A self contained linear motion component we've been playing with.

Instructions are incomplete, because this is just a prototype, but it should be pretty self-explanitory if you open up the model.

It isn't perfect, but it's coming along.

Intended to use SDP-SI A 7Z 7-031 thrust bearing at either end (or other size appropriate to your lead screw)

This is still an early beta. There is a proof of concept here: http://brainspl.at/leadscrew-actuator/index.html http://www.youtube.com/watch?v=-VnTqqkmQ2E
