The Multimachine

The MultiMachine, a humanitarian, open source machine tool
project for developing countries
Benefits
The MultiMachine all-purpose machine tool that can be built by a
semi-skilled
The Multi Machine

mechanic with just common hand tools. For machine construction,
electricity can be replaced with “elbow grease” and the necessary
material can come from discarded vehicle parts. What can the
MultiMachine be used for in developing countries?
AGRICULTURE:
Building and repairing irrigation pumps and farm implements.
WATER SUPPLIES:
Making and repairing water pumps and water-well drilling rigs.
FOOD SUPPLIES:
Building steel-rolling-and-bending machines for making fuel efficient
cook stoves and other cooking equipment.
TRANSPORTATION:
Anything from making cart axles to rebuilding vehicle clutch, brake, and
other parts.
EDUCATION:
Building simple pipe-and-bar-bending machines to make school furniture,
providing “hands on” training on student-built MultiMachines that they
take with them when they leave school.
JOB CREATION:
A group of specialized but easily built MultiMachines can be combined to
form a small, very low cost, metal working factory which could also
serve as a trade school. Students could be taught a single skill on a
specialized machine and be paid as a worker while learning other skills
that they could take elsewhere.
Features
How can an easily built machine tool that is made from junk be “all
purpose” and also accurate? Pretty simple! In almost every kind of
machining operation, either the work piece or the cutting tool turns. If
enough flexibility is built into the parts of a machine tool involved
in these functions, the resulting machine can do almost every kind of
machining operation that will physically fit on it. You may have heard
of 3-in-1 machine tools — basically a combination of metal lathe, mill
and drill press. The MultiMachine starts there but adds many other
functions. It can be a 10- in-1 (or even more!) machine tool that is
built by using vehicle engine blocks in a LEGO-like fashion. The
MultiMachine uses 6 unusual construction techniques to build 5 very
simple “modules” that bolt to a worn out or broken vehicle or industrial
engine block.

Using engine blocks as building blocks is the first MultiMachine
feature. Since cylinder bores are bored exactly parallel to each other
and at exact right angles to the cylinder head surface, MultiMachine
accuracy begins at the factory where the engine block was built.
The second MultiMachine feature is that in the most common version
of the MultiMachine, one that has a roller bearing spindle, this
precision is maintained during construction with simple cylinder
re-boring of the #3 cylinder to the size of the roller bearing outside
diameter (OD) and re-boring the #1 cylinder to fit the overarm OD. The
best part is that these cylinder-boring operations can be done in almost
any engine shop and at low cost. An engine machine shop provides the
most inexpensive and accurate machine work commonly done anywhere and
guarantees that the spindle and overarm will be perfectly aligned and at
an exact right angle to the face (head surface) of the main engine
block that serves as the base of the machine.
The third MultiMachine feature is that the spindle can be as simple
as a piece of pipe made to fit the inner diameter of the bearings.
The fourth feature is the addition of a third bearing to the
spindle. The three-bearing spindle is necessary because the “main”
spindle bearings just “float” in the cylinder bore so that the third
bearing is needed to “locate” the spindle, act as a thrust bearing, and
support the heavy pulley.
The fifth MultiMachine feature is our unique way of clamping the
engine blocks together. It’s easily built, easily adjusted, and very
accurate.
The sixth feature is a concrete and steel construction technique
that we resurrected. It was heavily used in industry during the first
world war.
