the text and Polyface former apprentice and engineer extraordinaire Chris Slattery did the drawings. Ultimately practical, the book includes how to build a corral, a home-made head gate and even how to select the right axle for your project. Square footage requirements for the deep bedding hay shed and area advice for pig pastures make this the definitive repository for a lifetime of Polyface experimentation. A massive volume, its 568 pages are in full color and beautiful enough to be a coffee table book even though you'll use it in your shop. Don't let the cover price scare you; one building tip can more than save the price of the book.
