Unique double clutch speed chuck key gets a test run.

Had a few hundred rollers to machine using my home made gang tools. It was a good time to see how the double clutch key worked and whether it would reduce the common elbow strain. It proved surprisingly comfortable throughout the run, allowing the ideal handle positions for both opening and closing the chuck.

Holy moly those travel moves are stressful but efficient. Just don't move your tools. Sweet chuck key.

It is a Proturn slx1630 with home made gang tool modules.

So *what* am I supposed to see, here? You're testing a.. double-speed chuck key?
Sorry, not getting it

The chuck key has a double ratchet. Push it in and it closes the chuck clockwise and free spins ccw. Without pushing in it opens the chuck ccw and free spins cw. The idea is that the optimum handle position can be found for both opening and closing without removing the key regardless of the chuck square hole orientation.
