New Cascading X-Rail Slide Kit

The new Cascading X-Rail Slide Kit provides all the mechanical pieces necessary to build a winch-driven extendable arm.  Fasten a motor or HS-785HB servo to the first stage of the slide kit and spool up the provided synthetic cable to get up to 34.5" of arm extension!  This kit uses bearings throughout - each stage is supported by 4 Mini V-Wheels that lock into the chamfered guides of the X-Rail.  The synthetic cable is routed over ultra smooth v-bearings so the torque provided by the servo or motor can be transformed into linear thrust rather than lost due to friction.  The arm, at full extension is rated for a 2lb load; perfect for adding a gripper or grapple hook.

Nicely done, and affordable too. Curious to see how people use it.
