Grizzly G0704 CNC Conversion - Y Axis Ball Screw Assembly Installation - Video #6

In this video I'll be installing the Y Axis ball screw assembly into the G0704 milling machine.
Using a 3D printed shaft coupler to drill adapter, I spin the ball screw to test the axis for binding. I set the clutch on the drill to setting 3, which is so light you can stop the drill chuck from turning with just two fingers.

Edit: I'll be repairing/filling-in the section of the section of the hole that was cut too big to help protect the ball-screw from falling chips. Will also add an additional way cover to keep chips out of the (remaining) new hole that's been created.
