1、 MultiMachine, an open-source machine toolThe MultiMachine - a complete machine shop inone tool. Entirely built from scrap material.Pat Delany MultiMachine Box 1629, Palestine, Texas 75801 USA 903 723 0980Support at: http:/ The MultiMachine is a multi purpose machine tool* that a semi-skilled mechan
2、ic with just regular hand tools can build using scrap car and truck parts. Electric power is not needed.In Developing Countries, the MultiMachine has the potential for saving or improving the lives of many thousands of people. These machines can be used in many ways:In the health sector by its use i
3、n building water pumps, filters, water well drilling rigs and hospital furnishings. In agriculture by its use in building farm machinery and irrigation pumps. In transportation by its use in building and repairing parts for vehicles. In communications by its use as as a cell phone charging station.
4、In village life by being a source of battery power for home lighting. In education by providing vocational education students with machine tools that they build themselves and then are able to take back to their villages when they graduate.It could provide a local self supporting infrastructure that
5、 would be available to keep water and irrigation pumps in repair. Many NGOs go to great effort and expense to drill water wells and provide pumps in rural areas of underdeveloped countries. These pumps often fail because there is no person able to repair them. A small MultiMachine based business cou
6、ld provide a pump repairman with the means to earn a living in an area where these pumps and wells are used. The pump repairman could support himself by doing machine shop type jobs like making and sharpening agricultural tools and equipment and resurfacing vehicle flywheels, brake drums and disks.M
7、achine tools often draw power intermittently from gas or diesel engines or electric motors. Any surplus power could run a welding machine built from a vehicle alternator and also recharge batteries that in turn could be used for home lighting or recharging cell phone batteries.The combination of a M
8、ultiMachine and a welder can be used to build different types of metal bending and rolling machines that can be used to manufacture fuel efficient cook stoves, pots, pans and similar products.The MultiMachine also provides a way to machine simple zinc and aluminum castings made from the metal found
9、in old car parts. Without this machining, the castings are of limited use but simple machining can turn them into hundreds of different kinds of products.Vocational education takes “hands on“ learning. Few vocational schools in developing countries have sufficient numbers of the machine tools that a
10、re necessary for training students. This is no problem with student built MultiMachines.* A machine tool is a powered mechanical device, typically used to fabricate metal components2Look around you. Almost every manufactured product that is made of metal is a combination of parts that have been mach
11、ined (castings, screws and bolts) and sheet, bar and tubular metal that has been welded, bent, rolled or spun into a needed shape. The essentialy free MultiMachine and the tools it can produce can do all this.A group of specialized MultiMachines can do much more. The MultiMachine can be easily built
12、 in dozens of special versions that are specially built to do just a single type of metal working job. If these special machines were grouped together and driven from a common power source, they could be used in a form of Developing World mass production. Most of these machine versions could be buil
13、t with just one or two broken vehicle engines, a piece of pipe, a few feet of steel bar, a sack of cement and a few easily made zinc/aluminum castings.I am certain that MultiMachine newsgroup members will help adapt our designs to the types and sizes of material available in any community.Special th
