Group Description

Doing something for the world with machine-tool making techniques from the 1830s to the 1960s.

Your developing world school needs almost-free machine tools?

Your developing world factory needs unavailable spare parts?

You need a complex part that is too expensive to have made?

Need to bootstrap a factory but only have a few bucks?

No problem!

First came the Multimachine, a home-built milling machine that could be used as an all purpose machine tool. It was a 2007 Popular Mechanics DIY project of the year and the centerpiece of Maker Faire Africa in 2009. It could be be built using only automotive scrap and steel bar. IT CAN PERFORM ALMOST EVERY METAL MACHINING OPERATION!

Our latest project comes from a forgotten but prize winning design for a 1915 cannon shell making machine that was made from concrete. It is a general purpose screw cutting metal lathe (the basis of all industrial production) that is built using only concrete mix and scrap.

Only a very small amount of welding, regular carpenter's and mechanic's tools and a $10 dial test indicator are needed.

Serious about building machines?

REALLY STUDY THE FILES ON THESE RELATED SITES OR YOU COULD END UP WITH A USELESS PILE OF CONCRETE AND SCRAP!!!!

Sorry that the information is so spread out but Yahoo Groups had serious space limitations until recently.

READ the "How to Build a MultiMachine" booklet at the top of the list in the "Files" folder.
