Design
Flexure was designed using CoMeT, (Compliant Mechanism Tool), developed in-house in MIT, by Marcus and Ani.
CoMeT User Guide
CAD
Marcus transferred specifications from CoMeT to existing CAD model, noting most excellently that the current square on the lead-swrew flexure connection was too big to fit inside the lathe body.
After conversation with Prof Culpepper, arm had to be added again to attach flexure with rails - this was so that a bushing could be used to constrain the rotation of the carriage.
Final part and drawing by Martin, 11th May (links to be updated later):
Flexure
Ready to be waterjetted, needs 1/2" aluminium.
Teflon Nut

- Note: Uses 1/4"-20 screws in all holes inlcuding those added by Martin to connect to flexure.
