Push Rod Fabrication Details:

Here are some notes for this low mass, high strength magnetic ball joint:

I ended up with these components:

-Countersunk super-magnets (opposite magnetic polarization direction)

-Small center magnet

-Cut-off magnetic steel screw head

Bringing them together into a high-force magnetic structure:

High strength longitudinally oriented carbon fiber tubes - Honed to accept magnet stacks.

Cleaned and epoxied in place. Digital calipers used to ensure equal spacing:
