AT factory: Difference between revisions

This article deals around the tools frequently used in AT factories or workshops. Not all tools are generally required; it depends on the exact nature of material/device created in the AT factory; this as not all materials/devices are made in each AT factory. Instead, each AT factory specialises to some degree, and needed materials/devices for particular AT villages can simply be transported there when required. This allows each village to attain every type of material/device it requires, while still allowing the AT factories to operate efficiently.

Overview

The use of tools, and the ability to make them using local resources and equipment, are certainly very important in any appropriate technology effort. In some areas where small blacksmith shops, foundries, woodworking or machine tool workshops exist, many of the tools and processes covered in these books may have been in use for many years. In other areas, most of these crafts and skills are unknown. Therefore, the tools found in this category are of many different types, from simple hand tools to wood-turning lathes to metalworking equipment. Some may be made at the village level, others may require metalworking shop facilities.
