The Essential Documents: What You Need to Read Before You Build These Projects

From the Founder, Pat Delany:

My role: to revive the original concrete lathe concept, to update the technology by 100 years and to shrink it from a ten-ton machine to one that will fit on an artisan’s workbench.

For instance, Yeomans used a still-secret (and highly toxic) metal alloy in his original construction, which we’ve replaced with non-shrinking cement grout — common worldwide. Our version also dispenses with Yeomans’ massive, industrial-scale alignment frames (jigs), replacing them with a method that can be used in a home workshop or by artisans in the developing world.

Replacing these two elements was not a simple task: it required four years of hard work to come up with solutions that are applicable NOW and around the world. Though our plans start small, they can expand: using our designs, someone could build a version as large as a railroad locomotive. This is a scalable solution to the problem of local manufacturing for local needs, since our version of the concrete lathe can work for a single artisan all the way up to a full-scale factory.

The following documents are absolutely key to understanding how to build the Concrete Lathe, the core piece of the Open Source Machine Tools project.
