Universal CNC Axis

Intro

The following is a 5/16" or 8 mm version of the universal CNC axis described at http://opensourceecology.org/3d-printer-construction-set-workshop/

Larger axes will also be built, up to 2" for heavy duty CNC machining, with plastic parts sandwiched between metal plate as a plastic/metal composite structure. See calculations for beam deflection at Heavy_Duty_CNC_Construction_Set.
